The drawings illustrate, by way of example, an embodiment of the invention as used in connection with a forty-five calibre automatic Colt pistol I. The combined magazine and extension stock element is in the form of an elongated hollow body 2 having an up-turned forward end. The body 2 provides a magazine 3 designed to carry forty cartridges. A clip for holding forty cart-ridges for reloading is indicated at 4 (Figure 20). It is to be understood however, that the capacity of the magazine 3 may be as desired and that the capacity of the clip 4 may be other than that as stated. The capacity of the magazine preferably is always greater than that of the magazine of the pistol. When it is deemed necessary to fire more cartridges than the pistol carries, as regularly manufactured, the operator removes the magazine from the pistol and inserts the upturned end of body 2 into the handle of the pistol whereby the larger number of cartridges carried by body 2 will successively and automatically be supplied or fed, by a means to be hereinafter described, to the pistol to be fired. In this connection attention is directed to Figure 2. The forward end of body 2 isnotched, as at 5, for the reception of the pistols magazine retaining means 6, of known form, for coupling end portion to handle 1 of pistol I. The body 2 is of rectangular conto in vertical section.
The b dy 2 consistsof leading and follower parts 8, 93 The part 8 is of less length and thickness than that of and extends upwardly at a forward inclination with respect to the part 9. The major portion of the length of part 8 is to be extended into, connected to and snugly fits the pistol handle I. The notch 5 is formed in the part 8 in proximity to its upper end. The part 8 is anchored at its rear end, as at It), I I, to the forward end of part 9 and the inner face of part 8 forms a continuation of the inner face of part 9. The notch 5 is formed in the front edge of part 8. Arranged within part 8, in proximity to the inner face of the rear edge thereof, is a roller 12 (Figure 2) constituting a trip for shifting the cartridges from a position inclined to the horizontal as the cartridges enter the body of the pistol. The roller I2 is arranged at the upper end of part 8 and is disposed at right angles to the path of travel of the cartridges. The roller I2 is arranged above the notch 5 and is journaled in the sides of part 8. The sides of part 8 are crimped inwardly and lengthwise thereof in proximity to the rear edge of part 8 to provide spaced parallel cartridge guides l3, l4 extending from the rear end of part 8 to a point in close proximity to roller l2.
The part 9 is substantially of triangular contour and has an upstanding, curved forward end terminal portion which abuts and is anchored to the part 8 as indicated at III, II. The part 9, for the major portion of its length, has a straight top edge and an inclined bottom edge. The rear end of the part 9 is rounded. The part 9 includes a pair of side cheeks I5, IS, a top member I! and a bottom member l8. The side cheeks gradually increase in height from a point in proximity to their forward ends to their rear ends. The side cheeks l5, l6 are arranged in parallel spaced relation and the top and bottom members l1, l8 are arranged between the side cheeks and flush with the edges of the latter. The side cheeks I5,
IS, in proximity to their rear ends, are formed with large openings I9, 20 respectively, of the same diameter and arranged in parallelism. The side cheek l5, forwardly of the opening I 9 is provided with an opening 2| of materially less diameter than the opening l9. The side cheek I6, forwardly of the opening 20, is provided with an opening 22 of greater diameter than the opening 20. The inner faces of the side cheeks l5, l6 are provided with annular rabbets 23, 24 which border the openings I9, 20 respectively, at the inner ends of the walls of said openings. The side cheek I has its inner face formed with a rabbet 25 which borders the opening 2| at the inner end of the wall of the latter. The side cheek I6 is formed with a stepped rabbet 25 which borders the opening 22 at the inner end of the wall of the latter. Positioned against the inner faces of the reduced rear terminal portions (Figure l) of the side cheeks l5, l6 are plates 21, 28 respectively, formed with rounded extensions 29, 3|] respectively, at their forward ends. These extensions are spaced from the top and bottom edges of the plates. The extension 29 is mounted in the rabbet 25. The extension 30 is mounted in the largest stepped portion of the rabbet 26. The top and bottom members l1, l8 are arranged between the plates 21, 28. These plates are arranged at the rear end terminal portions of the side cheeks. The plates 21, 28 are formed with openings 3|, 32 respectively. The extension 29 is formed with an opening 33 which aligns with but is of less diameter than the opening 2|. The extension 30 is formed with an opening 34 which aligns with the opening 22. The plates 21, 28 conform in contour to the rear end terminal portions of the side cheeks l5, IS.
