30 Claims.

It is now quite the general practice to market belt lacer hooks on cards or holders, the hooks being spaced thereon to correspond to the desired spacing when they are applied to the belt, and also so that the card or section thereof may be used to facilitate the positioning of the hooks in the hook setting or applying machine or device. These carded hooks are commonly of uniform length, it being intended that a suitable section shall be cut therefrom to fit the particu lar belt or needs. The general practice has been to do this with shears or knives which frequently results in the mutilating of the card and displacement of the hooks thereon, thereby resulting in loss of the hooks or rendering the setting opera tions more difficult.

The main objects of this invention are:

First, to provide an improved machine for cutting belt lacer hook cards or holders.

Second, to provide means in a machine of this character for longitudinally locating the hook card or holder so that the shear blade passes through the card between adjacent hooks and is not fouled thereby.

Third, to provide a cutting machine having a vertical shear blade and ineans frictionally engaging the same so that the blade will remain in an adjusted position.

Fourth, to provide a machine of this character, having a pivoted card support with means for urging the support to its normal position and an adjustable stop for limiting the movement of the support by said resilient means.

Fifth, to provide means for effectively supporting the card while the same is being cut by the shear blade.

Sixth, to provide a cutting machine having the above desirable features, which is simple and economical in its parts and efiicient and effective in operation.

Objects relating to details and economies of my invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of a machine for cutting belt lacer hook cards, embodying the features of my invention, a card being shown in th machine in position for the cutting operation.

Fig. 2 is a fragmentary longitudinal vertical section on a line corresponding to line 22 of Figs. 4, 5 and 6.

Fig. 3 is an enlarged fragmentary section similar to Fig. 2, showing the machine in operation.

Fig. 4 is a fragmentary transverse section on a line corresponding to line 44 of Figs. 2, 3 and 6.

Fig. 5 is an enlarged fragmentary front elevation.

Fig. 6 is a fragmentary horizontal section on line 6-6 of Figs. 2 and 5, with the belt lacer hook card removed from the machine.

Fig. 7 is a view similar to Fig. 5, showing the machine in operation.

Referring to the drawings, 1 is an elongated channel1ike body member having a substantially fiat bottom web 2 and spaced vertical flanges 3. At its rear end, the body member is provided with a down-turned flange 4 from the web 2 which constitutes a rear foot. A channel-shaped standard or upright 5 is disposed at the front end of the body member, the flanges 6 of the standard overlapping the flanges of the body member and being secured thereto by means of the rivets '7. The lower end of the standard is arranged to extend below the bottom of the body member so as to provide a front supporting foot 8.

The web 9 of the standard is provided with an opening 10 for the passage of the work 11. A pair of shear plates 12 are secured to the front of the standard in upwardly diverging relation and are provided with spaced rows 13 of fine teeth, there being a groove 14 between the rows of teeth for receiving one of the carded hooks 15. The lower ends of the jaw plates 12 rest on the upper outwardly inclined edges of the plate 16 which is provided with a concave upper surface 17 registering with the concave surface 18 at the bottom of the opening 10. The plate 16 is secured to the standard 9 by means of rivets 19. The heads of the rivets 20 which secure the jaw plates 12 to the standard 9 are countersunk so as not to interfere with the downward movement of the shear blade or cutter 21 which is adapted to coast with the shear plates.

A vertical shear slideway 22 is provided at the front of the standard 5 for the shear slide 23 which is provided at its upper end with an outturned flange 24 forming a finger-piece or handle. The shear blade 21 is secured to the front of the slide 23 by means of the bolts 25, the blade depending below the slide and having downwardly converging knife edges 26. The blade is sharpened so that the back thereof presents a substantially flat surface for slidable coaction with the faces of the shear plates 12.

The web 9 of the standard has an opening 27 adjacent the slide 23, the opening having an annular recess 23 at its inner end for receiving the annular flange 29 of the cup-like spring housing 30 which is disposed in the opening. The friction disk 31 is urged into engagement with the slide 23 by the compression spring 32 arranged in the housing. The friction disk 31 acts to hold the shear slide in any desired position. The blade is thus prevented from falling inadvertently and cutting the fingers of the operator. Also, with the parts arranged in this manner, the blade remains in its upper position while the card is being manipulated. The blade guide 33 is secured to the web directly above the opening 10. The guide 33 also acts as a stop for limiting the downward movement of the slide 23.

