SPRING OILER APPLICATION FILED 001'. 1, 1921.-
ATTORNEY JACOB K. HEBFJORD, 0F SIOUX CITY, IOWA.
Specification of Letters Patent.
Patented Apr. 111, 11922.
Application filed October 1, 1921. Serial No. 504,703.
To all whom it may concern:
Be it known that I, JAoon K. HERFJORD, a citizen of the United States, and a resident of Sioux City, in the county of Woodbury and State of Iowa, have invented certa n new and useful Improvements in Spring @11- ers, of which the following is a specificatlon.
My invention aims to provide an improved device for greasing vehicle springs.
Another object of the invention is the pro duction of an improved and simplified device, inexpensive in production and adapted to be readily inserted between ad acent leaves of vehicle springs and inject grease thorebetween.
With these and other objects in view, the invention, consisting in the construction, combination and novel arrangement of parts, will be clearly understood from the following description, reference being had to the accompanying drawings, which form a part of this application and in which like characters of reference indicate corresponding parts throughout the several views, of which:
Fig. l is a plan of a device constructed in accordance with my invention.
Fig. 2 is a side elevation thereof, and
Fig. 3 is a longitudinal section thereof as applied to a vehicle spring.
The device consists of a bar, 4-, preferably flat-sided and formed at one end with a chisel blade, 5, the bar being cut away abruptly to provide shoulders, 6, which abut the edges of the springs, as will presently appear, and adjacent the said shoulders the blade, 5, is formed with flat faces, 7, against which the springs impinge. A distance from its chisel end the bar is provided with a lateral opening, 8, into which is threaded the nipple, 9, of a grease cup of familiar type, and on to the body, 10, of which is screwed the usual cap or cup, 11. The center of the end of the bar, 5, is notched, as at 12, and a longitudinal grease-way, 13, within the bar, 4t, communicates between the openin 8, and the said notch, 12.
Now, in operation it is only necessary to place the edge of the bar, 5, between adjacent leaves of the spring and the blade driven between the said leaves by means of a single blow on the extended end of the bar, l, with a hammer or other suitable tool. T he shoulders, 6, engage the edges of the leaves to prevent the blade from entering too far between the leaves. It will then be clear that by rotating the cap, 11, the grease will be forced through the passage, 13, and thus introduced between the leaves.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is
A greasing device for vehicle leaf springs comprising a bar having a chisel-bladed end to be driven between the leaves, a grease injecting cup including body part having a nipple screwed into the side of the bar, and a cover member in screwthreaded connection with the body, whereby rotation of the cover ejects grease from the nipple, and a greaseway in the bar between the nipple and said bladed end.
In testimony whereof, I have hereunto set my hand this 28th day of September, 1921.
JACOB K. HERFJORD.
