STICK FOR SUPPORTING SHOE-LASTS.

Specification of' Letters Patent,

Patented Aug. 13, 1907.

Application filed June 23,1905. Serial No. 266,688.

To all whom it may concern:

Be it known that I, WILLIAM CnossLnY, a citizen of the United States, and a resident of West Haven, in the county of New Haven and State of Connecticut7 have invented certain new and useful Improvements in Sticks for Supporting Shoe-Lasts7 of which the following is a full, clear, and exact specification.

My invention relates to the appliances known as sticks used in connection with the manufacture of rubber boots and shoes for supporting theV articles, with the lasts or forms on which they are made, in the racks of the oven trucks or cars wherein they are assembled and transported from the work benches into the drying kilns. Said sticks commonly comprise simple bars of ii'on having their ends shaped and adapted to be received in the slots of the supporting racks on the frame work of the trucks and provided with a series of pairs of upwardly projecting pins at regular distances apart on which the lasts or forms are set in a compact row. i

The object of my invention is to provide a metallic stick of strong and light design that will not bend or sag with the weight of its load, which is a common objection to the aforesaid bars of iron, and which may be cheaply manufactured and will not readily become fractured or damaged with the rough usage the sticks are ordinarily subject to.

The invention consists in a novel form of combined tube and girder and in the combination, arrangement and construction of the parts and appendages of the stick as hereinafter more fully described and claimed.

In the accompanying drawings forming a part of this specification, Figure I is a perspective view of a section of my improved stick shown cut squarely across on the plane z z of Fig. 8. Fig. 2 is a cross section on the same plane as that of Fig. I but showing a modification in which a part only of the novel features illustrated in that figure are employed. Fig. 3 is a similar view to Fig. 2 of another modication. Fig. 4 is a plan view of one of the saddles by means of which the pins for the support of the lasts are mounted on the sticks. Fig. 5 is a cross section on the same plane as that of the preceding figures, of a modification of the girder tube. Fig. 6 is a Fig. 7 is a central longitudinal section of my improved girder tube provided with a flange for adapting it to b e used for structural purposes. Fig. S is a view of the end section of a stick showing the saddles in plan view. Fig. 9 is a cross section on the line :c x Fig. 8. Fig. I0 is a cross section on the line y y Fig. 8. Fig. II shows an end view of a stick and a side elevation of one of the supporting racks of the oven trucks or cars, with a form shown partly in cross section mounted on the saddle or bracket,

Referring to the drawings A designates my improved girder tube, which is comprised of a sheet of metal rolled into cylindrical or other suitable hollow form with its edges b1 b2 lapped and having the edge of its innermost lapped portion b1 bent inwardly as shown in Fig. l to form a nearly radial flange or girder B throughout its entire length. The construction is substantially the same when the tube is made in forms other than cylindrical, as for instance the tube AG of oval cross section shown in the modification in Fig. 5, o1' a rectangular tube having flat sides A5 as shown in Fig. 6, but the circular cross sectional outline can be more readily shaped than the other forms, as thebend or deflection of the sheet of metal from its original flat plane is distributed over its entire surface. K

For use as a stick for the support of forms for rubber articles the tube is ordinarily from four to six feet in length, and along the side on which the edges of the rolled sheet metal are lapped are arrangedtJ row or series of saddles H, fitted to the curve of the tube and mounted from six to ten inches apart when adapted for boot and shoe lasts, each fastened in place by a pair of rivets E extended diametrically across the tube from one side to the other through suitable perforations a3 in the lapped portions I)1 b2 thereof and the perforation a2 inthe opposite side al, the heads el of the rivets being on the side al opposite the saddle. The parts eL of the rivets, which pass through the saddles and lapped portions of the tube are reduced in diameter to provide shoulders e3 on the inner side of the inner lapped portions bl, and the projecting ends e4 are riveted over on the surface of the saddle, thus clamping the saddles and the lapped parts rigidly together as shown in Figs. l and 5. The saddles may be riveted upon ordinary tubes i in the same manner, as'shown in the modification in Fig. 2. In the modification in Fig. 3 the saddle H2 is shown with the rivets lo cast integral therewith, in which case the shoulder and the riveted part of the rivet are brought uponthe side of the tube opposite the saddles, as also are the lapped portions of the tube, b1 b2.

