CARRlAG E-POLE ATTACHM ENT.

SPECIFICATION forming part of Letters Patent No. 707,439, dated August 19, 1902. Application filed February 8, 1902. Serial No. 93,194. (No model.)

To all whom it may concern:

Be it known that I, PATRICK MASTERSON, a subject of the King of Great Britain, residing at the village of Newington, in the county of Stormont, in the Province of Ontario, Canada,have invented a new and useful Improvement in Carriage-Pole Attachments, of which the following is a specification.

My invention relates to improvements in carriage-pole attachments; and the objectof my invention is to provide a means whereby the same carriage-pole may be used with different-sized buggies or carriages in summer or cutters or other sleighs in winter and by which the distance between the axle bearings or sockets and the distance from the axle center to the whifl'letree may be shortened or length ened simultaneously, and whereby the height of the carriage-pole may be varied to suit a high or low team of horses, and whereby the carriage-pole maybe adjusted very readily to the straight forward and central position; and a special object of my invention is to make such a device extremely light, strong, and cheap in construction; and it consists, essentially, of a pole of ordinary form having the end cross-piece attached thereto, side braces attached to the pole and the end cross-piece, said side braces having guideways formed on their rearward ends, and draw-rods adjustably held in said guideways,and means for securing said draw-rods in any desired position, the various parts being constructed and arranged in detail, as hereinafter more particularly described.

Figure 1 is a perspective view of my device, indicating in dotted lines the position of the draw-rods when extended. Fig. 2 is an enlarged perspective detail of the end of one of the braces and showing the end of the drawrod turned up into the position for use with a low team of horses and indicating in dotted lines the position of the draw-rod when the device is being used with a high team of horses.

1n the drawings like letters of reference indicate corresponding parts in each figure.

A is the pole, which is of ordinary form, being preferably slightly curved downwardly at its rear end.

B is a cross-arm at the end of the pole A. The pole A projects through a hole bin the crossarm and is secured thereto by means of the top and bottom T-pieces 19 b 0 O are side braces or stiffening-rods secured at one end to the pole A by means of bolts 0 o, and at their opposite ends they are formed with enlarged portions 0 c, which are bent in such a manner as to form guideways c c and flat portions 0 c Bolts 0 extend through the said fiat portions 0 c and secure the braces O O to the cross-piece B.

D D are slidably-adjustable draw-rods and are formed at their outer ends with hearings or sockets d d, which are designed to be secured to the axle or other part of the carriage or sleigh, as the case may be. The outer ends of these rods have a downward and inward curve at d when in the position shown in Fig. 1. In Fig. 2 one of these rods is shown reversed, so that its end curves upwardly and inwardly, and the latter is the position in which it is more especially adapted for use with a low team of horses. It will thus be seen that by simply interchanging the drawrods D D a difference of several inches may be made in the height of the pole, so that it may be adjusted to suit the height of the horses.

Recesses or holes 01 are formed on one or both sides of the draw-rods D, and set-screws d d extend through enlarged or thickened portions 0 c of the braces O and into holes or depressions 61*, the object of these setscrews being to secure the draw-rods D firmly in position, so that they cannot slip. The distance of each of the holes (1 from the end of one of the draw-rods is preferably the same as the distance of a corresponding hole from the end of the other draw-rod, so that the pole or shaft may be made perfectly central by simply getting the set-screw (i into corresponding holes on the two draw-rods.

E is the doubletree, which is pivotally held by a bolt a between a raised end of the T- piece I) and the pole A. i

It will thus be seen that I have devised a light, strong, and durable means for securing the pole of the carriage or sleigh to the axle or other portion of the vehicle, as the case may be.

I am aware that it is not new in pole attachments to provide means by which the same pole may be attached to carriages of ICC different width. I therefore do not claim such a device as my invention broadly; but the novel construction which I have employed has all the advantages of previous constructions in addition to certain advantages which they 'do not possess.

The principal features which my construction possesses are, first, that it gets rid of a number of unnecessary parts used in previous devices of this class, and consequently great cheapness and lightness are attained; second, it may be raised or lowered to suit high or low teams of horses by simply interchanging the draw-rods; third, the pole may be very readily adapted to the central position relative to the vehicle; fourth, the drawrod does not necessarily lie in the same direction as the line of the brace, so that the form of direction of the brace is not dependent on the direction of the draw-rod, but may be made of such a shape as is most desirable for strength and lightness. Further, in this connection it may be mentioned that the drawrods are entirely supported by the enlarged portion 0, which is very firmly secured to the cross-piece by bolts 0 and consequently the rest of the brace may be made very light, as it need only be sufiiciently strong to brace the pole and cross-piece, and no strain comes on it due to holding the end of the draw-rod.

What I claim as my invention is 1. The combination with the pole and crossarm, of a pair of converging draw-rods having suitable sockets at their rear ends, braces secured at their front ends to said pole and formed with enlarged portions at their rear I ends, said enlarged portions being bent to form guideways for said draw-rods, means for securing the outer ends of said braces to said cross-arm, and means for securing said draw-rods adjustably in said guideways as and for the purpose specified.

2. The combination with the pole and crossarm of a pair of draw-rods having suitable sockets at their rear ends, braces secured at their front ends to said pole and formed at their rear ends with enlarged portions said enlarged portions being bent to form guideways for said draw-rods, and flat portions to overlap said cross-arm, screws or bolts passing through said fiat portions and said crosspiece and set-screws extending through said enlarged portion of the braces to hold said adjustable draw-rods in position as and for the purpose specified.

3. The combination with the pole and crossarm, of a pair of adjustable draw-rods having recesses formed therein, the distance of each of said recesses on one rod from the end of its rod, being equal to the distance of a corresponding recess on the other rod from the end of its rod, braces secured at their front, ends to said pole and formed with enlarged portions at their outer ends, saidenlarged portions being bent to form guideways for said draw-rods and fiat portions to overlap said cross-arm, screws or bolts to secure said fiat portions to said cross-arm and set-screws extending through said enlarged portion and engaging the recesses in said draw-rods as and for the purpose specified.

Signed at the town of Cornwall this 4th day of February, 1902.

PATRICK MASTERSON.
