F, JUDD POST DRIVER Filed May 26, 1930 gPatented May 24, 1932 UNITED STATES PATENT OFFICE FRANK JUDD, F SAC CITY, IOWA, ASSIGNOR TO E. S. GAYNOB LUMBER COMPANY, OF
SIOUX CITY, IOWA, A CORPORATION OF IOWA POST DRIVER Application led Hay 26, This invention relates to an improved post driver.
An object of this invention is toprovide a post driver that is eflicient in its action and which is easily operated.
Another 'object is to produce a structure that shall avoid the transmission of the shock of the blow to the hands of the operator.
A further object is to so arrange the various parts of the post driver so that it shall be reinforced at certain desired point/s.'
Other objects' of my present invention will be apparent to those skilled in the art from the following description and appended claims.
In the drawings accompanying the description, j
Fig. 1 is a perspective view of my post driver in operative position on a post,
F ig. 2 isa top view of the post driver,
Fig. 3 is ayvertical section taken along line 3 3 of Fig. 2,
Fig. 4 is a section taken along line 4-4 of Fig. 3.
The driver consists of a guide tube 1 provided with a drivin@r weight 2 closing its upper end. The weight 2 is fastened in place by a rivet 3. On the outer side of the tube l adjacent the lower end of the Weight 2 an upper plate 4 is securely welded. The plate 4 in addition to its other functions described below serves to reinforce the tube 1 at this point. It is at this point that the tube 1 is subjected to the greatest strain. A lower plate 5 is provided which is of substantially the same size and shape as plate 4. Plate 5 however is provided with a central hole 6 which is larger than the tube 1 and thereby said plate 5 can slide freely over the tube 1.
Two side ends 7 are threaded at each end. The lower ends of these rods are screwed into two topped holes 8 in plate 5. Two nuts 9 and 10 serve to lock end rod 7 against movement Y relative to plate 5. Plate 4 is provided with two holes opposite the holes 8 of plate 3. These holes 11 are large enough to permit the ends of rods 7 to move freely through them. A tube 12 Vis placed over each rod 7 Between the upper end of each tube 12 and the plate 4, a spring 13 is provided. A sec- 1930. Serial No. 455,918.
To use the driver, the open end of tube 1 is Y of the tube and extending close to the bottom 'z thereof the driver is easily operated from the ground. The springs 13 and 14 serve to remove the greater part of the shock due to the impact of thev weight with the top of the post. Also upon the jumping ofthe weight after the initial blow the weight is guided to strike the top of the post a second time.
Various changes may be made in this emi bodiment of my inventlon as will be apparent to those skilled in the art Within the scope of the appended claims.
Having thus 'described my invention, I claim:
1. A post driver comprising a guide tube, a weight in the upper end of said tube, a plate secured to the outside of said tube at one end, thereof, operating handles resiliently connected to said plate, a second plate rigidly connected to said operating handles, the opposite endof said tube passing through said second plate.
2. A post driver comprising a guide tube, a weight in the upper end of said guide tube, a plate secured to the outside of said guide tube at one end thereof, said plate being provided with holes, a plurality of operating handles, one end of each of said handles passing freely through said holes, a shoulder on each of said handles both above and below said plate, a spring interposed between each of said shoulders and said plate, and means rigidly connecting the 'opposite ends of said handles.
3. A post driver comprising a guide tube, a Weight in the upper end of said guide tube,
aplate integral with said guide tube on the outside of said tube immediately adjacent the lower end of said weight and o rating handles resiliently connected to said plate.
6 4. A post driver comprising a uide tube,
a weight in the upper end of sai tube, latn eral extensions upon said tube at said upper end, long operating1 handles parallel w1t-h said tube passing t rough said extensions,
i@ resilient connections between said extensions and the upper part of said handles,and means for slidably connecting the lower part of said handles with said tube.
The foregoing specification signed at Sac 15 City, Iowa, this 17th day of Ma 1930.