The plates 21, 28 are formed with spaced parallel like annular channels 35, 36 respectively of less diameter than the height thereof. The upper portions of these channels are arranged in proximity to the top member l1. The rear portions of these channels are spaced forwardly of the rear ends of the plates 21, 28. These latter are formed lengthwise thereof with spaced parallel like grooves 31 inclining upwardly from rear to front and extending across the lower portion of the channels 35, 36. The grooves 31 are of a length to extend through the extensions 29, 39. The forward end of the grooves 31 register with the rear ends of parallel spaced grooves 38 formed in the inner faces of the side cheeks |5, H5. The grooves 28 are disposed at the same inclination as the grooves 31.
Mounted in the grooves 31, 38 is a cartridge suspension and guide element 39 which extends from a point forwardly of the rear end of the grooves 31 to the forward end of the grooves 35.
The element 39 is of inverted channeled contour formed with oppositely disposed inwardly extend ing flanges at the bottom of its sides. The forward end of element 39 is at the forward end of the part 9 of the stock and the flanged sides register with the-guides l3, I4 formed in the part B of the stock. The guides |3, |4 form flush continuations of the flanged sides of the element 39. The latter, on the portion thereof which is arranged in the grooves 31, has rigidly secured thereto a pair of blocks 49, only one shown. These blocks 40 are rigidly secured to the plates 21, 28. The top of the rear end terminal portion of the element 39 is cut out,.as at 40, to provide a clearance for a purpose to be referred to. The element 39 divides the part 9 of the stock into a lower chamber and an upper chamber. The
lower chamber coacts with the part 8 of the stock to provide a part of the magazine 3. The upper chamber is indicated at 4|, is of triangular contour and is adapted to receive the cartridge pusher or feeder mechanism, to be referred to, when such mechanism is inactive and it is also employed for permanently receiving a stretch of the pulling element, to be referred to, for such mechanism. The upper chamber 4| communicates at its forward end with the magazine 3 adjacent the rear end of the part 8 of stock 2. The chamber 4| opens at its rear into the rear end of magazine 3.
The members l1, l8 not only provide closures for the top and bottom respectively of the part 9 of the stock, but also spacers for the side cheeks l5, H5. The cheeks I5, l6, members l1, l8 and plates 21, 28 are rigidly secured together by the holdfast devices 42. The plates 21, 28 are also secured to the inner faces of the cheeks I5, It by the holdfast devices 43. The top member l1 has a depending curved end terminal portion 44 arranged between the upper portion of the rear ends of the plates 21, 28. The end edge 45 of the member l1 constitutes the top wall of a door opening for the magazine 3. The rear end edge 46 of bottom member I8 is spaced forwardly from the rear ends of plates 21, 28 and provides the bottom wall of the door opening for the magazine 3. That portion of the plates 21, 28 arranged between the said ends 45, 46 constitute the side Walls of the door opening for the magazine 3. The door opening is indicated at 41, Figures 3, 4 and 10. A curved spring controlled, automatically latchable and releasable door 48 is arranged between the plates 21, 28 and is employed for closing the entrance to the magazine 3. The said entrance is formed by the opening 41. The door 48 is mounted at one end upon a pivot 49 arranged in close proximity to the end edge 46 of member IS. The other end of the door 48 slidably engages the end edge 45 of member l1 when the door is in closed position. Attached to the inner face of the door 48, as at 50, is one end of a curved controlling spring 5| normally tending to project the door from opening 41. The spring 5|, when door 48 is'closed, bears against an abutment 52 carried by plates 21, 28. The abutment 52 is arranged above the grooves 31. The inner face of door 48, in proximity to its non-pivoted end, is formed with a nose 53 for engagement by a pivoted spring controlled upstanding automatically releasable latching member 54 for holding the door 48 closed. The member 54 (Figure 16) includes a rectangular body 55 formed at its lower end with a rearwardly directed hook 56 and at its upper end with an upstanding forwardly curved shank 51. The upper end of body 55, at each side of the lower end of shank 51, is formed with a rearwardly directed barrel 58. The bar- I rels 58 are loosely mounted on a pivot shaft 59 carried by the plates 21, 28. Secured to the inner face of the terminal portion 44 of member l1, as at'60, is a controlling spring 6| for the latching member 54. The spring 6| permanently bears against the rear face of shank 51 and tends to shift member 64 on its pivot in a direction for the hook 56 to engage nose 53 to latch door 48, as shown in Figure 10.
