Patented Jan. 16, 1940 PATENT I OFFICE CLICKING MACHINE Euclid 1. La Chapelle, Brockton, Mass, assignor to United Shoe Machinery Corporation,- Borough of Flemington, N. Jersey .I., a corporation of New Application February 21, 1938, Serial No. 191,630

4 Claims.

This invention relates to machines for operating upon sheet material and is; herein illustrated as embodied in a clicking machine of the type illustrated'in United States Letters Patent No. 1,068,455, granted July 29, 1913, upon an application filed in the name of A. R. Schoenky.

In cutting blanks such as shoe part blanks from sheet material it is common practice to make use of a click-machine provided with a wood or fiber cutting block and to use as cutting tools dies having comparatively sharp edges. Such dies penetrate slightly into the cutting block and consequently eventually become dulled and require sharpening. Some use has been made of machines provided with metal cutting blocks in which case blunt dies which require little or no sharpening can be used with good results. However, blunt edged dies cannot be used satisfactorily in the cutting of fabrics or certain types of upper leathers such as suede.

In view of the foregoing, it is an object of the invention to provide an improved clicking machine especially adapted for use with either sharp or blunt edged dies in cutting blanks from sheet material. To this end and as illustrated, I have provided a clicking machine having a frame, a cutting block carried by the frame, and a removable auxiliary cutting block resiliently carried by the frame in spaced relation to the first-mentioned cutting block, together with a presser arm selectively cooperable with either of the blocks to force dies through sheet material positioned thereon, thereby to form blanks. The auxiliary block is preferably of metal and is adapted for use with comparatively blunt dies in cutting blanks from leather and similar materials wherev as the other block is preferably made of wood or disclosed in the following specification and in' the accompanying drawing and are pointed out in the appended claims.

In the drawing: Fig. 1 is a view inside elevation of a clicking machine embodying my invention;

Fig. 2 is a view in front elevation of a portion of the machine;

Fig. 3 is a view partly in section of details of the cutting blocks and supporting structure;

Fig. 4 is a detail view partly in section of a portion of the device for adjusting the presser arm w As shown in Fig. 1, the machine comprises a frame 0 having a bed or support l2 and a spindle l4 carrying a presser arm I6 arranged for movement with the spindle laterally across the bed l2 and movable heightwise thereof and performing pressure-applying operations upon dies positioned upon material located upon a cutting block l8 carried by the bed l2. The cutting block I8 is preferably of wood and other fibrous material and is well adapted for use in forming blanks with the aid of sharp edged dies such as the die 20 shown in Figs. 5 and 6 from sheet material such as canvas and other fabrics as well as substantially all types of upper leathers.

In order to provide a cutting surface which can be used with blunt dies such as the die 22, shown in Figs. 7 and 8, for cutting blanks from materials such as most upper leathers the machine is provided with a metal cutting block 24 supported on vertical rods 26 extending through openings 28 in bosses 30 carried by the bed l2. The upper ends of the rods are provided with recesses 32 arranged to receive shouldered pins 34 secured to the metal block 24 by screw threads 35. The pins 34 engage the recesses 32 with a sliding fit such that the block 24 can readily be removed from the rods 26 by elevating it slightly. The block 24 is normally spaced a slight distance above the upper surface of the cutting block l8 and is yieldingly supported against thrust of the presser member It by springs 38 which surround the rods 26 and extend between the upper surfaces of the bosses 30 to shoulders 40. This construction provides a sufficient yield of the block 24 in a downward direction during the cutting operation to prevent breakage of dies between the comparatively unyielding surfaces of the presser arm l6 and the surface of the block 24,

Preferably, the block 24 comprises a plate 42 (Fig. 3) of cast iron or steel and carries a replaceable cutting plate 44 of tempered steel.

In view of the fact that cutting dies used in the machine are substantially the same height it is desirable to adjust the presser arm l6 heightwise of the spindle l4 when the cutting block to be used is changed. To this end the presser arm is provided with a split collar 46 which surrounds the spindle l4 and is clamped thereto by screw bolts 48. The spindle is provided with screw threads 50 which carry a nut 52 adapted to engage the lower portion of the collar 46 and to adjust the presser arm heightwise of the machine when the bolts 48 are loosened. When this adjustment is being made, in order to prevent turning of the spindle M with the nut as the nut is rotated, there is a hand screw 54 adapted to enter a slot 56 in the spindle to hold the latter stationary.

In the operation of the machine with the cutting block 24 in its normal position, as shown in Figs. 1, 2 and 3, dull edged dies are placed upon material positioned upon the block and the presser arm is operated to force such dies through the material into contact with the block which yields slightly as the springs 38 are compressed. When it is desired to make use of sharp edged dies the cutting block 24 is removed from the vertical supports 26 and after lowering the presser arm It by means of the nut 52 the spaced upper surface of the Wooden cutting block I8 becomes the cutting surface for the material. Thus it should be apparent that I have provided a comparatively simple mechanism by which a clicking machine is adapted for use in cutting sheet material with either sharp dies or blunt edged dies.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A clicking machine comprising a frame, a cutting block carried by the frame, a presser member mounted upon the frame for movement laterally across the block and heightwise thereof, and an auxiliary cutting block removably mounted upon the frame and spaced in a heightwise direction from the first-mentioned cutting block.

2. A clicking machine comprising a frame, a bed carried by the frame, a presser member mounted in the frame for movement laterally across the bed and heightwise thereof, a plurality of rods resiliently mounted upon the frame adjacent to the bed, and a cutting block removably mounted upon the upper ends of the rods.

3. A clicking machine comprising a frame, a wooden cutting block carried by the frame, a metal cutting block spaced from the wooden cutting block and resiliently mounted upon the frame, and a presser arm movable laterally of and heightwise of the frame and cooperable selectively with either of the cutting blocks to produce pressure-applying operations upon work positioned thereon.

4. A clicking machine comprising a frame, a cutting block mounted in the frame, a plurality of rods extending heightwise of the frame and adjacent to the cutting block, an auxiliary cutting block mounted upon the ends of the rods in spaced relation to the first-mentioned cutting block, and a presser arm selectively cooperable with either of the cutting blocks for producing pressure applying operations upon material positioned thereon.
