KÍRBER April 16, 1962 [March 23, 1961; April 24, 1961; Sept. 18, 1961; Nov. 9, 1961; Aug. 14, 1961], Nos. 12712/61, 14708/61, 33415/61, 40146/61, and 12707/62. Headings B8A and B8C. Cigarettes are fed by an endless belt conveyer 208 into position beneath a suction head 201 (Fig. 21, not shown) which lifts the cigarettes into engagement with its lower face, a pusher member 216 then engaging the ends of the cigarettes of the row and displacing the complete row into position upon a previous row in a container 210. The pusher 216 comprises a support portion 216 which moves into position beneath the cigarette while the pusher member proper is held stationary by the action of friction grip springs on a fixed pin 218. When a stop 226 of the member 216 picks up a stop 225 of the pusher 224 the latter moves forward with the continuing movement of the member 216 and engages the ends of the cigarettes to push them forward into position above the previous row in the container 210 (Fig. 22, not shown). The head 215 which imparts movement to the member 216 has mounted in it slidably a sleeve 244 having end stops 248, 249. Slidably mounted within the sleeve 244 is a rod 236 normally urged to the right by a spring 236. At its other end the rod 229 carries a member 232 which mounts an upper guide 234 for the row of cigarettes and a stop 233 which backs up against the previously deposited row to maintain these in position. On retraction of the member 216 the pusher 224 is again held in position for the time being by the action of the springs on the pin 218 and thus acts to strip the row and leave it deposited on the previous row in the container 210. The member 232 is retracted by the action of the spring 236 and the rest of the parts resume their original positions. In (Fig. 8), a row of cigarettes C (only one visible in the Figure) is engaged by a pusher 123 and deflected into a container (not shown). The pusher 123 is associated with a support member 122. The member 122 is initially moved towards the cigarettes, the pusher 123 being held by the action of friction grip members 127. When due to relative movement between the member 122 and the pusher 123 a pin 124 reaches the end of a slot 122 in the member 121, the pusher 123 is positively deflected against the action of the friction members 127 and moves into engagement with the ends of the cigarettes C. Continued movement brings the cigarettes into position over the previous row in the container 115. On the return movement of the member 121 the pusher 123 is held by the friction members 127 and acts to hold the cigarettes from return movement during the retraction of the support member 121. A further modification is described which is identical with that described with reference to Figs. 5-10 of Specification 1,024,784.

Title: Improvements in and relating to sanding devices for mine locomotives
IPC: B61C15/10
Filed: 1924-05-26
Abstract: 225,465. Adams, E., and McAnulty, A. H. May 26, 1924. Sand, distributing on wheel tracks.-A sanding device for mine locomotives comprises a sandstorage chamber, a sand hopper or hoppers 13 in communication therewith and having or each having an outlet 16, and means for supplying air under pressure to the storage chamber to effect delivery of sand therefrom to the hopper or hoppers 13. The locomotive 1 carries sand-storage chambers 10, 34, 34a communicating with one another at the top by pipes 44, 45, 46; the two end chambers 10 and the central chamber 34<a> communicate by means of pipes 42, 43 and 41 respectively with an air compressor 6. The sand chambers, Fig. 4, are filled through openings 11 closed by screwed caps 12 and the sand hoppers have a lid 17 secured by a bolt 20 working in a spring 19. The two end chambers 10 are extended laterally to form hoppers 13 which overhang, and communicate with, the wheels 3 by pipes 16 through which sand is conveyed to the rails. Adjacent chambers are in communication by means of short nipples 38, Fig. 4, placed near the bottom of each chamber, through which sand is blown from one chamber to the other when compressed air is admitted to the surface of the sand in one of the chambers, the sand eventually being blown from the chamber 10 through the orifice 15 to the sand hopper 13 and thence to the sand pipe 16. The sand outlet to the pipe 16 in each chamber 13 is closed by a rotary valve 24 fixed to a vertical spindle 23 which is operated by a solenoid 49 through a link 51 and crank arm 25, the two valves in opposite chambers 13 being connected together by a transverse bar 26. The two solenoids on one side of the vehicle are in circuit with the trolley wire through pedal switches such as 32, Fig. 1, operated by foot pedals 33, and the trolley pole 8, Fig. 2, so that the discharge of sand to the front and rear wheels is controlled' independently. A storage battery 47 supplies current by a switch 57 to two solenoids on theopposite side of the vehicle so that in the event of a failure of the main current the sand valves. may still be operated.
