Title: Improvements in systems of food service
IPC: G07F5/18
Filed: 1924-03-31
Abstract: 226,085. Pratt, E. D. March 31, 1924. Self-service and like means for effecting and controlling sales.-In a system of food service, duplicate checks identified with an order for food, are delivered, one to the customer on one side of a partition, the other to an attendant behind the partition. Mechanism operable from the rear of the partition indicates to the customer the delivery of his food and the compartment containing it. Fig. 1 shows a front view of the partition, and Fig. 3 a. section through a food compartment. Fig. 7 show a detail and Figs. 15 and 16 show sections through the duplicate check mechanism. A dividing partition 1 between a dining room and hitchen is formed with apertures 2 each registering with a food compartment 3 having front and rear doors. In the partition are duplicate check mechanisms. Piles of checks are placed in stacks 41, 42 and the customer drops the required number of coins, for the food ordered in a slot 33, the coins passing through a shoot 34 to a hopper 35 and thence to a shoot 57, the first coin falling on an adjustable L- shaped member 54. The pressing of a spring- controlled rod 37 operates the check mechanism, the inner end of the rod 37 pressing the topmost coin against the wall of an apertured portion of a hopper 35 so that an attached slide 36b causes a gear wheel 47 to rotate and move a slide 43 to eject a check from the stack 41 to the customer, the slide 36b pushing out a check from the stack 42 to the attendant. As the slide 36<b> moves forward, a portion 52 of a plate 50 attached to the slide and carrying the member 54, is withdrawn, permitting the coins to fall from the shoot 57. The mechanism for indicating the delivery of food comprises drops 23 controlled by magnets and operated by push buttons by the attendant. Means for indicating the compartment containing he food comprise discs marked with numerals and operated by handles. Springs co-operating with notches on the discs hold the discs in any position and a framed opening 31 in the front face plate permits the exposure of the numerals desired. The front door 8 of each food compartment is locked by a latch 17 released by the deposit of a duplicate check in a slot 9 formed at the rear of the partition by guard plates 10, 11, 12, the customer's check being guided into a notch seat 13 in a lever 14, an inward push on a plunger 15 pressing the check against the lever 14 which is rocked against the action of a flat spring to release the latch 17 when weights automatically open the door.

Title: Improvements relating to printing machines
IPC: B41F13/20
Filed: 1917-06-15
Abstract: 166,166. Mascord, G. W. June 15, 1917. Rotary machines; intaglio-plate printing; stopping and like arrangements. - In a rotary printing-machine, particularly of the kind printing from intaglio cylinders, the spindle or mandrel of the printing-cylinder or engraved shell is mounted in a spherical swivelling bearing at one end so that the cylinder may be swung clear of the impression roller and the cylinder or shell readily removed from the spindle or mandrel. The spindle or mandrel is preferably driven through a magnetic clutch, and when such clutch is employed the spindle or mandrel may be mounted on an ordinary non- spherical pivoted bearing. As shown in Fig. 1, the engraved shell a is carried by a mandrel a', the spindle b of which is mounted in a swivelling spherical bearing c at one end and is readily removable from its bearing d at the other end so that it may be swung into the position shown in dotted lines to permit removal of the shell a. The spindle b carries one part f of a magnetic clutch, the other part f<1> of which is carried by a shaft driven by gearing g. The engaging faces of the clutch parts may be circular and concentric with the axis of the bearing c or may be flat, the shaft carrying the part f<1> being movable axially to allow of the swing of the spindle b. The faces of the clutch parts may also have interengaging ribs and grooves to afford a positive drive. When the magnetic clutch is employed the bearing may be constructed as shown in Fig. 6 and consisting of a cylindrical projection c engaging a cylindrical recess c<1> in the frame. In other forms of machine, the clutch is omitted and the cylinders are driven by spur gearing arranged to permit ready disconnection to allow of the swinging movement of the spindle b upon its spherical bearing.

Abstract: 977,534. Hydraulic shock-absorbers. FLUGZEUGWERKE DRESDEN VEB. March 10, 1961, No. 8776/61. Heading F2S. In an hydraulic suspension unit, e.g. for motor vehicles a piston 17 workable in a cylin der 2 accommodates, loosely within a bore 27, a pistor valve 28 controlled by a pair of springs 24, 30 which are located respectively in ar upper chamber 10 of the cylinder 2 and in the lowel end of the bore 27 and which are arranged to open a passage through the piston 17 when the latter is above its normal centre position and the compression of the upper spring 24 exceeds the upward thrust of the lower spring 30. Radial openings 32, 31 respectively in the piston 28 and the bore 27 are brought into alignment to provide the passage through the piston 17 when, during an upward movement of the piston 17 from its centre position, the compression of the spring 24, fixed between a sealing bush 23 in an end plate 3 for the cylinder 2 and a pin 25 which extends through the piston 28 and is axially movable in a slot 26 in the piston rod 16, overcomes the upward thrust of the spring 30 and moves the piston 28 downwards. The superior force of the spring 30 maintains the piston 28 raised and the radial openings 32, 31 out of alignment over the lower half of the piston stroke. A pressure chamber 12, with an outer casing 1 and accommodating a flexible tube 13 filled with a compressible liquid, communicates with the upper and lower ends of the cylinder 2 through one-way valves 11, 15 respectively, the upper end of the cylinder 2 being connected to a reservoir 7 through a one-way valve 9 in a cover plate 4 which is tightened down by threaded ring 5. A rubber cap 6, interposed between the cover plate 4 and the ring 5 and having sealed connections with the plate 3, forms the reservoir 7.

Abstract: 653,067. Finishing pile fabrics. WILTON ROYAL CARPET FACTORY, Ltd., and CLARKE, S. H. R. March 30,1948, No. 8983. [Class 42 (i)] Patterns in relief are produced on pile fabrics (e.g. carpets or rugs) by holding stationary a fabric which has a uniform pile height and clipping away those parts of the pile which are to be in lower relief by means of clippers moved, manually or automatically, over the fabric so as to contact only those areas which are to be clipped, leaving the parts in high relief at the original height. The clipping of the pile 1 may be of constant or varying depth; it may have a straight (Fig. 1), continuously-curved (Fig. 2) or wavy (Fig. 3) profile until it ceases abruptly at the outline 2 of some figure of the motif. The pattern may be marked on the fabric prior to clipping by the impression of a templet consisting of strip metal fixed on edge to a flat wooden backing; the pile is then clipped with manually- or motor - operated mechanical clippers. Alternatively, a templet without a backing may be laid on the pile and used to guide the operator, or clippers may be arranged to follow a templet automatically.
