MACHINE FOR PRINTING PENCILS.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed July 15, 1908. Serial No. 443,715.

To all whom it may concern:

Be it known that 1, WILLIAM H. a citizen of the United States of America, and resident of Brandon, in the county of Rutland and State of Vermont, have invented certain new and useful Improvements in Machines for Printing Pencils, of which the following is a full, clear, and exact description.

This invention relates to printing and embossing machines, and more particularly to that class thereof in which certain characters may be impressed or rolled into cylindrical bodies of various kinds, such as for instance pencils, package handles, pill boxes, etc., and it has for one of its objects the provision of a machine in which the articles to be marked are contained in a hopper or reservoir from which they gravitatively descend into the impressing mechanism, and are sub sequently automatically discharged.

My invention has, furthermore, for its object the provision of improved impression devices which comprise flat surfaces between which the articles are rolled along and into engagement with a suitable die or type form.

A further object of the invention resides in the improved construction of the inking mechanism whereby ink, bronze or similar material may be deposited onto the dye or type.

Further objects of the invention will hereinafter appear, and the means for their attainment be particularized in the claims.

In the accompanying drawings, in which similar characters denote similar parts,- Figure l is a side view of a machine embodying my invention; Fig. 2 is a top view thereof; Fig. 3 illustrates a vertical section on line 33, of Fig. l, and Fig. a shows a longitudinal section on line 4.4, of Fig. 2, as seen in direction of arrow. Figs. 5 and 6 are cross sectional views on lines 55, and e e, Fig. 2.

Briefly stated, the machine comprises a vertically-disposed reservoir in which the articles to be marked are supported one above the other, and from which they descend one by one onto a receiving bed which contains the marking die. This die may be supplied with ink, bronze or similar material, and the article is forcibly rolled over said die and subsequently dropped through an aperture in the bed; while another blank article will be permitted to leave the reservoir and enter the machine, as before.

JOHNSON,

In the drawings, 10 denotes the bed of the machine supported on legs 11 and having at its rear side bearing brackets 12 in which the main shaft 18 of the machine is journaled. Rotary movement is imparted to this shaft by a clutch pulley 14 which is normally loose thereon but may be operatively connected therewith by a cone-spool 15 operable by a hand lever 16, which is fulcrumed at 17.

The shaft 13 actuates in properly timed manner a pair of mechanisms, viz.: one for bringing successive blanks into contact with the impression-device, and the other for supplying this device with ink or other suitable marking material. In the present case the machine is adapted to impress lettering upon the cylindrical surface of pencils, which are placed into a reservoir or hopper H formed of a pair of trough-like members 20 provided with guide strips 21 between which the pencil-blanks P are held endwise. Each pencil, as it issues from between the strips 21, drops into the flat-surface bed 10 (see Figs. 3 and 4) which is provided with a pocket 22 to receive a die or type form 23 which may be vertically adjusted as for instance by a thumb-screw 2a and held by a screw 25. The blank is rolled along the bed 10 by a pressure-slide or platen 26 having a fiat under-face and reciprocable in ways 27 of the bed, by an ear-bolt 28 at tached to said slide and connected through a link 29 with a lever 30, which is pivoted at 31 and carries a roller 32 acted upon by a cam 33. This cam is secured to a crossshaft 34-, journaled in bearings 35, and having at one end a bevel gear 36 engaged by a pinion 37 on the shaft 13 above mentioned.

Referring to Fig. 4:, it will be seen that the slide 26 is active in rolling a pencil P over the type form the cam 33 not yet having attained its limit of throw -moveinent, so that, as the shaft 34 is rotated in the direction of arrow a, said slide will ultimately bring the pencil P into position to drop through an aperture or slot 38 in the bed plate. Means are provided for permitting a new blank to drop into position to be rolled by the slide 26, these means being preferably controlled by the movement of the slide and connected with the hopper H in such a manner that only one blank will be fed at a time.

This mechanism comprises what may be termed a bypass slide, consisting of a separatlng or check member 40, and a holder or shelf 41, which latter is made in the shape of a yoke (see Fig. 2) and supports said member 40. The yoke is mounted for short sliding movement on extensions 42 secured to the hopper H, and it is actuated in one direction (from left to right in Fig. 4'.) by an adjustable abutment screw 4L3 (carried by a lug on the rolling-slide 26) engaging an abutment 44 secured to the underside of said yoke. As soon as this engagement takes place, the yoke is moved bodily toward the right as Fig. i is viewed, thus bringing the shelf 41 beneath the stack of pencils in the hopper, and at the same time withdrawing the separator 40 from below the lowermost blank in the hopper, so that this blank can now fall onto the shelf and into such position that the separator in its return stroke can pass below and hold the next blank in the hopper.

