ARTHUR BATES, OF LEICES'IER, ENGLAND, ASSIGNOR T0 UNITED SHOE MACHINERY COMPANY, OF'PA'IERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

HEEL-BREASTING MACHINE.

Application led July 7, 1910.

To all whom t may concern:

Be it known that I, ARTHUR BATES, a subject of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in Heel-Breasting 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 iigures.

This invention relates to machinery for use in the manufacture of boots and shoes and particularly to machines having tools which are power operated to do their work. The invention may with advantage be applied to machines having reciprocating cutting or shaping tools and is herein shown and described by way of exemplification as applied to a machine for breasting the heels of boots and shoes. It is usual, in heel breasting machines, to provide a tread plate which is brought into contact with the tread face of the heel and is so positioned that its forward edge indicates the line upon which the knife will cut. In some cases, however, the breast edge of the top lift is trimmed to its final shape and the heel ispositioned with the edge of the top lift in coincidence with the edge of the tread plate.

A n object of the present invention is to provide means whereby the knife itself may be manipulated to serve as a gage for positioning the shoe, thus doing away with the tread plate and its operating mechanism, and to otherwise simplify and expedite the operation of breasting heels.

As a feature of the invention the knife may be lowered, preferably manually, into proximity to the tread face of the heel. or against the breast face of the top lift so as to serve as a guide for positioning the heel, the knife being subsequently actuated, preferably by power, to effect the operation of breasting the heel.

As a further feature of the invention, the knife, after being positioned against the tread face of the heel or against the breast face of the top lift, is further pressed manually against the heel and the resistance offered to the knife by the heel serves to bring the power-actuated mechanism automatically into operation for breasting a heel. As I am advised, it is new in a breasting or other shoe machine having power op- Speccation of Letters Patent.

Serial No. 570,770.

erating means for a tool to provide manual means by which the tool may be moved in the direction of its operative stroke and into proximity to the surface to be operated upon and which operating means is arranged to effect thereupon an operative connection of the power mechanism to the tool for causing the tool to do its work. Preferably and as herein shown, the knife positioning means comprises a .lever which serves first to lower the knife into position against or in front of the top lift of the heel and when the knife is stopped by contact with the heel or with the unbreasted portion thereof the lever may, by a change of fulcrum, be further actuated to effect the tripping of a clutch which connects the knife to its power actuating mechanism.

These and other features of the invention will appear more fully from the following detailed description, when read i-n connection with the accompanying drawings, and will be pointed out in the appended claims.

The knife clamping mechanism herein shown and described but not claimed is made the subject-matter of a separate copending application Serial No. 582,703, filed September 19, 1910.

In the drawings,-Figure l is a side elevation, partly in section, of the upper p0rtion of a power heel breasting machine embodying my invention; Fig. Q is a fragmentary detail in front elevation of the work support; Fig. 3 is a plan view of the machine; Fig. et is a horizontal section through the knife clamp on the line of Fig.y l; Fig. 5 is a fragmentary sectional plan on the line 5-5 of Fig. 6; and Fig. 6 is a vertical section of the lower portion of the machine taken on the line 6 6 of Fig. 5.

In the drawings, the numeral 1 indicates the frame of the machine which may be of rectangular horizontal section and has vertical slideways 2 formed on the inner upright faces of its sides to receive a sliding head 3 which carries a suitable operating tool, such, for example, as the heel breasting knife 4.

Suitable means is provided for suspending the knife normally in an elevated position out of contact with the work and as one convenient means for this purpose springs 6 are secured to the slide near its lower end as at 7 and at the upper end to bolts` 8 which y `mounted on the head 3 for vertical reciprocation, is moved manually by hand lever 30, Fig. l, into proximity to the top lift of the heel bcingbreasted so that the knife will serve as a gage for positioning the heel and knife relatively to each other prior to the completion of the knife stroke to breast the heel. The lever 30 engages the forked upper end of a plunger 31 which is seated for free sliding /movement in an elongated recess inl the knife carrying slide 3, as shown. This construction permits downward actuation of the slide 3 byv power independently of the plunger 31 and thus the transmission of dangerous shocks to the operator through the hand lever 30 is avoided.

'The end of the lever 30, which forms the fulcrum during the operation of lowering the knife, is pivoted at 3Q, Fig. to a rod 34, Fig. 6, which is connected with mechanism for controlling the power actuation of the knife. As shown in F ig. 3, the end of the lever 30 is forked at 35 and is pivotally connected to the upper end of the controlling rod 34 by a pin 36.

Power is transmitted to the slide 3 through a connecting rod or link 40 which passes through a boss 44 on the rear face of the slide 3. The rod 40 is a loose lit in the boss 44 in order that the slide 3 may be lowered manually by the handle 30. Upon downward movement of the rod 40, however, the Washer 45 and nuts 46 engage the upper face of the boss 44 and actuate the knife to complete its stroke.

