Patented Oct. 3, 1905.

Application led February ll, 1904. Serial No. 193,080.

Be it known that I, HOBERT J. HURD, acitizen of the United States,`and a resident of Bridgeportjn the county of Fairlield and State of Connecticut, haveinvented certain new and useful Improvements in fad-Printing Machines, of which the following is a specification.

My inventionrelates to improvements in machines for printing gun-wads on both sides; and it consists in certain details of construction to be more fully set forth in the following specification, and such features that are believed to be new and novel will be partielllarly set forth in the claims.

To enable others to understand myinvention, reference is had to the accompanying drawings, in which- Figure 1 represents a side elevation of the machine and broken view of its standard and wad-feeding mechanism. Fig. 2 is an upper plan view of the machine. Fig. 3 is an enlarged central sectional view of the gear, having a cam on its vertical face adapted to actuatc the vertically-operating slides pertaining to the printing' mechanism, sectional View of said slides, enlarged View of the upright, and sectional View of the wad-magazine through line e of Fig. 2. Fig. 4 is an enlarged broken sectional View of the support on which the cam-gear actuating the slide of the printing mechanism rotates through line 7) of Fig. 3, also upper plan View of the wad -feeding mechanism. Fig. 5 is an enlarged detail View of the distributing and inking rolls, broken view of the inlzing-pads, broken view of the type-carriers. and sectional view of the inkfountain. Fig. 6 is an enlarged upper plan view of one of the distributing-rolls and one of the inlring-rolls and frame for same. Fig. 7 is an upper plan view of the wad-feeder and broken view of its supporting-bracket, showing the method of feeding the wads. Fig. 8 is a similar view showing wads of smaller diameter being fed.

Its construction and operation are as follows:

l is the standard of the machine; 2, the bed.

3 is the driving-shaft, carrying the handwheel 4, tight pulley 5, and loose pulley 6. The shaft 3 is journaled in the bracket 7, secured to thc upright 8. 9 is a pinion on said sha ft registering with the large gear 10, Figs. This gear is rotatably mounted on 1 and 3.

the hollow journal 8"L of the frame 8 and is provided with the cam-groove 11 on its vertical face to receive the rolls 12 and 13, which rolls are mounted on the head of the screws 14 and 15, secured to the vertically-operating slides 16 and 17. 18 and 19 are housings projecting from these slides, which slides carry the adjustable shells 2O and 21, and their threaded ends carry the nuts 22 to adjust the vertical position of these shells. 23 and 24 are typecarriers mounted in said shells, the reduced portions 23a and 24 passing through the ends of said shells. 25 and 26 are adjusting-nuts mounted on said threaded portions for the purpose of adjusting a spring placed between a shouldered portion of the type-carrier and the ends of the shells. One of said springs 27 is shown at Fig. 3. These springs permit the type-carriers to react or give back slightly under the printing blow.

28 and 29 are type mounted in the inner ends of the type-carriers.

The worm or screw wad-feeder consists of the body portion 30, having the coarse thread 30u. This feeder is rotatably mounted in the adjustable box 31 and is intermittently rotated through the medium of the drivingshaft 3 as follows: 32 is a plate, Figs. 1 and 2, mounted on the end of said shaft, and it carries the screw 33. 34 is a connecting-rod having one end pivotally supported on this screw and its other end on the screw 35 ofthe arm 36. The hub portion 36n of this arm is journaled on the screw 37, projecting from frame or upright 8. 38 is a pawl pivotally supported on the arm 36, adapted to engage with the notched plate 39 of the gear 40, rotatably mounted on the stud or screw 37. This gear meshes with the pinion 41 of the wadfeeder to eifect an intermittent rotary movement of said feeder through the medium of the mechanism just described.

42' and 43 are ink-fountains having a longitudinal adjustment (see also Fig. 5) through the medium of the elongated holes 44 and 45, embracing the side clamping- screws 46 and 47. 48 and 49 are fountain-rolls journaled on the pins 50 and 51 in the end of said inl(- fountains.

52 and 53 are ink-Scrapers adapted to be' adjusted to and from the fountain-rolls by means of the adjusting-screws 54 and 55 (see also Figs. 1 and 2) to remove surplus ink from the surface of said rolls. These rolls vof are iluermittently rotated as follows: 56 is i l and lower type.

cam-plate mounted on the shaft 8 and has on its outer periphery the projection 56" to engage with the roll 57', mounted on the lower end of the vertical link 59 and 60 are arms carrying` the pawls 61 and 62, adapted to engage with the ratchet-wheels 63 and 64,

secured to the pins and 51 of the Vfountain-rolls. One end of thel said arms is journaled on the said pins and the other end on the screws 65 and 66 of the link 58.

67 and 68 are the inking-pads secured to the frame or upright 8 and are vertically adjustable thereon.

69, Fig. 1, is a reciprocating slide adapted to operate through the medium of the level' 71, whose upper end carries the link 72, connected to said slide. The lower end of this lever is journaled on the pin 73, projecting from the bed of the machine, while intermediate of the ends of this lever is the roll 74, adapted to engage with the cam-groove in the inner vertical face of the cam-plate 56.

