No. 213,316 1 Claim. (Cl. 29259) The invention disclosed in the following specification and claim relates to a tool for use in the repair of automobiles. Specifically, the embodiment disclosed is a tool for compressing a portion of a starter of an automobile so that the starter may be disassembled and repaired.

Many tools for the compression of resilient members for repair purposes have heretofore been proposed. However, so far as I am aware, none of these prior proposed compressors are satisfactory in the compression of starter assemblies. This is mainly for the reason that the starter spring of many automobiles such as for example, the Ford, Mercury, and Lincoln automobiles, is enclosed in a rigid casing. Therefore it is diflicult to design a compressor which will contact and compress the resilient member so that holding pins, etc. may be removed to disassemble the various parts.

Objects One of the objects of my invention therefore is the provision of a new tool for the repair of automobiles.

A further object of my invention is the provision of a new compressor for starter assemblies for automobiles.

Further objects and features of my invention will be apparent from the following specification and claim when considered in connection with the accompanying drawings illustrating an embodiment of my invention.

In the drawings:

FIG. 1 is a view in perspective of a tool constructed in accordance with my invention;

FIG. 2 is a view in vertical section of the tool and of a starter assembly of an automobile to which the tool, similar to the tool shown in FIG. 1, has been applied for the purpose of compressing the assembly and disassembling the starter and the parts associated therewith, parts of the starter being broken away; and

FIG. 3 is a fragmentary view similar to FIG. 2 but having additional parts broken away and having the assembly shown in its compressed condition.

Detailed Description It may be seen that I have shown in FIG. 1 a compressor generally designated consisting of a U-shaped frame element or yoke 11, having a relatively heavy block 13 securely fastened at the base 12 of the U of the frame and having (at the ends of the legs of the U) retroversions 14 and 15. The base 12 of the U, as well as the block 13, are threaded for the reception of a threaded rod 16. The rod 16 is formed at its rear end with a handle 17 and adjacent to its forward end with a cross piece 18. The cross piece 18 is slotted as at 21 and 22 to embrace the legs of the U member 11, and has secured to it a cup member 23 formed with elongated cut-out portions 24 and 25.

As shown in FIG. 2, the starter assembly 31 includes a rigid casing 32 within which there is a resilient member 33 normally held partially compressed between the casing 32 and the plate 34. The starter assembly 31 also includes shafts 35 and 36. The shaft 35, adjacent its rearward end, is formed with a hole for a pin 37. Shaft 35 is also formed Patented Aug. 4., 1964 with a collar 38. When the assembly is in operation, the plate 34 bears against the collar 38. The rear end of the casing 32 bears on the pin 37. Thus the member 33 is held in partially compressed condition between the pin 37 and the collar 38.

Operation In the operation of my tool the screw 16 is rotated (in the direction opposite to the arrow) by the handle 17 so as to withdraw the cross piece 18 and the cup 23 toward the block 13. Thereupon the forward end of the tool may be slid over the frame 32. A slight pulling back of the tool 10 (i.e. to the left in the drawing) causes the retroverted portions 14 and 15 to contact the plate 34.

Thereupon the screw 16 is rotated in the direction of the arrow to move it forward in the yoke or U member 11, until the cup 23 contacts the frame 32. The cup 23 is positioned so that the ends of the pins are embraced by the elongated cut-out portions 24 and 25. The tool is now in the position shown in FIG. 2. Further rotation of the screw 16 by the handle 17 causes the retroverted portions 14 and 15 to move the plate 34 towards the rear of the frame 32 thus compressing the member 33. This releases the pin 37 from its clamped position bearing on the frame 32, and the pin 37 may be easily removed.

Rotating the screw in the opposite direction now re leases the frame 32 and it may be removed from its secured position on the shaft 35, and the member 33 also removed. The parts may now be completely disassembled and worn or broken parts replaced and the assembly repaired.

The assembling of the parts is of course the reverse of the operation just described. The new or repaired resilient member is put in place of the member 33 and the new casing 32, or repaired casing, if repair is necessary, is put in place of the casing 32. The tool is then applied in the same way as previously described and the member 33 is compressed. The pin 37 is re-inserted and the assembly is complete. The compressor is then released and removed from the assembly.

It is to be understood that the above described embodiment of my invention is for the purpose of illustration only and various changes may be made therein without departing from the spirit and scope of my invention.

I claim:

A tool for the assembly and disassembly of starter assemblies of automobiles wherein the starter assembly has a cup shaped casing, a resilient member in the casing, a plate also in the casing bearing on said resilient member, and a pin bearing on the rear of said cup shaped casing and holding the resilient member compressed against the plate comprising a U-shaped member having a forward end and a rear end; formed with a base at the rear end; having a threaded block secured within the base of the U- shaped member; having a pair of retrograded portions at the forward end of the U-shaped member;

a screw threaded through the threaded bore of the block member;

a handle for the screw;

a slotted cross member secured to the screw adjacent the forward end of the screw and formed with slots which embrace the legs of the U-shaped member;

a cup shaped member formed with a pair of semi circular cut-out portions secured to the screw adjacent to the forward end of the screw, the cup shaped member being provided for contacting the base of 'the frame of the starter assembly;

the retrograded end portions of the U-shaped member being provided for the purpose of contacting the plate on the starter assembly within the confines of 5 the casing of said assembly and for urging the plate of the starter assembly rearwardly to compress the resilient member of the starter assembly and the cut-out portions of the cup being provided for the purpose of embracing the pin which is to he removed. 10
