Title: Improvements in fasteners for mail bags and the like
IPC: B65D77/18
Filed: 1921-03-01
Abstract: 159,827. MacDonald, A., and Wallace, T. W. March 6, 1920, [Convention date]. Strap and chain fastenings; seal fastenings; fastenings for mail-bags.-In a device for securing mail-bags and the like, two interengaging parts secured to the ends of a chain or band are arranged to have a pivotal action upon each other by wnich the band is tightened, and are then secured by a locking-piece, which is sealed in the closed position. In a modification, an arm is passed through eyelets in the top of the bag, and then secured and sealed to a second member to which it is pivoted. A reversible destination label is also secured in position when the fastening is closed. In the form shown in Figs. 1 and 5, the inner part 20 is formed with a depending hooked portion 22, with which the outer part 21 can engage in the manner shown. When folded down into the closed position, it acts to tighten the chain 39, one end of which is connected to each part of the fastening. Such connection may be permanent or adjustable, as, for instance, by the engagement of one arm of a bell-crank lever 41 with the links of the chain, in such a way that the lever is firmly secured when the fastening is closed. A stud 25 upon the member 20 passes up through an aperture into a cup or recess in the member 21, and is then engaged by folding down a locking-piece 29, which engages with a shaped face 30 of the stud 25. A reversible label 28, Fig. 1, may then be placed upon the locking member, and a soft metal sealing-pin 35 applied. To release the fastening, the end of the locking-piece is prised up by a suitable implement 44, thereby breaking the seal. Fig. 5 shows another form of label, which is placed over the stud 25 of the part 20, and secured by the part 21, or it may be provided with key-hole slots engaging with headed pins upon a plate formed on the member 20. A further means which may be adopted to secure the label consists in engaging the edge of the aperture 49, Fig. 8, in a slot 53 cut in the base of the stud 25, and holding it in that position by the engagement of a spring pin 54 with a hole 55 in the label. The fastening may be sealed by wax instead of a metal plug. Figs. 11 and 12 show a modification in which a hook portion 27<1> upon the member 21 is engaged by a ring 29' pivoted to the member 20, and arranged within a cup which can be filled with wax and impressed with a seal, thus covering the ring 29. The label in this case comprises a curved strip 66 which is engaged when in position by a cup 66<1>, and is carried bv a wire 67 which is secured between the two parts of the fastening. In Fig. 13, the parts are shown locked together bv a. fiat ring 70 which forms the label, and is sealed by a wax seal filling a cup 28, and covering a sliding pin 73, the end 72 of which projects over the face of the ring and prevents its removal. The fastener shown in Fig. 10 is adapted to be passed through eyelets in the mouth of the bag, whereupon the two parts 59, 60 are engaged and secured by a locking lever which is sealed in the manner above-described.

Title: Improvements in or relating to sheet conveying apparatus
IPC: B65H1/26
Filed: 1943-05-03
Abstract: 584,730. Sheet-conveying apparatus. STEVENS, A. H. (Miller Printing Machinery Co.). May 3, 1943, No. 6965. [Class 100 (i)] Mechanism for raising and lowering a support such as a feed or delivery table used in connection with a printing or other processing- machine for acting upon sheets is constructed with carriers 5 which can be lowered by the delivery chains of the machine and can 1e transferred directly to the pile-raising chains b4 of the feeding mechanism in order to feed the sheets again through the machine. Each carrier 5 is formed with a supporting surface 6 and four legs 7 and a full carrier can be transported by a truck engaging the under surface of the support 6 and placed between four depending chains 14 so that the carriers can be raised by the engagement of bars 16 on the chains with registering bars 16a on the supports. The piles are raised automatically during the operation of the sheet-feeding mechanism, and when one pile is exhausted the chains can be operated quickly to bring the new pile into operative position. The shafts 12 from which the chains 14 are driven are operated in synchronism by means of pawl-and-ratchet gearing comprising a wide ratchet gear 54 engageable by means of a pawl 52 on a collar 45 freely mounted on the ratchet shaft, and also engaged by a pawl 57 on a freely mounted sprocket wheel geared to the shaft of an electric motor which is energized when the pile is to be raised quickly, the pawl 52 being then put out of action by means of a handle 53. When in action the pawl 52 is operated by lever-and-link mechanism comprising a cam-oscillated lever 35 which engages a lever 38 connected by a link 49 to an arm 46 on the collar 45. When the feeder frame is moved on tracks 10 away from the machine the lever 38 moves away from the lever 35 so that the automatic raising mechanism is put out of action. This mechanism may be automatically controlled by the height of the pile in a known way. A hand-wheel 64 may be connected to either the ratchet shaft 26 or the shaft 18 so as to move the chains 14 by hand if desired. The pawls permit adjustment to raise the piles but if lowering is desired the pawl 52 must be tripped. The other pawl need not be tripped as hand-lowering of the pile merely drives the motor 59 in reverse direction without harm. The sheet-feeding mechanism forms the subject-matter of Specification 584,782.

