EXTENSlON POLE FOR CARRIAGES.

SPECIFICATION forming part of Letters Fatent No. 390,395, dated October 2, 1888.

Serial No. 271,059. {No model.)

To aZZ whom it may concern.-

Be it known that I, CALVIN E. PERRY, a citizen of the United States, residing at Leicester, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Extension-Poles for Carriages, and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

My invention relates to poles for carriages, sleighs, &c., and more particularly to that class of poles designated by the term extensionpoles, which are adapted to be adjusted so as to fit and be applied to carriages and sleighs of different widths; and my invention consists in certain novel features of construction of an extension-pole having for its purpose to cheapen and simplify the ordinary construction thereof, and at the same time to add strength and rigidity to the several parts and prevent any looseness or rattling of the same.

Referring to the drawings, Figure 1 is a plan view of my improved extension-pole. Fig. 2 is a side view looking in the direction of arrow (4, Fig. 1; and Fig. 3 is a detached section taken at line X X, Fig. 2, looking in the direction of arrow 1), same figure.

In the accompanying drawings, 1 is a portion of the pole proper, shown broken off, which is made of wood and preferably straight, without the usual downward curve at its rear end, as is customary in poles for carriages as ordinarily constructed.

Bolted to the rear end of the pole 1 are the pole-supporting arms 2 2, which are bent downward and outward, as shown in the drawings. Said supportingarms 2 2 carry at their outer ends the hub or barrel 3, and a straight brace, 4, extends from said hub and is bolted to the pole 1 in front of the doubletree 5, for the pur' pose of strengthening the pole.

In each hub 3 is rigidly supported and secured a spindle, 6. Said spindle 6 is preferably made with a shoulder, 6, and has the end which extends through the hub 3 screwthreaded and provided with a nut, 7, for securely holding the spindleG in its supportinghub.

Supported upon the spindle 6, and adapted to slide thereon, is the thill-iron 8, having the eye 8. The end of the thill-iron 8 which fits on the spindle 6 is preferably split and adapted to be brought together to secure the thill-iron Sin any desired position on the spin die 6 by a bolt, 9, and a nut, 10.

By means of the bolt9is pivotally connected with the split end of the thill-iron 8 one end of a tie-rod or adjustable brace, 11, which fits into a slot in the end of said thill-iron. lhe other end of the adj ustablc brace 11 is attached to the brace 4 by means of a hook-bolt, 12, which partially encircles and is adapted to slide on said brace 4. The shank of the hookbolt 12 extends" through a hole in the end of the adjustable brace 11, and by means of a nut, 13, the hook-bolt 12 and the brace 11 are clamped to the brace 4 at any desired point.

From the above description, in connection with the drawings, the operation of my improved extension-pole will be readily understood by those skilled in the art.

If it is desired to narrow the pole, the nuts 10 and 13 are loosened and the thill-irous 8 moved intoward each other, causing the rods 11 to slide on the braces 4, as indicated by dotted lines, Fig. 1. The nuts 10 and 13 are then tightened to hold the thill-irons securely in place.

By means of the adjustable tie-rods or braces 11, extending from the thill irons to the braces 4, I am enabled to use a round spindle, 6, for supporting the thill-irons 8 and to prevent any turning of the thill-irons on said spindle. At the same time I transfer the bulk of the draft from the spindles 6, which are liable to become bent, to the braces 4.

It will be understood that the details of the construction of some of the parts of my improved eXtension-pole may be varied somewhat from what is shown and described without departing from the principle of myinvention. For example, the rear end of the pole 1 might be curved downward and the supporting-rods bent to correspond.

Instead of a hookbolt, 12, for attaching the end of the adjustable tie-rod 11 to the brace 4, a clevis or other equivalent device could be used. A set-screw might be used for securing the thill-iron 8 on the spindle 6 instead of the bolt 9 and nut 10.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the pole l, supporting-rods 2, extending downward and outward from the rear end of said pole, hubs 3 at the ends of said rods 2, and spindles 6, secured in said hubs, of braces 4, extending from the pole 1 to the hubs 3, thill-irons 8, supported and adjustable laterally upon spindles 6, and adjustable tie-rods l1, connecting the thilldrons 8 with the braces 4, and means for securing said thill-irons and tie-rods, sub stantially as shown and described.

2. The combination, with pole 1, support- 20 ing-rods 2, hubs 3 at the ends of said rods, braces 4, extending from said hubs to the pole 1, and spindles 6, secured in said hubs 3, of thill-irons 8, having eyes in their outer ends, and their inner ends split and adj ustablysupported on the spindles 6 and adapted to be clamped thereon, and tie-rods 11, pivoted at one end to the thill-irons 8 and adj ustably connected at their other end with the braces 4, and adapted to be clamped thereto, for the 30 purpose stated, substantially as shown and de scribed.

CALVIN E. PERRY.
