WILLIAM REMIGH, OF SINKING SPRING, PENNSYLVANIA.

SHAFT AND 'II-IILL IRON. I

Specification ofLetters Patent.

Patented Dec.- 24, 1907'.

Application filed September 26,1907- Serial No. 394,729.

To all whom it may concern:

Be it known that I, WVILLIAM REMIOH, a

citizen of the United States, residing at Sinking Spring, in the county of Berks and State 1 of Pennsylvania, have invented a new and i useful Improvement in Shaft and Thill Irons,

of which the following is a specification.

This invention is a new and improved construction of shaft and thill irons, the object being to provide an exceedingly strong and 3 tween the truss frame and shafts.

stated the upper bar D is curved preferably durable connection between the axle and end of the shaft and which will entirely obviate the necessity of using curved or bent wood in the construction of shafts or thills.

coupling carried by the axle, the innermost portion being braced for the purpose of providing additional strength and the invention consists also in the employment of a supplemental diagonal brace to prevent lateral strain.

tails of construction all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming a part of this specification, Figure 1 is a detail perspective view showing my improved form ofshaft or shaft or thill, a portion of the cross piece being also shown.

securely fasten the parts together. It will be noted that the upper and lower bars extend a considerable distance forwardly upon the upper and lower faces of the shaft or thill thereby providing a very firm connection be- As before in the arc of a circle and adjacent its rear and lower end it is bent or looped horizontally as shown at D and the lower and rear end of the bar E is bent or looped horizontally as shown at E and it will be noted that the bend or loop D is downwardly while the bend or loop E is upwardly and furthermore the bend or loop E fits within the bend of loop D, a sleeve or bearing being provided through which the thill bolt can be passed and in order to maintain these bends in their proper positions I pass a short bolt G through the said bends as most clearly shown in Fig. 1.

For the purpose of bracing the truss frame,

I employ a strut or bridge piece II which may 3 be of wood or metal and which is held in po- 3 sition by'means of a bolt H passing through The invention consists also in certain de- 5 the upper and lower bars and the strut or bridge. In order to prevent lateral strain and also brace the connection between the end of shaft and cross piece, I employ an angular brace I, the horizontal member I being bolted to the under side of the cross l pie'ce while the oblique member I extends thill iron connected to the rear end of the Fig. 2 is a bottom plan view of the iron together with the rear end of i the thill and adjacent end of the cross piece. Fig. 3 is a detail sectional view.

In the practical application of my invental brace K extends across the angle formed between the ends of the shaft and cross piece I and it will be noted that this supplemental tion I employ the usual or any approved construction of shaft or thill A being exactly alike and connected at their rear ends by means of a cross piece B, said connection be- 5 ing preferably made by means of a mortise and tenon joint. It will be noted that the end of the shaft or thill is not curved downwardly as commonly done but connected to the rear end of the shaft or thill is .a truss frame C comprising upper curved bar D and a lower straight bar E, said bars D and E being l l l l l preferably constructed of a good quality of steel. inserted between the forward ends of the bars D and E and carriage bolts F serve to The rear end of the shaft or thill A is l piece is secured in position by means of the bolts which serve to secure the main brace to the cross piece and the shaft irons to the shaft. By means of a connection such as herein shown and described the shaft A can be quickly and easily detached whenever desired and another shaft inserted in its place. Furthermore in shipping the shafts, the iron frames can be dismembered and packed into a very small space thereby saving a great deal of space during shipment and the parts can be quickly and easily assembled whenever desired.

A shaft connection construction as herein shown and described is exceedingly strong and durable and provides a very convenient connection at the point where strength, duor looped ends of the upper and lower bars rability and elasticity are most needed.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is z I 1. A shaft connection comprising the upper curved bar and the lower straight bar, the rear ends thereof being bent or looped and adapted to fit one within the other,

means for fastening said bent or looped ends together, means for connecting forward ends to the shaft or thill and the intermediate having its rear end fastened within the bent 3 as specified.

3. The combination with a shaft and cross piece, of the upper curved bar bent downwardly at its rear end, the lower straight bar bent upwardly at its rear end and fitting within the bend at the end of the upper bar, the intermediate strut or bridge piece, the angular brace having its rear end secured within the bend of the upper and lower bars, and the horizontal member of said brace being connected to the bottom of the cross piece, and the supplemental brace connecting the shaft and cross piece and also the brace and bars together with bolts for fastening the said parts together as specified.
