Application filed May ig. 3 is a detail sectional View a the line 3-3 of Fig. 1., Fig. t is a plan view of the breasting knife holder, Fig. 5 1s a front view To all'who'm it may concern;

Be it known that l, l lnwnv A. Wnns'rnn, of Grovcland, county of Essex,

State of in whicmi ig. 21 as a side elevation therecr, l c is provided with an Massachusetts, have invented an lmprovcthereof, Fig. 6 is a sectional View onthe line ment'in Heel-Breasting Machines, of which 6-43 of Fig. 5, Fig. 7 is a detail front view to the following is a specification. of the heel holding device, and Fig. 8 is a In heel breasting machines in which a stadetail front elevation of a modified form 0 tionary breasting knife is employed, or in i heel holder, Fig. 9 is a plan view thereof which the knife is only moved transversely and, Fig. 10 is a sectional view, at the line 10 of its edge, or vertically downward, to per- 1010 of Fig. 8, showing the connection form the breasting operation, much difficulty with the adjacent portion of the machine.

' is occasioned, particularly in breasting high 1 Asshown in the drawings, the base a, is heels,- on account of the fact that thcknife provided with a main driving shaft 1), which willialmost invariably be deflected, or yield, is adapted to drive a main operating she 15 to an extent, varying with the conditions, a, vertically mounted in the head a, by 79 so that the breasted surface will not he means of suitable power transmitted by bolts straight, out will have a wavy appearance. and pulleys. This is objectionable, as additional labor in fhe head a is provided with horizontal. finishing is necessitated to straighten the guideways a opening to the front side 0 ZO surface. This difficulty may be entirely the machine, and a hnife-block-holder cl is "avoided by causing the knife to vibrate or rclnovably mounted in said guideways, suit reciprocate longitudinally of its edge, so that able means for locking said holder therein it markesa drawing out asthe heel is moved being provided, as screws :0, having portions against it, but it is frequently necessary to of the heads thereof cutaway at one side.

the heel being maintained by the spring 112. W hen the operation is finished and the jack lowered, the carrier j will also be lowered against the stop 11..

In case it is desired to employ a knife having a different curvature, the holder cl will be unlocked and withdrawn from the guideways in which it is held, and another block of similar construction, but having a cam path curved on a different radius, and a different knife bloc-k provided With a breasting knife curved on said radius, will be inserted, the block 2', being readily disengaged from the block 6, as holder (Z is withdrawn, and the corres o'nding parts being re'engaged when inserted.

In Figs. 8, 5) and 10 I show a modified form of heel holding means which is espe cially desirable when heels having concave sides, so that the top lift is of greater width than some of the intermediate lifts, are to be breasted. In this form of my invention, a frame .5 is rigidly secured, at a suitable elevation, to the under side of the head by suitable means, as by adjustably mounting it on the guide rods 7., before described. Said frame a is provided with a pair of horizontal slots 8 in which a pair of blocks f are slidably mounted. A screw 7), similar to the screw 1), already described, is connected to said blocks 1, by means of right and left threads, and is held from longitudinal movement with relation to the frame a by means of a swivel connection therewith, provided by a bracket a mounted thereon. A pair of right-angular shaped, or bellcrank levers u are respectively mounted on pivots 2f"secured in blocks a, with the arms 1/ thereof dependingfrom said pivots Z, and the arms u thereof extending toward each other, and overlapping, as shown. The arms 7/ are each provided with longitudinal slots n" which extend from the ends of said arms toward the pivot thereof for a suitable distance. and a block 21 is mounted to slide vertically in a slot 8 in the frame, said block having a bolt '11, mounted therein, on which a pair of rectangular shaped blocks .ower end, which is rotatably mounted in, and connected to the bearing block 17, so that when the shaft 0 is rotated the knife block a will be reciprocated.

A carrier j is mounted toslide on a pair which are secured on the under side of the head a short distance in the rear of, and at opposite sides of the breasting knife, and a rod Z, is also mounted in the head in a position parallel to aid rods X and is adapted to extend through a rcarwardly extending bracket 7", on the rear side of the carrier j. A spring,- m, is mounted on the rod -Z, between the head and the upper end of the bracket j, and a stop nut 11, is mounted on the lower end of said rod Z, said nut acting to support the carrier and limit the downward movement thereof. he carrier j, is provided with a longitudinal slot 5)", which extends therethrough and in which a pair of dogs 0 are slidably mounted, and an adjusting screw, 72, having a swivel connection with a bracket g on the carrier, extends through said dogs 0 and is provided with right and leftscrew threads, which respectively engage the same, so that when said screw is turned in one direction said dogs will be simultaneously moved toward each other, and when turned in the opposite direction, will be simultaneously moved away from each other.

Each block 0 is provided with a depending finger 0, having hcel engaging faces 0 at their adjacent sides, which are arranged to diverge to a slight extent as they extend down ardly. A jack r is mount d on a vertically movable table'r', which is adapted to be lifted by a suitable treadle mechanism connected thereto, as shown in Fig. 2, so that when said treadle is depressed, said jack will be lifted toward the breasting knife, and adjustable stop r-, being provided to limit the upward movement of the jack, such movement of ti. v jack toward and from the breasting-knife being-herein referred to as transversely of the knife edge.

In operation, the breasting knife is caused to reciprocate rapidly longitudinally of its edge. The shoe is placed on the jack '2", and, as it is lifted, the fingers 0 will engage the sides of the heel, at its top, so that 1 respectively arranged in the slots u so that they may slide therein. A spring 2,'is connor-ted to the upper end of the block W, and to the brz cket a and acts to draw said block u n'vardly, and thereby to swing the arms 1/ to ardi each other. Said arms u are prog in their ends.

it will become firmly wedged between the diverging faces thereof. As the jack is lifted farther, the breastportion of the] heel [will be brought into engagement .with the knife, so that the heel will be. breasted in a manner which will be obvious, and, as the jack is lifted to perform this operation, 1 the carrier will belifted thereby, so that the relative positions of the shoe and the holder will be maintained and the heel will be firmly held against lateral movement during the entire breasting operation, a rm engagement between the holder and vidcd with friction rolls mounted to rotate on pivots which extend parallcll to the pivots t, as shown, the centers-of said rolls being held approximately at, or slightly above, the level of the edge of the breasting knife f. With this construction,'when'the block 1' moved upwardly, the rolls 1 will be simultaneously swung toward each othe and whenit is moved down they will likewise be swung apart, but in all w are pivotally mounted, said blocks being I senses positions thereof they will be held equidisl jack and means permitting adjustment of the vertical plane in which the axis of the blocks w constantly lies. 4 The jack is also arranged so that the rental vertical plane thereof is coincident with said vertical plane of said axis.

By turning the adjusting screw 7) the blocks t may be simultaneously adjusted either toward or from the central vertical plane of the axis of blocks 10, or the middle of the jack, so that the levers u Will be correspondingly adjusted, This adjustment should be such that, when the jack is raised, the edge of the top lift of the heel to be breasted will engage the, rolls 3 between the vertical planes of the axes thereof, so that the levers u will be forced away from each other and the rolls will be permitted. to roll down on the sides of the heel, the spring 2 actingt'o hold the rolls firmly against the sides of the heel in all the vertical positions thereof.

tant from cated the tendency ofthe knife to pull the heel laterally will be effectively resisted by the spring 2, acting through the parts which directly engage the heel. With this arrangement, it will not be possible for either roll to move to greaterdistance from the central line than the other, so that the heel Will at all times be centrally held with relation to the breasting knife.
