FEED APPLIANCE FOR TYPE-SETTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 430,624, dated June 24, 1890- Application filed October 10, 1889- Serial No. 326,565. (No model.)

To all whom it may concern:

Be it known that we, RICHARD CLAY and J OHN'EBENEZER MAROHANT, citizens of En gland, residing, respectively, at Bread Street Hill, city of London, England, and at Apsley Engineering Works, I-Iemel Hempstead, county of Hertford, England, have invented a new and useful Feed Appliance for Type Setting Machines, of which the following is a specification.

In the specification of the United States Patent No. 362,751, dated May 10, 1887, is described a type-setting machine so arranged that successive types fed by hand in any attitudes into a funnel are by means of mechanism turned into the proper attitudes for printing and are collected in rows to constitute a form. The machine described in that specification was arranged to act intermittently, being put in motion by the action of a clutch operated electro-magnetically by the descent of each type from the funnel.

The present invention relates to an appliance to a machine of this kind so arranged as to dispense entirely with the electro-magnetic clutch apparatus and to permit the machine to go on working continuously whether types are fed into the funnel or not. For this purpose we arrange under the mouth of the funnel an endless band of leather or such like flexible material caused to travel continuously at a rate suited to the movement of the type-setting machine. By this band the types, when they descend from the funnel, are carried along a sloping way, which is provided with two successive stops, that are worked from the machine, being caused to reciprocate in line with the reciprocating parts of the machine. The first of these stops moves out of the way to let one type pass as it is carried along by the band, but closes against passage of a second type, and the sec- 0nd stop is then moved at the right time to allow the type that has passed the first stop to be fed into that part of the machine where it is first laid hold of by the working parts which serve to rectify its position and attitude. Should the types be fed into the funnel too slowly, no harm is done, as the machine in that case makes a stroke or several strokes without having a type to operate on. If the types are at times fed too quickly, the number in excess are merely held back by the first stop subject to the friction of the traveling band tending to advance them, and are delivered one by one to be operated on.

Figure 1 of the accompanying draw ngs is a plan, and Fig. 2 is a longitudinal SGClJlOD, of feeding apparatus according to our invention as applied to a type-setting machine such as is described in the specification of United States Patent No. 562,751, above referred to.

A is an inclined frame having mounted near its ends two pulleys B 13, around which passes an endless band C of leather. One of the pulleys B is driven by a band or other gearing from any convenient rotating part of the typesetting machine at such speed that the band travels the length of a type 1n less time than is occupied by a complete stroke of any of the reciprocating parts of the machine.

The feeding appliance is shown in Fig. 1 in its position relatively to the main cam O of the type-setting machine shown in F g. 7 of the drawings accompanying the spec1fication above referred to.

D is the funnel down which the compos tor drops successive types regardless of their attitude, whether sidewise or endwise. These types in descending from the funnel D pass through a lateral hole and guide d, and, lodging on the traveling band C, are carried by it along the slope toward the end channel H, which they successively descend to be received by the reciprocating parts of the setting-machine.

In order to prevent more than one type being fed at a time and to prevent a succession of types being fed faster than the setting-machine can receive them, the inclined guide along which the types are carried by the band C is provided with two stops, which are arranged as follows: One of the stops E is cam-shaped, fitted to turn on a stationary vertical pin e and urged by a spring 6 in such a direction that its rounded projecting edge is made to bear against the vertical side of the inclined guide A, in which position it stops a type from passing it, either closing the passage in front of a type or pressing a type that has partly passed against the side wall of the guide with the yielding pressure given by the spring 6', which allows it to press types of various thicknesses. On the upper part of the same pin 6 is fitted to turn a lever F, which is urged bya stronger spring f, so that the curved end of the lever F bears against the crank-pin 19 of the setting-machine. The crank-pin 19 by its revolution moves the lever F to the right in opposition to the spring f, which causes the lever to return to the left. 011 the cam-stop E there is a pin f, which stands up in the way of a prolongation f of the lever F as that lever is completing its stroke to the left subject to the action of the spring f. When the lever F makes its stroke to the left, its backward prolongation f meeting the pin f, causes the cam-stop E to move in opposition to the lower spring e away from the side'of the guide, thus releasing the type that may have been held back by the cam-stop and allowing it to be carried onward by the band 0. As the type thus advances it is again stopped by the downwardly-bent end g of a lever G, the other end g of which is pressed upward bya blade-spring g The end g of the lever G is sloped upward and comes immediately under the prolongation f 2 of the lever F. When the lever F is moved Patent Agent, 28 Southampton Buildings,

to the right by the crank-pin 19 of the settingmachine, its prolonged end f movingalong the incline g, presses g down, and conse quently ra ses the bent end g of the lever G, 1

allowing the type to pass and to descend the channel H. This lifting of the stop g being effected by the action of the lever F at a certain point in the revolution of the crank-pin 19 is timed so as to let the type descend at the right moment to be operated on by the setting-machine. As the lifting of the stop g occurs only when the cam-stop E is in position to arrest the type, and as the space between the two stops is only a little greater than the length of a type, no more than one type at a time can descend the channel H, and that one type can descend only at the moment when the moving parts of the settingmachine are in position to receive it.

Having thus described the nature of our invention and the best means we know for carrying the same into practical effect, we.