Anchored within, as well as extending outwardly from the openings I9, 20, is a pair of oppositely disposed spaced parallel caps 62, '63 respectively, having axial openings 64 surrounded by bosses 65 arranged on the inner faces of the caps. Journaled in the openings 64 are the ends of a power transmitting shaft 66 which is driven from a spring motor 61 arranged within a revoluble drum 68 disposed in chamber 4|. The drum 68 revolves about shaft 66. The motor '61 is in the form of a windable and unwindable coiled power transmitting spring 69 which encompasses and has-one end fixed to shaft 66. The spring 69 has its other end fixed to drum 63. The latter is arranged between the caps 62, 63, abuts the boss 65 on cap 62 and is spaced from the boss '65 on cap 63. The sides of the drum 68 are axially apertured, as at 18, for the passage of shaft 66. Interposed between drum 68 and the boss 65 of cap 63, as well as being fixedly secured to shaft 66 to bodily move with the latter, is a grooved power transmitting pulley 1|. The body of drum 68 has its outer periphery formed with a pair of spaced annular ribs 12 to form the drum 68 with a circumferential groove 13. The cut out top 48 of the rear terminal portion of element-39 forms a clearance for the bottom of drum 68.
Winding off and on the drum 68, relative to groove 13, is a flexible pulling element 14 upon which is attached a flexible cartridge pusher or feeding device or mechanism 15. The element 14 is of strap or tape-like form and has one end attached to drum 68 within groove 13. The ele- -ment 14, when winding off the drum 68, travels through the element 39 to cause the device 15 to feed the cartridges. the drum 68 on the return of the device 15 to its initial position. The element 14 travels from the rear portion of chamber 4| into and through the element 39 and from the latter into the forward end of and rearwardly in chamber 4| on the feeding of the cartridges. After all the cartridges have been shifted into the part 8 of the stock 2, the device 15 is shifted rearwardly relative to element 39 and element 14 is returned to the full line position shown in Figure 11. The rearward shift or travel of element 14 relative to element 39 is provided by the winding up of the spring motor 61 by a means to be referred to.
The device 15 consists of a curved leading carriage 11 provided with a friction roller 18 projecting outwardly therefrom, a pusher member 19 secured to the leading end of carriage 11 and extending outwardly from said end at an angle thereto, a setof spaced curved follower carriages 88 provided with friction rollers 8| projecting outwardly thereof, a set of spaced cur-ved links 82 arranged between and pivotally connected at their ends to the follower carriages 88 and a curved link 83 pivotally connected to the front end of the leading carriage of said set of follower carriages 88 and to the rear end of carriage 11. The ends of the carriages are bifurcated and the links are extended into the furcations. The carriages, when the device 15 is inactive, are positioned against the ribs 12 and ride against these latter when the device 15 is moved from and to inactive position. The carriages ,have side flanges 84 which. ride on the upper faces of the inturned side flanges of the element 39 during the feeding of the cartridges and when the device 15 is returned to its initial position.
