UNITED STATES PATENT oFFIoE.

ORRELL ASHTON, OF LAWRENCE, MASSACHUSETTS, ASSIGNOR 'IO UNITED SH'OE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all whom it may concern Be it known that I, OBRELL AsH'roN, a

citizen of the United States, residing at the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufactureof boots and shoes and particularly to shoe beating m achines.

An object of the invention 1s to provide a machine of simple construction comprising one or more tools adaptedto be rapidly vibrated or reciprocated for beating the bottom and preferably also the side of a shoe,

which mayv have been previously lasted, to shape the shoe on its side and bottom faces adjacent to its edge, together with an meX- pensive means for actuating the tools.

A novel characteristic of this machine is found in the provision of power driven means for lifting or retracting the beating. means and thereby putting under tension or' increasing the tension of a yielding elementthrough which the beating means is reversely actuated for doing its work.

A further characteristic of the .invention is found in novel means for avoiding the transmission of vibration from the beating tools and their actuating mechanism to the treadle by which the movement of said tools is controlled.

These and other features of the invention, including combinations of parts and certain more important details of construction, willappear in connection with the following description of a preferred embodiment of the machine and -will then be definitely pointed out in the claims at the end of the description.

The figure is a side elevation of the machine in which portions are broken away for disclosing details of construction.

The frame 2 of the machine has a pivot shaft 4 von which is mounted a lever 5, the lower arm or tail of which is formed eccentrical to a rotary driver 8, shown as provided with two oppositely disposed rollers 10 ad apted as the driver turns to contact with the tail of the lever near the fulcrum shaft 1 Specification of Letters Patent.

'12 and an adjustable collar 18 on the upper end of the rod. The spring 16 when com pressed by the treadle holds the tail of the lever 5 against the rotary driver. When the spring is not so compressed the lever is held 1 with its tail away from the driver by a light spring 20 so that the lever remains at rest at all times except when the treadle is held down while-the driver runs continuously.

The lever 5 pivotally supports at 24 an angle lever 25, the depending arm of which is yieldingly held between spring-pressed plungers 26 in the lever 5. The lower face of the front portion of the horizontal arm of lever 25 is suitably shaped to pound the bottom of a shoe and this lever constitutes the bottom beating tool of the machine. The lever is provided with bearings 28, 29 for a sliding rod 30 having on its front end a tool 32 shaped and arranged to beat the side of the shoe for blocking or shaping the shoe in cooperation with the bottom beating tool. The blocking tool and its supporting rod-3O slide lengthwise by reason of their inertia when the lever 25 is vibrated to beat the bottom of the shoe. In this sliding movement the blocking tool retreats as the pounding tool rises and then suddenly changes its direction as the driver slides ofi" the tail of lever 5. The blocking tool then advances as the pounding tool comes down and as the movement of the latter is abruptly checked by engagement with the work. A spring 34: is held under tension gagement of the roller 10 with the tail near the fulcrum of the lever. As a roller 10 passes the tail of the lever the spring 16, which has been put under compression by the action of the driver, is permitted to expand and actuates the beating tools downwardly to do their work. The force with which the beating tools will thus be actuated depends upon the extent to which the treadle is depressed and the spring 16 thereby compressed so that the operator can, by depressing the treadle more or less, control the action of the beating tools upon the work. The shoe is supported on the jack, which may be of known construction, and is arranged to permit the shoe to be turned for presenting different portions thereof to the action of the beating tools.

The treadle is connected to the rod 14 by a link 40 and a U-shaped casting 42. The treadle link is pivoted to the casting at 44 and to the same pivot pin 44 is connected a swinging arm 45 connected to the'machine frame by a pivot rod 46 against which the rear arm of the U-shaped casting also has hearing. The arrangement is such that the arm 45 holds the casting 42 against the rod 46 when the treadle is released. When the treadle is fully depressed the parts are swung into the dotted line position wherein the arm 45 and the rod 40 occupy substantially the relation of toggle members which are straightened or on dead center and the casting 42 rests upon the rod 46. This rod 46 thus steadies the treadle and the parts connected with it and largely relieves them of the vibration which could otherwise be set up in them by the vibratory movement of the lever 5 and the tools.

Having explained the nature of this invention and described a'preferred construc tion embodying the same, I claim as new and desire to secure by Letters Patent of the United States:
