CHARLES L. MILLER OF SOUTH NORWOOD, OHIO, ASSIGNOR '10 UNITED SHOE MACHINERY COMPANY, OF PATER-SON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

T 0 all whom it may concern:

Be it known that I, CHARLES L. MILLER, a citizen of the United States, residing at South Norwood, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Sole-Laying Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to .sole pressing machines, and more particularly to that class of sole pressing machines which comprise a shoe supporting jack and a sole pressing pad.

The invention is particularly adapted for use in connection with sole laying machines of the class disclosed in the patent to O. E. Holland, No. 362,447, dated May 3, 1887, in which the jack and pad are moved by the operator relatively to one another to position the shoe, and power operated means are provided for actuating the pad to press the sole of the shoe.

In the operation of sole laying machines of the types above referred to as heretofore constructed the operator lowers the shoe carrying jack by means of a foot treadle until the shoe engages the pad. After the jack is lowered the treadle is released and the jack automatically locked in its lowered posit-ion. Then the pad actuating mechanism is set into operation to press the sole, said mechanism moving the pad a certain predetermined distance. It has been found that when certain styles or shapes of shoes are thus positioned by being brought into contact with the pad, the pressure exerted by the pad in its upward movement is extreme, resulting in injured lasts and pads.

' Accordingly, a feature of the present invention in its broader aspects contemplates the provision of a shoe-supporting jack and a cooperating sole-pressing pad, adjustable means under the control of the operator whereby said jack and pad may be moved relatively to one another a predetermined distance to position the shoe in a predetermined manner, and power operated means for pressing the sole acting to impart a further predetermined relative movement to the jack and pad.

Specification of Letters Patent.

Serial No. 512,789.

A further feature of the invention contemplates the provision of a shoe-supporting jack and a cooperating sole-pressing pad, means actuated by the operator for lowering the jack, adjustable means for determining the movement of the jack according to the style or shape of shoe to be operated upon, and power operated means for actuating the sole pressing pad acting to impart a predetermined movement to the pad.

In the specific embodiment of the invention hereinafter set forth, the machine comprises a shoe supporting jack which is connected to a treadle by means of an adjustable rod, said treadle being depressed by the operator against a stop. The length of the treadle rod is adjusted to position the shoe according to the particular style or shape of shoe which is to be operated upon. 7

A machine embodying the present invention in its preferred form is illustrated in the accompanying drawing, which is a view in side elevation of the machine with a portion of the driving pulley broken away to show underlying parts.

As shown in the drawing, the machine comprises a shoe-supporting jack having a heel post 1 and a toe post 2 adjustably secured upon a cross-head 3 which is slidably mounted upon vertical guide rods 4. The

rods 4 project upwardly from side standards 5 and are provided with collars 6 between which and the cross-head 3 coiled springs 7 are interposed. These springs normally hold the cross-head elevated in the position shown in the drawing, and return it to this position when it is released after being clepressed. The cross-head 3 is connected by a rod to a foot treadle 8 by which it is depressed by the operator. Clutch collars 10 are mounted to slide upon the rods 4 and act to lock the cross-head 3 in its depressed position until released by the operator, as is fully described in the patent to Davenport, No. 781,636, dated February 7, 1905.

The sole-pressing pad is indicated at 12, and is mounted in a pad carrier 14 provided with collars having a sliding engagement through an eccentric strap and link 18 and a link 20, the link 20 being provided with a slot through which the shaft passes, and the arrangement of the eccentric and links being such that a complete rotation of the shaft 17 raises and lowers the carrier'li and the pad supported therein. The shaft 17 has secured thereto a gear 22 which meshes with a pinion 24 upon a driving shaft 25, said driving shaft having a driving pulley 26 at its rear end mounted to rotate loosely thereon. A friction clutch is provided for clutching the driving pulley to the shaft, the clutch being of well-known construction, and being actuated to clutch the pulley to the shaft-by a lever 28 which engages a grooved collar 29 mounted to rotate with and move longitudinally on the drivingshaft. The lever 28 is pivotally connected to a lever 30, which in turn is pivotally connected to a shipper-rod 31 slidably mounted in the side standards 5.

In the machine of the type disclosed in the patents above mentioned, the cross-head is connected to the treadle by a connecting rod of fixed length. In the Operation of these machines it is customary for the operator to lower the jack by means of the treadle until the shoe engages the pad. The jack is locked in this position and then the pad is pressed against the shoe by means of the power operated mechanism above set forth. By this mode of operation certain styles and shapes of shoes are subjected to an extreme pressure by the pad, which often re sults in injury to the lasts and pads.

In the specific embodiment of the present invention the crosshead 3 is connected to the treadle 8 by means of an adjustable connecting rod which comprises two sections 32 and 84:, one of which is secured to a block 35, and the other of which is adapted to slide through the block 35 and is held in ad justed position by a clamping screw 36. A stop 37 is provided for limiting the downward movement of the treadle. By means of the above construction the cross-head is moved downwardly by the operator to posi tion the shoe positively in a predetermined manner, the stroke of the treadle being adjusted in accordance with the style or shape of the shoe being operated upon, and the treadle being depressed by the operator until it engages the stop. Thus the amount of pressure exerted by the power operated pad upon the shoe can be adjusted in a predetermined and positive manner according to the particular shape of shoe which is being operated upon.
