SOLOMON B. FEUERS'IEIN, OF CHICAGO, ILLINOIS.

PRINTING-PRESS.

Specification of Letters Patent.

Patented J an. 23, 1215.

Application filed April 15, 1913. Serial No. 761,176.

To all whom it may concern Be it known that I, SOLOMON B. FEUER- STEIN, a citizen of the United States, resid ing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Printing- Presses, of which the following is a, specification.

This invention relates to printing presses and has for its general object the production of a small job-press of novel and improved construction.

While the machine herein disclosed is capable of use for various purposes, it is particularly designed for printing monograms and the like on letter-writing paper or other desired material.

It is one of the objects of the invention to produce an improved inking apparatus for printing presses of this character.

The invention contemplates the provision of a press for the purpose described which shall be of small and compact construction, convenient in operation, and cheap to manufacture.

The novel features and advantages of the invention will be fully set forth in the following detailed description.

In the accompanying drawings, Figure 1 is a side elevation of a printing press embodying the features of my invention. Fig. 2 is a front elevation thereof. Fig. 3 is a horizontal section taken in the plane of line 3 3 of Fig. 1. Fig. 1 is a vertical section in the plane of line l 41 of Fig. 1. Figs. 5, 6 and 7 are sectional detail views on lines 5, 6 and 7, respectively, of Fig. 1. Fig. 8 is a sectional detail on line 8 of Fig. 3.

The preferred embodiment of my invention which I have herein shown comprises a framework consisting of a bed 10 and a frame or bracket 11 rising therefrom. In the upper portion of said frame is mounted a horizontal drive shaft 12 having a drive sheave 13 loosely mounted thereon. Said sheave may be continuously driven by a motor (not shown) belted thereto. The sheave has a clutch hub 14 having a lug 15 thereon arranged to engage a pin 16 fixed in a collar 17 which is rigidly secured on the shaft 12. A collar 18 is fixed on the shaft 12 at the outer side of the sheave 13. The sheave is arranged to be slid longitudinally of the shaft to bring the hub 14. and the collar 17 into clutch engagement by means of an angular lever 19, which extends downwardly through a slot in the frame 11 and is pivoted on a pin 20 seated in said frame. At the upper end of said lever is a fork 21 which engages in a groove 22 in the hub 1-1 of the drive sheave. The horizontal end of the lever 19 is attached to link 23 which extends downwardly and may be connected to a treadle. I have deemed it unnecessary to illustrate the treadle herein. A coiled spring 241, attached at one end to a screw 25 in the lever 19, and at its other end to 2. lug 26 projecting downwardly from the bed 10, tends to swing the lever 19 in a direction to slide the sheave 13 out of clutch with the collar 17, so that the sheave will rotate idly on the shaft 12. The bed 10 is arranged to rest upon a suitable table or support A with the lever 19 and the lug 26 projecting downwardly through a slot B in said support.

The printing platen comprises a metallic plate 28 having an impression plate 29 of suitable composition on its upper side against which the type in the printing head is pressed. The plate 29 may be secured to the plate 28 by interengagingedge portions indicated at 30 in Fig. 8. The plate 23 is seated in a recess 31 formed in the upper face of a raised portion 32 on the forward end of the bed 10. The plates 28 and 29 are held in proper position in the present in stance by a pin 33 fixed in the bed 10 and entering a recess in the plate 28. Said plates may be lifted out of the recess 31 and out of engagement with the pin 33.

The paper positioning means comprises a horizontal rod 35 which is adjustably mounted in a yieldable clip 36 secured to one side of the bed 10 by means of a bolt 37. A horizontal bar 38 is fixed crosswise on the forward end of the rod 35, and on said bar is slidably mounted a clip 39 having an angular lug or arm 40 at one end. The bar 38 and the lug 40 form a corner into which one corner of the paper may be moved in positioning the paper on the platen 28, 29.

The form-carrying element 12 is positioned above the platen 28 29 and is fixed on the lower end of a plunger 13 which is mounted for vertical reciprocation in bearings 44 in the frame 11. The detail construction of the element 42 is illustrated in Fig. 7 and comprises a portion 15 which is rigid with the plunger and a chase 16 which is detachable from the portion 45. The chase 16 has an undercut groove 47 in its upper face which is adapted to receive a bevel-faced bar 48 secured in the lower face of the portion 45. The chase 46 may be slid along the bar 48 to disengage said chase from the fixed portion 45. The form, not herein shown, is secured in a recess 49 in the lower end of the chase 46, being held in said recess by means of a clamping screw 50.

