SAMUEL H. HAAS, OF PHILADELPHIA, PENNSYLVANIA.

SHAFT-TUG.

SPECIFICATION forming part of Letters Patent No.471,818,`dated March 29, 1892.

Application filed J'nly 15, 1891. Serial No. 399,582. (No model.)

To all whom t may concern,.-

Be it known that I, SAMUEL H. Hans, a citi-- zen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Shaft-Tilgs, of which the following is a specification.

One object of my invention is to so construct a shaft-tug for harness as to prevent the chaiing or abrading of the shaft by the tug, a further object being to provide for the attachment of the tugto the saddle-strap without the employment of. the usual buckle. These objects I attain in the manner hereinafter set forth, reference being'had to the accompanying drawings, in which- Figure 1 is a perspective view of the shafttug constructed in accordance with my invention, and Fig. 2 is a longitudinal sectional view of the same.

The tug consists, essentially, of a shaft-supporting hook A and a spring-tongue B, closing the mouth of the hook, this tongue in the present instance being hung to a transverse pin a and acted on by'a spring b, which tends to close it, but permits of its movement to the position shown by dotted lines in Fig. 2, in order to provide for the introduction or withdrawal of the shaft, which is shown by dotted lines in Fig. 2. The hook A is open at the rear, but has opposite cheek-pieces d, connected by transverse pins f and g, the pin f receiving the looped upper end of the bellyband D and the pin g serving as a bearing for the saddle-strap F, which has a series of openings t', to any one of which may be adapted'a projecting pin m on a cross-bar m ofA the hook, as shown in Fig. 2. The upper end of the spring-tongue B has an opening for the reception of the projecting pin m, and into this opening projects a depending finger ot, which serves to bear upon the saddle-strap and prevent the same from slipping outwardly on the said pin m to such an extent as to be released therefrom, that portion of the saddle-strap which is below the pin g being retained in position by being tucked between the band D and the bottom of the hook A, as shown in Fig. 2, so that the traces cannot catch upon said lower end of the strap. The springtongue B of the tug has on the back adjacent to the lower end or point a rearwardly-projecting toe p, which by contact with the top of the shaft serves to prevent the rise of the latter in the tug, and thus precludes any jamming of the shaft in the tapering space formed by the spring-finger and the back of the hook, chating or abrasion of the top and upper corners of the shaft being thus effectually prevented, while the strap F projects forward' beyond the cheek-pieces d, and thus prevents contact of the inner side of the shaft with the latter.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. The combination of the hook having a projecting pin at the upper end with the spring-tongue closing the mouth of the hook and having an opening` for the reception of said pin and a depending finger projecting into said opening toward the pin, substantially as specified. l

2. The combination of the hook having cpposite cheek-pieces atthe rear, a springtongue closing the mouth of the hook, a pin projecting from the upper portion of the hook and adapted to an opening in the saddle-strap and to an opening in the tongue, and a transverse pin forming a bearing for said saddlestrap below the retaining-pin', substantially as specified.

3. The hook having a spring-tongue7 an open back with opposite cheek-pieces, a projecting pin, and a bar for receiving the bellyband, said bar occupying such relation to the" inner edges of the cheek-pieces that when the saddle-strap is passed downward between the belly-band and the bottom of the hook said strap will project forward beyond the cheekpieces of the latter, substantially as specified. In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.
