GEORGE VINING, OF HARTFORD, CONNECTICUT, ASSIGNOR TO THOMAS M. PARKER, OF SAME PLACE.

PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 474,108, dated May 3, 1892. Application n'led October 20, 1890- Serial No. 368,661. (No model.)

To LZZ whom, t may concern,.-

Be it known that I, GEORGE VINING, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Printing-Machines, of which the following is a full,clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of my invention is to provide a 1o device by means of which a plain surface may be marked with letters or any other series of characters that are to be printed from a typewheel; and my invention consists in details of the several parts making up the device as a whole and in their combination, as more particularly hereinafter described, and pointed out in the claims.

Referring` to the drawings, Figure l is a View in side elevation of my improved markzo ing-machine with parts cut away to show construction. Fig. 2 is a top plan view of the same. Fig. 3 is a view in rear elevation of the same. Fig. 4 is a detail face view of the guide-block on enlarged scale.

In the accompanying drawings the lettera denotes the main frame of the machine, that is of U shape in plan view and has an arched part a', connecting the side parts about central from themarking-wheel b. The frame a is supported on the side wheels c o', and a third wheel d is pivotally connected to the rear of the frame in such manner as to form a guide or steering wheel, a set-screw d', lo-

cated in a threaded socket in the pintlesocket, serving as a means for setting the wheel at any desired angle, so that it will control the direction of forward movement of the frame when the latter is moved along on its supporting-wheels. Vithin the main frame 4o a is aswinging frame e, connected to the main frame near the rear end by the pivots ff', and the marking-wheel b is pivotallysupported in this swinging frame e. The periphery of the marking-wheel has a number of dovetailed sockets in which the removable printing blocks or typesg are secured. The swinging frame has a limited vertical movement and is held at the upper limit of its play by means of a spring 7L, that is connected to the inner portion or frame in front of the arched part a' at its lower end and to a bracket or pron jectingarm a2 on the upright part of the main frame by means of a thumb-nut that tits upon the threaded part of a bolt secured to the spring and secured to the bracket and the thumb-nut. By means of this thumb-nut the degree of tension of the spring' may be adjusted.

On a bracket-arm e', projecting upward from the swinging frame, a socket is formed 6o for a sliding shaft ,that bears on its upper end a handle t', by means of which the shaft may be given a vertical sliding movement or may be rotated.' To this shaft is secured an indexplate 7c, that bears the letters and characters 65 conforming to those borne on the markingwheel, and the relative position of the several characters is such that when the index kZ points to a given letter or character that letter or character is one that will be printed by 7o the wheel if a downward pressure is exerted upon the handle while the index points to the said character. The lower end of the shaft bears a beveled gear-wheel that is in mesh with a gear-wheel fast to the shaft of the marking-wheel, so that by turning the handle the marking-wheel will be rotated. When it is desired to print any given character, a downward pressure upon the handle thrusts the swinging frame downward, bear- 8c ing with it the marking-wheel. Pins b', projecting laterally from the marking-wheel, engage a slotted guide-block m, that is fast to the said frame, and hold the wheel in proper position to imprint the character squarely upon the fiat surface upon which the markingwheel is placed.

As shown inthe drawings, the markingwheel is at about the lower limit of its play, one of the cutting-pins projecting through the 9o side of the marking-wheel having entered the slot in the guide-block (see Fig. 3) and serving to hold the wheel in proper position to have the imprint of the lowermost type made upon the surface to be marked.

In order to provide for a forward feeding movement of the carriage after each downward movement of the marking-wheel for the purpose of printing a letter or character, the feed device fm is employed. This consists of roo a bent lever lm', pivoted to the main frame, with one arm m2 slotted and engaging a pin fast to adownward projection from the swinging frame,while the upper arm 'm3 of the bent lever' supports the pawl o, the forward end of which engages the teeth on a ratchet-wheel p, that is secured to the shaft on which the side wheels of the frame are supported. The upward movement of the marking-wheel frame lifts the outer end of the bentlevel` and throws the upper end forward a distance sufficient to enable the pawl on the next downward movement to be retracted a distance sufcient to engage the next tooth of the ratchetwheel. i

On the front of the main frame there is supported the inking device r. This consists of an inking-Wheel r', supported in a box, with its periphery in contact with the type on the marking machine and in rubbing contact with a porous wiper r2, the bottom of the roller-box being perforated and communicating by a narrow slot with the closed ink-receptacle r3, the screw-cap of which is provided With an elastic bulb 194, by the compression of which ink is forced from the inkwell into the porous wiper that is in contact with the periphery of the inking-Wheel. The rotation of the main wheel causes the type to rotate the inking-wheel in such manner as to transfer the ink to the several type, and thus provide means for marking.

kThe type are made removable, so that a given type spelling out words or sentences may be arranged on the periphery of the wheel, and these sentences maybe by a single forward movement of the wheel while the handle t" isheld down by the operator printed upon the surface upon which the markingwheel rolls, the guide-block being thrown out of position by unclamping it and turning it out of the path of the pins that project from the sides of the marking-wheel.

I claim as my invention- 1. In combination with a wheeled frame, zu swinging frame suspended therein, a markingwheel with its periphery provided with dovetailed slots, pivoted in said'frame, the removable type with beveled edges fitting the dove-l tailed slots, whereby the type are securely held in place, the spring extending between the two frames and'operating normally to hold the periphery of the marking-wheel out of contact with the surface until the frame is placed, and the sliding plunger by means of which the swinging frame and the markingwheel are depressed, all substantially as described.

2. In combination with a wheeled frame, a swinging frame suspended therein, a markingwheel provided with dovetailed slots, pivoted in said frame, the removable type fitting said dovetailed slots, the sprin g extendingbetween the two frames and operating normally to hold the periphery of the marking-wheel out of contact with the surface on'which the frame moves, the bent lever pivoted to the main frame, having one end slotted and engaging a pin on the swinging frame and the other end bearing a swinging pawl in engagement with a ratchet-wheel secured to the side wheels, the ratchet-wheel, and the sliding plunger, by means of which the swinging frame and the m arkin g-wheel are depressed, all substantially as described.

3. An inking device for a marking-machine, consisting of an inking-wheel supported with its periphery adapted to engage the type of the marking-machine, the porous wiper engaging the periphery of the inking-Wl1eel,the perforated roller-box supporting the porous wiper, the closed ink-receptacle eommunieat-- ing by the narrow slot with the roller-box, and the screw-cap provided with an elastic bulb, whereby ink is forced from the ink-well into the porous wiper, all substantially as described.

GEORGE VINING.
