To all whom it may concern:

Be it known that 1, JOHN Vinson TIER- NEY, a citizen of the United States of America,-resid ing at Ashtree, Beulah I-Iill, Upper Norwood, in the county of London, England, have invented certain new and useful Improvements in Apparatus for Hammering the Heels of Boots and Shoes, of which the following is a specification.

This invention relates to apparatus for hammering the edges of the lifts and top pieces of the heels of boots and shoes, and partly to that type of apparatus in which the boot or shoe is carried by a support that is capable of being moved toward or away from a power driven hammer arranged to deliver blows in rapid succession upon the part-of the heel to be hammered.

According to this invention I employ a pneumatic or other power hammer of the rectilinear reciprocating type and mount the hammering tool in a fixed guide or socket in such a manner as to be acted upon by the piston of the hammer. This action is preferably arranged to take place automatically when the boot or shoe is pressed against the hammering tool or. against guides supported in front of such tool, and to be automatically discontinued when the said pressure is removed. For'this purpose the hammer may be mounted upon a fixed head-and the boot or shoe upon a support connected with the hammer and adapted to be moved toward and away therefrom, or the hammer together with the aforesaid guides may be mounted upona'movable head capable of being moved toward and away from a fixed point for putting the hammer into and out of operation. This can also be performed by means of a treadle placed within suitable reach of the operator. In order that the said invention may be clearly understood and readily carried into effect I will describe the same more fully -'with reference to the accompanying drawings, in which Figure 1 is a side elevation part of which is shown in section of a heel hammering machine constructed in accordance with this invention. Flg. 2 1s a similar view showing afslightly modified arrangement, and

Fig. 3 is a section taken on line A-'B of Fig. 2. Fig. 4 is a 'front elevation of a is a side elevation of Fig. 4. Fig. 6 is a plan of the hammer. Fig. 7 is a plan Fig. 5

partly shown in section of the machine, head drawn to a larger scale. Fig. 8 is a front elevation partly shown in section of Fig. 7. Fig. 9 is a side elevation of Fig. with the right hand adjusting nut removed for the sake of clearness. Fig. 10 is a plan partly shown in section of a modified construction of a machine head. Fig. 11. is a detached view of the right hand guide shown in Fig. 10.

In the example shown in Figs. 1 to 3 the hammering tool C ton of a pneumatic hammer that ,is situated in the cylinder 0 in the ordinary way, such hammering tool being mounted in a fixed guide or socket c". The cylinder 0 is supported upon a pedestal or column 0 and is supplied with air through a pipe 0 The boot or shoe A is supported upon a last a that is rotatably mounted upon a holding device a. This holding device is rotatably mounted in a table 6 and is advantageously cranked at a somewhat in the manner indicated in order to permit of the necessary movements being imparted to the boot heel to enable the hammering operation to be satisfactorily effected. The table I) is formed on its under side with a threaded boss Z) which engages with a threaded socket formed in the top of the pillar B. This arrangement enables the position of the boot to be adjusted in a vertical direction in relation to the hammering tool C by rotating the table I) in one direction or the other. a clamping screw If securing the table in position after adjustn'lent. The pillar B is pivoted at its lower end to the column a and when the machine is in its operative condition such pillar is drawn toward the hammering tool C through the intervention of a weight suspended from an arm b that projectstrom the pillar B. The latter, 'sretained in its outwardposiman to the hammering tool 0 when the machine is in its inoperative condition by a catch 0 pivoted to the column 0 and adapted to engage with a pin on the pillar B when the latter has been moved to a predetermined extent away from the hammering tool. The catch 0 is connected by a rod'c to a spring controlled treadle lever c which disengages the catch i: om the pin 6 when the treadle is depressed.

. In order to cause the hammer to be automatically put into or out of operation by moving the heel of the boot or shoe into or out of engagement with the hammering tool, the hammer is provided with a suitable valve adapted normally to assume a closed condition. This valve is provided with an actuating stem 0 which rests upon one arm of a bell crank lever c pivoted to the column 0. The other arm of this lever rests against the end of a rod 0 that is slidably mounted in the column 0' in line with an- 10 other slidablv mounted rod that is separated from the rod 0* by spring 0 interposed between collars c and on the rods 0 and 0 respectively. hen the treadle c is depressed the weight actuates the pillar 15 B to bring the heel of the boot or shoe into contact with the hammering tool C, the pillar B previously coming into contact with the rod 0 and imparting endwise movement to the rod 0 through. the spring 0 with the result that the aforesaid valve is opened and the hammer put into operation. The spring 0" is made short enough not to operate the rod 0 until the rod a is moved forward by the pillar '13 almost into contact with the 5 rod 0 the valve stein 0 and crank lever 0 returning the rod 0 when the forward pressure of the spring 0 is relieved. The boot or shoe is now turned around by hand upon the table 7) and moved sidewise when nec- 0 essary to bring all the parts of the edges of the lifts and top piece of the heel to be hammered into contact with the hammering tool. This sidcwise movement is permitted in the example now under consideration by the cranked portion of the holding device a lVhen the hammering operation is com pleted the pillar B is withdrawn from the hammering tool until the catch 0 engages with the pin b and retains the pillar in its 40 outward. position, the air valve previously having closed by reason of the disengagement of the pillar with the rod 0".

