LULMLAn J l; ATTORNEY Patented Feb. 25, 1936 UNITED STATES ATENT OFFIE 3 Claims.

This invention relates to work stands and particularly to such as are chiefly adapted for shoe making and repairing.

An object of the invention is to provide a stand, which may be secured upon any suitable foundation, and is held firmly at any height to which it is adjusted.

A further feature is to provide a stand having a: table which may be rotated relative to its supporting upright and held in any position thereon.

Another purpose is to produce a stand having means to operatively engage with a shoe makers last at the heel and also an adjustable support for the toe portion of the last.

These and other advantageous objects, such as independently adjustable, material containing devices, means to prevent articles from falling off the table, and means for holding the last in various positions, are accomplished by the novel and practical construction, arrangement and combination of parts hereinafter described and shown in the accompanying drawings, in which:

Figure l is a perspective view showing a complete embodiment of a stand as made in accordance with the invention.

Figure 2 is a similar view of the same, the last being omitted.

Figure 3 is a side elevational view of the complete apparatus, parts being in section to show the construction.

Figure 4 is a fragmentary sectional view taken on line 4-4 of Figure 2.

Figure 5 is a similar sectional view taken on line 5-5 of Figure 2.

Figures 6, 7 and 8 are perspective views showing attachments for the stand structure.

Figure 9 is a perspective view of an attachment to the stand table for finishing the shoes.

Referring in greater detail to the drawings, the numeral I0 designates a rigid pedestal having openings through which securing means may be passed to hold the apparatus firmly upon a flooring. This pedestal is preferably circular and has a raised central hub II, in which is firmly set a tubular upright I2.

A solid column I4 is slidably engaged within the upright l2 and provided midway its length with a pin engageable selectively in depressed notches |6I6--I6 from which are open passages leading to a longitudinal slot l? in the wall of the tube I2, this arrangement permitting raising or lowering the column l4 and affording a firm and secure holding means therefor.

Near the top of the upright I2 is a collar l8 provided with a set screw l9, opposite to which is an extending lug bored to receive a rod 2| having an outstanding horizontally disposed radial arm 22 upturned at its outer end to engage in a holder 23, provided with partitions to form compartments receptive of nails, slugs, pegs and 1 the like, so as to be readily accessible to the operator.

The upper end of the column 14 has a reduced portion 24 tight fitted into a central opening in a disc 25 provided with peripheral teeth 26 in the manner of a ratchet; this disc is disposed directly below the under surface of the table 28 of the stand and through which the continuation 24 of the column element l4 passes.

Also fixed to the underside of the table is a radial bracket 29 bored to receive a plunger 30, engageable with the teeth 25 of the disc, and forced there against by a coiled compression spring 3|, which may be tensioned by a screw 32, easily accessible by the operator.

Obviously, if the spring is fully compressed the plunger, acting as a detent, will restrain the rotary movementof the table, but if relaxed permit the table to be turned by applying force.

A U shaped clamp 34 may be bolted to the top of the table and provided at its inner, reentrantly, turned end with a set screw 35 by which the table may be securely and positively clamped to the disc 25 so that relative rotary movement is prevented.

A block 36 is mounted on a pivot 31, extending upward from the upper surface of the table 28, this block being normally rocked into a forward position by a coiled compression spring 38.

A pin 39, fixed in the upper portion of the block, is suited to enter the usual opening formed in a last, as clearly indicated in Figures 1, 2 and 3.

This block, in addition to being pivotally mounted, may be withdrawn and another substituted by releasing a screw 40, set in the upper end of the column M, the end of the screw impinging upon a bar 41, the upper extending end of which is formed into a head to receive the pivot 37, and as shown in Figure 3, the disc 25 and column l4 are further held by one or more pins 43.

The table 28 has a radial slot 45 through which slidably passes the squared lower end of a support 46, adapted to receive the forward portion of a last, or a shoe on the last. The squared portion of this support terminates in a screw thread 41 to receive a clamp nut 48, thereby affording means for adjusting the distance between the support 46 and block 36 at one side of the table 28, which is provided with a raised rim 49.

A suitable opening in the table is receptive of the squared shank of a post 5|, which may be clamped by a nut 52, this post having a reduced upper end adapted to enter the opening in a last so that the last may freely pivot thereon.

A right angled block 55 is provided with a horizontal pin 56 to receive the last, permitting it to swing in another plane; the block 55 is provided with a stem to pass through another opening in the table 28 and is secured by a wing nut 54.

A horn 51, having a reduced flattened end is rigidly fixed in one of the corners of the table 28, remote from the column.

For certain operations in shoe repairing (see Fig. 6) it is found convenient to remove the block 36 by raising the bar ll and substituting a bar 60 on which is mounted a support 6| provided with a pin 6| at its upper end to engage in a ,last, this device being used exclusively in attaching heels to all kinds of shoes.

In Figure 7 is an attachment used mainly in repairing shoes, and consisting of a bar 62, which may be substituted for the bar 4 I.

Carried by the bar 62 is a head 63 having a central square opening 64 to act as a socket receptive of the shanks of metal lasts 65, as illustrated by broken lines in the figure, it being understood that metal lasts of dilferent shapes and sizes may be used in the head.

The shoe finishing apparatus, shown in Figure 9, consists of a pair of clamp jawes 101|, the latter lower jaw being provided with a set screw 12 to clamp the device rigidly on the table 28 and may be substituted for the clamp 34, a suitable filler being interposed below the upper jaw.

A stem 13, extends upwardly and outwardly, the same being surmounted by an inclined plate 74, presenting a firm level surface on which the wrinkles of a shoe may be smoothed, as by hammering a shoe disposed on the plate.

It is to be noted that the table may be adjusted in height to suit the convenience of a workman, thus avoiding bending, when in either a sitting or standing position, and the use of the table relieves the usual practice of pressing the shoe against the lower chest as is the common practice.

Although the improvements have been described with considerable detail and with respect to certain particular forms of the invention, it is not desired to be limited to such details since many changes and modifications may well be made without departing from the spirit and scope of the invention in its broadest aspect.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent, is:

1. A shoemakers stand comprising a table, an adjustable column on which said table is rotatably mounted, stepped means associated with said column to positively support said table at predeterminable heights, a toothed disc fixed on said column below the table, a spring actuated detent slidably mounted below said table to engage the teeth of said disc selectively, and means on said table for supporting a shoe last.

2. A shoemakers stand comprising an upright hollow column having an elongated slot and a plurality of notches leading laterally therefrom, a bar slidable in said column, said bar having a pin movable in the slot and selectively engageable in the mentioned notches whereby said bar is rigidly supported at predetermined heights,

at table rotatably mounted on said bar, means to retain said table in adjustment, means to clamp said table, and means carried by said table to adjustably engage a shoe last.

3. A shoemakers stand comprising a table having a circular portion and an apron portion level therewith, a raised border on the edge of said table and apron, a rocking block having means to engage the heel portion of a shoe last, said block being pivoted at the axis of said circular portion, and a shoe last toe support adjustable toward and from the axis of said block.
