Title: Improvements in and relating to sheet feeding mechanisms
IPC: B65H1/22
Filed: 1937-06-22
Abstract: 492,920. Feeding sheets. STAUDE, E. G. June 22, 1937, No. 17385. [Class 100 (i)] A sheet-feeding mechanism which is especially applicable for feeding printed blanks to machines for making envelopes for seeds is constructed with means, conformable to the packed condition of the sheets, for advancing the blanks 53 along a hopper with adjustable sides 69, 70, Fig. 9, comprising a feed band 7 which ceases to operate when the stack of blanks has reached the proper contacting angle against the friction feed wheel 32. The movement of the band 7 is preferably controlled by a feeler device which takes the form of a ratchet wheel 43, Fig. 2, mounted in an arm 41 adjustably secured to an arm 40 carried by a shaft 39 mounted in oscillating arms 24. Fig. 7, connected by a link 25 and an adjustable sleeve 26 to a threaded rod 27 which is reciprocated by a pair of relatively adjustable eccentrics 29, 30 imparting a variable throw to the arms 24 and also to a connected arm 20 freely mounted on the shaft of a ratchet wheel 34 on the shaft of a wheel 12 for advancing the band 7. The operative pawl 35 for advancing the ratchet is provided with a pin 37 engaged by a controlling member 38 on the shaft 39, and when the sheets are sufficiently advanced the pawl 35 is put out of action. The ratchet 43 is restrained by a locking pawl and ratchet from movement other than clockwise, and as it moves downwards it buckles the top sheets slightly and facilitates the separation of the sheets by the wheel 32 which is fitted with friction studs to aid the separation. The feeler device may take the form of a roller 99, Fig. 9, mounted similarly to the ratchet wheel 43, but arranged close to the roller 32. The shaft of the control member 99 may be balanced. by a counterweight. The roller 99 may be arranged above the space between a pair of axially separated rolls 32, when two rolls 32 replace the single roll shown. To prevent double feed the underside of the separated sheet is acted upon by an adjustably mounted plate 55, or by a friction roller 114, Fig. 9, which rotates in such direction that its upper surface moves contrary to the direction of feed. The front sheets of the pile are registered by reciprocating jogging devices 82, 95, Fig. 9, which are moved in opposite directions by lever mechanism 88, 90 from the eccentric mechanism which operates the advance of the pile. A single jogging device may be employed. The wheels 32 may be covered with rubber tyres instead of being provided with studs 54, and the separated blank is advanced to a glueing and folding machine by means of studs 66 on chains 55.

Title: Improvements in or relating to apparatus for treatment of the body with sprayed applications and the like
IPC: E03C1/06
Filed: 1931-06-18
Abstract: 380,831. Spray-baths. FRANK, P., 121, Nieuwe Parklaan, Scheveningen, Holland. June 18, 1931, No. 17677. Addition to 352,046. [Class 26.] In apparatus for the treatment of the human body according to the parent Specification, the carrier 9 for the treatment apparatus is reciprocated along a guide rod 10 by an endless chain 8 having a balance weight 11 and driven by a non-reversible electric motor 2 through electromagnetic couplings 25, 26. Reversal of the direction of movement of the carrier is secured by a reversing switch 30 actuated by reversing members 31, 32, the position of which is adjustable by endless chains 37, 38. The carrier may also be stopped at any desired height, being held in position by an electric brake 39 coacting with a disc 24. A number of atomizing devices in the carrier are supplied with compressed air from a compressor 87 and branch pipes 17, each atomizer having a control valve 18 so that it may be used separately. The control valve in the closed position may also switch off the current to the motor 12 driving the compressor. Automatic closing of the atomizing devices may be secured by an arrangement shown in Fig. 6 wherein the control valves are closed by levers 47 actuated by tappets 48 attached to the rod of a piston 50. When the compressed air, entering by pipe 53, is shut off, e.g. by a hand switch, the piston 50 is moved to the closed position shown by a spring 52. The piston 50 is moved to the left against the spring by the compressed air, thus allowing the control valves to be opened. A single motor may be used to drive the compressor and the carrier, a safety valve O acting when the compressed air is not used, or the carrier may be driven by a reversible motor. The drive to the carrier mav be transmitted through a mechanical coupling as shown in Fig. 16, the motor 301 driving two shafts 302, 305 in opposite directions through pinions 303, 304. The carrier is driven from chain wheels 310, 311 which rotate freely on their respective shafts and dog-clutches 306, 307 which rotate with the shafts. Engagement of one or other of the clutches is effected by a coupling link 312 oscillating round a shaft 313, movement of this shaft being caused by suitable reversing members in the track of the carrier. Positive ,engagement of one or other of the clutches is secured by a spring 324. To keep the carrier stationary while the motor 301 is running, e.g. to actuate the air compressor, both dog-clutches are retained in their central position by sleeves 329 sliding on the shafts 302, 305 and moved by a hand lever 326. This lever also operates a rod 331 which engages in one of a number of holes in disc 333 and retains the carrier in position. When a number of such appliances are installed, a single air compressor may be used with the requisite piping and control valves for each device.

