UNITED STATES ATEN T FQ JAMES E. COLLINS, OF BEVERLY, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON,

NEW JERSEY.

NEW JERSEY, A CORPORATION OF CUTTING-MACHIN E.

To all whom it may, concern:

Be it known that I, JAMES E. COLLINS, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Cutting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines a distinctive feature of which is a member that is movable intermittently at the will of the operator to impart pressure or deliver a blow to an object, and commonly comprising relatively movable members arranged to operate upon an object therebetween.

In its more limited application, my invention relates to a particular type of machine commercially known as the clicking machine, of which an example is shown in United States Letters Patent to Arthur Bates, No. 921,503, granted May 11, 1909. Such machines, as usually constructed, include a stock supporting bed, and a presser member that is movable over the bed to an operative position with respect to a die on the bed and subsequently movable automatically at the will of the operator to force the die through the stock. For illustrative purposes my invention will be shown and described as embodied in a machine of this character, although it is not thus limited in scope but in its broader aspects, as will be evident, is applicable to various other constructions of the general type referred to.

My invention relates, more particularly, to the means for controlling the operation of such machines, and the general object is to provide means whereby the operating mechanism may be actuated more readily and with the expenditure of less time and effort on the part of the operator than by prior constructions.

An important feature of the invention resides in the provision of a manually operative controlling member constructed preferably for rotary or turning movement about an axis and arranged to actuate by such movement the mechanism for effecting an operation of the machine. As applied to the clicking machine this member will preferably serve also as the means whereby the operator moves the presser member into op- Speeification of Letters Patent.

erative position, and will be so arranged that as the operator grasps said member and swings the presser member thereby, movement of the controlling member relative to that of the presser member will follow by a naturaland easy movement of the operators hand, or may if desired be effected simultaneously with the swinging of the presser member so that the operation of the machine will take place at the instant when the presser member arrives at the desired operative position.

Other objects and features of the invention will appear from the following detailed description.

In the accompanying drawings, Figure l is a side elevation of a clicking machine with my invention embodied therein. Fig. 2 is a view, partly in vertical section, showing the structural details of the controlling member.

The frame 2 of the machine supports a cutting block or bed 4: and has bearings 6 and 8 for a vertically and rotatably movable post 10 to which is secured an arm or presser member 12. In the customary operation of the machine a sheet of stock, such as upper leather for use in the manufacture of boots or shoes, is placed upon the bed 1 and a suitable die arranged in the desired position thereon. The member 12 is normally upraised above the plane of the bed a suflicient distance to clear the die, and may be swung to one side with the post 10 as a pivot so as to afford an unobstructed view of the bed. After the die is placed, the member 12 is swung to a position directly thereabove and mechanism is actuated which causes the post and the member 12 to descend and force the die through the stock and then to reascend to their former position. The bed 1 and the arm 12 thus constitute presser members that are relatively movable into and out of operative relation to each other and movable relatively also to operate upon the die. The operating mechanism for the post 10 may be of any desired construction, such for example as that disclosed in the patent to Bates previously referred to, and is not illustrated in detail. It includes, as shown, a clutch device 14, which preferably comprises a one revolution non-repeating clutch and is arranged to be actuated through means that includes a rod 16 connected to a lever 18 which is pivoted to the frame at 20 and provided with a ring member 22 loosely encircling the post, the ring member having swiveled in a circumferential recess thereof a collar 24C to which is attached a rod 26 that extends forwardly over the presser member 12. The ring member, collar and rod thus constitute an extension of one end of the lever 18 so that by a depression of the forward end of the arm 26 the clutch may be actuated, while the collar 24: may turn about the pivotal axis of the post 10 and permit the arm 26 to move with the member 12 and assume any angular position of the latter without disturbing its operative relation to the lever 18. A spring 27 attached to the lever 18 tends to hold the rod 26 in raised position. These features are substantially such as are found in the commercial type of clicking machine and need no further de scription.

