PERCl-ll CONNECTIION FOR VEHICLES.

Specification of Letters Patent.

Patented Nov. 14;, 1905.

Application filed May 29, 1905. Serial No. 262,929.

To ctZl whom it may concern:

Be it known that I, LESTER E. Hroxox, a citizen of the United States, residing at Mechanicsburg, in the county of Cumberland and State of Pennsylvania, have invented new and useful Improvements in Perch Connections for Vehicles, of which the following is a specification.

The object of my invention is the provision of improved means for securing a vehicle perch to an axle or to an axle and axle-bed, which means shall be simple in construction and comprised of few parts, which shall immovably hold the perch and axle in their relative positions, and which shall especially be adapted for forming a rigid connection when the reach is disposed obliquely to the length of the axle, as is common where two reaches are employed.

My invention consists in certain novelties of construction and combinations of parts as hereinafter set forth, and pointed out in the claims.

The accompanying drawings illustrate one complete example and one modification of the physical embodiment of my invention constructed according to the best modes I have so far devised for the practical application of the principle.

Figure 1 is a top plan view of a section of axle and axle-bed, a perch-heel, and a perch end, the parts being shown united. Fig. 2 is a side view in elevation. Fig. 3 is a bottom plan view of a perch-heel. Fig. 4 is a crosssection of Fig. 2. Fig. 5 is a side view of a modified construction.

Referringto the several figures, the numeral 1 designates the axle; 2, the axle-bed; 3, the perch; 4, the metallic strap located below the perch and commonly extending the entire length thereof, the said strap being provided with holes for the passage of bolts; 5, the top surface of the perch, which is curved in crosssection; 6, holes for the passage of bolts; 7, the perch-heel; 8, a groove with a surface curved in cross-section, said groove extending from the end to a point beneath the axle; 9, a seat adjacent to one end for the reception of the axle; 10, a hole for the passage of a bolt; 11, holes for the ends of the clip; 12, an offset or widened rear end of the perch-heel; 13, the clip; 14, the threaded bolt ends of the clip; 15, the bolt at the front end of the perchheel, and 16 the nuts upon the threaded bolt ends.

In Fig. 4 is shown the relative positions of the top curved surface of the perch and the bottom curved surface of the groove in the perch-heel prior to the tightening of the nuts upon the bolt 15 and upon the clip ends. It will be noted that only the longitudinal edges which bound the groove in the perch-heel are in contact with the curved longitudinal top edges of the perch and that a space 17 is present between the surfaces which are out of contact.

The relation of the curved surfaces of the perch-heel and perch may be expressed as follows: The radius by which is described the curve of the cross-section of the groove in the perch-heel is shorter than the radius by which is described the curve of the top surface of the perch. Upon tightening the nuts these surfaces are brought nearer together or larger areas thereof are brought into frictional contact. This feature of construction insures a very firm and immovable union of the perch-heel and perch and the certainty of a close frictional contact of the longitudinal edges bounding the groove with the top curved edges of the perch.

In Fig. 3 it will be observed that the offset portion 12 of the perch-heel is provided with a bolt-hole and that this hole lies at one side of a longitudinal straight line passing through the center of the perch-heel. This widened or offset portion of the heel is obviously necessary to allow the top surface of the axle-bed to be engaged by and fit the clip and at the same time to provide a hole for the passage of the rear bolt end of the clip.

Fig. 1 illustrates the top surface of the perch, located in a horizontal plane below the plane of the axle. \Vhen it is desired to locate the perch in a relatively higher plane, the construction may be modified, as illustrated in Fig. 5. The seat 9 is here made deeper, the groove 8 inclined to lit the beveled end of the perch, as shown by the full and dotted lines, and the metallic strap 4 extended to the end of the perch-heel and perforated to receive the rear bolt end of the clip.

The principle of the invention may be embodied in other forms and shapes, which will not constitute substantial departures.

VYhat I claim is 1. The combination in a perch connection,of an axle; a perch with a curved top surface; a perch-heel having a seat for the axle and a longitudinal groove in its under surface; a

clip with bolt ends; and suitable bolts and nuts; the cross-sectional curve of the groove in the perch-heel being such relative to the curved top surface of the perch that the longitudinal edges bounding the groove in the perch-heel will frictionally engage the top curved edges of the perch when the nuts are tightened upon the bolt and clip.

2. The combination in a perch connection,of an axle; a perch; a perch-heel widened at its rear end with a seat for the axle and a longitudinal groove in its under surface extended to a position beneath the axle to lit the top surface of the perch; a metallic strap; a clip with bolt ends; and suitable bolts and nuts; one bolt end of the said clip being passed through the perch-heel, perch and strap, and the other bolt end passed through the end of LESTER E. HICKOK.