There is associated with the latching member 64 a shiftable releasing device 85 therefor which functions to release member 64 when the device 15 is being returned to its initial position, as shown in Figure 4. The device 85 consists of a band 81, of a contour greater than a half circle, which travels in the channels 35, 36. The rear end of band 81 has an extended reduced curved projection 88. The forward end of band 81 is squared. The fric- The element 14 winds on tion rollers 15, 8| bear against the inner face of the device 85 when the device 15 is in the position shown in Figure 10. The band 81, on its outer face, has a protuberance 89 for engaging stem 51 and rocking member 54 to move hook 56 clear of nose 53 to permit spring 5| to shift door 48 open so that access may be had to the rear end of magazine 3 to enable the loading of the latter with cartridges. When the device 15 is moved from the position shown in Figure 10 it carries the band 81 therewith in a direction to have protuberance 89 clear shank 51 whereby member 14, due to spring 6|, will be carried with device 15 until its edge 98 arrives at the closed portion 9| of the channels 35, 36. At this point a spring controlled latching device 92 will engage the edge 93 (Figure 10) of band 81 and act to prevent the latter being shifted accidentally in the other direction until it is moved in such direction on the return of the device 15 to its initial position. The device 92 is arranged forwardly of band 81 and is mounted at one end on a pivot 94 carried by plates 21, 28. The controlling spring of device 92 is indicated at 95. The device includes a curved offset portion 96 to engage edge 93 of band 81. The device 92 is arranged in chamber 4|. On the return of the device 15 to its initial position (Figure 4) the pusher member 19 engages the projection 88 and causes the band 81 to move from the position shown in Figure 10 to that shown in Figure 4. As the band 81 is moved by the pusher member 19, the protuberance 89 will ride against shank 51 and will release and hold latching member 54 in released position relative to nose 53, and in this connection attention is directed to Figure 4.
The pulling element 14, when operating to pull the device 15 for the purpose of feeding the cartridges, is wound on a winch 91 which is operated, during the firing of the gun, from the pulley 1| by a power transmitting strap 98. The winch 91 includes means for driving the strap 98 for the purpose of operating the pulley 1| in a direction for winding up the spring motor 61 and thereby unwinding the element 14 from oif the winch and shifting the device 15 to its initial position, Figure 4. The winch 91 includes a cap 98 which is arranged within and extends outwardly from opening 23. The cap 98- extends into the opening 34 formed in the extension 38. The cap 98" is anchored to cheek I6 and is formed with an axial opening 99 and a boss I88 on its. inner face surrounding opening 99. Arranged within and extending inwardly from opening 99 is a bearing sleeve |8|. Mounted in the opening 33 of the extension 29 and extended outwardly and inwardly with respect to the latter is a tubular bearing I82 formed with a peripheral annular shoulder I83 which, at its outer side, abuts the inner face of extensions 29. Positioned against the boss I88 is a grooved pulley I84 of greater diameter than pulley 1| and which functions as a driven pulley during the cartridge feeding operation and as a driving pulley when the cartridge feeding device 15 is being returned to its initial position. The pulley I84 includes inner and outer webs I85, I86 respectively. The web I85 has an axial opening I81 for the purpose of revolubly mounting pulley I84 on the sleeve I8I (Figures 6 and 7) The web I86 is in the form of an annulus having its inner edge threaded, as at I88. The said inner edge of the web I86 is arranged outwardly relative to the opening I81 in web I85. The inner diameter of the web I86 is materially greater than the diameter of opening I81. Formed integral with the web I06 is an internally threaded collar I09 projecting towards the extension 29 on plate 21 and having its threads forming a continuation of the threads I08. Mounted on the bearing I02 and having one side abutting the other side of shoulder I03 is a grooved drum IIO which extends from the inner end of bearing I02 and revolves on the latter during the cartridge feeding operation. The drum H at its other side is formed with an annular flange III having its outer face threaded, as at H2. The flange III has a reduced outer edge portion I I3 formed with spaced teeth II4 constituting a clutching edge. The internally threaded collar I09 of the pulley I04 threadedly engages with the threads of the flange II I for securing the drum H0 and pulley I04 together so they will revolve in unison when the drum H0 is driven clockwise and anticlockwise. The front edge of shoulder I03 of bearing I02 if formed throughout With ratchet teeth II5 for a purpose to be referred to. it manually r0- tatable shaft H6 is extended through opening 2| in the cheek I5, through bearing I02 and into sleeve IOI. The shaft H6 is fixedly secured to sleeve IOI by a pin