r001. FOR SEPARATING AND OILING srnmes.

To all whom it may concern:

residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Tools for Separating and Oiling Springs and I do declare the following to be a full, clear, and exact. description of-th invention, such as will enable others .skilled in the.art to which it appertains to make" and use the same, reference being had tothe accompanying drawings, and to the characters of reference marked-thereon, which form a part of this specification.

This invention relates to tools for separating and oiling leaf springs, and consists in theconstruction and arrangement of parts hereinafter fully set forth.

The object of the invention is the provision of a. tool which may be employed to first force the leaves of a composite leafspring, and more particularly of a vehicle leaf-spring, to a spaced relation, and which may then be employedto discharge a-suit= able lubricant between the leaves so spaced, thereby lubricating and'reducing friction be tween the contacting surfaces of the leaves and obviating the tendency of the springs to squeak when in action. This object is attained by the employment of the structure illustrated in the accompanying drawings,

. wherein":

Figure l is a view in side elevation of a handle between the'two positions respectively tool embodying my invention, showing in cross section a. leaf spring engaged'by said-i tool. and having two of its leaves spaced thereby. Fig. 2 isa longitudinal sectional view of the tool. Fig. 3 is a cross sectional view on line 3'.3 of Fig. 2. F ig. 4 is a plan view'of that end portion of thetool which is provided with jaws for engaging a spring.

Referring -now more particularly to the alined, are formed integral with theframe 1, a the bearing 2 andthe'member 4 being at opposite' ends of the frame and the bearing 3 being at an intermediate point. Between the .bearing '3 and member 4, .'the frame'is curved and off-set laterally toform a gooseneck, whereby a space is formed between i said parts 3 and 4, such as will allo'wtool Specification of Letters Patent.

Application filed April 2, 1915. Serial No. 18,663.

to be engaged with a vehicle spring 5, as shown in Fig. 1.

The bearings 2' and 3 are of different construction, the latter having a tubular open ing, while the former constitut-es'an arch, the opening of which, communicates with a housing 6 formed integral at the terminal of the body 1. In said bearings there is mounted to slide longitudinally a tubular member 7, which normally projects slightly beyondthe bearing .3'and considerably beyond .the bearing 2. Upon the latter projecting portion there is mounted fast agrip or handle 8, retained upon the member 7 by a screw-cap 9 engaged with the terminal'of said member.

Between the body of the tool and the member 7, a rackbar 10 is rigidly secured to said member, and is extended through the hearing 2, the sides of the rack having sliding contact with the bearing, thus preventing rotation of the member 7. Preferably, the rack will have its top face longitudinally grooved, whereby it may partially embracefthe memher 7, as is best shown in Fig. 3. The rigid housing6, and journaled upona pin 12, the ends of which are rigidly mounted in the side .-walls of said housing. Said pinion is integrally provided with ahandle for manually actuating its rotation. .To permit rotation of the pinion through displacement. ofits spring 5, relatively movable jaws 14 and 15 are respectively rigidly seated within the socket member 4 and the adjacent extremity of the member 7. The jaws are formed with chisel-shaped heads having cylindrical shanks, the latter being brazed or otherwise rigidly retained within the members 4 and 7, as is best shown in Fig.'2.- 1

It isprefer'red tofform shoulders 16 at the junctures of the heads ,and shanks of the jaws, which shoulders abut against the members 4 and 7 respectively to serve as limiting .stops. The head 15 is 'so proportioned as to offer no obstacle to withdrawal of the memher 7 from its bearings.

-. ,1h'e structure so far described forms a complete tool so far as regards its function of separating the leaves of a vehicle spring,-

and this operation will be explained before further describing the 7 construction. The operator will grasp the member 8 with one hand and with the other will manipulate the 1 to inject oil between the spring leaves will handle 13. Afterbringingthe tool to a position in which the jaws are just below the spring, it is raised upwardly to position a jaw upon each side of the spring, this being made possible by shifting the-handle to substantially the position shown in dashlines and thus spacing the jaws a distance greater than the transverse width of the spring. The handle 13 is now displaced toward the position illustrated in full lines, until the jaws are brought into contact with the spring at the intersection of two of its adjacent leaves. The handle 13 is now displaced to substantially the position shown in full lines, sufiicient force being exerted to wedge the jaws between said adjacent leaves, separating and providing a space 17 between the same into which a lubricant may be discharged. 's

#The features of the toolwhich adapt it now be described. An oil duct 18 extends 'a lubricant reservoir.

longitudinally and centrally through the shank of the jaw -15 and into the head thereof where it communicates with two divergent branch ducts 19 which open adjacent the intersection of. the sides and point of the .head. These ducts are to afford a discharge into the reservoir through the rear end. thereof by firstunscrewing the cap 9 andcompletely withdrawingthe. plunger head from the reservoir, or if'the lubricant be an oil, the jaw 15 may be immersed in the lubricant and the plunger-head displaced 'rearwardly to draw in the lubricant through the ducts 18 and 19.

It will be seen from. the foregoing description that a tool of this construction serves both to space the component membe 's ofia leaf-spring and to discharge lubricant between said members when spaced.-

It is to be noted that theparts of this "capped end of the tubular member.

tool will preferably be so proportioned that when passed between the spokes of a vehicle wheel to lubricate the springs of the vehicle, the handle members 8 and 13 will be outside of the wheel and the latter may be rocked without the wheel interfering.

The invention is presented as including all such changes and modifications as properly come within the scope of the following claims;

Having thusfully set forth my invention, what I- claim as new, and desire to secure by Letters Patent, is:

1. A tool comprising-a frame having a pair of slide-bearings, one of which is arghed and the other formed with. a tubular opening, an elongated member slidable in said bearings, arack longitudinally mounted "upon said member extending through the arched-member and engaging the same to prevent rotation of said elongated member,

' a pinion engaging said rack mounted upon said frame, means for rocklng said pmlon to actuate sliding motion of the elongated -member, and a pair of co6perating jaws respectively carried by the sliding member and by the frame, one of said jaws being tapered.

2.A tool comprising a frame, having a slide bearing, a non-rotatable sliding mem-' ber received by said bearing, a rack mounted upon the sliding member, a mutilated pinion normally engaging said rack and rotatable to. a position clearing the same, means for rocking said pinion to actuate the sliding member, .and apair of cooperating jaws respective'ly carried by said sliding member and by the frame, one of said jaws being tapered.

31A tool for separating and oiling the leavesof springs, comprising a frame, a,

tubular member slidably mounted upon said frame, forming a reservoir for lubricant, means for manually actuating the sliding "member, a pair of cooperating jaws, respectively carried-by the frame and by one end -of said tubular member, the other end her f arrediene 9? said jaws being tapered fa nd having' a passage communicating with said tubular member, a plungerhead reciprocatory within the tubular mem- 'ber,'and a rod rigidly connected with said plunger-head and projecting through the In testimonywhereof, I sign this specification in the presence of two Witnesses.