The lower end of the rod 40 is formed with a boss 75 rwhich engages the crank 50 which is driven from the main shaft 51 througha suitable clutch 53. Any suitable form of one-revolution clutch may be employed. The clutch shown is of the wellknown roller type and comprises a member 54 which, when held from rotation by contact of the shoulder 58 with the horseshoe-shaped spring 57 upon the stop arm 55, permits free rotation of the shaft 51. The arm 55 is mounted upon the rock-shaft 56 which also carries an arm 63 between the end of which and the frame is secured a spring 60 which holds the stop arm 55 normally in position to engage the shoulder 58 on the clutch member 54. The clutch is, of course, thrown in and the machine actuated when the arm 55 is moved out of engagement with the shoulder 58. To effect this an arm is loosely pivoted on the rockshaft 56 and at its opposite end is forked to provide bearings for a pin 38 through which passes the rod 34, the rod being adjustably held in the pin 38 by a set screw 380. The arm 70 has adjustably secured thereto by a screw 72 a laterally projecting plate 71, which, in the normal or inoperative position ofthe clutch, is located beneath a similar plate 68 secured by a screw 69 to the lower arm 8O of an elbow lever 81 which has a pivoted pin 83 held therein by a set screw 82 Vand freely movable in a bearing 7 7 in the forked end 7 8 of the lever 63. rlhe upper arm 7 4 of the lever 8l lies in the path of movement of the boss 75. The spring 60 is shown as secured to the frame at 61 and is preferably connected to the arm 63 by a hook 62 on the elbow lever 81 so that the spring 60 not only tends to hold the arm 55 beneath the shoulder 58 as described, but also tends to move the elbow lever counter-clockwise, Fig. 6, so that the plate 68 is held in position to engage the plate 71 on the arm 70.` lt will now .be apparent that when the arm 70 is swung upwardly by a pull on the rod 34, the plate T1 will, by contact with the plate 69, raise the arm 63 against the spring 60 and by rotation of the rock-shaft 56 will swing the arm 55 from under the shoulder 58 whereupon the clutch `will take hold and the crank 50 will be rotated to operate the knife. At a suitable time in the rotation of the crank the boss comes in contact with the arm 74 of the elbow lever 81 and depresses it sufficiently to move the plate 68 out of contact with the plate 71 whereupon the springv 60 acts to swing the arm 55 back into position to engage the shoulder 58 and throw out the clutch. `When the rod 34 and the arm '70 are again lowered, the plate 68 snaps into position over the plate 71, the parts having then resumed normal position ready for further operation. T o limit the movement of the arm 63, an adjustable stop 64 lis provided which coperates with a stationary stop 65.

The work support shown comprises a block 2,0 which is held between side members 29. The side members have segmental flanges on their lower edges which engage undercut grooves 21 in the sleeve 24. Clamping bolts 9.00 are provided which act to cla-mp the block Q0 between the side members 29 and also to clamp the flanges on the side members in the grooves 21. The sleeve 24 is mounted in a bracket 22 secured to the frame at 23. The bracket 2Q- has a slit 26, a clamp screw 27 being provided to spring the bracket into clamping engagement with the sleeve 24. A pin 28 on the sleeve 24 lies in the slit 26 and prevents rotation of the sleeve. Within the sleeve 24 is a post 201 which is mounted for rotation upon a suitable supporting rod 207 and is provided with a hand wheel 206. The upper end of the post 201 has threaded engagement at 202 with a stem 203 of a head 204; which enters an arcuate slot or groove in the undei side of the block 20. By this construction, when the clamping bolts 200 are loosened, the hand wheel 206 may be operated to adjust the block 20 vertically while the seg mental grooves 21 permit its being adjusted angularly, and when the bolts 200 are tightened the block is held firmly in adjusted position.

it is to be observed that the axis of tilting movement of the cutting block 20 lies approximately at its surface and in the plane of the operative movement of the knife, so that the block is always presented under the knife and thus injury to the edge of the knife is avoided which might otherwise result from its accidental contact with the metal part of the work support. iVhen the surface of the block 20 has been marred to such an extent that it must be eut down to a fresh surface, the block 20 can be set up to normal position independently of the sleeve 24 by loosening the bolts 200 and turning the hand wheel 206 as described. A novel knife clamp is also shown which will enable knives of various formation to be secured very firmly to the slide. The knife holding arm 90, Fig. d, of the slide is provided with movable abutments 91, shown as semi-cylindrical in shape, which are seated in recesses 92. The abutments 91 are preferably hollowed out so that each has two areas of contact with the back of the knife, one on each side of the axis about which the abut` ments are mounted to rotate so that the abut-ments can readily adjust themselves to variations in the contour of the backs of the knives. lFlanges 93 near the upper and lower ends of the abutments prevent their` longitudinal displacement and the knife is held in place against them by a. clamping plate 911 having projections 96 located preferably opposite to the axes of the abutments. Threaded studs 95 serve as means for clamping the knife between the projections 96 and the abutments 91. Screws 97 are provided to take the thrust of the knife and to furnish means for adjusting the knife longitudinally.

In the operation of the machine the heel is placed upon the work support 20 and the handle 30 is drawn downwardly. Owing to the friction of the stop arm 55 with the stop shoulder 58, the friction of other related parts and the pull of the spring 60, the rod 34 remains stationary and the handle 30 first fulcrums about its connection with the rod 3A and consequently moves the slide downwardly and with it the knife #l until the knife is opposite to the breast of the top lift ofthe heel. During this movement the boss 4:4 has slid downwardly on the rod 40. The heel is now positioned with the breast face of the top lift against the back of the knife and the handle 30, being further actuated, brings the knife edge into engagement with the unbreasted portion of the heel. Theknife being unable to descend farther, because of the resistance offered by the heel, further movement of the lever 30 in the same direction causes its fulcrum to change from the pivot 36 to the pivot 31 and the rod 3st to move upwardly, carrying with it the arm T0 and tripping the clutch in the manner described. The clutch being thrown in, the crank 50 rotates, moving the connecting rod 40 downwardly until the nuts 46 engage the boss 111i and actuate the knife to do its work, whereupon the clutch is thrown out in the manner described and the machine comes to rest. The knife and knife carrier are drawn back to their elevated position by the springs 6.

It is understood, of course, that while the invention is shown as applied to a machine for breasting heels before they are attached to the shoe, the machine is equally well adapted for breasting heels after they have been attached; nor is the invention limited in its construction or application except as necessitated by the claims when construed in the light of the prior art.
