lENCIL-PRINTING MACHINE.

Specification of Letters Patent.

, Patented J une 4t, 1912.

To all whom it may concern Be it known that I, THoMAs R. OWEN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Pencil-Printing Machine, of which the following is a specification.

The main object of the present invention is to provide a manually operated machine for printing with ordinary metal type on pencils suitable marks or characters indicating, for example, the manufacturer or seller of the pencils.

Another object of the invention is to provide a manually operated machine where such printing may be effected in a rapid and economical manner.

Other objects of the invention will appear hereinafter.

In the accompanying drawings illustrating the invention: Figure 1 is a rear elevation of the improved pencil printing machine. Fig. 2 is a vertical transverse section thereof. Fig. 3 is a front elevation of the pencil printing machine partly broken away. Fig. 4: is a plan view thereof. Fig. 5 is a detail section on line m in Fig. 2.

1 designates the base of the machine provided with standards 2 extending upwardly therefrom to form the frame for supporting the various parts. A platen or pencil carrying cylinder 3 is journaled in bearings 4 on these standards, the driven shaft 5 of this cylinder being connected to be operated intermittently by a driving shaft 6 journaled in bearings 7 on the standards.

The driving shaft 6 may be operated by an operating hand-wheel or fly-wheel 9 having a handle 10, said hand-wheel being mounted on the main shaft 11 extending from one of the standards 2 and the hub of said hand-wheel being provided with a pinion 12 engaging a gear 13 on the driving shaft 6 to rotate the latter.

The intermittent driving connection be tween the driving shaft 6 and the driven shaft 5 consists of a crank ltfast on the driving shaft 6, a link or rod 15 pivoted to said crank and an arm 16 rotatably mounted on the driven shaft 5 and pivoted to the link 15, so that rotation of the crank 14: will cause oscillation of the arm 16, said arm 16 being provided with a pawl 17 engaging in notches 18 in a ratchet wheel 19 fast onthe driven shaft 5. A click or stationary pawl 20 is provided for engaging the notches l8 vjusted to proper elevation by wedges 36, 37,-said wedges being reversely' in the wheel 19 to retain the wheel and the driven shaft 5 and pencil carrying cylinder 3 in position in which they have been moved into until they are further operated by the intermittent operating means above described. Pawl l7 and click 20 are provided with springs 21, 22 for holding them in engagement with the wheel 19.

The impression means consists of a spring supported form carrier or holder 23 provided with means for holding the type or printing form and provided at each end with means for guiding it on the standards 2, said means consisting, for example, of grooves or ways 25 in the end portions of the member 23 fitting and engaging over fixed guide flanges 26 on the standards 2. Springs 27 extend between the tops of these guide flanges 26 and a lateral projection 28 from the member 23, so as to tend to hold the member 23 in elevated position, said member 23 being intermittently depressed for impression by cams 39 on the driving shaft 6, said cams engaging anti-friction rollers 30 rotatably mounted on the member 23. The printing may be eflected by a series of type indicated at 32 fitting in an elongated case or box 33 of suflicient width, for example, to hold a single line of type wit-h face of the type extending somewhat below the bottom edge of the box, a screw 34 being provided at the end of the box to engage the end of the line of type to pinch the same in place in the box and screws 35 being provided in the holder 23 to hold the case in place. The type case may be adoverlapping placed and being pressed toward one another by adjusting screws 38 provided with capstan nuts 39 for adjustment thereof. A spring 40 fastened to form holder 23 ex tends through a hole therein and engages under the lower wedge 37 to retain these wedges in position when the type case is removed.

Means are provided for feeding or supplying pencils to the cylinder 3, said means consisting, for example, of a platform or tray 41 supported on the frames 2 at the front of the machine, said platform being inclined rearwardly and downwardly toward the cylinder 3, so that the pencils will roll or slide toward and against the cylinder 3 by gravity and will lodge in recesses or longitudinal grooves 43 of the cylinder 3.

