F BOOT OR SHOE CLAMPING DEVICE.

SPEGTFIGATION forming part of Letters Patent No. 627,576, dated June 2'7, 1899.

Application filed August 1, 1898- $erial No. 687,473. (No model.)

vented a new and useful Improvement in Boot-Clamps for Use in Blacking Boots or Shoes; 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 object of my invention is to provide means for holding the boot or shoe firmly in position during the operation of polishing it.

It consists of a plate or rest which is made to conform in shape with the bottom of a boot or shoe and having a central longitudinal slot in its sole portion, said plate being provided with two sets of link-levers movable on its top surface, each pair of links being connected together at their outer ends by a Vertical stud to engage with the edge of the sole of the shoe and their inner ends being connected together by a screw-threaded bolt, which enters the slot of the plate and engages with a thumb-nut, which serves to operate in securing the parts in a fixed position.

In the accompanying drawings,Figure 1 represents a side elevation of my improved device as attached to a standard with the shoe in position thereon. Fig. 2 is a top plan view of the plate, showing the position of the linklevers as when the sole of the shoe is clamped to the device. Fig. 3 is a side elevation of the same. Fig. 4 is an enlarged sectional View taken in line X X of Fig. 2, showing the heel-spur as secured to the wall of the plate.

Fig. 5 is a sectional view taken in line Y Y of Fig. 2, showing the manner of attaching the clamping-stud to the links, said stud bearing against the edge of the sole of the shoe, which is illustrated 'in partial section. Fig. 6 is a sectional View taken in line Z Z of Fig. 2, showing the screw-threaded bolt and its thumb-nut in elevation.

Letters of reference correspond to similar parts in the drawings. y

A designates the plate or-rest, made of thin sheet metal and conforming in shape to the bottom of a boot or shoe, as seen in Fig. 2.

B is a slot extending longitudinally through the sole portion of the plate. Links 0 0, com- .Wardly prising two sets, each of equal length, are placed over this slotted portion of the plate in a diamond-shape form and each pair of links having their outer ends connected together by the vertical studs d d (see Fig; 5) and the inner ends of each pair of links being connected, together by the screw-threaded bolts 6 8', (see Fig. 6,) said bolts projecting downwardly through the slot B and engaging the thumb-nutsff.

Grepresents the spur-stud, which is riveted to the vertical heel-wall of the plate, said stud being made sufficiently sharp to be readily forced into the front edge of the heel of a boot or shoe.

The plate A is rigidly secured to a suitabl standard or pedestal P by screws 1', said standard having an expanded base 3, fastened by screws t to a raised platform.

The operation of my device is as follows: The boot or shoe is placed in position on the plate or rest, as seen in Fig. 1. The operator then draws the screw-threaded bolt e forward, which movement causes the links 0 C to close inwardly and bringing the vertical side studs 01 d to bear firmly against the edge of the sole of the shoe. The thumb-nut f is then screwed up tightly, after which the shoe is ready to be polished. The rear screwthreaded bolt 6 does not have to be adjusted except in such cases that require a greater scope for clamping the sole to the shoe. When the boot or shoe is polished, the thumb-nut e is slightly unscrewed and pressed back rear- .which movement swings the linkd outward from the edge of the sole studs Fig. 2.

By my construction I form a very simple,

compact, and durable clamping device for the use of boot-blacks, at the same time exposing all parts of the shoe, thus enabling the operator to have the free use of both hands for the action of polishing. p

What I claim, and desire to secure by Letters Patent, is

1. The combination of the plate or rest conforming inshape to the bottom of a boot or shoe, said plate having a slot ext-ending longitudinally through the center of the sole portion, the two pair of link-levers movable ina diamond-shape form upon the top'surface of the plate, each pair of links having their outer ends connected together by the short vertical studs which engage against the edge of the sole of the shoe, and their inner ends connected together by the screw-threaded bolts which project downwardly through the slot of the plate and engaging the operating thumbnuts beneath, with the spur projection riveted to the vertical wall of the plate to catch in the front edge of the heel, substantially as shown and for the purpose specified.

2. The combination of a clamping device for boot-polishing, consisting of the plate A conforming in shape to the bottom of a boot or shoe and provided with a slot B extending longitudinally through the center of the sole portion, the links C C movable upon the top surface of the plate, the vertical studs (1 d connecting the outer ends of the links, the screw-threaded bolts '6 8 connecting the inner ends of the links and projecting down- Wardly through the slot B of the plate, the

adjustable thumb-nuts ff engaging on said NATHAN B. DENISON.
