IPC: A63F1/12
Filed: 1929-07-26
Abstract: 333,044. Smith, L. July 26, 1929. Cards, shuffling.-An apparatus for shuffling a pack of cards' comprises a partition extending across a casing, to divide the pack when inserted, and symmetrically disposed above a platform adapted to support each part of the divided pack, and means for moving the two divided parts outwardly from the partition to cause the outermost cards to fall first from each divided part over an edge of the platform. The cards, on insertion at the top of the apparatus, are divided into two parts by a partition 16, Fig. 2, and are directed by a forked portion 17 to the opposite sides of two hinged flaps 18 where they come to rest on a platform 20 as indicated by broken lines in Fig. 2. The flaps are then opened by manual means such as a handle 26, Fig. 1, and links 23, 24, to thrust the lower edges of the cards off the platform whence they are guided by deflectors 13, 14 to a receptacle 15 accessible through a side opening. The links 23, 24 are of unequal lengths and cause one flap to commence its dislodgement of cards before the other. In a further modification, Fig. 4, the platform 20 is in two portions over which a flexible band 28 is stretched by means of a tension rod 30 and spring 33. By pulling down an operating rod 31 by means of a lever 34 the band is drawn outwardly across the two sections of the platform and carries the cards over the edges to fall into the collecting receptacle 15. The spring 33 returns the mechanism to the positions shown. The operating rod 31 may take the form of a roller the rotation of which actuates the band. Clockwork mechanism may be provided to actuate the apparatus.

Abstract: 828,321. Key locks. SPEGELSTEIN & SON Ltd. July 19, 1957 [Aug. 2, 1956], No. 23938/56. Class 44 A lock comprises a body, a latch member 11 slidably mounted in the body and biased so that a nose portion 10 of the latch member protrudes from the body and a tumbler element 22 slidably mounted in the body and biased into engagement with the latch member either to maintain the latch member in a locked position or to prevent it being moved into the locked position, the latch member and tumbler element each being biased by means of a coil spring 15, 22 and the direction of movement of the latch member being at right angles to the direction of movement of the tumbler element. The body comprises a base 1 surrounded by four upstanding walls 2, 3, 4 and 5 the walls 2 and 4 having Ranges 6 and 7 provided with fixing holes 8. The latch member extends through an opening 9 in the wall 5, and the coil spring 15 is positioned between the wall 3 and a recess 14 in the latch member. The latch member is guided by a pin 13 on the base 1 engaging a slot 12. The tumbler element 22 is provided with a tab 21 extending perpendicularly and which is engageable with an abutment 20 on the latch member. As shown the tab 21 is on the left hand side of the abutment 20 so that the latch member can be retracted against the pressure of the spring 15 by closing movement of the door to which the lock is secured. The engagement of the abutment 20 with the tab 21 prevents the latch member moving to its locking position in which it protrudes further from the body. The latch member can also be withdrawn from the latching position shown by means of a key 18 inserted through a keyhole in the base 1. Clockwise rotation of the key brings it into engagement with an abutment 19 on the latch member and further rotation of the key withdraws the nose of the latch member into the body. To move the latch member to its locking position the key is rotated anti-clockwise and it then initially contacts a surface 17 on the latch member and moves it to. the right; further rotation of the key causes it to engage a flange 28 on the tumbler element to raise the tumbler element against the action of the coil spring 26, when the tumbler element has been raised sufficiently to allow the abutment 20 to pass underneath the raised tab 21 the pressure of the spring 15 moves the latch member so that the projection 20 passes under the tab 21 until the movement is limited by the pin 13 engaging the end of the slot 12, the continued rotation of the key allows the tumbler element to move downwardly under the action of the spring 26 and this moves the tab 21 to a position to the right of the abutment 20 so that the latch member cannot be moved from its locking position without using the key in the reverse manner. The nose 10 may be provided either with one angled surface or with two angled surfaces in which case the door can be opened merely by pulling it.

Abstract: 789,138. Adjustable chairs. LORENZ, A. Aug. 19, 1955 [Aug. 19, 1954], No. 24017/55. Class 52(2) In a chair having an angularly adjustable back rest, a head-rest is automatically extended from the upper edge thereof as the back-rest is tilted rearwardly. As shown in Fig. 1, a motor vehicle seat 22 is mounted on a base frame 20 to the top of the rear part of which is pivoted the back rest 24 at 26. As the back rest is pivoted rearwardly, a link 32. pivoted at 30 to the back rest, lifts a lever 36 pivoted at 38 to the frame 20. A rod 42 connected to the front of lever 36 and carrying head-rest 44 is thus moved relative to the back rest in a guide loop 48 to extend the head rest. As shown in Fig. 3, rearward movement of the back rest 124, pivoted at 126 to the frame 120, lifts a lever 132 the front end of which is pivoted to the top of a link 136 pivoted at 138 to the frame and the rear end of which is pivoted to the front of rod 142 carrying the head-rest. As shown in Fig. 6, the back rest 224 is pivoted at 256 to the seat 222 carried on links 252, 258 on the frame 220. As the back rest is pivoted rearwardly, it abuts against the top of frame 220 and thus the pivot 256 is lifted and the seat 222 lifted and tilted. Also mounted on pivot 256 is a double-armed lever 232, the front of which is tied to frame 220 by a link 236 and the rear of which is connected to rod 242 carrying the head-rest 244 so that. as pivot 256 is raised, the head-rest is extended. As shown in Fig. 10, the back rest 324 and seat 322 are pivoted to the frame 320 at 326, the front of the seat being supported by a controlling lever 374 pivoted to the foot of the back rest and suspended from the frame 320 by a pivoted link 380. As the back rest is moved rearwardly the seat is raised and tilted and a leg-rest 368 is projected by lever 374. In addition a link 332 lifts a lever 336 pivoted at 338 to the frame and connected at its free end to rod 342 which extends the head-rest 344. As shown in Fig. 12, the bottom of rod 442 is connected to the front of a double-armed lever 432 pivoted at 430 to the back rest 424, the rear end of lever 432 being connected to the frame by a pivoted link 436. As shown in Fig. 1, the head-rest, when retracted, is accommodated in a recess in the upper edge of the back rest.