In the modified arrangement illustrated in Figs. 2 and 3 a fiat spring blade is substituted for the tubular pillar comprising at is'conveniently secured at its lower 'end to a bracket Z) pivoted tothe base of the column 0 and carries at its upper end the threaded socket b for supporting the adjustable "table 6. In this example the catch 0 is pivoted' on a pin 0 extending through the pillar c and provided with distance pieces 0 as shown in Fig. 3, to retain such catch in a central position in relation to the pillar. A further modification consists in supporting the pin b upon a clamp bwhich can be fixed in any required position upon the spring blade for causing the latter to occupy a position closer to or farther away from t e hammering tool C, when the catch a is in engagement with the pin Z). A single rod a is employed for actuating the bell crank lever 0 and the latter is connected to the valve rod 0 through the intervention of a link 0 the spring 0 being interposed between the threaded socket b -and a collar 0 on the rod 0 The hammering tool C may be driven by any suitable pressure fluid, or by electrical or mechanical means, the end of the hammering tool may be spherical as shown in Fig. 1, or convex as shown in Fig. 2 or be otherwise shaped to suit any particular requirements. If desired a spring may be substituted for the weight shown in Fig. 1, and a cam, eccentric, or toggle arrangement worked by a hand lever or treadle for retaining the pillar B in its outward position may be substituted for the catch 0 Means may also be provided for varying the angular position of the table I) in relation to the axis of the pillar B in addition to the means for effecting its vertical adjustment. For example the table b may be hinged to the screwed shank b and be secured in any adjusted position by a suitable clamping device.

In the example shown in Figs. t-to 9 the boot heel is supported upon an adjustable rest D that is situated between and below -two guides E, E situated on opposite sides of the hammer and adapted respectively to" engage with the lower edge of the heel and the portion of the boot upper that comes immediately above the heel. The rest D is mounted on the threaded rod 03 and'secured in vertical adjustment by the nuts 0?. The

nut (Z serves to hold it in angular adjust ment on the end of the rod d. The hammer.. c, the rest 1) and the guides E, are mounted upon aheadF that is fixedto an upright arm Figs. 4 and 5, pivoted ,iatits lower end to a frame or pillarG and .havmg.

its outward movement fromthe pillar pong trolled by a suitable stop, such for example; a slot f In the as a bolt f passing through pivoted arm 1 and secured in an upwardly extending portion 9 of the aforesaid frame or pillar G. The hammering tool G is as. already mentioned -slidably mounted, in a guide 0* carried by the head and the hammer is provided with a spring controlled plunger 0 adapted to be depressed by 0on tact with the upwardly extending portion gr of the frame or pillar G when. the head is advanced thereto.

This plunger may constitute the stem of a valve which controls the supply of air to ortrom. the hammer. The aforesaid guides E E project from spindles e which are slidably mounted in brackets e" and are conveniently provided with an adjusting screw 6' by means of which they can be caused to occupy a position that is more or less in advance of the hammering tool according to requirements. These guides are also capable of adjustment in a direction toward and away from each other to accommodate heels of different thickness. In the example shown such adjustment is effected by providing the said brackets 0* with screwed spindles 6 supported in bearings 6 carried by the head F and arranged to receive an axial movement through the intervention of nuts 6 mounted between the bearings upon screwed portions of such spindles. These nuts are prevented from being rotated through the' vibration of the machine by means of spring controlled plungers e which bear againstroughened or otherwise suitably formed peripheral portions of the nuts. Angular or rotary motion of the spindles is prevented by keys e clamped by bolts 6 between lugs c" on the bearings e and engaging with slots 6 formed in the said spindles. The guides E E are in like manner prevented from rotary or angular motion by keys 6 clamped between lugs c on the brackets e and engaging with slots e in the guide spindles 0. In the modification described, slight pressure of the boot heel against the aforesaid guides depresses the plunger c against the upwardly extending portion of the frame or pillar G with the result that the hammer is set in motion and continues to operate upon the heel until the said pressure is removed.

In the example shown in Fig. 10, the guides E E are normally retained slightly in advance of the hammering tool (1 by springs a situated in the brackets c and capable of adjustment by set screws (1, and the brackets c are secured in their adjusted positions by set screws a. Fig. 11 is a side elevation of the guide spindle c that carries the guide E.

If desired the head F may be mounted upon a fixed frame or pillar, and the valve which controls the supply of air to the hammer may be connected with a trcadie placed within cmizvcnient reach of the operator.