H1. The shaft H6 is formed of a circular part IIB recessed in its outer face, a cylindrical part H9, a Worm part I20 and a cylindrical part I2I of less diameter than the part H9. The worm part I20 is interposed between the parts II9, I2I. The outer end of part I I9 merges into the inner face of part H8. The latter abuts the outer end of bearing I02. Threadedly engaging with the worm part I20 of shaft H6 is an interiorly threaded adjustable flanged coupling collar or nut I22 having its flange I23 opposing the web I05 and formed with spaced teeth I24 to coact with the teeth II4 to clutch the drum IIO to shaft II6 whereby when the latter is rotated, the drum H0 and pulley I04 will be driven from shaft H6. The latter is not rotated when pulley I04 is opearted from the transmission strap 98. Surrounding the shaft I I6 and interposed between bearing I02 and collar I22 is a coiled spring I25 normally tending to hold the collar I22 out of mesh with the teeth H4. The normal position of collar I22 is as shown in Figure 6 and it is moved into clutching engagement relative to the teeth II4 on theclockwise movement of shaft II6. Pivotally connected to and seated in the recessed outer face of the shaft part H8 is the end I26 of a crank handle I21. The pivoted connection between handle I21 and shaft part H8 is indicated at I28. The side cheek I5 is grooved, as at I29, to receive handle I21 when the latter is in non-extended position. The crank portion of handle I21 is at the end I29 of the latter, is indicated at I30 and is for extension through an opening I3I in cheek I5 to engage a resilient latching device I32 arranged in chamber 4| and anchored to the side cheek I6.
The top member I1, in proximity to its forward end, is formed with an opening I33 which registers with an opening I34 provided in the top of element 39. Secured, as at I35, I36, to the member I1 is an upstanding open bottom casing I31 which provides a chamber I38 communicating through the openings I33, I34 with the magazine 3 and through a slot I39 formed in member I1 with the chamber 4I. Rotatably supported by the sides of the casing I35 and arranged within the chamber I38 is a guide pulley I40. The latter extends into the opening I33. The pull'ing element 14, during the cartridge feeding operation, travels from the element 39, through the openings I33, I34 into the chamber I38, against the bottom edge, upwardly against the forward edge and rearwardly over the top edge of pulley I40 and thence rearwardly through slot I39 into chamber M and winds on the drum of winch 61. When the device 15 is moved to its initial position in chamber M, the pulling element 14 winds off winch 61, travels forwardly through slot I39, over the top edge, downwardly on the front edge and rearwardly against the bottom edge of pulley I40, thence into element 39, rearwardly in the latter and from the rear end of element 39 into chamber 4| and winds on the drum 68,
The pulling element 14 has its upper face provided with means, as at I4 I to constitute consecutively numbered indicators to indicate the number of cartridges which have been fired and such indicators are successively visible through a. slot I42 formed in the top of casing I31.
The top member I1, at its forward end, is formed with a pair of spaced parallel apertured ears I43, only one shown, and arranged between them is an apertured extension I44 on the rear end of the rear side of part 8 of stock 2. Extending through the ears I43 and extension I44 is a coupling or connecting means I45. The bottom member I8, at its forward end, is cut out, as at I46, and secured within and extending outwardly from the cutout I46 is a shock absorber I41. The latter includes a laterally disposed block I48 having its inner part anchored in cutout I46. The outer part of block I48 has formed in'its top a socket I50, in its bottom a socket I5I and a bore I52 connecting the sockets together. Extending through the sockets and bore is the shank of a headed bolt I53. The head of the latter is arranged in socket I50. Surrounding the shank of bolt I53 and interposed between the head of the latter and the base of socket I50 is a resilient or cushioning member I54. The lower end of bolt I53 carries a holding nut I55 and surrounding the shank of bolt I53 and interposed between the nut I55 and base of socket I5I are superimposed resilient or cushioning members I56. The head of the bolt I53 has extending outwardly therefrom an apertured ear I51. 1
The rear end of the forward side of the part 8 of the stock 2 has fixedly secured thereto a laterally extending block I58 formed with a pair of spaced parallel apertured ears I59, only one shown. The ear I 51 is positioned between the ears I59 and said ears I51, I59 have extending therethrough a coupling or connecting means whereby the part 8 is not only coupled to part 9, but is also coupled to the shock absorber I43. The latter has the bolt I53 thereof disposed at an opposite inclination with respect to the inclination of part 0 of stock 2, whereby bolt I53; when acting, in connection with the members I54, I56, to absorb shock, will shift in a plane intersecting the plane of the part 8 of the stock 2.