Between the bearings 44 the plunger 43 is provided with a cam 51 having a central opening, the larger portion of which is defined on the arc of a circle, and the lower side of which is substantially flat or horizontal. A plate 52 secured to the front side of the cam 51 closes the central opening therein. ()n the forward end of the shaft 12 is fixed an arm carrying at its end a roller 54, which arm and roller lie within the central opening in the cam, the arcuate portion of said opening being concentric with the shaft 12 when the cam is in its normal or uppermost position. In the lower portion of the opening in the cam is fixed a wedge member having an inclined upper face upon which is slidable a cotiperating wedge member 56, said members having a suitable interlocking rib connection 57. The member 56 may he slid by a screw 58 threaded in an opening in the cam 52 and having a head 59 at its inner end which engages in an opening in the member 56. Upon the outer end of the bolt 58 is fixed a head 60, and a lock nut 61 is threaded on said bolt and bears against the cam In the rotation of the shaft 12 the roller 54 is carried into engagement with the member 56 so that the plunger 54 will be periodically depressed. The normal height of the form-carrying element 42 and the limit of its downward moveinentmay be adjusted by sliding the wedge member 56 on the member as will be readily understood. In this manner the degree of pressure of the form against the paper may be varied at will. The plunger -43 and frame 11 may be pro ded with vertical guide faces 62 which slide in con tact with each other. The plunger 43 is normally held in its uppermost position by a coiled compression spring 63 which surrounds the upper end of said plunger and bears against the bearing 44 and a cap plate 64 secured to the upper end of the plunger. A suitable housing 65 incloses the upper end of the plunger and said spring and plate.

The inking means comprises a circular inking plate 68 having a rigid central stem 69 projecting downwardly therefrom and rotatably mounted in a sleeve 70. Said sleeve is adjustably mounted in the bed 10, preferably being externally screw threaded and turned into a threaded opening in the bed. A look nut 71 is threaded on the lower end of said sleeve and bears against the under face of the bed 10 to lock the sleeve to the latter. Openings 72 may be provided in said sleeve to receive a spanner wrench for turning the sleeve to adjust the height thereof. ln a bearing 73 in the frame 11 is rotatably mounted a vertical shaft 74 having a bevel gear '75 fixed on its upper end, which gear meshes with a bevel gear. 76 fixed on the drive shaft 12. On the lower end of the shaft 74 is fixed a head 7 7, and in'said head is secured a pair of horizontal shafts 78 on which are mounted inking rollers 79. A plate connects the outer ends of said shafts. In order that the head 77 may be adjustable to compensate for wear on the inking rollers 79 and to properly position said rollers with relation to the face of the form, said head is threaded on thelower end of the shaft 74. A lock nut 82 threaded on said shaft secures the. head 77 in its adjusted position.

In the operation of the machine, a sheet of paper is laid on the impression platen 29 and is properly positioned by moving it into engagement with the stop devices 38 i I and 40. The operator then depresses the treadle to swing the lever 19 and-thereby move the drive sheave 13 into clutch with the shaft 12. Said shaft will now be driven to rotate the shaft 74 and thus carry the inking rollers 79 first overthe face of the inking plate 68 and then along the'lower face of the form in the chase 46. The shaft 74 is eccentric to the inking plate 68, and each time the rollers 79 move over said plate they act to impart a partial rotation to the It is, therefore, unnecessary to proplate. vide any special means for rotating the inking plate. When the cam arm 53 engages the wedge member 56, the form-carrying element 42 is depressed into contact with the paper on the platen 29. The plunger 43 is returned upwardlyloythe spring 63 as soon. as the cam arm 53 has passed to one side of the member 56. The operator new releases the treadle to unclutch the driving sheave 13, and positions another sheet of paper on the platen. when he again depresses the treadle, and the cycle of movements abovedescribed is repeated.

When the inking rollers 7 9 become worn. or when adjustment isnecessary for any other reason, the lock nut 82 may be loosened and the head 77 given a complete revolution to raise the rollers so that they will properly contact the face of the form in the chase 46. The inking plate 68 may be vertically adjusted to correspond to the position of the rollers 79 by loosening the lock nut 71 and turning the sleeve 70 in its opening.
