CHARLES WILLIAM CUTTER, OF DENVER, COLORADO.

PENCIL-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 664,726, dated December 25, 1900.

Application filed March 30, 1900. Serial No- 10,823. (No modeLl T (tZZ whom, it may concern.-

Beit known that I, CHARLES WILLIAM CUT- TER, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Pencil- Printing Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

My invention relates to a machine for printing letters and words on wooden lead-pencils for advertising purposes; and the objects of my invention are to produce a hand-operating machine that will print a pencil and then antomatically eject it from the machine; also, to provide a simple, cheap, compact, and dn rable hand pencil-printin g machine. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a plan view of my hand pencilprinting machine. Fig. 2 is a longitudinal section of Fig. l on line A. Fig. 3 is a crosssection of Figs. 1 and 2 on line B. Fig. i is a rear end elevation. Fig. 5 is a fragment of the type holding and impression block, and

Fig. 6 is a side view of a lead-pencil with letters and Words printed on it.

Similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawings, the numeral 1 designates the base of the machine. It is composed, preferably, of a block of wood. A channel 2 is formed in it. This channel has a Hat bottom and vertical sides. A step 3 is formed in each corner of the channel, the top of which is a little above the bottom of the channel. In the top of the base, between the sides of the block, a recess A is formed and through each side of the block slots 5 and 6, which form a bearing for the shaft 7 of the ink-roller 8. A recess 9 is cut across the base, in which the pencils are placed. This recess has two flat table portions 10 and 11. The lead-pencil 12 is first placed on the table 10 and is then moved on the table 11 and against the side 13 of the recess. On both sides of the base springs 14 and 15 are secured at one the recess 10 and are bent at their ends into curves 16 and 17, which fit over the lead-pew cil and hold it firmly at right angles to the line of travel of the printing-block 18, but at the same time free enough to allow it to roll along the table portion 11 of the recess under the moving pressure of the printing-block. At each end of the base I place

vertical stoppins

18 and 19, which define the stroke of the printing-block. The printing-block 18 rests and slides on the steps 3, which extend the whole length of the channel. A handle 19 is formed on its top or its bottom. Aslightlycurved recess 20 is formed at a point to rest over the ink-roller when the printing-block is at the forward end of the stroke. This recess is large enough to leave a clear space above the ink-roller, so that when the printing-block stops the rotative motion of the inkroller will continue, and thus bring fresh portions of the ink-roller in contact with the printing-type. Asquare recess 21 is made on the bottom of the printing-block at a point over the ink-roller when the printing-block is at the end of its back stroke, and against its rear pins in this recess the type 22 are placed, with their letters in the path of the ink-roller and their opposite ends against the bottom of the recess. The type are keyed in place, preferably, by a block 23, which is placed between them and the forward wall of the recess, in which there are formed slots 24. Holes 25 extend from these slots to the forward end 26 of the printing-block. In each of theslots a nut 27 fits loosely, and a capscrew 28 is extended through the holes and threaded to the nuts and extends through them and is screwed against the block and presses the block and type against the opposite wall of their recess, thus holding them in their recess. A strip of leather 29 or other suitable material, which I term an ink-pad, is secured on the under side of the printingblock and extends from the type-recess to a little beyond the curved recess 20. The ink is placed on this strip and is distributed by it evenly over the surface of the ink-roller.

. At the forward end of the base-block apenoil-ejector is placed. This pencil-ejector comprises a thin strip of metal 30, pivotally secured intermediately of its ends by a screw 31 to the top end of one of the sides of the base. One end 32 of this ejector extends toward the ink-roller and is turned at right angles to the flat central portion, that is pivoted to the base and is broadened out and extends below and also above the central portion. The depending portion registers opposite the pencils and also acts as a gage to define the position of the pencils, which are moved against it when they are put into the machine. The opposite end of the ejector is curved into a hook member 33, that extends into the central portion of the base and in the path of the printing-block. A notch 34 is made in its edge, and a pin 35 is secured in the base in the notch in a position to define the rocking movement of the ejector on its pivotal point. A stop-pin 19 is also secured in the channel of the base, which stops the forward stroke of the printingblock at a point that will give the ejector only its full stroke when the block strikes it.

The operation is as follows: A pencil is placed in the recess 9 under the curve of the pencil-holding springs. Type is then selected to print any words desired-for example, Charles William Cutter. These type are securedin the recess of the printing-block by the screw 28 and block 23. The ink-pad is then inked. The operator grasps the printing-block by its handle and bearing down hard on it gives it a very quick push forward against the forward stop-pin. The printing-block bears hard on the pencil, which rolls on the table 11 out from under the springs and drops onto the table portion 10, and as the type pass over it they impress their characters in its wood, as shown in Fig. 6, as the pencil rotates a full revolution before it drops onto the table 13. As the printing-block is moved very quick, it strikes the hooked end of the ejector with considerable force and moves the ejector into the position shown by the dotted lines, which throws its opposite end against the pencil with sufficient force to throw the pencils a foot or two out of the base of the machine.

About two thousand pencils can be printed by hand in an hour by this machine with great rapidity and are printed and ejected au- 7 tomatically.

lever secured to said base and arranged to be I engaged atone end by said printing-block at the end of its printing stroke and to strike said pencils with its opposite end, substantially as described.

2. In a pencil-printing machine, the combination of a suitable base, a recess in said base, a suitable in k-roller rotatably mounted in said recess, a channelin said base, a printing-block arranged to slide in said channel, means for defining the movement of said printing-block,

holding springs and the stop-pins, with the V printing-block, the type-recess, the nuts and screws for holding type in said recess, the ink-distributing pad on the bottom of said printing-block and the pencil-ejector, substantially as described.

4. In a pencil-printing machine, the combination of a suitable base, the in k-roller mounted in said base, a station at which pencils are placed in said base, springs arranged to hold said pencils in operative printing relation, a printing-block adapted to reciprocate in said base, an ink-pad in the bottom of said block, a clearance-recess in said ink-pads for said ink-rolls at the end of the printing-blocks stroke, means for secu ring type in said blocks in operative relation to said ink-roller and said pencils, means for defining the printing stroke of said printing-block in said base, a lever pivoted intermediate of its ends to said base, having one end adapted to be struck by the printing-block at the end of its printing stroke and its opposite end arranged to strike the pencils and eject them from the machine, a slot in said lever and a pin in said slot arranged to define the movement of said lever, substantially as described.

5. In a pencil-printing machine the combination of a suitable base, an ink-roller rotatably mounted in said base, a pencil-station in said base, springs arranged to hold pencils at said station, a printing-block reciprocally V mounted in said base, a pushhandle on said printing-block, pins at each end of said base arranged to define the movement of said printing-block, a type-receiving recess in said tached to said printing-block, the stop-pins in said base, with the pencil-slot, the pencil- I 5 holding springs adapted to hold pencils in said slot, and the automatic pencil-ejector adapted to discharge pencils from said machine, substantially as described.

In testimony whereof I affix my signature 20 in presence of two witnesses.
