DEVICE FOR REMOVING AND INSTALLING SPRINGS Filed Oct. 14 1929 2 Sheets-Sheet 2 Inventor A itomey Patented May 5, 1931 i UNITED STATES A ENI OFFICE A HARRISON DBODDY, or EL noRAno, ARKANSAS, ASsIGNoR OF oNE-IIALR ro JACK Rome, on EL DORAIDO, ARKANSAS I DEVICE FOR REMOVING AND INSTALLING SPRINGS Application filed October 14, 1929:. Serial No. 399,542.

The present invention relates to a device for removing and installing springs particularly those of the transverse type now in common use and the prime object of the invention resides in the provision of an apparatus whereby the spring may be flattened out to an extended position or held in this position during the installation or removal thereof thereby making this operation comparatively easy.

Another very important object of the invention resides in the provision of an apparatus of this nature which is exceedingly simple in its construction, inexpensive to manufacture, strong and durable, easy to assemble and disassemble, easy to operate, thoroughly efficient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement ofparts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is an elevation of one type of spring upon which the apparatus may be used to advantage,

Figure 2 is a top plan view of the spring with the apparatus associated therewith,

Figure 3 is an end view of the connecting bar,

Figure 1 is a perspective view of one of the lin s F igure 5 is an elevation of the spring and apparatus showing the operating means removed,

Figure 6 is a detail elevation of the connecting bar,

Figure 7 is a detail elevation of one of the jacks, and a Figure 8 is a detail Section taken substantially on the line 8-8 of Figure 7.

Referring to the drawing in detail it will be seen that the letter S denotes a somewhat semi-elliptical or upwardly i bowed spring such as is commonly in use on automobiles and is provided at its ends with eyes 5.

The numeral 6 denotes a connecting bar the central portion 7 of which is bowed upwardly so that it will clear the diflerentialhousing when the apparatus is beingused to remove or install a rear spring. The ends of this connecting bar terminate in squaredextensions 8. A pair of acks are denoted generally by the letters J and are herein shown as of the ratchet and lever type but the oper ating mechanism of these jacks is not of the essence-of the invention. V 1 For the purpose of'clearness, however, the housing portionof each jack has-been denoted by the numeral 9 while the movable portion is denoted by the numerallO. The movableportion 10moves in andout on the 'outer end ofthehousing while on the inner end of ets 11 so asto preventthe turning of the jacks in respect to the bar although this is not of the essence of'theinvention. -f 7 ,Theextremities of the movable: parts 10 are: beveled as is indicated at12'"so as to en'gagethe eyes 5 as clearly indicated in Figure 5." An anchor in the formlof a 11001: 14 with an eye extension 15passing about the fender of the bar 6 is adapted to have fulcrumed thereon the lever 16 to the intermediate portionof which are pivotally engaged as at 17 a pair of links. 18. These links18 are pivotally engaged as at 19 with the handles 2O oftthe'jack J. 1 r Obvi0usly, therefore, whenthe jacks are operated by the oscillation of the handle, 16, the movable parts 10 may; be-moved outwardly from eachother or inwardly" from each s other. for stretching the spring or allowing the Spring to contract.

Thus when the spring is detached from the wvith and the spring disengaged from the perch and then for operating the apparatus the spring may be allowed to slowly contract to its normal posi tion.

It is thought that the con:' ruction, operation, utility and advantages of this invention will w be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been disclosed in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. An apparatus of the class described comprising a pair of acks, a connecting bar between the jacks, a lever rockably engaged with the connecting bar, and means operatively connecting the lever with the jacks for simultaneous operation thereof, each jack comprising a stationary part engaged with the bar and a movable part having a beveled terminal, the inner ends of the stationary parts of the jack having formed thereon sockets, and the bar having extensions receivable in said sockets.

2. An apparatus of the class described comprising a bar having squared end portions, a rack and segment type ack having a horizontally movable element for engaging the eyes of the spring, and a stationary housing, carrying-an operating lever, and a socket for receiving one squared end portion of said bar, and another similar jack having a socket for receiving the other squared end portion of the bar; and a detachable jack operating structure comprising a pair of handles for engaging the operating lever of the jacks, the rods pivotally connected at its ends with said handles and arpintle secured to an intermediate portion of the bar and a lever pivoted at one end on said pintle and at its intermediate portion to said rod for simultaneously projecting or retracting said horizontally movable elements.

In testimony whereof I affix my signature.

HARRISON DRODDY.
