MACHINE FOR OPERATING UPONQBOOT AND SHOE SOLES.

Application filed March 4, 1912. Serial No. 681,335.

To all whom it may concern) Be it known that I, ARTHU BATES, a subject of the King of Great Britain, residing at Leicester, in the county of Leicester, England, have invented certain new and useful Improvements in Machines for Operating Upon Boot and Shoe Soles; 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 machines for operating upon boots and shoes, and more particularly to machines for operating upon the soles of boots and shoes which comprise a rotary tool and mechanism for actuating the tool.

The object of the present invention is to provide an improved and eliicient machine of the character described for performing various operations upon the shoe sole which operates over all portions of the sole without the necessity of altering the lateral inclination of the shoe as presented to the machine.

With this object in view, a feature of the invention consists in the provision of a ro-o tary tool, a supporting shaft for the tool, and means for tipping the tool alternately in opposite directions to enable the tool to cover all portions of the sole as the shoe is passed across the tool.

Still further features of the invention consist in certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description.

In the accompanying drawings illustrating the preferred form of the invention, Figure 1 represents a plan view, partly in section, of a machine embodying the several features of the invention; Fig. 2 is a view similar to Fig. 1' illustrating a modified construction; and Fig. 3 is a section upon the line 33 of Fig. 2' looking in the direction of the arrows. v

The machine shown in the illustrated em bodiment of the invention is provided with a roll for operating upon the soles of boots and shoes and is employed principally for burnishing the surface of thesoles. The

roll is tipped laterally and caused to as sume different angles of inclination relatlve to the shaft by suitable means which, 'in the simplest and most ellicient form of the invention yet devised, comprlses a sleeve PIOVlClGCl withan oblique bore to receive the shaft and interposed between the roll and shaft. The sleeve or bushing supports the roll in an oblique.

position relativeto' the shaft, and when the sleeve and roll-are rotated relatively to one another a wabbling 'ortipping movement in opposite directions is imparted to the roll.

with the median line of the roll, thus im ,partlng equal tipping movements in opposite directions to the roll.

The roll 1s indicated'at 1, and is provided -Wltl1 a concave periphery in order to enable it to conform more closely to the surface of the sole 1n cross section.

The roll is supported upon a drive shaft 2 journaled at its 1 opposite ends in bearings 3 and'et'and actuated by a drive pulley6 keyed thereto. In order to lock-the roll against rotation relatively to the shaft, and to allow a free tipping of the-roll in any direction, a uni-' versal joint connection is provided between the roll andshaft. To this end a collar 10 .projecting lugs 18 located upon its opposite face and disposed at right angles to the lugs 11. The lugs 13 are received in cooperating recesses formed on one end of the roll 1, thus locking the roll to the driving shaft 2 and at the same time allowing the A second collar 12 isrollto. tip freely in any direction. The tipwping or ,wabbling movements are imparted to the roll by a sleeve l5interposed between the roll and shaft and connected to a drive pulley 16 through a; sleeve 17. --15 is cylindrical in form and is provided.

The sleeve with an oblique bore to receive the shaft 2. The roll is secured against longitudinal movement relative to the sleeve 15 by anannular shouldered ring 20 fastened to the roll by a plurality of bolts 22 and cooperating with a flange 23formed upon the sleeve. The roll is driven at a higher speed than the eccentric sleeve 15, thus causmg the movement of the roll through varying angles of without departing from the spirit and scope :of the invention.

is desirable that it be heated artificially, and

When the roll is used for burnishing it this is accomplished simply and efliciently by the employment of friction material conthe holder 31 by a ball and socket joint indicated at 33. The support 32 is normally pressed out by a coiled spring 34 received in the recess and interposed between the support and a threaded cap nut 35 closing the end of the recess.

In the modified form of construction illustrated in Figs. 2 and 3 the roll is indicated at 36 and is supported upon a drive shaft 37 journaled at its opposite ends in the machine frame. The roll is provided upon its interior with a spider 40 forming a hub for the roll and connected to the shaft by means of a key 41 engaging with a cooperating key-way formed in the spider. The key 41 is swiveled in a transverse slot formed in the shaft 37, and is provided with a T-shaped head 42 engaging with the spider. It will be noted from an inspection of Figs. 2 and 3 that there is sufficient distance between the sides and top of the key and key-way to allow all necessary movement of the roll relative to the shaft without cramping the key in its bearings. Tipping movements are imparted to the roll by a sleeve 44 bored obliquely and received in one end of the roll. The roll is secured against longitudinal movement relative to the sleeve by an annular ring 45 secured to the spider 40 and cooperating with a flange 46 formed upon the sleeve. Artificialheat is applied to the roll by a gas burner indicated at 50, which projects within the roll and is secured in a bracket 51.

The operation of the machine may be briefly stated as follows: The operator presents the shoe to the rapidly rotating roll, and then manipulates it to'cause the shoe sole to traverse longitudinally of the face of the roll. As the shoe is removed across the roll, the roll rubs and polishes each successive portion of the sole, and the tipping movements imparted to it alternately in opposite directions enable the roll to accommodateitself to the varying curvature of the shoe sole in cross section without making it necessary for the operator to alter the lateral inclination of the shoe.

While it is preferred to employ the spe cific construction and arrangement of parts shown and described, it will be understood that this construction and arrangement is not essential except so far as specified in the claims, and may be changed or modified without departing from the broader features of the invention.