The saddles are each provided with a pair of upwardly projecting pins or studs h1 placed parallel in a plane substantially at a right angle with the axis of the tube, and adapted for engagement with corresponding sockets l2 in the forms or lasts I3 on which the rubber shoes li or other articles are molded. The pins and the saddles together form brackets for supporting said lasts or forms on the sticks, and are so termed in use.

In each end of the tube is fitted a plug L, having its projecting end of rectangular cross sectional outline to fit in suitable corresponding receiving recesses or spaces m which are provided in the racks m1 of the oven trucks or cars to support the sticks. The plugs are riveted in place by ordinary rivets m2 passed through the plug and the sides of the tube, and they are provided with slots m3 fo the reception of the ends of the girder or flange B. 'Ihe flattened ends of the plugs are commonly placed at such angle with the plane of the saddles that the latter will set nearly level when the sticks are placed v becomes expedient to do so, the requirement being tion, or from ten to eighteen inches in sticks oi ordinary moved from the sticks, the latter are returned to the in the racks oi the oven trucks, as shown in Fig. ll. Said racks are of various designs and constructions, adapted for being bolted to the uprights or posts of the oven truck in horizontal position. The section of the one here shown comprises a bar of angle iron having suitable bolt holes u, bored through its vertical side u1 or attachment to the uprights of the car, and a series of vertical metal tongues t, riveted to its horizontal side t1 to form the spaces m for the reception of the ends of the sticks, as sufficiently shown in said figure,

The angle of the receiving spaces m relative to a vertical plane is usually from forty to sixty degrees, and is determined and proportioned with reference to convenience in placing the sticks into and removing them from the racks. The saddles are set in planes other than horizontal when the shape of the iorms is such that it that the center oi gravity of the load of forms shall draw somewhat to one side oi the vertical plane of the stick in order that the latter may rest steadily in the racks free from vibration as the oven trucks or cars are wheeled on their tracks through the shop from the work benches to the kilns.

Between the brackets, at the distance from each end oi the stick most convenient to be grasped by the hands in carrying or holding the stick in the horizontal posilength, a pair' of grips n are riveted, comprising castings of curved cross sectional outline, riveted on opposite sides of the tube by rivets passed through the parts. The leverage of grasp provided by the oval section of the stick at those points or departure from the cylindrical form enables the tube to be conveniently held and handled, secure against turning by the weight of its load. In the modiiications shown in Figs. 5 and 6 this result is secured by the shape of the tube and the grips may be dispensed with.

In the manufacture of rubber shoes, the sticks are set up in a horizontal position infront oi the work benches with the saddles upward, and the lasts with the shoes thereon in inverted position are placed upon the pins as shown in Fig. ll in a compact row or series. The sticks When iilled are placed on the racks of suitable cars or trucks whereon the shoes are wheeled into the drying kilns and remain during the baking process. When the cars are run out from the kilns and the shoes rebenches to be reiilled for the next baking operation.

The sticks constructed as described do not sag With l their loads or become warped by the heat oi the kilns, and are convenient for handling and durable in use. The improved girder form of tube is less expensive than ordinary tubing and it is also adapted for s ructural uses. For such purposes it may be provided with a coupling flange G at the end, as shown in Fig 7 or other suitable part for fastening it in place in structures, said parts being slipped upon the end of the tube and riveted in place by the rivets E formed and arranged as described in connection with Fig. l.

I claim and desire to secure by Letters Patent:

1. A tube comprised of a sheet of metal rolled into tubular form with its edges lapped and having the edge of its inner lapped portion bent inwardly to form a nearly radial flange or girder, lengthwise of the tube, in combination with rivets passed from one side of the tube to the other having necks or reduced parts itted through the lapped portions of the tube and riveted over thereupon substantially as and for the purpose specified.

2. A stick for supporting shoe lasts or forms comprising a sheet of metal rolled into tubular form with its edges lapped and riveted together and having the edge of its inner lapped portion bent inwardly to form a nearly radial flange or girder lengthwise of the tube, in combination with a series of form brackets mounted upon and arranged along the tube, and comprising saddles secured on the tube by means of the holding rivets thereof, and pins projecting from the saddles substantially in the Amanner and for the purpose specified.
