WILLIE AMOS BOYNTON, OF DUBLIN, TEXAS.
SHAFT-IRON.
SPECIFICATION forming part of Letters-Patent No. 629,980, dated August 1, 1899.
Application filed August 1 7, 1898. Serial No. 688,781. (No model) To ctZllui'wm it may concern.-
Be it kn own that I, WILLIE Amos BOYNTON, a citizen of the United States,residing atDublin, in the county of Erath and State of Texas, have invented a new and useful Shaft-Iron, of which the following is a specification.
The invention relates to improvements in shaft-irons.
The object of the present invention is to improve the construction of shaft-irons and to increase the strength, durability, and efficiency of shafts and at the same time to cheapen the construction of the same by dispensing with the curved rear ends.
A further object of the invention is to strengthen the connection between the shafts and the-cross-bar and to enable any one to replace readily a broken shaft.
The invention consists in the constructionand novel combination and arrangements of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.
In the drawings, Figure 1 is a perspective view of a portion of a shaft and a cross-bar provided with a shaft-iron constructed in accordance with this invention; Fig. 2 is a longitudinal sectional view. Fig. 3 is a transverse sectional view. Fig. 4 is a detail perspective view of the shaft-iron.
Like numerals of reference design ate corresponding parts in all the figures of the drawings.
1 designates a shaft-iron constructed of suitable metal-such as malleable iron, steel, or the like-and provided at its rear end with an eye 2, adapted to receive the pivot of a thin-coupling in the ordinary manner.
The shaft-iron, which is hollow and halfround, fits on the upper face of a shaft 3 and is curved, as shown, and thereby obviates the necessity of curving the rear end of the shaft, which may be made perfectly straight. It affords a shield for the rear end of the shaft, and as the shaft is straight it may, in case of breakage, be replaced byany one,which could not be the case were its rear end curved in the usual manner.
The shaft-iron is provided with a tubular half-round extension 4, arranged at right angles to it and fitting over the upper face of one end of a cross-bar 5, which connects a pair of shafts in the usual manner.
The shaft-iron is secured to the shaft and the cross-bar by means of bolts 6, which pass through the parts and also through a T-shaped bottom plate 7 Nuts 8 are arranged on the lower threaded ends of the bolts and engage the T-sh aped bottom plate, and the construction is further supported by an inclined brace 8*, extending from the lower or rear end of the shaft-iron to the lower face of the shaft at a point slightly in advance of the crossbar. The brace consists of a rod and has its ends flattened and perforated to receive one of the bolts 6 and a bolt 9, which passes through the lower end of the shaft-iron.
The upper faces of the shaft 3 and the cross bar 5 are recessed to receive the shaft-iron,
which has its upper face flush with those parts, and the shaft may, if desired, extend downward to the solid rear end of the shaft- The invention has the following advantages: The shaft-iron, Which is simple and comparativelyinexpensive in construction, possesses great strength and durability and affords a firm connection between the cross-bar and 'the shaft, and as it is located at the upper faces of the same it serves as a shield to protect the joint from the weather. The shaftiron greatly cheapens the construction of shafts by dispensing with the curved rear ends which are usually employed, and by employing a straight shaft it will, in-case of breakage, require but a small amount of workmanship to replace it.
What is claimed is- In a device of the class specified, the combination with a shafnand a connecting crossbar, of a shaft-iron secured to the inner end portion of the shaft and having its rear portion curved downwardly and having an 0% standing portion a short distance from its front end the main body and offstanding portion' being curved upwardly between their edges and being hollow, and the shaft and cross-bar being grooved to receive the shaftiron and the recesses beingof a depth to bring the shaft-iron parts flush with the shaft and cross-bar, and a T-plate adapted to engage the under sides of the shaft and cross-bar re spectively, a series of bolts passing through the shaft-iron, the shaft and the cross-bar, a brace having an opening at its forward end to receive one of said first-mentioned bolts and having an opening at its opposite end, and a bolt passing through the extreme rear end of the shaft-iron and also through said rear opening in the brace, substantially as 10 described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
WILLIE AMOS BOYNTON.
