ALBERT n". COOKE, or PORTLAND, OREGON.

PRINTING-MACHINE.

Specification of Letters Patent.

Application filed April 8, 1909. Serial-No. 4=88,6S5.

T 0 all whom it may concern:

Be it known that l, ALBERT D. CooKE, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful improvements in 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.

This invention relates to new and useful improvements in printing machines of the hand-operated type, and has for its object to provide a simple and efliciently operating device of this character, comprising means whereby the head and side margins of the paper to be printed upon may be readily gaged, means for cutting the paper into strips of suit-able widths after passing under the printing roller, and improved means for feeding'the ink to the printing roller or cylinder.

With the foregoing and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

In the embodiment illustrated, Figure 1 is a side elevation of a printing machine embodying the present improvements; Fig. 2 is a top plan view of a portion thereof partly in section; Fig. 3 is a horizontal section taken on a plane something above the feeding and cutting mechanisms; Fig. l is a detail fragmentary view, on an enlarged scale, of a section of the feeding device, used in connection with the preferred embodiment of the invention; Fig. 5 is a similar view of the strip-separating means; Fig. 6 is a side elevation of a modified form of the invention; Fig. 7 is a vertical transverse section, taken through Fig. 6; Fig. 8 is a transverse section, taken on the line 88 of Fig. 7 and Figs. 9 and 10 are detail views of the means for oscillating the ink-distributing roller, and Fig. 11 is a detail fragmentary view of a portion of the carrier and carrier frame.

In the embodiment illustrated, the numeral 1 indicates a suitable upright supporting frame, in which is revolubly mounted the printing roller 2. This roller or cylinder is provided upon its exterior surface and for approximately its entire length with a square thread 3, and screwing upon the exterior or peripheral surface of said cylinder are type-holding rings a, which may be adjusted to hold the type in proper position upon the cylinder, and retained in such adjusted position by retention screws 5, it being understood that type, usually called stereotype, is used, the same having been cast and formed especially for this type of printing machine. Secured to the righthand end of the printing cylinder is a gear wheel 7 which intermeshes with a train of gears S, 9 and 10, respectively, the latter of which is carried by the shaft upon which the ink-feeding roller 11 is fixed. The ink-feeding roller 11 works in the ink fountain 12 (as shown) and passes the ink to a distributing roller 13, which is suitably mounted in the upper end of the main frame 1, said roller 13 delivering the ink to the inking roller 14 which travels upon the exterior surface of the printing roller or cylinder 2. The inking roller 14 is revolubly mounted in the upper forked ends 15 of bearings 16 which are slidably mounted in off-sets or lugs 17 formed at opposite sides of the main frame 1, springs 18 being arranged around the lower ends of the bearings 16, between said lugs and nuts 19, screwing upon the lower ends of the bearings. By mounting the inking roller in position in this manner, it will be observed that it is always maintained in contact with the printing cylinder 2 with the desired pressure, and that any wear upon the inking roller is readily compensated for.

The scraper 20 is slidably and adjustably mounted in advance of the feeding roller 11, with its inner side edge in engagement there with, whereby the amount of ink fed in a given time from the fountain may be fully regulated. The printing cylinder is rotated by means of an operating handle 21 rev0lubly mounted upon a stub shaft 22, projecting laterally from one side of the main frame, said handle being keyed to a gear 23, also revolubly mounted upon'said shaft and arranged to intermesh with a gear 241, arranged at the adjacent end of the printing cylinder shaft.

The paper is fed to the printing cylinder by means of an endless carrier consisting of a series of endless cords or belts 25 which pass over a suitable roller 26, revolubly mounted at the extreme front end of a longitudinal supporting frame, consisting of side and cross pieces 27 and 28, respectively, the inner end of said frame being adjustably Patented Aug. 24, 1909.

connected with the lower end of the main frame, preferably by bolts 29, passing through longitudinal slots in the side pieces of said frame, and nuts 31, screwing upon the outer ends of said bolts. The cords or belts 25 comprising the carrier also pass over a grooved roller 32 mounted in advance of the inner end of the carrier-supporting frame. A rock shaft 33 is revolubly mounted slightly in advance and on an approximate level with the top of the roller 32 and fixed to one end of said rock shaft is a trip lever 34 provided at its upper end with a roller 35, said rock shaft being further provided with a series of longitudinallyrspaced, forwardlyextending hooks 36, the function of which will he presently disclosed. One side of the printing cylinder is further provided with an adjustable arc-shaped cam 37, which is adjusted to regulate the top margin of the sheets of paper which are to be printed upon, the cylinder being provided with a gage 38 adjacent said cam to serve as a guide in adjusting the latter. The lever 34 is normally held in elevated or raised position by a spring 39 connected with the lever and one of the side pieces of the main frame. The side margin of the paper is regulated by a guide 40, which held at the proper lateral adjustment by vertical pins 41 which extend through the base of the guide and corresponding apertures 42 formed in the cross bars 28 of the carrier frame.

