Granted: 1899-03-11
Abstract: 6274. Waite, F., and Waite & Saville. March 15. Platen presses.-Fig. 3 shows a side elevation of a machine more particularly for printing envelopes and small work. The forme is fixed on the underside of a vertically-reciprocating holder A, which prints the sheet on a platen B reciprocating horizontally in guides on the framing. The platen runs out under the feed-table C, and is provided with grippers which nip the sheet and draw it off the table as the platen moves under the bed. The grippers are pivoted in recesses near the sides of the platen and extend inwardly over its front edge. The table C may be lifted up on its pivot C' for making ready &c. The front edge of the table is lowered, to clear the sheet from the front gauge, by means of an arm C' and cam on the shaft H<6>. The platen is reciprocated by links connecting it to arms L on a shaft L<2> vibrated by a cam L<5> and spring L<7>. The platen is supported when in printing position by a fixed bed D. The sheets are removed from the platen by grippers E', E<2> on a carriage E, and are deposited on an endless band or the like. The carriage E is reciprocated by links N<5> and arms N operated by a cam on the shaft H<6>. A recess in the front edge of the platen permits the grippers E<1>, E<2> to seize the sheet. The inking-rollers J are in bearings resting in sockets J' on the platen and raised by springs J<4>. Ink is supplied in any usual way from an ink duct J<6>. The vertical slide carrying the bed A is raised by a spring, and is depressed to make the impressions by a toggle A<2>, A<3> the arm A' of which is fixed on a shaft P oscillated by an arm P<2>, and a rod P<3> connected to an arm P<4> operated by a cam P'. The impression is 'thrown-off' as follows:-The part of the type-bed slide on which the lower end of the toggle arm A<3> acts is movable and rests on a shaft R having a flat side, and when this flat engages the movable piece the type-bed is not depressed sufficiently far to make the impression. The shaft R is turned by an arm having a bowl R<5> adapted to engage the upper end of a tappet R<4> as the slide moves downwardly. The tappet is moved into position to engage the bowl R<5> by operating a lever T'.

Title: Improvements in Tools and Tool-holders for use in Lathes and other Machine Tools.
Inventor: MURPHY WILLIAM
Filed: 1898-03-28
Granted: 1899-01-07
Abstract: 7434. Murphy, W. March 28. Tools and tool-holders.-In a tool and tool-holder for lathes and other machines, the tool is cut from a bar of a uniform cross-section such as shown in Fig. 6. The tool-holder A, Fig. 1, has a swivelling clamping-bolt B, slotted to receive the tool t, and carrying a loose collar C notched to suit the upper face of the tool. The shape of the bar steel provides the tool with the necessary side clearance and side top rake, the inclination of the bolt B giving the front top rake. By turning the bolt as a whole, or simply the collar, the holder is available for tools of the opposite hand. When the tool is swivelled sideways, the diminution of front top rake is compensated for by clamping the shank A on reversible packing-pieces a, Figs. 7, 9, and 10, to cant the shank. Fig. 10 shows a circular shank suitable for screw-cutting and light work.

Patent GB-189910237-A (GB)
Title: Improvements in Calculating Machines.
Inventor: LORRAIN JAMES GRIEVE
Filed: 1899-05-15
Granted: 1900-04-14
Abstract: 10,237. Lorrain, J. G., [Goldman, H.]. May 15 Calculating-apparatus.-The apparatus is adapted for use on an account book, along a page of which it can run on rollers n<x>, n<x>. The apparatus is actuated by pressing a style l into the teeth of a chain g at a point indicated by scales at either side of the apparatus, and moving the style till it strikes the roller s<1>. There is, of course, a separate chain for each denomination, and the denominations may be distinguished by colours. To allow of both addition and subtraction being performed, the two scales at the sides are marked <0>9, <1>8, ... <9>0, and 9<1>, 8<2> ... 0<10> respectively. A cross-bar, adjustable over the chains at rightangles to them, limits the movement of the style when, as in multiplication, the same movement has to be made repeatedly. Graduated shutters, parallel to and over the chains, may be so adjusted as to cover one or more chains and divide the machine into two or more separate machines ; these are used for such calculations as are required by the English currency. The aperture or slot through which the results are read is also fitted with a sliding shutter t<1>, and a sliding pointer u for use as the decimal point. The results are shown by ten-toothed numbering-wheels e on the sloping faces e<2> of which the numbers 0 to 9 are marked. These wheels are normally out of engagement with the chains g, but the pressure of the style acts, through the levers j, k, to throw the chain forward at the end as shown in the Figure, slack being taken up and the parts restored to normal position when the style is removed, by the springs m, m<1>. Over-driving is prevented by the engagement, in normal position, of teeth on the chain between the stops s', s and s<1>, s<3>, and by the lever k entering a notch in one of the two chain-wheels h, h. The mechanism for each denomination is separated from the next by a partition. Counting-apparatus.-For the purpose of "carry- "ing " and "zeroizing," the following arrangements are provided:-Each wheel e, Fig. 15, is recessed on one side to form a space bounded by inturned teeth e<3>, and on the other to form a circular depression in which are pivoted the spring pawls q, r. The partitions are cut away so as to form a camshaped aperture round which the projection q<1> on the pawl q travels. At each rotation of any wheel e the cam allows the projection q<1> to engage a tooth e' of the next wheel and advance it one tooth-space, after which the pawl is again withdrawn. The pawls r are for engagement with single-toothed cams p which, on turning an external button on the spindle d, pick up all the pawls and push the numbering - wheels to zero ; a spring catch then arrests the turn-button.