Referring to Fig. 76 is a stud projecting from the slide 69, and 77 and 78 are levers pivotally supported on this stud. 79 and 80 are Vframes pivotally supported on the outer ends of these levers, and 81 and 82 are the ink-distributing rolls, and 83 and 84 are the inking-rolls journaled in said frames. 85 is a spring-clip eng'aging the inner ends of said levers, so as to apply an outward pressure to said rolls. 86 is an adjusting-screw to regulate such pressure. The reciprocating movement of the slide will bring the distributingrolls against or in close proximity to the rotata ble fountain-rolls on each backward movement of the slide, and the amount of ink taken up by these distributing-rolls is determined by the closeness of this proximity and the amount of ink carried by the fountainrolls. The Yforward movement of the slide will cause the rolls 81 and 82 to distribute the ink evenly onto the surface of the inkingpads, so that the inking-rolls 83 and 84 will take up the necessary amount of ink for the type as said rolls pass over the pads.

l 87, Figs. 1, 2, 3, and 4, is the gravity-feeding wad-magazine, which is filled with the unprinted wads 88. The magazine overlies an opening' in the cap 89 of the box 31, with its foot secured to the side of said box. The wads drop Yfrom the magazine one at a time onto the cylindrical body portion of said feeder and between the threads, and they are kept from rotating' or turning' with the feeder by reason of the engagement of their edges with ythe cham'xel-way 89, formed on the under surface ofthe caps 89. As fast as one wad passes from under the magazine another takes its place and is in turn fed on toward the type in one cominuous succession.

9i), Figs. 3 and 4, is an interchangeable dieplate located at the forward end of the wadfeeder, havingl the hole 91 to admit the upper This plate is also provided with the channel-way 92 to guide the wads centrally with respect to the type. As soon as a wad is printed it is pushed out of the range of the type by the next incoming wad delivered vfrom the feeder'. The printed wads are forced along the block 93, extending through the hollow journal 8", and are delivered at its end, as shown at Fig. 4. This block has the overlying caps 94, which caps also have the channel-way 95.

The great advantage of the worm or screw Vfeeder over a dial-feeder rotating in a horizontal plane, where the wads are fed into holes circumfcrentially arranged in said dial, is the less number of parts required, more accurate delivery of the wads to the type, and the necessity avoided of changing' the size of the worm or screw 'feeder for diiierent sizes oli' wads, which is necessary where a dial-feed is used.

The pitch of the screw or space between the threads, Fig. 7, is made to receive wads of the greatest diameter required. The central portion between the threads will of course be central with the center of the magazine, so that when a large-sized wad is deposited on the feeder it will about lill the space between the threads 30, The main determining factor, however, in securing correct feeding is the engagement ofl the right-hand face of the threads with the edge of the wads, for it is this face that engages with the edges of the wads to move them forward, and therefore the location of the edge of the wads with this `face is very important.

The placing of the wads between the type so that their center (represented by the line c) shall lie central with the type is determined` by the extreme end 30" of the thread. In other words, the distance between the extreme end 30" of the thread and the center of the type is equal to one-half the diameter of the wad being fed, so that when the wad is between the tyge the thread portion of the screw-feeder exerts no further pushing inlinence on the wad, and when the wad so located is printed another wad is fed along', as before mentioned, to push the printed wad away from the type and take its place.

All that is necessary in printing wads of smaller diameter is to change the die-plate 90 for one having a channel-way which equals the diameter of the wad to be printed and move the box 31, in which the screw-feeder is journaled, forward, as follows: 96, Fig. 8, is a bracket integral with the upright 8 and is provided with the elongated holes 97 for the screws 98, which screws are attached to the box 31. WThen, therefore, smaller wads are printed, this box is loosened and moved forward against the die-plate. Then a small wad drops onto the body portion of the screwfeeder, it will lie midway of the threads; but as it cannot rotate with the feeder it will re- IOC) IIO

main stationary for an instant until the thread has caught up and engaged its edge to push it forward.

\Vhatever position the box 3l occupies, the end 30" of the thread of the screw-feeder must always stand from the center of the type a distance equal to one-half the diameter of the wads that are being printed. This po'- sition can be accurately and quickly determined by means of the lines or scale /L on the bracket and box, or, Figs. 3 and 4, the distance from the edge c' of each die plate or block to the center of its type-hole 91 equals one-half of the diameter of the wad intended to be used with said die-plate. I

To counteract the wear of the cam-groove il and the rolls of the slides which operate therein, I employ the adjustingscrews 99 and 100, Fig. 3, whose points are adapted to engage with the enlarged portion 8" of the hollow journal S" when the type engages with a wad. This makes a positive limitingpoint for the inward travel of the type.

Another great advantage of the screwfeeder over the dial-feed lies in the fact that if through the carelessness of the operator the magazine should become empty there will always be a wad between the type to prevent the type-faces coming in direct contact with each other.

The machine above described is not only cheap and simple of construction and containing but few parts, but it is absolutely correct and accurate in its operation and is capable of printing more wads in a given length of time than can be done by a machine using` a dial-feed.