For imparting to the rod 26 its actuating movement I have provided a controlling member comprising in the preferred form shown an upright handle 28 formed with an annular depression 30 for receiving the forked end of the rod 26 and having a depending cylindrical sleeve 32. Fixed upon. the forward end of the presser member 12 is a cylindrical member 34 which is arranged to be closely embraced by the sleeve 32. The

c linder 34L is formed with a cam roove 36 and the sleeve is provided with a screw 38 projecting inwardly therethrough and having a cylindrical end portion upon which is carried a roller 40 movable within the cam groove. The cylinder 84 is provided preferably with a central recess in which is seated a spring 42, the opposite end of which arranged to bear upon the controlling member so as to maintain the latter at its limit of upward movement determined by the groove 36 in engagement with the roller L0. The spring 12, it will be noted, assists the action of the spring 27, and in case the latter is of suflicient strength the spring 12 may be dispensed with. The purpose of these springs is to maintain the parts of the actuating mechanism normally in inactive position, but they should be sufficiently light to permit actuating movement thereof when required with the least possible effort on the part of the operator. A rod 4L4 projects upwardly through the central part of the recess in the cylinder 34 and fits closely in a longitudinal recess 46 in the controlling member, thereby serving to keep the spring in proper position and assisting in centcring the controlling member with reference to the cylinder 34:. Holes 1-8 serve to maintain atmospheric pressure in the space within the sleeve 32, and a hole 50 in the end of the handle performs a similar func 'tion for the recess 16.

he groove 36, the sides of which act as cam. surfaces to guide the roller 40, is preferably formed with diametrically opposite lower limits at the sides of the cylinder 34: from which portions of the groove curve upwardly and forwardly about the cylinder to a common meeting point disposed directly at the front with reference to the presser member 12. The groove thus presents two symmetrical portions extending downwardly from the common point toward the presser member and each curving about the cylinder through approximately ninety degrees of are.

With this construction it will be evident that any turning movement of the handle 28 about its upright axis in either direction from the normal inactive position shown in Fig. 2will cause a corresponding proportional bodily downward movement thereof by virtue of the engagement of the roller a0 carried by the sleeve 32 with the cam surfaces of the cylinder 3st presented at the sides of the groove 36.

The operation of the improved machine will be clear from the preceding description. \Vi'th the presser member swung toward either side of the bed, the operator first places the die in the selected position upon the stock and then grasps the handle 28 and swings the presser member to a position above the die. By a slight turning movement of the hand which follows easily and naturally the swinging movement of the arm in bringing the presser member to position, he may then effect the downward movement of the controlling member, which serves through the described connections to trip the clutch and cause an operation of the machine; after which the controlling member may be permitted to return automatically and quickly to its normal position. The direction of turning movement of the handle which will be most feasible or natural for the operator in any case will depend upon the first position of the presser member, at one side or the other of the location of the die, and the consequent direction of movement of the arm necessary to swing it to operative position. It is important to note, further, that in the hand of an experienced operator the movement of the controlling member may be rendered, in a sense, automatic as an incident of the operation of s vinging the presser member into position. Such an operator, by grasping the handle and holding it firmly as he swings the presser member, may efiect simultaneously without conscious effort sufiicient turning movement of the handle with respect to the "presser member to finally trip the clutch at the instant when the presser member arrives at operative position above the die. For varying ranges of movement of the presser member the operator may, with practice, easily acquire suflicient skill to correlate almost unconsciously the turning movement of his hand to the extent of swinging move ment of his arm so as to effect simultaneously such a turning movement of the handle as is necessary to trip the clutch at the proper pointwith reference to the movement of the presser member.

By the expression operative position, as used herein with reference to the presser member is meant a posit-ion in which the presser member may be operated to impart pressure or deliver a blow at the required point, as for example upon a die placed in some selected position upon the stock and the expression inoperative posit-ion signifies such a position of the member that the pressure or blow would not be delivered at the point required.

It should be understood that the cylinder 34: with its cam groove and the sleeve 32 with its engaging member are to be regarded broadly as relatively movable parts and that it is practically immaterial which of these members is arranged for bodily movement with the handle. Other variations also from the precise details of structure in the illus trated preferred embodiment of the invention are within the spirit and scope of the appended claims and will be obvious to those skilled in the art to which the invention relates.
