WILLIAM B. KEIGHLEY, OF VINELAND, NEW JERSEY.

SOLE-MOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 627,122, dated June 20, 1899.

Application filed May 24,1898. Serial No. 681,593. (No model.) I I To all whom it may concern:

Be it known that 1, WILLIAM B. KEIGHLEY, a citizen of the United States,residin g at Vineland, in the county of Cumberland, State of New Jersey, have invented Ia new and useful Improvement in Sole-Molding Machines, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to certain improvements in gripper attachments for sole-molding machines, whereby the sole is held against displacement from the molds during the operation of molding, the object being to provide in a simple and inexpensive manner a novel and effective device of this character which is readily applicable to most ofth'e solemolding machines at present in use and which is so arranged that the gripper devices will be automatically operated to grip the sole and to release the same after the sole has been properly molded. It also provides simple and convenient gaging devices whereby soles of varying sizes may be molded from one set of molds and the same uniformity maintained throughout after said gaging devices have been properly adjusted to mold any particular size.

It consists, substantially, of a mold, a gaging device to adjust the same for varying sizes of soles, a gripper attachment adjacent thereto, and means for automatically operating said gripper attachment to grip the sole and hold the same against displacement.

It further consists of the novel details of construction, all as will be hereinafter fully described, and particularly pointedout in the claims.

Figure 1 represents a front elevation of a sole-molding machine having my invention applied thereto. Fig. 2 represents ,adetail plan view of a slide to be described, showing the. lower mold in place thereon and my invention applied thereto. Fig. 3 represents a vertical section taken on the line a: at of Fig. 1, showing'the molds thereon in the act of pressing the sole. Fig. 4: represents a perspeotive view of the lower mold with my improved gripper attachment and gage applied thereto.v Fig. 5 representsa similar view of the upper mold. Fig. 6 represents a vertical longitudinal section of the heel portion of the machine only, (of which there'are two,) showing only such parts as will enable others to fully comprehend the same.

1 designates the frame whichsnpports the main driving-shaft 2, a counter-shaft 3, a crank-shafta, and a rock-shaft 5, the latter being provided with a loosely-mounted bellcrank lever 6,adapted to rock thereon through the action of the rod 7, which connects with i one end thereof and with a crank 8 0n the crank-shaft 4, by which means it receives its motion. The opposite endof the bell-crank lever 6 is connected by means of a couplinglinlr 9 to a vertically-disposed sliding frame 10, having upon its upper extremity a horizontal guideway 11, adapted to receive therein and guide a sliding carriage 12, on which latter the lower mold 13 is removably held. The rear end of the sliding. carriage 12 is provided with a perforated block 14, to which is pivotally secured one end of an adjustable connecting-rod 15, the opposite end of which is secured to an arm or lever 16, loosely mounted upon a shaft 17, journaled in the frame 1.

18 designates a spring connection between the bell-crank lever 6 and the lower end of the arm or lever 16, the object of which is to give aneasier movement to the sliding carriage and to compensate for any excess of motion of the bell-crank lever, it being evident that as the crank rotatesthe bell-crank lever will, through the mechanism just described, lower' the frame 10 and gradually move the sliding carriage 12 and connected mold l3 outwardly to receive thereon the soleblank to be molded.

Motion is imparted to the crank-shaft 4 through the media of a gear-wheel 19, secured to one end thereof, and a pinion 20, secured to the counter-shaft and intermeshing therewith, the latter receiving its motion from the gear-wheel 21, also secured to the countershaft, the same in turn being driven by a pinion 22, carried by the driving-shaft. Thus as the latter is rotated to put the operative parts into motion the sliding carriage is alternately raised and lowered and moved outwardly and inwardly at the proper intervals.

23 designates dowels projecting from the sliding carriage and adapted to enter sockets 24 in the base of the lower mold 13 in order that their relative position may be firmly maintained and that they may be easily removed when necessary.