A gage stop or guide flange 4:2 is provided on platform 11 for insuring that the pencils are fed in proper position for uniform printing. Retaining guiding and pencil seating springs 4A extend over and partly around and in contact with the cylinder 3 to hold the pencils in position thereon while passing the impression position, said springs 44: being carried by an arm orbracket 45 extending from the standards 2.

The inking mechanism comprises an ink disk or plate 48 mounted by its central stud 49 in a journal bearing 50 on the bracket 45. The ink rollers 52 are journaled on a carrier or frame 53 which is pivoted on levers 5 1, pivoted to arms 55 which are carried by a rock shaft 70 journaled in the standards 2. A link 56 connects an arm 71 on said rock shaft with the crank 14 aforesaid, to cause intermittent operation of the inking rollers, and a spring 57 connects arm 55 with a tail 58 on lever 54, to tend to press the inking rollers downwardly. A guide means consisting of a deflecting plate or bar 59 supported on fixed bracket 15 is provided to engage the projecting end portions of the shafts 61 of inking rollers 52 to lift the ink rollers into contact with the type as they pass thereunder. A spring plate 63 extends rearwardly from the tail 58 of arm 54, and is provided with a hook or pawl tooth 64: to engage notched teeth 65 on the periphery of the inking disk 48, to cause rotation of the disk, one step at each movement of the inking rollers, a fixed pawl 66 being provided to engage said teeth to prevent back movement.

The operation is as follows: The pencils are placed on platform 4:1, and roll or slide thereon so that the end pencil rests against the cylinder 3. In the rotation of said cylinder, as each recess 43 comes opposite the pencils it will receive a pencil and will carry it upward and under the impression mechanism, the intermittent operation of the cylinder providing a rest at the moment when the recesses are in the pencil receiving position, to give time for insertion or reception of the pencils, the preceding recess being at this time at rest directly under the impression mechanism. At this time the impression mechanism is operated by the cam means 39 to press the type onto the pencil in said preceding recess. In the next step of the intermittent operating means 16, 19, the printed pencil will be carried to the'rear, and the next is brought to the printing position, the impression means being raised by its springs 27 and the inking rollers being moved forward to contact with and ink the type 82. The inking rollers are supplied with ink at each rearward movement, by contact with the inking disk 48 which is daubed with ink from time to time and which by its intermittent rotation in conjunction with the reciprocating movement of the inking rollers, serves also as a distributing disk. The elastic strips or springs 1 1 serve to retain the pencils in position during the movement past the printing position and particularly during the recession of the type means, said springs therefore serving as stripper means. The printed pencils are eventually discharged by gravity from the cylinder as they are carried around to the underside of the cylinder by the rotation thereof, and may be received in any suitable receptacle.

An important feature of the present invention is the use of adjustable or separate type for the printing in distinction to a die, and the adjustability of the type carrier or case is of advantage in this connection as it enables the position of the type to be adjusted for diflierent thicknesses of pencils.

hat I claim is A manually operated pencil printing machine comprising a pair of standards each having lower intermediate and upper journal bearings and a guide flange, a driven shaft mounted in the lower journal bearings, a pencil carrying cylinder having longitudinal pencil grooves and fixed to the driven shaft, a ratchet wheel fixed to the driven shaft and having notches registering with the longitudinal pencil grooves of the pencil carrying cylinder, a crank arm loosely mounted on the driven shaft and provided with a movable pawl engaging the notches of the ratchet wheel, a stationary pawl engaging the notches of the ratchet wheel, a driving shaft having a gear fixed thereto and a crank arm and mounted in the upper journal bearings, a main shaft mounted in the intermediate journal bearings, a rod connecting the crank arms, a hand-wheel having a hub provided with a pinion meshing with the gear, retaining guiding and pencil seating springs extending over and in close contactwith the pencil carrying cylinder,

means .for supplying pencils to the pencil tion, and cams fixed on the driving shaft bearing on the anti-friction rollers for clepressmg the form carrler.

In 'testnnony whereof, I have hereunto set my hand at Los Angeles, California, this 21st day of July 1909.
