m l A EDWIN N. ROBINSON, OF HOT SPRINGS, SOUTH DAKOTA.

POLE-TIP.

Specification of Letters Patent.

Application filed March 16, 1909.

Patented June 14, 1910.

Serial No. 483,754.

T 0 all whom it may concern:

Be it known that I, EDWIN N. ROBINSON, a citizen of the United States, residing at Hot Springs, in the county of Fall River and State of South Dakota, have invented a new and useful Improvement in Pole-Tips.

My invention relates to that class of attachments, secured to the tip of a carriage pole, or wagon tongue, whereby the neck yoke is properly secured to the pole, in such a manner that the neck yoke, while being securely held against accidental displacement, may be instantly removed, by operating a leaf spring, as will be described more fully hereinafter.

In the accompanying drawings, I show in Figure 1, a front view of a pole tip, provided with my tip, while Fig. 2, shows a central sectional view, disclosing the position of the neck yoke ring.

In carrying out the object of my invention, I construct a pole tip, comprising the upper plate 3, having two rivet openings to receivethe

rivets

13 and 14, as clearly shown in Fig. 1. In front this upper plate is reduced, and continued in the draft loop 2, from which extends the lower plate 4. This lower plate also has two rivet openings, to receive the

rivets

13 and 14, and is further provided with the forwardly extending hold back 10, and the ear 5. The rivets pass tihrough the tip of the pole 1, as shown in The hold back 10, is provided with a socket to snugly receive the neck yoke ring 15, and in front has a depression 12, forming a seat, within which is held, the end of a J-shaped spring member 9. This J-shaped spring is provided with a voluted end 5, of a width to snugly fit into the recess 6, of the ear 5. The termination of the shorter end 8, of this J-shaped spring, rests within the cavity 7, formed within the bottom plate 4, near the recess 6. This spring is of such a length, that when the voluted end 5, is within its recess, the end of the longest member of the spring, snugly fits into the seat 12, as shown. From this it will be seen that the voluted end 5, as well as both of the ends of the spring are held within suitable sockets, preventing any displacement of the spring, after once being forced into position.

The distance between the lower plate 4, and the spring leaf 9, is of such a width, that when the ring 15, secured to the neck yoke, is carried forward, this ring will be in frictional contact with this spring member 9.

My device insures a neat, serviceable pole tip. Under force, the spring, as well as the neck yoke ring can be replaced.

The hold back 10, it will be noticed, ex-

tends forwardly from the lower plate 4, and

is positioned intermediate between the ends of said plate. The voluted end 5, insures proper resilience.

Having thus described my said invention, that which I claim as new, and desire to secure by U. S. Letters Patent is- 1. A pole tip comprising an upper plate, continued to form a draft loop, from which extends a lower plate, provided near the forward end with a recessed ear, said lower plate near the recess of said ear having a cavity, a forwardly extending hold-back projecting from said lower plate intermediate between its ends, said hold-back having a seat within its tip, and a J-shaped spring having a voluted end, the end of the longest member of said J-shaped spring resting in said seat, the shorter spring end resting in said plate cavity, said voluted spring end being held within the recess of said ear, all arranged as described.

2. A pole tip comprising an upper and lower securing plate united at their forward ends by means of a curved draft loop, said lower plate having a cavity near its forward end, a hook-shaped hold-back extending forward from near the rear end of said lower plate having a seat, an ear with a recess extending from said lower plate in alinement with said hold-back, a J-shaped spring provided with a voluted end held within said recess, the shorter end of said J -shaped spring resting within said cavity, the longest end of said spring normally held within said seat.

In testimony whereof I aflix my signature, in presence of two witnesses.

EDWIN N. ROBINSON.
