IMPROVEMENT IN NUMBERING- MACHINES.

Specification forming part of Letters l atent No. 155,765, dated October 6, 1874 application filed April 13, 1874.

To all whom it may concern:

Be' it known that I, JAMES D. SMITH, of Washington, in the county of Washington and District of Columbia, have invented certain new and useful Improvements in Numbering-Machines; and I do hereby declare that the following is a full'an'd exact description thereof, reference being had to the accompan'ying drawings making a part of this application.

My invention relatesto machines for numbering bank-notes, certificates, &c., in regular order. It has for.v its object to adapt the machine to use by steam or other power; and consists in the improvements as will be hereinafter more fully set forth.

To enable those skilled to fully understand the same, I will proceed to describe the construction and operation, referring, by-letters, to the accompanying drawings, in which- Figure 1 is a side elevation of a machine embracing my invention. Fig. 2 is a rear view. Fig. 3 is a top view; Fig. 4, a similar view of the treadle and its connection with the pulley and driving-wheel; Fig. 5, a top detail view of the inking-rollers and frame; Fig. 6, detail view of rotating inking-plate; Fig. 7, a detail and section of one of thebumpers. Fig.8 is an enlarged view of the inkfountain; Fig. 9, a side view of the ordinary 'foot driving device, adapted to be substituted for the power mechanism; and Fig.- 10 is an enlarged detail view of the semi-universal jointat the rear end of the walking-beam lever.

Similar letters indicate like parts in the several views.

A is the frame of the machine, adapted to be secured at the corners to the floor in the usual manner. B is the bed or table, which is capable of adjustment throughthe medium of two slotted hangers, G G, at the front end, with thumb-screws c 0 taking in the front legs of the frame, and by a screw-rod, D, running in the upper brace at the center thereof, as fully illustrated at Figs. 1 and 2, and is old.

' E is the platen, arranged as usual. The frame Ais extended upwardly, as clearly shown at A,

Figs. 1 and 2, having a vertical slot in its forward end to guide the vertically-movin g rod F, which carries the type-arbor G. It is bifurcated to admit of the reciprocation of the arm B of the inking-carriage, and provided at H with a pivot-bearing for the walking-beam 1ever I. To the rear side of this extension of the frame is secured a bracket, J, to which is pivoted, at a, a bell-crank lever, K, of the design shown at Fig. 1, having its ends slotted, as seen. Lower down is secured a horizontal bracket, L, forming a rear guide and support for the arm of the inking-carriage, which has its forward end suitably supported within the bifurcated portion of A. The walking-beam lever I has a hanger, M, near its rear end,with a wrist'pin, b, extending into the slot in the upper end of the bell-crank lever K, and the inking-carriage arm B is provided with a similar pin, d, projecting into the slot in the lower end of said lever, so that it will be seen,in the travel of thewalkin'g-beam lever, the arm B, through the medium of the slotted bellcrank lever and pins 1) and d, is made to reciprocate horizontally to cause a proper distribution of the ink on the ink-plate N, also the type; and it will be seen that by the curved direction of' the slot in the upper end of the lever K therear end of the walking-beam lever I may continue to rise after the motion of the inking carriage arm has suspended. Suitable bumpers e fare provided to prevent any jar to the levers. The bearings of the carriage-arm are composed of anti-friction rollers. The inking-rollers are secured in a frame secured 'to the arm B. This frame is made in two parts, as it were. The rear half 1 is pivoted to the head at 3, and the forward half 2 is pivoted at 4 to the forward ends of the rear half of the frame, and may be secured in any given relation thereto by a set-screw, by which the joint may be rigid or pivotal, in order that the two parts or sections 1 2 may bear. a fixed relation to each other, or be capable of a somewhat independent vertical movement, one or both sections being under the influence of the springs g, according to circumstances, and the drop of the combined frame is regulated by the ordinary set-screws passing through the head from the rear. Springs gg, made fast at one endto the head, have their free ends pressingdownwardly upon suitable projections on the forward end of the frame back to its horizontal or normal position after it has been raised by the inclines,

as will be more fully set forth hereinafter, the whole frame swinging upon the pivot 3, and by means of the construction of the rollerframe the inking-rollers can be readily read-- justed, &c., so that they will always reach and perfectly ink the type; O O are-the inking adapted to ride upon a beveled road, 6, at the lower end of hangers P P, the object and result of which are that, as the carriage goes forward, the friction -rollers, riding up the incline,

