To all whom it may concern:

Be it known that we, WALTER JACKSON and HAROLD NICHOLS POCI-IIN, subjects of the King of Great Britain, trading together as JAoKsoN & POCHIN, residing at Leicester, in the county of Leicester, England, have invented certain new and useful Improvements in Finishing-Machines for Boots and Shoes, of which the following is a specification.

This invention relates to machinery employed in the manufacture of boots and refers more particularly to what are known as edge-setting machines for finishing the edges of the soles as is well understood.

The object of the invention is to produce an improved machine in which the work is automatically presented to the finishing or edge-setting tool. j

The jack or work support for the boot is carried in the upper end of a vertical rod driven by worm gearing from a shaft provided with pulleys and an improved arrangement of clutches, one pair of which when in gear drive the shaft, and the work support in one direction, and the other pair when in gear drive the said shaft and work support in the opposite direction. A shipper lever is located between the two pairs of pulleys and clutches to simultaneously move the clutches into and out of contact, and an arrangement of cams on the underside of a table carried by the jack rod acts on the shipper lever and causes the latter to change the clutches and thus reverse the motion of the jack.

The edge setting tool is of the vibrating type carried on a rapidly oscillating arm actuated from an eccentric or crank on a shaft in the head of the machine in the well known manner. The said shaft however is flexibly driven from the main shaft of the machine, and the edge-setting iron or tool is held in such a manner that it is free to adjust its position as required by the sole edge of the boot.

The head in which the tool and its osci1- lating arm are carried is mounted on a slide bed so as to be able to move to and fro relatively to the boot as required. The slide bed is mounted on an attached bracket and is connected thereto by a joint and vertical pin, and counterweights are arranged so that the tool is always maintained in contact with the edge of the sole. In order to keep the tool always square and parallel with the sole edge, a cam or templet on a table on the jack rod is provided, the said cam being of a contour to coincide with the shape of the sole, and a roll on the end of an arm projecting from the tool head is arranged to move in contact therewith to efl'oct this resalt, the head being pivoted as previously mentioned so that it can move in a horizontal plane coincidentally with the jack and independently of the bracket on which the head and slide bed are supported.

The invention will however be more clearly understood from the following further description with reference to the accompanying drawings, in which Figure 1, is a side elevation of an edge setting machine constructed according to this invention. Fig. 2, is a plan of the upperportion of the machine. Fig. 3, shows the same parts as illustrated in Fig. 2, the jack being moved around to a different position. Fi 4, is a side elevation of the tool per se, and tool holder. Fig. 5, is a plan of the said two parts. Figs. 4: and 5 are drawn to a larger scale and like parts are designated by like reference characters in all the figures.

Referring to Fig. 1, 2 represents the main frame or stand of the machine supporting at the top thereof the work support and finishing tool (hereinafter described) and at the bottom the main driving shaft 3 from which the several parts are actuated. The said shaft 3 is supported in bearings 4, adapted to be driven by a belt on the fast and loose pulleys 5 and 6. The other driving pulleys on the said shaft will be referred to in connection with their respective parts.

The work support or jack 7 for the boot 8 is of any well known construction and carried on the upper end of a vertical rod 9 mounted within bearings 10 on the frame 2. The said vertical rod 9 (hereinafter termed the jack rod) is adapted to be rotated by worm gearing comprising a worm wheel 11, mounted on the said jack rod and a worm 12 carried on a horizontal shaft 13. This shaft 13 is supported in suit-able bearings 14 in the frame 2 and is provided with pulleys 15, 16 and friction clutches 17 18. The pulleys 15, 16 are mounted so as to run loose on the shaft 13, and are driven in opposite directions to each other from pulleys 19, 20 respectively on the main shaft 3. The clutches 17, 18 are formed in one part and are mounted on a feather (not shown) in the shaft 13 so as to be capable of a sliding movement thereon to move into and out of contact with their respective pulleys.

When the pulley 15 and clutch 17 are in gear the shaft 13 and jack 7 are driven in one direction, and when the pulley 16 and clutch 18 are in gear the said shaft and jack are driven in the opposite direction. A shipper lever 21 is slidably supported in the frame 2 and a roller 22 thereon is located between the two pairs of pulleys and-clutches to simultaneously move the clutches into and out of contact. When the jack 7 has moved around in one direction to a point where the finishing tool reaches the end of the edge of the forepart of the sole 2'. e. the point where it adjoins the shank, an arrangement of cams 23 on the underside of a table 24 carried by the jack rod 9 acts on a roller 25 on the shipper lever 21 and causes the latter to slide and change the clutches and thus reverse the motion of the jack. The opposite action of the clutches will take place when the opposite side of the boot sole is moved around sufficiently far and this operation is automatically repeated until the sole edge is finished and the machine stopped. In order to rotate the pulleys 15, 16 in opposite directions they are driven by cross and open belts 26,

27 respectively.

The edge setting tool 28 is vibrated by a rapidly oscillating arm 29 actuated from a crank 30 on a shaft 31 in the well known manner. The said shaft 31 is supported in v bearings 32 in the head 33 of the machine and is flexibly driven by means of a pulley 34 and belt 35 from a pulley 36 on the main shaft 3.

