FREDERICK R. FULLER, OF WORCESTER, MASSACHUSETTS, .ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

CLICKING-PRESS.

To all whom 'it may concern:

Be it known that I, FREDERICK R. FULLER, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Clicking-Press, of which the following is a specification.

This invention relates to presses and par- .ticularly to a so-called clicking press,

that is, a press adapted to operate with dies for cutting upper leather and similar sheet material.

The principal objects of the invention are to provide a construction of clicking press which can be set up directly in a front of a window, without interfering with its operation, which constitutes a great advantage over those forms of clicking presses which must be set up at the side of a window, where the light is load at certain times of the day; to provide means whereby the column supporting the press arm may be adjusted along the block or table, even beyond the ends thereof; to provide improved means for holding the arm and for adjusting its height; to provide means whereby the angle of the press arm may be adjusted; to provide convenient and eflicient means for adjusting the height of the table or block without impairing the rigidity of its support; and generally to improve the construction of machines of this character.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which,

Figure 1 is a front view of a practicable embodiment of the invention, Fig. 2 is a similar view slightly enlarged, showing a part of the means for adjusting the height of the table, Fig. 3 is an end view of the same. Fig. 4 is a transverse sectional view of a part of the table and guiding means thereon, showing the press arm and column partly in section and partly in elevation. Fig. 5 is a front elevation on an enlarged scale, showing the column for the press arm and connected parts, Fig. 6 is an end view of the operating eccentric and clutch memher, and Fig. 7 is an end view of the other member of the clutch.

The invention is illustrated in the drawings in a form in which a frame 10 supports the table or block 11 which preferably is made up as usual of pieces of wood glued Specification of Letters Patent.

together so as to make a solid block having.

connected by a plate 13. The Wedges oneach side of the block are supplied with a nut 14 and engaging the two nuts is a right and left hand screw 15 on which is shown a worm wheel .16. The wheel is shown as operated by a worm 17 on a shaft 18 to which a wrench or handle can be applied for turning it. As the wedges are mounted with their acute angles or sharp edges extending inwardly, it will be seen that the turning of the screw 15 will either draw them together or force them apart, resulting in a corresponding rise or fall of the table.

It will be observed that the frame 10 is provided with uprights 20 at the front of the table, and that beyond the ends of the table there are projections 21 extending outwardly from the ends of the frame. Supported by these uprights and projections are longitudinal horizontal guides 22 and 23. The guide 23 at the bottom is provided with a V-shaped u iper surface and the guide 22 at the top with a V-shaped lower surface. The top guide 22 also is provided with a 1011- gitudinal head 24. on its front side. Adapted to slide along these guides is a support 25 having ways or grooves 26, 27 and 28, fitting respectively the two V-shaped surfaces and the bead. This support carries a col umn 30, which is mounted in vertical position and can be adjusted along the guides, even to positions beyond either end of the frame and table.

The projections 21. are provided with bearings 31 for a shaft 32 which is the operating shaft'of the machine and which is provided with a longitudinal key way 33. This shaft passes through the column 30, in which is located the clutch member 34 having a key 35 fixed thereto extending into the key way 33 irrespective of the position of the column. This clutch member is mounted opposite another clutch member 36 and a spring 37 normally forces them apart. Clutch member 34 however, is operated by a wedge 38 which is operated by a rod 39 and is normally held up at one end by spring 40. The rod 39 has a pivoted operating handle 41 on the outside of the column, provided with a spring pressed thumb lever 42 adapted to enter a notch in the column under nornialcondltions so-that the rod 1s held up by thisspring and by the thumb lever unless both are pressed. When this is done however, the springs 37 and 40 are botl1"co1n-" pressed and the clutch member 34 moved into contact with the clutch member 36. It

will be understood ofcourse, thatthe clutch member 34 constantly rotates with the shaft in all positions of the column and that when 7 pressed against the clutchinember '36 the latter also is caused to rotate, this results in rotating an-eccentric which is fixed to the- .clu'tch member86. This eccentric moves an eccentric strap 46-which is connected with a I. plunger 47 to reciprocate it vertically. This plunger projects up out of the top of the column and is provided with a partition 48 into which the lower end' of a screw 49 projects, so that this screw can rotate on the partition. On-the screw is a nut 50 which is fixed by means of bolts 51 to-a collar 52 surroundingthe plunger. This collar is shown as consisting oftwo parts bolted together. The bolts 51 project through elongated openings 53 and are directly connected with the collar, by aring 54. This ring is mounted in an annularrecess inside of the collar and is supported therein by a spring 55. The collar is provided with two projections--56 having a'space between them into which projects the press arm 57 Thispress arm is pivoted on a curved projection 58 on thecollar and is provided with a curved slot 59 :concentric therewiththrough which projects a bolt 60 by which the angle of the I plunger is a hand'nut 61 fitting the screw press arm is adjusted. On top of the 49 for adjusting'the collar and press arm as a 'whole vertically, independently of the plunger. The spring yields as the arm comes down and allows the cam toswing over the dead center. It will be seen that by such a construction, the block can be setup directly in front of a window and that an pel ectric light can be-nsed to advantage, as

1 the press arm can be moved to any point :necessary to secure the best light onthe work On 'certain'classes of work this adds more than an hour per day to theeflective working timeof the machine. Another advantage is that the eccentric cannot operate tw ce for one, operation of the operatinghandle 41, becausewhen the operator lets go of the'handle-the spring 40 moves itback so that the lever '42 enters its notch and the wedge 38 is withdrawn. This'prevents ac- 'cident by a second operation of the press arm.

- preferred embodiment of this invention, I am aware that many modnications can be made therein by any person skilled in the art without departing from the scope of the inventlon as expressed 1n the clalms.