The heel portion of the mold 13 is provided with a longitudinal slot 25, adapted to receive therein a gaging device 26, composed of a block 27, which projects above the surface of the mold and acts as an abutment againstwhich the heel of the sole contacts, the said block having a stem or rod 28, projecting therefrom, adapted to enter a suitable socket 29, wherein it is adjustably secured by means of the set-screw 30. The surface of the mold adjacent the walls of the slot is graduated on both sides and in such manner that any predetermined size of sole within the capacity of the mold may be operated upon by adjusting the said gage-block into alinement or register with the proper gradation.

31 designates a bar a-djustably supported in a socket 32, formed in the heel portion of the lower mold, and projecting sufficiently beyond the end thereof receives upon it an adjustable block 33, the said block being adapted to support a rock-shaft 34, to one end of which a gripper 35 is secured, the latter being slotted at 36 to admit a screw 37, whereby the said gripper may be adjusted to grip the sole at any desired or convenient spot. To the opposite end of the rock-shaft 34 is secured an arm 38, which extends rearward and downwardly, its extremity resting upon a cam-bar-39, two of which are secured to the frame 10, one at each side of and adjacent the mold 13, as clearly shown in Figs. 1 and 2. In actual practice one of these cam-bars is preferably omitted, but under certain conditions two may be employed, in which event of course another arm 38 will be provided at the opposite end of the rock-shaft, as shown in dotted lines in Fig. 2. A setscrew 33 serves to hold the block 33 in place on the bar 31 and permits of the adjustment of the gripping devices when desired.

40 designates a set-screw which engages a threaded opening in the mold and impinges the bar 31 and so secures it in place within the socket 32 and admits of the adjustment of the gripper devices, as will be evident.

It will be observed by reference to Figs. 2

and 3 that the cam-bars39 are bent upwardly intermediate of their ends, as indicated at 41, from which point they extend rearwardly in a horizontal plane, it being obvious, therefore, that as the sliding carriage 12 and its mold 13 are moved rearwardly, as described, the arm or arms 38 will ride up the bent portions of the bars 39 and rock the shaft 34, thus actuating the gripper to grip the sole,

which grip is retained until the sole has been properly molded, after which the forward movement of the sliding carriage will cause the arm or arms 38 to ride down saidinclines, and by their own weight the gripper will be moved to release its contact with the sole.

The upper mold 41, which is held in the head-block 42 of the frame 1, is provided in the heel portion thereof with a longitudinal slot 43, which when the said mold is in the proper relative position with the lower mold is in vertical alinement with the gripper 35, which latter normally projects above the level of the mold and enters said slot 43 when the molds approach each other, thus allowing the abutting surfaces thereof to close in upon the sole and mold it, as will be readily understood.

In Fig. 7 I have shown a somewhat different form of mold, the same being especially designed for use in molding spring or wedge soles, it being observed in this construction that a perceptible rise occurs at that portion of the mold between the heel and too, as indicated at 44, which formation is necessary in order that the additional stock and consequent increased thickness in the heel portion of the sole may be compensated for. The

gaging device hereinbefore described is also a set-screw 49, which engages a threaded opening in the front or toe portion of the mold, and by means of which screw the frame 45 may be adjusted to and fro to mold soles of varying sizes. In adjusting this form of gage the frame 45 is moved to bring the bar 48 in such position that the heel of the wedgesole will fit snugly between it and the rise or shoulder 44, after which the molding process can begin, it being understood that as the sizes of the soles increase the stock forming the heel becomes longer, and vice versa. Thus the graduations hereinbefore described are not necessary, as the length of stock in the heel serves for all practical purposes in gaging the different sizes.

The gripping device described will be used in connection with this mold, and the slot or opening in the upper mold will of course be unnecessary.

From the foregoing it will be seen that my invention provides in an efiective and economical manner a gripper attachment which is positive in its operation and which will securely hold the solo in place upon the mold during the operation of molding, thus insuring against all possible chances of displacement thereof and a consequent destruction of the sole. At the same time a succession of soles maybe molded in a-uniform and perfect manner, an accomplishment hitherto found impossible in heel-molding machines.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
