THOMAS BOSTOCK, OF BROCKTON, MASSACHUSETTS, ASSIGNOR TO T. BOSTOCK AND SONS, OF BROGKTON, MASSACHUSETTS, A FIRM.
HEEL-BUILDING MACHINE.
SPECIFICATION'forming part of Letters Patent No. 772,335, dated October 18, 1904.
Application filed Jan ary 28, 1904. Serial No. 190,931. (No model.) 7
To all whmn if; may concern.-
Be it known that I, THoMAs Bos'rooK, of Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Heel-Building Machines, of which the following is aspecification.
This invention relates to heel-building machines for assembling a series of heel-lifts in proper position relatively to each other to form a heel and for holding said lifts while they are being temporarily connected, as by nails or otherwise.
The invention has for its object to provide an improved machine adapted to be adjusted to fit heel-lifts of various sizes and proportions and to act efliciently on pieced lifts which are composed or two or more sections as Well as on solid or one-part lifts.
The invention consists in the improvements, which I will now proceed to describe and claim,
Of the accompanying drawings, forming a part of this specification, Figure 1 represents a top plan view of a heel-building machine embodying my invention. Fig. 2 represents a section on line 2 2 of Fig. 1. Fig. 3 represents a section on line 3 3 of Fig. 1. Fig. 4: represents a section on line 4 4 of Fig. 1.
The same reference characters indicate the same parts in all the figures.
In the drawings, (0 represents a supporting frame or base having a bed a to support the heel-lifts 6. One of said lifts is indicated by dotted linesin Fig. l.
0 represents a fixed gage or stopprojecting above the bed at one end of the frame, said stop being formed to bear againstthe breast edges of the heel-lifts.
(Z represents a slide which is movable upon the base toward and from the stop 0, said slide being normally retracted by a spring 0?, attached at one end to the frame a and at the other end to a stud (Z connected with the slide. The slide is projected or moved forward by a chain 6;", connected at one end with the slide and at the other end with a treadle, (not shown,) said chain passing over a pulley 21*. A depression of the treadle will cause the slide d to move toward the stop 0, and the release of the treadle will permit the spring (Z' to retract the slide against an adjustablestopscrew 6.
f represents a centralaw which has aconcave front adapted to approximately lit the curvature of the rear end of a heel-lift. Said jaw has an earf, which is pivotally connected by a pin f with the forward portion of the slide 41.
g g represent levers located at opposite sides of the slide cl and pivoted at g g to the frame a, said levers being adaptedto swing in a horizontal plane.
it h represent side jaws having cars which are pivoted at h it to the forward arms of the levers said jaws being adapted to bear simultaneously on the side portions of a heellift or group of lifts when the forward arms of the levers g are swung inwardly.
i represents a wedge-block adjustably secured to the slide d and having oppositely-inclined edges i, located atvopposite sides of the slide. The wedge-block i is adjustable lengthwise of the slide (Z and is secured to the slide in any position to which it may be adjusted by a bolt 2' passing through a slot i in the wedge-block. When the bolt is turned down. its head clamps the wedge-block against the slide, and when the bolt is loosened the slot permits the wedge-block to be adjusted lengthwise of the slide. The rear arms of the levers g are provided with trundle-rolls 9 which are pressed inwardly toward the slide by a spring 1', connecting said arms. When the slide 61 is retracted, the narrower forward end of the wedge-block is between the trundle-rolls g as shown in Fig. 1 The outer .arms of the levers g and the jaws h It thereon are therefore held retracted by the spring j, which presses the trundle-rolls g against the inclined sides 2" of the wedge-.blocln hen the slide (Z is forced forward, it presses the central jaw f against the rear portion of the heel-lifts placed upon the bed, and at the same time the inclined sides of the wedge-plate force the trundle-rolls g outwardly and the jaws h h'inwardly, said jaws being thus caused to bear simultaneously against the sides of the lifts. The lifts are therefore pressed forward against the stop 0, and their side portions are compacted at the same time between the side jaws [L h;
It will be seen that the adjustable wedgeblock 2' enables the extent of inward movement imparted to the side jaws it to be varied, so that variations in the width of the heellifts may be compensated for. Thus if the machine is adjusted for a heel of a given length and width and is required to act on a heel whose length is the same but whose width is increased the wedge-block 2' will be given a backward adjustment to decrease the extent of inward movement of the side jaws it. If a heel of the same length but of a decreased width is to be treated, the wedge-block will be given a forward adjustment. Provision is thus made for all variations between the length and width of different heels.
The machine is particularly adapted for building pieced lifts, because of the fact that the jaws act on both the sides and the rear ends of the lifts.
I claim 1. A heel-building machine comprising a bed or support, a fixed gage or stop at one heel-lift and force the same against the stop,
pivoted levers located at opposite sides of said slide, side jaws carried by the forward arms of the levers, and a wedge carried by the slide and interposed between the rear arms of the levers.
2. A heel-building machine comprising a bed or support, a fixed gage or stop at one end of the bed, a slide or carrier movable toward and from said stop and carrying a central jaw adapted to engage the rear end of a heel-lift and force the same against the stop, pivoted levers located at opposite sides of said slide, side jaws carried by the forward arms of the levers, a wedge mounted on the slide and adjustable lengthwise thereof, and means for securing the wedge to the slide in different positions, the wedge being interposed between the rear arms of the levers.
In testimony whereof I have affixed my signature in presence of two witnesses.