The tool head 33 is mounted on a slide bed 37 so as to be able to move to and fro relatively to the jack as required for various sizes and lengths of boots.- The slide bed 37 is mounted on a bracket 38 attached to the top of the frame 2 in a convenient manner, the said slide bed being connected to the bracket by means of a joint pin 39 and vertical pin 40. The edge setting tool 28 is preferably carried by a holder located on the forward end of a rod 41 slidable in the head 33 and oscillating arm 29. Suflicient clearance space is provided in the head 33 to permit the rod 41 to oscillate with the arm 29. This rod 41 is constantly moved in a forward direction to maintain the tool in contact with the edge of the sole by means of pivoted bell crank levers 42 and counterweights 43, located on each side of the head 33 as shownin Fig. 1. In order to keep the tool 28 always square and parallel with the sole edge as the boot 8 is moved around on the ack as previously de scribed, a cam or templet 44, Figs. 2 and 3, is

,that as the jack 7 and table 45 rotate, the roller 46 will under the influence of the cam cause the slide bed and tool head to move horizontally on its oint pin 39 as shown in Fig. 3, and thus constantly turn the tool 28 to a square and parallel position with the varying contour of the sole edge of the boot 8. The flexible drive to the tool shaft 31 as previously described will permit of this horizontal movement of the head 33 and the supporting bracket 38 is, as shown in Figs. 2 and 3, extended sidewise radially with the joint pin 39 to support the slide bed in its various positions during the finishing of a I boot sole edge.

In combination with the slidable rod 41, bell crank levers 42, and counterweights 43 previously described for moving the tool 28 forward, it is necessary to provide means by which the said tool may be withdrawn and held from contact with the sole edge of the boot for the purpose of changing the said tool or the work in the jack. These means preferably consist of a hand lever 48 (Fig. 1) attached to a spindle 49 pivoted in the head 33, and arms 50 attached to the same spindle 49 and located on each side of the head. The arms 50, when the spindle 49 is turned by the hand lever 48, engage and move the bell crank lever 42 thus moving the rod 41 and tool 28 backward from the work.

In order to maintain the rod 41 in its backward or withdrawn posit-ion a spring controlled catch or drop lever 51 is pivoted to the side of the head 33 and this lever, when the before mentioned parts are moved to their extreme rearward position, engages a pin 52 on the side of the bell crank lever adjacent to it and maintains said lever 42 in this position until the catch 51 is lifted by a release handle 53 connected thereto and loosely pivoted on the spindle 49.

In order that the tool 28 may correctly follow the contour and inclination of the sole edge of the boot all around, the said tool is carried in such a manner on the end of the rod 41 that it may, in combination with the hereinbefore described movements of the jack 7 and tool head 33, automatically and freely yield and adapt itself to the correct angular inclination of the sole edge. For this purpose the tool 28 is supported by a holder comprising the several parts intermediate the rod 41 and tool 28 as shown in Figs. 4 and 5. It will be noted that the tool 28 has a hollow end 54 that fits upon the boss 55 of a slide plate 56. The said hollow end 54 of the tool is furnished with a bayonet or similar slot 57 therein arranged to engage a pin 58 projecting from the side of the boss 55. The arrangement of the slot 57 and pin 58 are such that when the tool is in position upon the boss 55 the pin will prevent the tool from leaving its place but at the same time will permit the said tool a certain amount of rotary freedom:

The slide plate 56 is movable vertically within the grooved face of a block 59 of approximately T section, and suitable tension springs 60 are attached at each side of the holder to the plate 56 and block 59 to normally hold the said plate in position. The stalk of the T section block 59 is located within the jawed or vertically grooved end 61 of the sliding rod 41 and pivot pins 62 in the said end are provided to form centers upon which the block 59 may turn. Compression springs 63 carried 011 pins 64 are located between the block 59 and the end of the rod 41 so that the said block is normally forced forward.

Then the tool 28 is in position on the boss 55 and is brought into contact with the sole edge of the boot as previously described, the said tool will be free to adapt its position to the sole edge (as the latter is carried past) either by rotating upon the boss moving up or down, vertically by means of the sliding plate 56 in the block 59, or in an angular or tilting direction by moving the block 59 on either of the pivot pins against the action of the springs 63, or by a combination of any or all of said movements. The tool may yield under pressure of the work relative to the rod 41 by compressing the springs 63 and may also yield with the rod 41 by lifting the weight 43 as above described.

A rotary stitch wheel such as 65 may or may not be employed with the tool 28 as desired.

It will be understood that the cams 23 are adjustable in their table 24, and that the cam or templet 44 may be interchangeable with others for various sizes and shapes of boot soles.

What we claim then is 1. An edge setting machine comprising the combination with a work support rotatable alternately in opposite directions, and a pivoted tool carrying member, of a roller on said member, and a cam rotatable in unison with the work support to engage said roller and cause the tool carrying member to move horizontally about its center coincidently with the rotation of the work support, substantially as and for the purpose described.
