Specification of Letters Patent.

Patented Mar. 18, 1915.

Application filed July 16, 1914. Serial No. 851,353.

To all whom it may concern Be it known that I, HARRISON H. EATON, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Clicking-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the draw ings indicating like parts in the several figures.

This invention relates to presses and particularly to improvements in the provisions for adjustments in presses of the type employed to cut out upper leather for boots and shoes.

In its illustrated embodiment the invention is shown as applied to the type of press disclosed in U. S. Letters Patent to Arthur Bates No. 921,503, dated May 11, 1909, in which the presser member is carried by a vertically reciprocating plunger and is movable in a horizontal plane over a cutting bed, a starting arm movable with the presser member laterally and movable relatively thereto for actuating the machine being located above the presser member. In the use of the press disclosed in said Letters Patent the presser member is adjusted relatively to the cutting bed according to the thickness of the material upon the bed or the heights of the dies used and also to compensate for the wear of the bed. This adjustment of the presser member necessitates a corresponding adjustment of the starting arm in order that the proper cooperation between said arm and the presser member and also between said arm and the clutch mechanism may be obtained.

It is an object of the present invention to improve the means heretofore provided for such adjustment. To this end a simple and efficient means has been devised whereby the starting arm may be adjusted in two directions in the plane of the relative movement of the arm and the presser member in order to maintain a substantially constant relationship of said arm to the presser member in the difi'erent positions of adjustment of the presser member.

Other objects of the invention will appear from the following description and claims when considered in connection with the accompanying drawings in which- Figure 1 is a side elevation of a machine embodying the present invention; and Fig. 2 is a detail section.

A stock supporting bed 2 is secured to or formed as part of the frame 3 of the machine and is adapted to support the material to be operated upon. The presser arm 5 is rigidly secured by bolts 6 to a plunger 7 supported vertically in bearings 8 and 9 on an upwardly extending portion of the machine frame. The plunger 7 is arranged to turn in said bearings so that the presser arm 5 secured thereto may be moved laterally in a plane substantially parallel to the bed and is also arranged to receive a vertical reciprocation which is efi'ected by connections with an eccentric upon a driving shaft 12 to which may be clutched by suitable clutch mechanism a loose driving pulley 13. The clutch is actuated by a rod 15 connected at its upper end to the rear end of a lever 16 fulcrumed at 18 in the frame and having a connection at its forward end to a starting handle 20 mounted on a vertical spindle 22 carried by the presser arm 5. The forward end 23 of the lever 16 surrounds the plunger 7 with suflicient clearance to permit the movement of the lever and is provided with an annular recess into which fits a ring-like member 25 having an outwardly projecting lug to receive one end of an arm 28, the opposite end of which fits into a groove in the starting handle 20, a spring 29 normally holding the arm 28 and starting handle in elevated position.

The presser arm 5 may be adjusted vertically relatively to the cutting bed 2 by a hand wheel 32 and a screw threaded connection (not shown) with the plunger 7 such as shown and described in the patent above referred to in order to accommodate the arm to the different work thicknesses on the cutting bed or to dies of different heights and also to compensate for the wear of the bed. This adjustment necessitates a corresponding adjustment of the starting connection so that the proper cooperation between the presser arm and the starting mechanism may be maintained. The improved means for accomplishing such an adjustment con hub. Two set bolts 36 are received in threaded openings in the upper portion of the hub 32 and project into the bore on either side of the highest portion of the opposite surface. It will be seen that the end of the arm 28 received by the hub 32 is engaged at three different points, the point 38 of the convexed surface of the bore providing a support for the arm in the bore while the ends of the set bolts extending into the bore engage the upper surface of the arm on both sides of the point 38 and securely hold the arm in said bore. When the presser arm is vertically adjusted relatively to the bed 2 the set bolts 32 may be adjusted to effect a corresponding vertical adjustment through the arm 28 to the starting handle 20 in order to maintain a predetermined relationship between the presser arm and the lever a'nd also a longitudinal adjustment of the arm 28 so that its forward end may be retained in a position properly to support the starting l'iandle on the spindle 22 of the presser arm, this longitudinal adj ustment being necessary owing to the arc in which the end of the arm 28 travels during its vertical movement.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a clickin machine, the combination with a laterally movable and vertically adjustable presser member, of an actuating lever arm movable with said presser member laterally, and movable relatively thereto Copies of this patent may be obtained for five cents about a fixed fulcrum when actuating the machine, said arm being constructed and arranged for adjustment in two directions in the plane of said" relativemovement in order to maintain a substantially constant relationship to said presser member in the different positions of adjustment of said member. 7

.2. Ina clicking machine, the combination with a laterally movable and vertically adjustable presser member, of a two-part aetuating lever arm movable with said presser member laterally, and movable relatively thereto about a fixed fulcrum when actuating the machine, said two parts-of said arm being connected with provision for adjust ment in two directions in the plane of said relative movement in order to maintain a substantially constant relationship to the presser member, in the dilierent positions of adjustment of said member, of that end of the arm which is adjacent to the operator.

3. In aclicking machine, the combination with a laterally movable and vertically adjustable presser member, of a two-part actuating lever movable with said presser member laterally, and movable relatively thereto about a fixed fulcrum when actuating the machine, one part of said arm being provided with an adjustable three-point bearing to receive the other part of said arm whereby the end oi the arm which is adjacent to the operator may be adjusted in two directions in the plane of said relative movement in order to maintain a substantially constant relationship to the presser member in the 'diiferent positions of adjustment of said member. a

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. Q 1