The cartridge clip'4 for use in loading the magazine (Figure 20) will be of a capacity preferably for holding forty cartridges. The clip consists of a channel-shaped body I6I of the desired length and width, having its body out out at each side of one end terminal portion to form a resilient tongue I62 which normally inclines from its inner to its outer end in a direction towards the inwardly extending flanges I63 on the sides of the clip. The other end of the body of the clip is formed with a stop flange, I64. When the cartridges I65 are mounted in the clip 4, they are held therein by the coaction of tongue I62 with the flange I63. The sides of clip I60 in cross section conform to the sides of the guide element 39. When loading the magazine, the clip with the cartridges I65 suspended therefrom is extended into the magazine 3 from the rear of the latter to register with the rear end of guide 39. The cartridges I65 are forced from oh the clip at the forward 'end of the latter, which is that end provided with the tongue I62. As the cartridges are forced ofi the clip, the tongue I62 is elevated to enable the cartridges to clear the latter and enter the rear end of guide 39 which suspends the cartridges in that portion of the magazine in the part 9 of the stock 2, and with the cartridges clear of the sides and bottom of the said portion of the magazine. o
The shaft 66 is connected with the winch 91 in a manner whereby the latter will be operated in an anticlockwise direction from said shaft 66 when the latter is driven from the spring motor 61. The shaft 66, when operated from said motorv 61, moves in a clockwise direction. Due to the diameters of the pulleys 1I, I04 relative to each other and the diameter of the drum 68 being greater than that ofpulley 1I, there is a differential ratio set up which causes the winch 91 to wind thereon the pulling element 14, thus pulling the device 15 into the magazine and during such action the motor 61 operates shaft 66 in a clockwise direction and provides for pulling the element 14 from off drum 68 at a slower speed than that of shaft 66. When the feeder or pusher device 15 has traveled to the front end of the magazine 3, the handle I21 is extended and operated in a direction to rotate shaft II6 to an extent to provide for collar I22 clutching the drum IIO of winch 91 to shaft II6. When winch 91 is coupled to shaft II6 the handle I21 is turned in a clockwise direction carrying shaft H6 in a like direction whereby the drum III] and pulley Hi4 are revolved by shaft I I6 in a clockwise direction whereby the transmission strap 98 will operate shaft 66 in an anticlockwise direction and wind up the spring motor. A spring controlled pawl I66 is carried by the extension 29 of plate 21 and coacts with the teeth II5 to arrest the winch moving anticlockwise when shaft H6 is operated clockwise from the handle I21. When the winch 91 is operated in a clockwise direction it unwinds therefrom the pulling element 14 and permits the element 14 being wound on drum 68 to an extent to shift the device 15 from out of the magazine 3 into the chamber 4| and around drum 68 to the position shown in Figure 4.
Any suitable means may be employed for latching the spring motor from operating to drive shaft 66.
The rear of part 9 of the stock 2 is provided with loops or hooks I61 for connecting a shoulder strap, not shown, therewith.
The strap 98 is connected at its ends to the pulleys 1I, I04, alternately winds off pulley 1| and on pulley I04 when the spring motor operates 48. The sides I68 (only one shown) of the body top and bottom I69, I69 respectively, of the body of the stock. The strip I69 is mounted at its lower end on a pivot I10-carried by thesides I68. The inner face of door I61 will be formed in the same manner as the inner face of door 48. The door I61 will be automatically opened and latched in the same manner as the door 48.
