Claims.
This invention relates to jacks for masons, ainters, carpenters, and other workmen and for an object to provide a jack which may vorn on the feet in pairs when working on low gs and walls at places inaccessible but not 1Gb. enough to warrant building a staging. er object is to provide a jack of this type strong and durable, will be and may be applied and retime and with minimum eft ithi In the accompanying drawing forming part of this specification,
n Figure l is a perspective view showing the jack 1n use,
2 is a plan View of the jack,
Figure 3 is a side elevation of the jack,
Figure l is a cross section taken on the line 4-4 of Figure 2, and
Figure 5 is a detail cross section taken on the line 5--5 showing the adjusting means.
Referring now to the drawing in which like characters oi reference designate similar parts in the various views, 10 designates a substantially oval base plate at the bottom of which is attached a pair of longitudinal runners 11 which preferably are formed of strap metal bent to provide treads l2, the strap metal being bent up at the ends and inclined inwardly to provide iront and rear risers 13 and 14. The risers of both runners are riveted to the ends of the base plate, as shown at 15.
is lifted and lowered on the jack while stepping.
A sole plate 20, o substantially the same shape as the sole of a shoe, supported upon the base plate preferably by means of three pins 21, a pair of the being arranged at the toe por- 6o tion of the plate 2) and a third pin being disposed at the heel portion of the plate 2D. These pins are pr 'ily iornied integral with the sole plate and entend downwardly from the bottom thereof.
As best shown in Figure o, bosses 22 are formed integral with the bottom ci the base plate 10 and are perforated, as is also the base plate, as shown at 23 and 24, respectively, to slidably receive the pins 2i. A set screw 25 is threaded 70 through the side of each boss and bears against the corresponding pin. Loosening of the set screw permits oi the pin being raised or lowered to correspondingly adjust the sole plate whereupon the set screw may be tightened to hold 7 5 the sole plate in each adjusted position.
A toe strap 26, preferably formed of two pieces of leather and riveted, as shown at 27, to the sole plate, is laced together, as shown at 28, to comfortably enclose the toe of the wearers shoe and hold the jack firmly in place on the shoe. The strap is of sufficient width to maintain rm engagement with the shoe and at the same time allow the shoe to be slid in or out in minimum time and with minimum eiort so that the jack may be applied or removed in a jiiey.
From the above description it is thought that the construction and operation of my invention will be fully understood without further explanation.
What is claimed is:
1. A jack for workmen comprising aI base plate, runners on the bottoni side of the base plate, a sole plate, means for adjustably mounting the sole plate vertically on the base plate, 9 5 and means for securing the sole plate to the wearers shoe.
2. A jack for workmen comprising a base plate, resilient runners having dat treadsand having front and rear risers secured to the sole plate, braces connecting the runners with the base Y plate, the braces being crossed and resilient, a soleplate superposed above the base plate, pins extending downwardly from the sole plate, means for adjustably securing the pins to the base 195 plate, and a strap carried by the sole plate for C attaching the jack to the wearers shoe.
3. A jack for workmen comprising a base plate, lugs on the underneath face of the base plate,
a sole plate, pins extending downwardly from ,1,10
the sole plate and passing through the sole plate and the lugs, set screws threaded through the 4. A jack for workmen comprising a base plate,
resilient runners having at treads and having the ends curved upwardly and inclined` inwardly and riveted to the base plate, crossed braces riveted together at their crossing and havingY their ends riveted to the runners and to the base plate,
said braces being resilient, there being openings in the base plate, bosses surrounding said openings in the base plate, a sole plate, pins ex- `wearers shoe.
tending downwardly from the sole plate and passing through the openings in the base plate and extending through the bosses, set screws threaded through the sides of the bosses and engaging the pins for holding the sole plate in each adjusted position, and a toe strap carried by the sole plate for strapping the jack on the wearers shoe.
5. A jack for Workmen comprising a base plate, resilient longitudinal runners on the bottom of the base plate, a vertically adjustable sole plate carried by the base plate, and a toe strap carried by the sole plate for securing the jack to the DARCY D. KNOX.
