Jan. 15, 1957 L. J. ZENT TRACTOR MOUNTED SUPPORT FOR UMBRELLAS Filed Dec. 22, 1955 nvmvrox J T A United States Patent TRACTOR MOUNTED SUPPORT FOR RELLAS Lawson J. Zent, Huntington, Ind., assignor to The Hettrick Manufacturing Company, Toledo, Ohio, a corporation of Ohio Application December 22, 1955, Serial No. 554,855
1 Claim. (Cl. 248-41) This invention relates to mountings for umbrellas for farm tractors or the like and an object is to produce a new and improved mounting of this character, which can be readily installed on dilferent make tractors and is simple and inexpensive to manufacture.
Other objects and advantages of the invention will hereinafter appear and for purposes of illustration but not of limitation, an embodiment of the invention is shown on the accompanying drawings, in which Figure 1 shows a rear perspective view in broken lines of a farm tractor, showing the umbrella pole mounting installed thereon, a portion of the umbrella pole being shown but the umbrella itself being omitted;
Figure 2 is an enlarged side elevation of the umbrella pole mounting, showing a portion of the umbrella pole mounted therein;
Figure 3 is a transverse sectional view of a portion of the umbrella pole mounting showing particularly one of the C-clamps with its brace tube mounted thereon; and
Figure 4 is a sectional view through the umbrella pole mounting tube and showing particularly the C-clamp and bracket for the base of the tube.
The illustrated embodiment of the invention comprises a farm tractor T which has a seat S at the rear for the operator and has an umbrella (not shown) arranged over the seat for shielding the operator, the umbrella having an upright pole P, the lower end of which seats in a vertical supporting tube which may be of metal or other suitable material. The upper end of the tube is split vertically for a short distance as indicated at 11 and a C-clamp embraces the split upper end, the clamp having a. thumb-screw 13 for tightening the split end portion about the lower end of the umbrella pole for holding the latter rigidly in place.
Mounted on the supporting tube is a pair of similar C-clamps 14. These clamps may be disposed at difierent positions axially of the supporting tube as the circumstances require with the particular tractor on which the umbrella pole mounting is installed. Manifestly, these clamps may be placed close together or widely separated depending upon the structure of the tractor and where the brace rods or tubes may be conveniently secured. Each of the C-clamps 14 has a pair of flanged ends 15 which are transversly apertured to receive a bolt 16, the head 17 of which abuts against the outer end of one of the flanges and the opposite end portion of the bolt extends outwardly beyond the opposite flange to receive a somewhat smaller O-clamp 18, similar to the C-clamp 14 so that it can swivel about the bolt 16 to enable convenient adjustment. A nut 19 on the outer end of the bolt 16 may be tightened to secure these parts firmly together. Extending through the C-clamp 18 is an elongate brace 20 in the form of a tube which has a lower flattened end 21 formed with a hole 22 to enable this end of the brace tube to be rigidly secured to a frame part of the tractor T. In practice, the brace tube 20 is furnished somewhat longer than would normally be required so that the tube can be slipped in or out of its supporting clamp and after the proper position of attachment has been reached, the opposite end can be sawed 0E. Manifestly for some tractors a relatively long brace rod or tube is required whereas on other tractors, a much shorter brace will be needed so that by providing the braces of generous length, that portion which is not required may be sawed oil.
It will be manifest that the C-clamps above described enable a fairly complete universal mounting to be effected because the clamps 14 may be oriented about the supporting tube 16 to the desired position and since the bolts 16 are at right angles to the axis of the supporting tube, the brace rods or tubes 2% may be adjusted to any convenient position as required to efiect a rigid and secure mounting on a part of the tractor.
For securing the base of the supporting tube 10, a G-clarnp 23 similar to the clamp 14 above described has a bolt and nut assembly 24 and an L-shaped bracket 25 has one end apertured to receive the bolt so that it may be secured by the bolt and nut assembly 24, the opposite end being apertured at 26 to enable it to be attached to a part of the tractor frame. Manifestly the bracket 25 may be rocked about the bolt as a pivot to enable it to be adjusted for convenient attachment to the tractor, thereby to hold the base of the supporting tube in the desired position.
It will be clear upon the above description that the brace rods 20 may extend in opposite directions so as to support the tube 18 rigidly from a lateral standpoint and with the base clamp 23 rigidly secured in place, the umbrella pole supporting tube is satisfactorily held securely in an upright position.
Numerous changes in details of construction, arrangement and operation may be effected without departing from the spirit of the invention, especially as defined in the appended claim.
What I claim is:
An umbrella pole mounting for farm tractors comprising an upright tube adapted to receive the lower end of the umbrella pole, a base strap clamp on the base portion of the tube, a bracket carried by said base strap clamp for rigid attachment to the tractor frame, a pair of brace strap clamps on said tube above said base clamp, each of said brace strap clamps having a pair of end portions with aligned apertures extending therethrough, bolts extending through the apertures in said end portions, each of said bolts extending beyond one of the respective clamp end portions, a smaller strap clamp on each of said projecting bolt ends and a brace arm extending through each of the smaller strap clamps, the smaller strap clamps having end portions with aligned apertures extending therethrough and through which said bolts respectively extend, a nut on each of said bolts thereby to secure and tighten said brace arms, brace clamps, and smaller strap clamps, the lower end of each brace arm being adapted to be rigidly attached to a tractor part, whereby said brace arms may be selectively afiixed in various directions for rigidly holding said supporting tube in upright position against lateral movement.