Figures 27 to 31, both inclusive, illustrate a modified form of door structure and with reference thereto, the body "I of the stock is shown as including a pair of side walls or cheeks I12,
I13, a top wall I14-and a bottom wall I15. The
walls I14, I15 are arranged between the walls I12, I13. The said several walls are secured together by the holdfast means I16. The rear end of wall I14 is spaced from the rear end of wall I15. Arranged between the walls I12, I13 in the space between the rear ends of the walls I14, I15 is a combined door opening former and slidable door housing means I16 formed of a pair of oppositely disposed strap-like segmental shaped members I11, I18 of like form. Each of said members includes a narrow lower part I19 of inwardly opening channel-shaped form, an intermediate lower part I of inwardly opening channel-shape form of greater width than part I19 and having its inner flange I8I of less width than its outer flange I82, an upper intermediate part I83 of inwardly opening channel-shape form of greater width than the part I19 and having its inner and outer flanges I84, I85 respectively of the same width, an upper terminal part I86 having its lower edge grooved as at I81 and of greater width than part I19, and a lower terminal part I88 formed in its rear edge with a groove I88" and of greater width than part I19. The part I88 merges into the lower end of part I19. The part I80 merges into the upper end of part I19. The part I83 merges into the upper end of part I80 and the part I86 merges into the upper end of part I83. The part I19 is of greater length than any of the other of said parts. The part I83 is of greater length than the parts I80, I81, I88. The parts I80, I81, I 88 are substantially of the same length and of materially less length than parts I 19, I83.
The parts I19 of said memberscoact to provide a door opening I89 extending from the part I88 to the part I80. The outer flanges I82 of the part I80 abut. The flanges I8I of the part I80 are arranged in aligned spaced relation to form a slot I90 extended upwardly from the upper end of opening I89. The slot I90 has its lower end open and communicates with the upper end of the door opening I89. The inner and outer flanges I84, I85 of the parts I83 abut and form in connection with the flanges of the parts I80 a door receiving chamber I9I communicating at its lower end with the upper end of the doonopening I89. The upper end of chamber I9I is closed by the grooved lower edge I81 of part I86.
Slidably mounted in the means I16 is a door I92 for closing the door opening I89. When the door is in closed position, it is arranged in the parts I19 of the members I11, I18 and its lower end seats in groove I89. When the door is shifted to open position, it is moved into chamber I9l and its upper end seats in groove I81. The door is shifted manually to closed position and automatically to open position and to these ends respectively, the lower end .of the door has ex tending outwardly therefrom a handle I93 and has extendinginwardly therefrom, in proximity.
to its lower end, an abutment I94. The latter is arranged in the return path of the pusher member 19. The slot I90 provides a clearance for the abutment I94 when the door is shifted to open,
position by the member I9. The inner flange I95 of the parts "9 of the members I11, I18 are cutout as at I96 to form continuations of the grooves 31.
With reference to Figures 32 to 35 both inclusive, is a modified form of the leading part of the body 2. In these figures the said part is indicated at I91 and the form of the latter is such as to cause the cartridges before discharge to shift from their inclined positions into a horizontal position. The part I9! is permanently open at its outer or forward end and it includes a bottom wall I98, a top wall I99, 2. pair of side walls 29!), 2M and the cartridge guide means 292 arranged inwardly of and in close relation'to the wall I99. The wall I99 has its forward end positioned rearwardly'of and in spaced relation to the forward ends of the walls 290, 2! whereby the forward end of the bottom of part I 9i is formed with a cutout or opening 299. The forward end of wall I99 is arranged in forward relation with respect to the forward end of wall I98, but it is spaced rearwardly from the forward ends of the walls 290, 29I whereby the forward end of the top of the part I91 is formed at its forward end with a cutout or opening 294 of less depth than the cutout or'opening 203. The latter forms a-clearance for the cartridges when they are turned from their inclined position into a horizontal position. The cutout or -opening 20% provides a clearance to-permit of the cartrides turning or tilting from their inclined position into a horizontal position and to be discharged in such latter position. The wall I99 extends a short distance forwardly from the means 202, as at 295. The portion 295 is to be of less lengththan that of the diameter of the inner end of the cartridge shell. The forward end edge 206 of the wall I99 provides a fulcrum upon which the cartridges tilt, turn or fulcrum when moving from inclined position to horizontal position. As the cartridges are pushed or fed by the pusher mechanism the leading cartridge will be shifted clear of the means 292 onto and moved forwardly of the portion 299 until it reaches edge 296. The latter will then provide for the car- .tridge to fulcrum from an inclination to a horifollower membe .ends of members 209, as at ill.
