Application December 6, 1939, Serial No. 307,748
The present invention relates to supporting horses commonly called saw-bucks and more particularly to supporting horses of the knockdown type which may be assembled or knocked down as desired.
The primary objects of the instant invention are to provide an improved metal coupling for coupling the supporting legs and the cross bar of a supporting horse in rigid assembly; to provide such a coupling which is economical in manuiacture; to provide such a coupling which is compact in form; and, to provide such a coupling which is efficient in its intended use.
An illustrative embodiment of the invention is shown in the accompanying drawing, wherein:
Figure 1 is a side elevational view of a supporting horse assembled for use by means of a pair of my improved metal couplings;
Figure 2 is an end elevational view of the same; and
Figure 3 is an enlarged perspective View of a metal coupling per se.
Referring to this drawing wherein like parts of the supporting horse and its couplings are designated by the same numerals in the several views, my improved metal coupling for a supporting horse comprises a cross-sectionally U-shaped body member l having a horizontal medial portion II and upstanding leg portions I2 with aligned notches I3 therein formed by striking flanges l4 horizontally outwardly from the said leg portions 12 at the bottom of the notches i3. These aligned notches l3 form a socket for the reception of an end of the cross bar [5 of the sup-porting horse.
A pair of U-sh-aped yokes l6 are preferably formed separately from the body member ID and are each thereafter welded to the body member on opposite sides thereof, the leg portions ll of each yoke [5 being welded as indicated at 13 to the leg portions [2 respectively of the body member H3.
The medial portion IQ of each U-shaped yoke I6 is inclined downwardly-outwardly with respect to the body member In, and eachyoke 16, with the medial portion ll of the body member ID, forms a socket extending upwardly-inwardly to intersect with the horizontal socket in which the cross bar I5 is disposed.
The upper end portions of supporting legs 20 adapted to support the horse l5 are received in the inclined sockets formed between the yokes l6 and the medial portion H of the body member Ill and the upper extremities of said supporting legs 20 are in abutting engagement with the cross bar 15.
It will thus be seen that the cross bar I5 is tightly wedged between the pairs of supporting legs 29 at the opposite ends of the supporting horse and that downward force applied to the cross bar [5 serves to wedge the parts together in even more rigid assembly.
It will be further seen that the metal coupling herein shown and described may be economically made of stamped and bent sheet metal and that no waste of sheet metal occurs in such manufacture since the flanges it serve as supporting ledges for the cross bar I5 thereby eliminating any sharp edges at the bottom of notches [3 which sharp edges would cut into the cross bar [5.
While but one specific embodiment of the invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted without departing from the spirit of the invention as the same is defined by the following claims.
1. A supporting horse coupling comprising a cross-sectionally U-shaped member whose upstanding leg portions are each provided with a transverse notch each in alignment with the other for the reception of a cross bar, and a pair of U-shaped yokes secured to said body member at opposite sides thereof respectively, each U-shaped yoke having its leg portions secured to the leg portions respectively of the body member and each having its medial portion inclined downwardly-outwardly with respect to the body member, and each yoke being adapted to embrace the upper end portion of a supporting leg between said yoke and the medial portion of the U-shaped body member for maintaining the upper extremity of said supporting leg in abutting engagement with said cross bar.
2. A supporting horse coupling comprising a cross-sectionally U-shaped body member whose upstanding leg portions are provided with aligned notches for the reception of a cross bar, flanges on said leg portions extending horizontally outwardly from the bottoms of said notches, and a pair of U-shaped yokes secured to said body member at opposite sides thereof respectively, each U-shaped yoke having its leg portions secured to the leg portions respectively of the body member and each having its medial portion inclined downwardly-outwardly with respect to the body member, and each yoke being adapted to embrace the upper end portion of a supporting leg for maintaining the upper extremity of said supporting leg in abutting engagement with said cross bar.