Title: Improvements in liquid springs
Inventor: CUSSONS RICHARD CLEMINSON
IPC: F16F5/00
Filed: 1956-06-08
Abstract: 809,865. Liquid springs. DOWTY EQUIPMENT Ltd. June 4, 1957 [June 8, 1956], No. 17833/56. Class 108(3) In a liquid spring having three stages of resistance to compression a pressure cylinder is divided into three axially spaced chambers by centrallyapertured partitions which are traversed by an axially sliding plunger, the first chamber to be traversed including a movable spring- loaded gland ring yieldable to liquid displaced by the plunger, movement of the plunger across the second and third chambers being resisted by compression of the liquid therein. Compression of the spring by moving members 3, 33 towards each other pushes end 34 of plunger 14 across chamber A. During this movement the liquid displaced by plunger 14 causes movable gland ring 13 to yield against springs 18, 19, vent 35, allowing the air enclosed between rings 11, 13 to escape to the atmosphere. Hence the resistance during the travel a is determined by the areas of plunger 14, movable gland ring 13 and the rate of springs 18, 19. When plunger 14 enters bore 24 of partition 23 chamber A is closed from chambers B, C, and further displacement of plunger 14 through distance b is resisted by compression of the liquid filling chambers B, C. Leakage from chambers B, C, back into chamber A is inappreciable for short duration compression strokes. When plunger 14 enters bore 30 of partition 25 chamber C is isolated from chamber B and resistance is provided by compression of the liquid in chamber C alone. Since the volume of chamber C is less than the combined volumes of B, C, the load/stroke ratio will rise during displacement c.

Title: Improved lid stay
IPC: A45C13/34
Filed: 1931-06-19
Abstract: 376,927. Stays. GRAMOPHONE CO., Ltd., Hayes, Middlesex, and SEYMOUR, H. R. J., 25, Selby Road, Ealing, London. June 19, 1931, No. 17868. [Class 65 (i).] In a stay for cabinet lids, of the type in which a strut pivoted in the lid passes between and bears on two members in the box in such a manner as to load a spring as the lid is lowered, at least one of the members is carried on a spring-controlled rocking member. The distance between the bearing members is unchanged as the lid is moved, and the members may both be carried on the rocking member. The bearing members engage cam surfaces on the stay, against which they are pressed by the spring to resist the falling tendency of the lid; the stay may be provided with a recess in one edge to engage one of the bearing members to hold the lid open. The stay is shaped so that the tension of the spring is reduced in the final closing of the lid, to ensure complete closing. The bearing members may be pins, and one of them may be the pivot of the rocking member ; the pins may be provided with antifriction rollers, or with pads having sliding engagement with the stay. In the arrangement shown in Fig. 2, the bearing members 13, 17 are formed of pins carrying rollers, and the member 13 acts as a pivot for a crank 15 formed of two similar parts of sheet metal between which are the stay 4 and the rollers on the bearing members. The free ends of the crank parts are brought together for attachment to a spring 19, the other end of which is anchored to a plate carrying the pin 13, The stay 4, pivoted to the lid at 5, has a recess 9 which engages with the member 13 to hold the lid open until sufficient pressure is applied to force the stay away from the member 13 against the pressure of the spring 19. The lower edge of the stay is cut away at 11 to reduce the spring pressure when the lid is nearly closed. The other edge of the stay is shaped near the tip so that the spring pressure is reduced when the member 13 leaves the recess 9 but is increased immediately afterwards to check the fall of the lid. Fig. 4 shows an arrangement in which the rollers of the bearing members are replaced by pads 24, 23 pivoted on the pins and having sliding engagement with the stay.