Inasmuch as the blanks in the hopper and above the shelf 41 can move only vertically by virtue of the confinement of their ends in the channel bars 20, it follows that a pencil on the shelf l1 will drop only after said shelf has been withdrawn from beneath it, this action being accomplished subsequently to or during the return movement of the rolling-slide 26, and by the second mechanism controlled by the main shaft 13 above stated. This second mechanism, viz.: the ink-supplying device for the die or type form 23, consists of a carriage 50 connected by a link 51 with a lever 52 which is fulcrumed at 53 and carries a roller 54 engaged by a cam 55 on a cross-shaft 56,which has a bevel gear 57 (see Figs. 1 and 3) and is journaled in bearings 58 of the frame. The gear 57 is in engagement with a pinion 59 on the main shaft 13, and the two mechanisms above described are so timed relatively to each other that they alternately co operate with the type form 23. It should be noted that the cams 33 and 55 actuate their respective levers 30 and 52 inwardly only, while a spring 60 interposed between a collar 61 on a tubular rod 62, and a collar 63 fixed on an inner rod 64, serve to hold both levers in engagement with the cams, as will be readily understood.

The slide 50 carries a pair of composition rollers 65, 66, which take ink from a disk 67 rotatably mounted in a bearing 68 and on a center-screw 69 whereby said disk may be vertically adjusted relatively to the rollers 65, 66. The disk is secured to a vertical shaft 70 which also carries a ratchet 71 which is intermittently rotated by a springretracted plunger rod 72 provided with a pawl 7 3 and pushed inward by a pin 7% on the lever 52during the final inward movement thereof.

The carriage 50 carries at one side a pin 75 adapted to engage a cam faced lever 76 which is pivoted at 77 and has an adjustable abutment screw 7 8 for pushing the by-pass yoke with the shelf 41 and detent 4-0 so as to permit a blank to drop from the pile in the hopper, said screw engaging an abut ment 79 in the yoke.

Inasmuch as the underside of the slide 26 is apt to be daubed with ink deposited on the blank by the die 23, l have provided a device whereby this ink will be wiped off from the slide, this device being preferably a roller 80 covered wlth felt or some absorbent material, and journaled in an arm or' frame 81 pivotally hung on shaft 34, which is adapted to yield to downward pressure by virtue of a spring 82 the compression of which may be varied by a nut 83 on a stationary rod 84, the latter also having a fixed collar 85 which servesas a stop to limit the upward movement of said arm.

The roller 80 is rotated by the meshing with a gear 91 thereon of a gear 86 on a stud shaft 87 also journaled in the arm 81 and having a pulley 88 which may be driven by a belt 89 from a pulley 90 secured on the shaft 3.4. above described.

The pencil rolling slide, or platen 26, is made with a portion which comprises its face that rolls over and upon the pencils yieldable so that variations in the diameters of pencils may be provided for; and the construction to this end is particularly represented in the enlarged cross section Fig. 5, in which the platen isshown as constitut d of upper and lower sections 93 and 94, the upper one having the side ribs which engage in the aforementioned groove ways 27in opposite sides of the frame. The upper section 93 has spring receiving sockets 95 concentrically within which are the upstanding studs 96 unitary with the lower section 9% which are surrounded by the springs in compression between the top of the platen section 9%- and the shoulders 97 at the upper ends of the spring sockets.

The screwsSS which have their heads in countersunk sockets therefor alined with the spring sockets 95 have their shanks passed through holes therefor of reduced diameter and axially into the upstanding studs 96,

so that to all intents and purposes, except as regards practicability of assemblage the stuns and headed screws are as integral parts.

The lower platen section is fitted in a broad, shallow, inverted, groove or recess, therefor in the upper section, with sufficient clearance for receding in an upward direction to widen the space between it and the top of the bed 10 as, in its operation over the tops of pencils, may be required.

The carriage 50 which carries the inking rolls and 66 is peculiarly constructed and operable so that the body of the carriage and its rollers may yield and accommodate themselves to inequalities in the surfaces or kind of the ink supplying disks 67 and the type form And as seen in the enlarged cross section Fig. 6, the body 102 of the carriage on which the inking rolls are carried is made separately from and spring supported from the bar 101 which engages through slots 108 in the side cheeks of the irriage, said bars by their outward e; tremities being provided ith rollers 10%: which have running engagements in the aforementioned side grooves 27 whereby the bar or rider 101 while freely sliding lengthwise f the machine is always maintained at a fixed level. A pair of rods 105 by their eye formed lower ends embrace the rider bar 101 and upwardly project through holes therefor in the ca "riage above the top of the carriage receiving at their pressure eXtrem ties the spiral springs 107 which are held in compression by the nuts 108.

The tendency of the springs is to force the carriage downwardly relatively to the rider bar and until resisted by whatever surface the carriage sustained inking rolls may be running upon, whether it be the ink supply disk, the machine bed or the type form, and the yielding upwardly as accommodated by the slots 103 is against, and increases the compression of, the springs.