Within the body member and at the front end thereof is disposed a work member 34 having a plurality of spaced upwardly extending transverse plates 35 which are beveled at their upper edges. The spaces 36 between the transverse plates provide slots adapted to receive the depending hooks 15 of the belt lacer holder 11 and hold the same in proper position so that the shear blade in its downward movement cuts the card between a pair of contiguous hooks, thus preventing injury to the blade and the freeing of a hook from the card or the severed portion thereof. The hook locating member 34 is secured to the web 2 by means of the rivet 37, the front end of the member abutting the inner side of the web 9.

Secured to the rear end of the web 2 of the body member are a pair of L-shaped brackets 38, the brackets being arranged in back to back spaced relation. The card support 39 pivoted at 40 is preferably of channel cross section and relatively narrow and provided at its front end with out-turned flanges 41. The flanges 41 act to support the web 42 of the card 11. In placing the card in the machine, it is manipulated so as to telescope the support 39 with the flanges 41 disposed between the in'L-urned ends 43 of the belt lacer hooks and the web 42 of the card, the support lying between the inturned ends of the hooks. Disposed between the brackets and below the support 39 is a stop for the support 39. This step is adjustably supported by the pin 45 journaled to the brackets and having an eccentric 46 supporting the stop and rotatable therein. Thus arranged, the position of the stop 44 may be adjusted by turning the pin 45 which is provided at its end with a tool receiving slot for this purpose.

The trough-like hook receiver or holder 47 is arranged under the support 39 and is provided at its rear end with inturned flanges 48 arranged in overlapping relation and provided with an opening 49 through which the card support is disposed. This arrangement has the effect of pivoting the rear end of the hook receiver to the card support at the front of the uprights 38. The hook receiver is provided with an opening 50 for the passage of the locating member 34. The front end of the hook receiver terminates at the rear of the opening 10 and the side walls thereof are turned outwardly at 51 to facilitate the insertion of the work in the machine and also to constitute projections engageable with the stops 511 at the front of the body member. The stops 511 are inturned arms of the U-shaped clips 52 which are secured to the inner sides of the flanges 6 of the standard by means of the cross bar 53 extending between said flanges and the rivets 54. The rear arms 55 of the clips 52 constitute guides for the side walls of the hook receiver 47.

A spring 56 is secured to the bottom of the body member by means of the rivet 57 and extends upwardly and forwardly under the receiver 47. The spring 56 acts to elevate the receiver from its lowermost position to disengage the hooks from the hook locating member 34. When the receiver is in its normal position, the upper end of the spring 56 is spaced therefrom as illustrated by Fig. 2.

The receiver 47 is urged upwardly by the compression spring 53 which is disposed in the spring housing 59 on the bottom of the body member. The outer end of the spring is enclosed by the cap-like plunger 60 which engages the receiver 47. The compression spring 58 not only acts to elevate the receiver, but it also acts to elevate the support 39. The upward movement of the receiver under the influence of the compression spring is limited by the stops 511 at the front end thereof, while the upward movement of the support is limited by the stop 44. By turning the pin 45, the normal position of the support 39 may be readily adjusted. The forward end of the support projects through the opening 10 and terminates in the plane of the jaw plates 12 so as to clear the blade 21 in its cutting movement. The support is held by the stop 44 in spaced relation to the top of the opening 10 so as to provide a free passage for the insertion of the web of the belt lacer hook holder therethrough.

In operation, the belt lacer hook card or holder 11 is inserted on the support 39 through the opening 10, and the same is then depressed to cause the depending hooks 15 to enter the slots 36 of the hook locating member 34 to properly position the work so that the blade will pass therethrough between a pair of the hooks, the shear plates supporting the hook adjacent the cutting point. After the work has been thus longitudinally located, the blade 21 is actuated. In its downward movement, the point of the blade first pierces the center of the web of the card and cuts the same outwardly with a slicin action. The cutting action then extends to the flanges of the card as the blade continues its downward movement and forces the same outwardly into engagement with the rows of fine teeth 13 on the jaw plates 12. The teeth support the flanges of the card while the blade severs them with a clean cut. The blade is then lifted and the spring 56 acts to elevate the hook receiver 47 so as to disengage the hooks from the hook locating member 34. The compression spring 58 elevates the receiver and the support to their upper position, in which position the belt lacer hook card may be adjusted for another cut as desired, or removed from the machine. In the cutting of the card, the flanges at the top of the forward end a of the support 39 coact with the inturned ends of the hooks to support the web of the card while being cut. The machine is adapted to cut belt lacer hook cards or holders of various sizes.

The flanges 3 of the body member have transverse openings 62 for receiving the clips 63 which secure the machine to the table or bench top 64.

I have illustrated and described my improvements in an embodiment which I have found very practical. I have not attempted to illustrate or describe other embodiments or adaptations, as it is believed this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