lift the forward end of the carriage or frame, and thus, also, the inking rollers, thereby causing a more perfect inking where the type is of extensive Widths. This, however, may be dispensed with by simply removing the hangers P P, which are secured by screws for that purpose. To the rear and to one side of the carriage-head is secured a suitable bracket, Q, to which is secured a spring-pawl, j, that catches in the circular ratchet on the under side of the inking-plate, and thus rotates it a given distance on the retreat each time of the carriage. On the opposite side of the head is another pawl, k, adapted to strike the spurwheel I on the shaft of aroller, m, in an ink: fountain, n, so that at every return movement of the carriage, the roller m, which takes its supply from the fountain n, presents a new surface, against which one heel of the rear inking-roller 0 comes in contact, and from which it receives its supply to distribute. This fountain n is made adjustable on the inkingplate support, so that a greater or less area of contact between the roller 0 and the fountainroller on may be secured, and thus a greater or less quantity of ink taken up and distributed. The rear end of the walking-beam lever is connected to the pitman R by a bolt, as clearly seen on enlarged scale at Fig. 10.

I This bolt, as will be seen, is enlarged in the center, so as to present a partial sphere, which is passed into the greatest diameter of a slot in the end of the lever, and a quarter-turn given, which turns the curved surface of the bolts center within a coinciding surface in the lever, thus forming a sort of ball-and-socket joint, the bolt being retained laterally by the enlarged center, and against rotation by a feather passing in through a notch in the head into the bifurcated head of the pitman. By this connection it will be seen that the necessary vibration of the pitman in its rise and fall is compensated for. The lower. end of the pitman is connected to an adjustable wrist-pin in the crank-plate R on the rear end of the driving-shaft S, which has its rear bearing in a box mounted in a platform-bracket, T, and its forward end in a similar box mounted on a suitable cross-tie, U. An ordinary loose conepulley is arranged on the shaft S, and adapted, by a foot toggle-joint lever, to be thrown in contact with a fixed pulley, V, so that by friction the power applied to the cone-pulley is transferred to the pulley V and the shaft S, thus causing the movement of all the parts of the machine. Arranged upon thetop of the bracket T is an adjustable arm, carrying a curved friction-brake, W, which may be made to exercise any given control over the movementof the pulley V after breaking its frictional contact with'cone-pulley, so that when the foot is raised for the purpose of stopping the machine, the natural impetus which would induce to the movement of the walking beam and v the automatic change of the type is arrested by the friction-brake W. X is a heel-rest secured in proper relation to the front end of the foot-lever, and has arranged thereon a setscrew or rod, Y, which may be run up or down,

and secured in position by nuts 19 p. This screw or rod is arranged under the end of the lever, and controls the stroke or downward .movement of the end of said lever, in the end of which is arranged a roller, Z, which will rotate under the foot, and thus avoid the tendency of pushing the foot back, so that a fixed or given relation between the operatives foot and the end of the lever may be maintained. On the under side of this foot-lever, and at its forward end, isarranged a sliding bolt, of suitable thickness, adapted to be thrown forward by the operative, so that it shall come between the lower side of the lever and the top of the screw or rod Y, so that the stroke of the lever necessary to produce such friction as would induce to a movement of the machine is interdicted. The object of this arrangement is to prevent the accidental movement of the machine when not engaged in numbering, and thus preserve the proper numbers for the continuation of a series.

It will be seen that the whole power driving device may be readily removed, and the ordinary foot driving device, as shown at Fig. 9, v

substituted.

The rear anti-frictional bearing of the carriage-arm B is constructed as shown, so that the upper roller can be dropped down, to compensate for wear, by loosening the screws 7' 7', which pass through elongated slots in the side plates 8, which, with the roller that has its bearin gs therein, may be lowered and again rigidly secured in position.

I h ve'described novel construction of treadle, friction-brake, heel-rest, and semi-universal joint between the pitman and the end of the walking-beam lever as features specially adaptable and valuable in a numbering-machine, but lay no claim to them here, as I contemplate making a new application covering these features of invention, irrespective of their special application.

What I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the levers I and arm B, provided with suitable wrist-pins b d, the bell-crank lever K, constructed as described, for the purposes set forth.

2. The frame for the inkin g-rollcrs, com posed of two sections, 1 2, secured together by screwpivots 4, and to the head of the carriage, in

combination with the springs g, substantially as and for the purposes set forth.

3. In combination with the inking-frame,

' constructed as described, the inclined ways i on hangers P; to throw up the forward roller, that it may follow the upward movement of the arbor G, as and for the purposes described.

4. In combination with the reciprocating arm 13 of a numbering-machine, the adjustable anti-friction bearings s 1', whereby theplane in which the inking-carriage is moved maybe
