CHARLES E. HOLLAND, OF BOSTON, MASSACHUSETTS, ASSIGNOR 'TO THE BOOT AND SHOE SOLE LAYING COMPANY, OF SAME PLACE.

BEATlNG-OUT MACHINE.

SPECIFICATION forming part of Letters Patent No. 361,628, dated April 19, 1887.

Application tiled February 8, 1887. Serial Noi 226,916. (No model.)

To @ZZ whom it may concern:

Be it known that I, CHARLES E. HOLLAND, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvementsin Beating-Out Machines, of which the following is a specification.

This invention relates to machines for beating out7 or leveling boot and shoe soles so that they will be given a symmetrical appearance and have the proper shape imparted thereto. In machines of this class itis usual to provide two lasts having supporting-arms attached to a cross-head adjustable on standards rigidly secured to a frame or base, a shapingpad adapted to be moved up against thelasted shoe, and means for applying pressure thereto, the arrangement being such that while one sole 1s being acted on by the shaping-pad the other may be in a position to be applied or removed by the attendant.

My invention has for its object to provide certain improvements relating to the construction of the cross-head and adjustable devices therefor, the last-supports,and devices for operating the same, all of which I will now proceed to describe. I.

Of the accompanying drawings, forming a part of this specification, Figure l represents a front elevation of a beating-out machine embodying my improvements. Fig. 2 is a sectional view of a portion of the machine on the line x x, Fig. 1. Fig. 3 is a section on theline y y, Fig. 1.

The same letters of reference indicate the same parts in all the gures.

In the drawings, a represents the frame or base of the machine, to which are rigidly secured upright standards Z b, adapted to serve as guides for the sliding frame o, on which is located the shaping-pad d, adapted to be moved up against the lasted boot or shoe by an arm, e. Said shaping-pad is preferably made of .metal, adapted to tit the bottom of a last, and

is supported by a frame, f2, provided with trunnions t t2, j ournaled in sockets t3 t3 in the sliding frame c'. The pad d is supported upon a number of stout spiral springs, 3,which support the pad with a yieldingpressure, the pad being adapted to be depressed as the frame c 5o is raised. l

Arm e is pivoted to ears on the lower end of the sliding frame and surrounds an eccentric, f, on a shaft, g, journaled in bearings in the base a, and driven by any suitable power applied to shaft a3 (shown as broken oft', Fig. l) and gear a, attached to shaft a3 and meshing with a gear, a5, on shaft a,Which shaft has a gear meshing with gear al on shaft g. The

crosshead h is adjustable longitudinally on 6o the upright standards by means of nuts t' t', having grooves t2, into which project lugs jj', bolted to the cross-head. This engagement enables the nuts to raise or lower the crosshead when they are turned on the threaded upper ends of the standards. Said cross-head is constructed so as to permit of the rotation of thelast-supporting devices thereon,and has a central cylindrical portion, k, on which the central portion of said supporting devices may 7o operator may work on the shoe with either the toe or heel portion of the same toward or from him. It is usual in machines of this class to construct the last supports in such manner as that they are only adapted to be rotated on the cross-head and always stand 8o in the same position to the operator. In some machines the heel portion of the shoe will be toward the operator, and in others the toeportion, so that when one becomes accustomed to working on the shoe in one position it becomes inconvenient to work in any other,and when an operator changes from one machine to another, where these conditions exist, it causes inconvenience, as will be readilyseen.

To obviate the objections just enumerated, 9o

I have constructed my machine so that the lasted shoe can be operated upon from either .the heel or toe of the same, as may be desired.

To this end I divide the last-supporting devices in sections so arranged as to form swivels on which the lasts can be rotated, as/Iwill now proceed to explain.

The last b is constructed with a dovetail por is adapted to coincide with hole q when the tion, m, fitted to slide into a dovetail groove n, in the last-supporting arm o. A pin, p, enters a socket formed in the last, for the purpose of holding the last in position on its supportingar1n. Said pin is constructed with a shoulder on its upper end, with which engages a spring, r. The top of pin p is beveled, so that the lower side thereof shall come below the surface of groove n, and will be depressed by the dovetail portion of the last whenever the same is applied to the supporting-arm, and

last has been placed in its normal position on its support, and thus hold the last firmly in place, and when necessary to remove the last, pln p can be depressed by pulling it down a sufficient distance to allow the last to be removed, as will be readily understoodby ref erence to Fig. 2.

rlhe upper portion of the last-support con sists of an arm, o, having a circular base, s,

provided with lugs t t, set opposite each other on the periphery of said circular base. Pins 'u u', screw-threaded in said lugs, are adapted to enter the grooves o o' of the lower portion, w, of said support, Figs. l and 3. The V- shaped groove i; cut in the periphery of the portion w serves as a guide for pin u when the upper portion of the last-support is to be rotated, said pin serving to hold the upper-portlon in place and permit of its free rotation by the operator.

It will be seen by reference to Fig 3 'that pin u extends farther into the part w than pin u. This arrangement is for the purpose of providing a stop to govern the rotation of the part s and last-supporting arms o, as said pin will allow said portion s to turn only one-half of a revolution, which movement will bring the toe or'heel portion of the shoe toward the operator.

- The lastsupporting arms o and their swiveled base are secured to a rotary head journaled on a support or bearing, k, ofthe crosshead, and adapted to rotate thereon. Said rotary head is constructed in two parts, a b', provided with ears d c' to receive bolts, by which means said parts are secured i-n position on the crosshead and are adapted to be readily detached from the same. Each part a. b of the rotary head is provided with a tongue, a2,

adapted to engage wit-h a groove in the circular base w, and thereby secure the same to the rotary head. Said tongues a2 are secured to the parts a' b of the rotary head by screws b2, or may be made integral therewith. This construction permits of the ready removal of the several parts, for convenience in repairing or other purposes. The head is rotated by hand to bring the desired part of thelast to the front.

In case it is desirable to stop the rotation of the driving-shaft automatically when the shaping-pad is at the extreme of its `movement,the means employed Vfor this purpose are of the same nature as those shown and described in an application led by me for a patent for improvements in sole-laying machines, filed on even date with lthis application, the construction and operation of said means being identically the same.

vI claiml. In abeating-out or leveling machine, the combination,with the sole-pressing pad or die and mechanism for operating the same,of the rotary headv having the independently-rotatable last-supportin g arms, whereby the last may be turned to present either end at the front of the machine. y

2. The rotary head journaled on a supporting cross-head or holder, combined with the lastsupporting arms connected to said head by means substantially asdescribed, whereby sai d armsv are adapted to be turned independently to present either end of thelast at the front of the machine, as set forth.

3. The combination of a support or bearing, as 7c, the rotary head journaled on said bearing and having the circular plates w,peripherall v grooved, and the last-supporting arms adapted to rotate on said plates and having the circular bases s,provided with lugs tt,and pins u u', projecting into the grooves of the plates w, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of 95 two subscribing witnesses, this 26th day of January, 1887.

CHAS. E. HOLLAND.
