Record cards are passed in succession through a statistical machine by a number of feed rollers each having annular grooves 59, Fig. 7, in its surface and suction conduits 62 extending tangentially to the roller surface into each groove so as to hold the cards in frictional contact with the roller. The cards are separated one by one from a stack in magazine 15, Fig. 2, by roller 31 rotating in an anticlockwise direction and passed through the sensing station 54 to the next roller 32 which forwards it to a stacking roller 33 rotating in the opposite direction and adapted to stack the cards in magazine 19. All these rollers are driven by belt and pulley mechanism from a driving motor. Each roller has four suction conduits 62, 65, 70 disposed in circumferential grooves thereof as shown in Fig. 7. An over hanging annular shoulder is provided at the upper end of each roller to guide the cards in their movement. The suction conduits have orifices 63 at the point of contact between the roller and card and the groups of conduits for the different rollers project from manifolds 61, 64, 69 (Fig. 2) The cards are guided past roller 32 by a plate 68 and are braked in their movement past the stacking roller 33 by additional suction orifices 73 formed in conduits 70. These reduce the velocity of the card as it enters the stacking magazine 19. A movable card gate 57 operable by solenoid 58 is adapted to control the rate of feeding of cards. This matter forms the subject-matter of Divisional Specification 794,096.

Title: Improvements relating to stapling mechanism for brush making machines
IPC: A46D3/04
Filed: 1921-12-06
Abstract: 194,242. Fisher, C. E. Dec. 6, 1921. Stapling.-A brush-making machine is provided with stapling mechanism comprising a vice carried by an horizontally-reciprocating slde 168, Fig. 4, and consisting of an upper jaw v<1> fixed to the slide and a lower pivoted jaw v. The upper jaw is provided with a notch 170 for receiving the wire from which the staples are formed. The lower jaw is pivoted at 169 to the slide and is connected to a spring 177 which tends to keep the jaws closed. On the side of the lower jaw is arranged a metal strip 179 having a notch 179<a> adapted to be engaged by a dog 180 pivoted to a bracket 171 and normally held vertically by a spring 182 against a stop 184. The staple-forming wire is fed into position to be gripped by the vice when the slide 168 is in its rearmost position, whereupon a length sufficient to form a staple is severed, the vice thereafter moving forward to carry the length into position to be acted upon by the staple forming and driving mechanism. During the forward movement the dog 180 moves into engagement with the notch 179<a>. The wire is bent over the lower jaw to form a staple by the descent of a pair of grooved vertically-movable staple guides 122. Continued pressure on this jaw causes the rear end to be thrown upwards releasing the dog 180. The vice now recedes leaving the staple in the guides, the jaws being kept open until the strip 179 moves past the dog whereupon the spring 177 causes the jaws to close upon a new length of wire which has been fed forward. The slide 168 is reciprocated by means of a lever pivoted to a fixed bracket and connected at one end, by a link, to the slide, the other end carrying a spring- pressed roller engaged by a cam wheel on a rotating shaft. The wire for forming the staples is carried upon a reel and leads therefrom to a pair of rollers 145. 146, Fig. 3, the former being spring-pressed towards the latter. The rollers are intermittently rotated by means of an eccentric 149 mounted on a rotating shaft 7 and carrying an eccentric strap 150 which is connected to a lever 152 carrying a spring-pressed pawl 153 for engagement with a ratchet wheel 154 coaxial with the roller 146. The shaft 7 has mounted thereon an eccentric 167 carrying an eccentric strap 166 by means of which a plunger 161a is reciprocated vertically in a bearing 162. This plunger is formed at its lower end with a a cutter 161, Fig. 10, which co-operates, to sever a length of wire, with a bevelled edge on a guide block 156, through a groove in which the wire s<2> is fed by the rollers 145, 146. The cutter and the rollers are adapted to operate alternately.
