HAROLD W. RANDALL, OF QUIMBY, IOWA.
POLE-TIP.
Application filed January 21, 1913.
Specification of Letters Patent.
Fatented Dec. 9, 1913.
Serial No. 743,308.
To all whom it may concern:
Be it known that I, HARoLD W. RANDALL, a citizen of the United States, residing at Quimby, in the county of Cherokee and State of Iowa, have invented certain new and useful Improvements in Pole-Tips; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to the tips for the draft poles of vehicles provided with springactuated catches for holding the rings of the neck-yokes in place; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a longitudinal section through a pole tip constructed according to this invention. Fig. 2 is a cross-section taken on the line 12-00 in Fig. 1. Fig. 3 is a plan View of the spring-actuated catch.
The pole tip consists of a tapering metallic tube 2 adapted to be secured over the end portion 3 of the draft pole of a vehicle. This tube is provided on the rear part of its lower side with an inclined plate A for the ring of the neck-yoke to bear against, and it has a slot 5 in its lower side at about the middle of its length. A pin or rivet 6 is passed horizontally through the front end portion of the tube 2. A catch 7 provided at its front end with a bearing sleeve 8 is pivoted on the pin 6, and projects rearwardly in the tube 2 and is provided at its extreme rear end with a tooth 10 which projects downwardly through the slot 5 at a little distance in front of the plate 4. The front side 11 of this tooth is inclined and its rear side is substantially vertical. The spring for actuating the catch is formed of wire and is provided with helical coils 14: which are wound upon the end portions of the sleeve 8 on each side of the catch. The
spring has a short loop 15 at its middle part which rests on the catch a little in front of the sleeve 8, and it has straight portions 16 at its ends which project rearwardly in the tube and bear against its upper side.
When the ring of the neck-yoke is slipped onto the pole tip it raises the catch, and the catch retains it in place until the catch is raised by hand. When constructed as hereinbefore described the free end portion of the catch does not have to be raised for more than one half the diameter of the tube, and the spring is not liable to be broken as it is not subjected to any severe strain. The ends of the sleeve 8 bear against the sides of the tube and hold the catch centrally in the tube, and the sleeve permits the catch to move pivotally with very little friction. The coils of the spring are of ample size as they are wound upon the sleeve and do not come in contact with the pin.
What I claim is:
In a pole tip, the combination, with a tube having a projection at its rear part and a slot at its middle part, of a pin secured crosswise of the center of the tube at its front end, a catch having a sleeve at its front end which is pivoted on the said pin and which extends between the sides of the tube, said catch having a retaining tooth at its extreme rear end which projects downwardly through the said slot, and a spring provided with helical coils which encircle the end portions of the said sleeve, said spring having a short loop at its middle part which bears on the catch close behind its sleeve, and having straight portions at its ends which project rearwardly and bear against the top of the tube.
In testimony whereof I have afixed my signature in the presence of two witnesses.
HAROLD W. RANDALL.