Abstract: 23,503. Welty, M. R., and Rumbaugh, G. S. Nov. 24. Surfacing and polishing.-A machine is devised for grinding and polishing both sides of plate glass simultaneously, arrangements being made for facilitating access to the grinding-wheels for repairs &c. Figs. 1 and 3 show respectively front and end views of the machine, and Fig. 4 a detail. From the countershaft 2, the pair of shafts 5 which carry the grinding-discs 9, 9 are driven in opposite directions. These shafts 2 are carried upon swinging hangers 10 spaced apart by frames 11. Oscillatory movement is imparted to the frames through cranks 13 and links 14, the cranks being slowly rotated by the pulley 15. When it is required to move a grinding-wheel outward, the set-screw 18, Fig. 4, is rotated so that the stirrup 20 engages with the collar 21 on the shaft 5 which carries the wheel, the set-screw passing through the bracket 17 at the side of the machine. When the wheel is in position, it is pressed against the plate glass by means of the coiled spring 20. The glass is carried in a light frame 25, against which the stand and roller d is placed. The abrading- materials, such as sand and water, are fed from the hopper 27.

Title: Improvements in or relating to the Manufacture of Soap.
Inventor: MERRY ALFRED
Filed: 1900-02-06
Granted: 1901-05-06
Abstract: 2372. Merry, A., and Noble, J. H. Feb. 6. Chlorine is prepared as a bye-product in the manufacture of soap by electrolysis. Within a vessel K, containing an emulsion of oil, fat, or other saponifiable material, is placed a porous vessel D surrounded by a wire network C connected up to form a cathode. The vessel encloses a carbon anode A. The porous vessel is charged with brine from a tank L through a tube B, which may lead to the interior of the tubular anode. When in operation, the alkali which forms on the wire netting combines with the fat &c. and forms a soap which can be prepared for sale in the usual way. The evolved chlorine is directed by glass or like louvres E towards the anode, and escapes up the tube F along with the exhausted brine. The cell is covered by an impervious top H. In a modification, the cell is suspended above a soap boiler, and the alkali as it forms is washed down into the fat &c. below. In another modification, mercury forms the cathode, and the amalgam formed circulates between the cell and an emulsion of fat or oil and steam. The Provisional Specification describes another modification, in which the anode is surrounded in succession by the electrolyte, a porous cell, an emulsion of grease and water, and a metallic plate cathode, or the soap pan itself.

Title: Improvements in Batting and Compressing Cotton.
Inventor: MILLS BENJAMIN JOSEPH BARNARD
Filed: 1900-02-26
Granted: 1900-05-05
Abstract: 3737. Mills, B. J. B., [Mallett Cotton Ginners Compress Co.]. Feb. 26. Baling-presses.-Cotton is formed into a bat before compression and is folded into layers as it enters the press. For this purpose it is delivered from the gin into a box 2, whence it is fed by travelling bands 3 and 5 to a hopper 8 past the beaters 9 and 7. Feedrollers 22, 22<a> deliver it to a sinuous passage between two bands 34, 35, which are guided around rollers 27 ... 33, from which it emerges in the form of a bat a. The bat falls in a bight between the crank-actuated follower 50 and the hydraulicallyactuated one 51. As each bight, making two layers, is formed, the follower 50 presses it against the layers previously formed, the follower 51 moving back as the bale increases in thickness and the pressure in the cylinder 59 becomes too great for the safety-valve 65. Cam-operated laterallymoving fingers 79 retain the layers as they are formed during the withdrawal of the follower 50. Canvas covers are inserted in the press before the cotton is introduced, and while the ties are being secured the follower 50 is held against the bale by a strut. The box 52 is moved longitudinally by hydraulic pressure to enable the bale to be removed.

Title: Improvements relating to Friction Clutches.
Inventor: CAMPBELL MALCOLM
Filed: 1901-11-19
Granted: 1902-01-16
Abstract: 23,393. Campbell, M. Nov. 19. Clutches.-The friction shoes 15, 16 are forced into contact with the shell 12, secured on the driving-shaft, by means of levers 20. These levers are pivoted between forked arms 17 on one shoe, and bear by means of their curved ends on the other ; at their opposite ends the levers bear upon nuts 21 fitted in the forked arms 17 and threaded upon a screwed rod which carries a pinion 24 and is supported in brackets formed on the driven member 14 of the clutch. A scroll wheel 25 is fitted loose on the boss of the part 14, to gear with the pinion 24, and carries a disc 27, to which it is connected by a feather and groove ; the periphery of this disc is toothed, and the edge of the shell is notched to correspond, so that, when the disc is moved inwards, to the position shown in Fig. 3, it rotates with the shell, and carries the scroll wheel round with it, and thus causes the rotation of the screw until the two parts of the clutch rotate together. The clutch is disconnected by moving the disc 27 out of engagement with the shell and applying a brake to it In a modification, the scroll wheel is locked to the shell by radial sliding bolts connected to the operating-sleeve by links. In another arrangement, the two parts are coupled by a ratchet clutch consisting of cam surfaces on the periphery of the scroll wheel, between which and the shell are interposed rollers mounted on a loose disc ; this disc is caused to rotate by advancing a spindle with two friction discs. one of which bears on the shell and the other on the edge of the disc.
