To a/ZZ whom it may concern.-

. Be it known that I, JOHN EDWARD CAPs, a citizen of the United States, Vresiding at Kansas City, in the county lof Jackson and State of Missouri, have invented a new and useful Printing-Press, of whichl the following is a specification.

Heretofore in color-printing machines and, in fact, presses of various types considerable diliculty has been experiencedin changing the forms. This is usually an operationrequiring considerable time, and while movable carriages carryingportions of the mechanisms have been devised it has, nevertheless, demanded thekservice of experts to readjust the various elements after the desired changes have been made. Such changes therefore are rather expensive, as they necessitate thestoppage of the press for a considerable length of time, besides the employment of skilled workmen.

It is the object of the present invention to overcome these various objections by providing mechanism which will permit the ready disassociation of the elements and their reassembly without undue loss of time and without the particular necessity. of expert workmen. To this end relatively movable supports are employed carrying different portions of the mechanism, which portions can thus be separated to permit access to the printing-cylinders. Said cylinders are removable bodily from the structure and are so mounted that when replaced and the parts again moved into operative position the various elements will assume their proper relation with respect to one another. However, should it become necessary to adjust any of the parts eflcient means of a very simple nature is provided for this purpose, and said adjusting means is entirely accessible.

Other important features of the invention relate to means for locking the parts in operative position, said means securely holding the apparatus against accidental displacement.

The .embodiment illustrated in the accom-- panying drawings and described in the following specification is at present believed to be viewon the line 3 3'of Fig. l. detail end elevation illustrating the manner of the most desirable; but the claims hereto appended are drawn broadly enough toinclude various changes and modifications from the structure set forth, and the invention is therefore not limited to the details of construction shown Yand described.

In the drawings, Figure 1 is a side eleva- 55 tion of the improved press. Fig. 2 'is a vertical sectional view through one side of the frameand carriage. and taken on the line 2 2 of Fig. 1. Fig. 3 is a horizontal sectional mounting the printing-cylinders. Fig. 5 is a horizontal sectional view taken on the line 5 5 of Fig. 4. Fig. Gis a side elevation of the same. Fig. 7 is a detail sectional view taken 65 on the line 7 7 of Fig. 1.

Similar reference-numerals indicatecorresponding parts in all the ligures of the drawings.

In the embodiment herewith set forth a suitablestationary frame is employed, comprising standards, 1 0 and upper and lower tracks l1, the lower tracks being bolted, as shown at 12, to a suitable bed or base 13. The operative faces'of the tracks are arranged in 75 opposing relation and are provided with overhanging treads 14. A carriage 15, comprising a suitable frame, is movably mountedin the stationary frame between the tracks 11 `and is provided with u'pstanding and depend- 8O ing spaced flanges 16, forming guides 17, that slidably engage the tracks 11. The carriage is thus movable toward and from the standards 10, and in order to accomplish this movement one of the depending flanges 16 is pro-,85 vided with a suitable rack 18, engaged by an actuating-pinion 19, mounted on a stub-shaft 20, that is journaled in the lower track and has an angular. outer end adapted to be engaged by an operating wrench or tool.

Mounted upon' the standards 10y is suitable impression mechanism, preferably in the form of cylinders 2l, only one of which is shown, though it will be seen by those 'Skilled in the art that any number may be employed as desired. It is believed to be unnecessary to go Fig. 4L is a 60' into further detail regarding this mechanism, as it constitutes no part of the present invention when considered by itself. Upon the adjacent portion of the carriage is mounted the printing mechanism, preferably comprising cylinders 22, having suitable grooves 23 to permit the securing of the forms or typeplates thereon. It will be also understood that any number of these printing-cylinders may be employed, and the inking mechanism eoaeting with the cylinders is preferably located on the carriage in rear of the same.

One of the improved features of the invention relates to the means for mounting the printing-cylinders 22. It will be observed that seats 24 are formed in the side of the carriage adjacent to the standards, and in these seats are slidably mounted boXings 25, that can be adjusted by screws 26, threaded into the inner sides of the boxings and having heads 27 bearing against the rearwalls of the seats, said heads being provided with sockets 28, arranged to receive an actuating device. J am-nuts 29 are threaded upon the adjustingscrews and bearing against the boXings serve to prevent accidental rotation of said screws. The boxings are held against displacement by means of retaining-clips 30, which, as shown in Fig. 4, are provided with longitudinal slots 3l, and through these slots are passed holdingbolts 32, threaded into the carriage. Through the lower ends of the retaining-clips are passed clampingscrews 33, that bear against the outer faces of the boXings, and` thus prevent any play of the same. The printing-cylinders 22 have elongated gudgeons, which are journaled in the boXings 25 and passing through the same project a considerable distance beyond, forming handles 34. V[t will be seen that with this structure when the carriage is moved back from the impression mechanism the printing-cylinders may be bodily removed by first displacing the retaining-clips. The boxings are removable with the cylinders, and therefore as they carry the adjusting devices it will be evident that when said cylinders are replaced they will properly position themselves upon the carriage, so that when said carriage is again moved forwardly the printing-cylinders will assume their proper relations with respect to the impression-cylinder and without particular adjustment. At the same time should such adjustment be necessary it can be readily obtained by turning the screws 26. After the adjustment has been obtained the clamp-screws 33 being turned up against the boxings readily fasten said boxings against movement upon the carriage. This portion of the structure therefore has decided advantages in that a plurality of cylinders may be employed and one set may be prepared with printing-plates while another set is in operation, so that when a change is desired the set may be removed from the machine and replaced by a new one without serious loss of time.

In order to properly position the carriage with respect to the impression mechanism, adjustable stops in the form of screws 35 are thread ed into the end of the carriage adjacent to the standards and are provided with heads 36, which are arranged to abut against said standards. Jam-nuts 37 are preferably employed to hold the screws against accidental movement. These stops are arranged upon the upper and lower ends of the carriage, so that when said carriage is in its forward position it will be iirmly iixed. It will be evident that by adjusting the screws the distance between the carriage and the standards, and consequently the relation of the printing and impression cyinders,can be readily and quickly changed. Means of a novel nature are also employed for locking the carriage in its operative position. These meansarein the form of sliding lockslocated in the rear of the carriage and fitted upon the tracks ll. Said locks each colnprises a section 38, that rests upon the tread of the tracks and flanges 39, embracing the same, while another section 4d engages the offset face of the overhanging flange 14 of the tracks and is secured to the first-mentioned section by bolts 4l. A clamping-screw 42 is threaded through an outstanding ear 43 on the section 38 of the lock and is arranged to bear against the rear face of the carriage. These locks are preferably employed on all the tracks.

1t is believed that from the foregoing description the operation of the apparatus will be entirely clear. When in operative relation, the carriage is located adjacent to the standards, so that the printing and impression cylinders are in coacting relation. ln separating said cylinders the locks are iirst nuclamped from the tracks by loosening the bolts 41, and thereupon the carriage may be moved backwardl y through the medium of the rack and pinion. The printing-cyliriders can thereupon be removed, as already described, and when replaced by others the carriage is returned to its original position, or, in other words, until the stops engage the standards. This, as above set forth, properly positions the elements, and after the locks have been returned and clamped said carriage is securely fastened by moving the screws 42 inwardly against the same. By means of these various devices, therefore, the carriage is absolutely fixed, so that it cannot become in any manner displaced by the vibration or motion of the parts. At the same time it can be readily released and moved when desired. lV ith a structure of this sort little time is lost in changing forms, and, moreover, such changes do not require the services of an expert even should adjustments be required, as of course may become necessary from wear or other causes.