In the operation of the device, the sheets 3 of paper which are placed upon a suitable platform 43 hinged to one side of the carrier frame are placed one at a time upon the endless carrier by means of which they are fed to the printing cylinder. Before passing under this cylinder, however, and receiving the impression, .each strip or sheet of paper is caught by the hooks .36 of the rock shaft 33,, until the cam 37 of the cylinder engages the roller .35 of the lever 34, when the latter is depressed and the hooks lowered out of engagement with the sheet, when the latter passes between the printing cylinder and a spring pressed roller 44 suit-ably mounted beneath the same. As heretofore explained, the printing cylinder is rotated by means of the handle 21, while the grooved roller 32 is rotated by a belt 45, which passes over a grooved roller 46,, mounted upon the roller shaft, and over a second pulley 47 on the stu shaft The cutting device comprises a pair of vertically spaced rollers 48 and 49, respectively which are suitably mounted in front of the rbll 44 and provided with sets of cooperating .circular cutting knives 50 and .51, respectively, the rollers 48 and 49 being proj vided with grooves 52 spaced equal distances apart in order that the cutting knives may be spaced a greater or less distance apart by set screws which engage said grooves.

I will now describe a receiver for collecting the strips cut by the knives 50 and 51.

As shown, this receiver comprises a base 54 which has an adjustable connection with the main frame in advance of the knife-carrying rolls, and is provided in its top face with a series of equally spaced longitudinal grooves A series of longitudinal partitions 56 are pivotally mounted at their forward or outer ends upon a shaft 57 suitably sup ported above the adjacent end of the base .54, and when in lowered position the lower edges of said partition fit in certain of the grooves in the face of the base 54 of the receiver.

From the foregoing it will be readily .observed that the partitions may be spaced greater or less distances apart to receive strips of different widths, the partitions being always placed in direct alinement with the cutting knives. The upper roller 49 of the cutting knives is driven by a belt 57 which passes over a grooved pulley 58 mounted upon the stub shaft 22 and .con- I nected with the pulley and gear 47 and 23,

respectively, and over a second grooved pulor intersecteach other and the block 62 is mounted beneath and in position to travel in said threads, By this construction, the distributing roller is caused to oscillate longitudinally and thereby eventually distribute the inkto the inking roll 14. It is evident that any other well known means may be used for effecting oscillatory movement of the distributing roller, the present construction having been merely shown for illustrative purposes.

Instead of feeding the paper to the printing cylinder in strips and by hand, it may be fed from a continuous roller 61 (see Figs. 6 and 8), in which case the carrier, carriersupporting frame, and certain other parts will be necessarily dispensed with. In this case the following means is employed for cutting the roller into strips of the desired length. One end .of the printing roll is provided with a series of rollers 62 which engage arms or extensions 63, fixed to opposite ends of a rock shaft 64 mounted in ad- Vance of the printing roller. This rock shaft is further provided with a pair of forwardlyprojecting arms 65 to the free ends of which is connected a slide carrying a cutting knife 67, the ends of the slide 66 fitting in corresponding recesses 6.8 in frames 69, mounted upon the receiver base. A second fixed I cutting knife '70 is arranged beneath the movable cutting knife 67 in position for its forward edge to cooperate with the same in cutting the paper into sheets or strips. The arms 65 are normally held in raised or elevated position by springs 71.

From the foregoing description, taken in connection with the drawings, it is thought that the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Having thus described my invention, what I claim as new and desire to secureby Let-- ters-Patent is:

1. In a printing machine of the class described, a printing mechanism including a printing cylinder, a feeding mechanism to feed the paper to the printing cylinder, a rock shaft provided with a series of paper engaging hooks mounted beneath the printing cylinder and in advance of the feeding mechanism, a trip lever fixed at one end of said shaft, a spring to hold said lever in elevated position, an adjustable cam at one end of the printing cylinder to actuate or depress the trip lever of the rock shaft at each revolution of the printing cylinder, a cutting mechanism to cut the paper into strips arranged in advance of the printing cylinder, and a receiver to receive the strips arranged in advance of the cutting mechanism.