Filed: 1945-03-20
Abstract: 594,595. Hydraulic apparatus. PAGE, H. E. March 20, 1945, No. 6992. Convention date, March 20, 1944. [Class 78(iii)] A hydraulic apparatus, in par ticular a jack, in which a work piston 11 in a main cylinder 25 is operated to execute its working stroke by pressure-generating means 36 (actuated by handle H) which forces fluid under pressure into the main cylinder, includes a spring 22 operably associated with the work piston to cause limited protractive movement thereof from the main cylinder. A compression spring 34 operable upon expansion to cause retractive movement of the work piston into its cylinder, and means operatively associated with said pressure - generating means to cause compression of said compression spring when said pressure - generating means forces fluid into the main cylinder, 25 to cause protractive movement of said work piston. Preferably rotatable valve 42 seated in bore 40, Figs. 1, 1A, distribute fluid drawn from reservoir R through port 37 by the motion of piston 36. past valve 54 and along port 58. Operating rod 44 controls valve 42 which has internal bores, 50, 51, 52, 53 and also bore 55 communicating at its inner end with longitudinal bore 56, and which has eccentric cam 62 capable of contacting stem 67a or 75a to unseatvalves 65, 67, Fig. 2, or 71, 75 respectively. With valve 42 in position as shown in. Fig. 5, oscillation of pump piston 36 produces merely a circular flow of fluid from reservoir R via port 37, valve 54, port 58, bores 55 and 56, and port 57, back to the reservoir. A twist of rod 44 moves valve 42 into the position as shown in Fig. 6 in which position fluid driven by pump passes through port 58, bore 50, bore 52, port 81, Fig. 2, from whence it divides, part to pass along port 84 to build up pressure in surge chamber 33 and port to pass valve 71 and along port 72 to build up pressure in chamber 33 and part to pass valve 71 16 and connecting-rod 26 to actuate lifting arm 8. At the same time cam 62 presses upon stem 67a to unseat valves 65, 67 and to allow the initial pressure in annular chamber 25 to be released, the fluid flowing back via port 87, valves 65 and 67, and port 57 to the reservoir, thus permitting compressed spring 22 to be released and to give an initial movement to work piston 16 so that the work may be contacted, the raising of the work being effected by hydraulic pressure. A further twist of rod 44 moves valve 42 to the position as shown in Fig. 7. Cam 62 contacting stem 75a unseats valves 71, 72 to allow fluid compressed in chamber 30 to pass to port 57 back to the reservoir. Compressed fluid in surge chamber 33 is forced by plunger 32 through port 88, bore 52, bore 53, port 80, valve 65 and port 87 to annular chamber 25 so that spring 22 is compressed and the work piston 16 retracted. Finally, employment of pump 36 may force fluid into annular chamber 25 so as to compress spring 22 further and to bring arm 8 to full down position. Specification 594,586 is referred to..
