TOOLS FOR MOUNTING FUEL PUMPS ON ENGINES Filed May 26. 1964 INVENTOR.
z 'vewfz if Wewmam BY w a fhiw y United States Patent 3,222,024 TOOLS FOR MOUNTING FUEL PUMPS 0N ENGINES Everett H. Newman, Duncan, Okla, assignor of one-half to M. J. smothers, Amarillo, Tex. Filed May 26,1964, Ser. No. 370,237 4 Claims. (Cl. 248316) This invention relates to tools for mounting fuel pumps on engines, and more particularly to tools for holding the push rods of modern Chevrolet V-8 engines up out of the way while loosely fitting the fuel pumps on to the engine blocks in preparation for mounting them.
Modern Chevrolet V-8 engines have fuel pumps located on the lower right hand side of their blocks. Each fuel pump has a lever which projects into an opening in block. A cam driven push rod works the lever back and forth so that it actuates a diaphragm in the pump.
The push rod is free-floating, i.e., it is not secured to anything. The result is that when a fuel pump is removed from the block, the push rod falls down and has to be lifted up, and held up, before the pump can again be installed or replaced, in order for the lever to be placed beneath it.
Because of the location of the fuel pump on the block, it is very difficult to install a new fuel pump on the block of a Chevrolet V-8 engine without tearing down the whole assembly of hoses and other parts, especially if the engine is equipped with air conditioning apparatus.
It is an object of the present invention to provide a simple tool for raising and holding up the push rod of such an engine as that described until the fuel pump is loosely fitted on the block, after which it can be readily removed and the mounting of the fuel pump completed.
Other objects and advantages will become apparent from the following description of two embodiments of the invention, when taken in connection with the accompanying drawing in which:
FIG. 1 is a fragmetary view of the front end of a Chevrolet V-8 engine with the fuel pump thereof loosely fitted thereon and with a tool constituting one form of the invention applied thereto and holding the push rod thereof up out of the way while the pump is being installed;
FIG. 2 is a side view of the tool shown in FIG. 1;
FIG. 3 is a side view of a second form of the invention and showing a segment of a Chevrolet V-8 engine of a different design than that of FIG. 1; and
FIG. 4 is a front view of the tool of FIG. 3.
Referring to the drawing in detail, it will be seen that FIG. 1 shows a portion of a Chevrolet engine block at 10, with a fuel pump 11 loosely positioned thereon. One of the bolts which clamps the pump 11 to block is designated 12. Shown extending diagonally, in dotted lines, is the push rod 13, which is reciprocated by a cam (not shown) in the engine to engage a lever 14 which actuates the diaphragm of the pump 11.
In accordance with one embodiment of the present invention, a tool for holding the push rod 13 up while the pump 11 is loosely fitted in position is shown in FIGS. 1 and 2 as consisting of a permanent magnet 15 mounted on a small frame or arm 16 by a clamp 17.
The lower end of the frame 16 has a hole in which is fitted a shank 18, which is threaded and provided with a thumb nut 20.
As viewed in FIG. 2, the left hand side of the shank 18 supports a blade 21 of resilient material, so that it can pivot to the right or left but not move lengthwise on the shank or rotate upon it. Thus the shank 18 may be provided with a slit into which the top of the blade 21 extends and be secured by a pin 22.
In the embodiment of the invention shown in FIGS. 1
and 2, the blade 21 may be a straight, flat rectangular piece of spring steel. A clip 23 of spring wire is clamped securely to the blade 21. The clip 23 has portions which are semi-circular in shape and so spaced as to frictionally engage the push rod 13.
Since the blade 21 may be made of spring steel, it is within the scope of the invention to have the clip 23 integral with the blade 21 and stamped out of the same stock, but this detail has not been illustrated, as it is obvious to those skilled in the art that various changes may be made in the structure without departing from the spirit of the invention.
The operation of the tool shown in FIGS. 1 and 2 is as follows:
When a defective fuel pump is removed from the engine block 10, the push rod 13, which is freely floating in the block, falls down as soon as the lever 14 no longer supports it. Until the push rod is then raised up out of the way, it is impossible to mount a new or repaired fuel pump '11 on the block. Due to the location of the pump, it is very difiicult to hold the rod 13 up while inserting the lever 14 beneath it. Usually the mechanic has to perform this operation with only one hand.
In accordance with the present invention, before attempting to place the lever 14 beneath the push rod 13, the tool is applied to the block by placing the magnet 15 against the forward wall of the block 10. The position is adjusted until the shank 18 occupies approximately the position shown in FIG. 1 in front of and above the opening in the block 10.
When in proper position, the blade 21 extends into the opening in the engine block 10. The clip 23 is then snapped on to the rod 13 and the clip and rod are then raised up until the rod 13 is out of the way of the lever 14. The parts of the tool may then be adjusted, with or without loosening and then tightening the thumb-nut 20, the magnet 15 permitting movement but holding the shank 18 in its adjusted position.
With the rod 13 properly held up out of the way, the pump 11 may then be easily placed in the position shown in FIG. 1 and the bolts 12 started into their sockets in the block 10. When this has been accomplished, the tool can be removed from the rod 13, and from the block, by the simple operation of pulling it away. The clip 23 being yielda'ble, and the blade 21 being flexible to some extent, no problem arises as to interference with parts of the pump 11 or the block 10.
The tool shown in FIGS. 1 and 2 is particularly designed for use on Chevrolet V-8 engines having 265, 283 and 327 cu. in. cylinder displacements, respectively.
On larger Chevrolet V-8 engines having 348 and 409 cu. in. cylinder displacements, a tool different than that shown in FIGS. 1 and 2 may be employed, and such a tool is shown in FIGS. 3 and 4.
The larger Chevrolet V-8 engines mentioned have a bolt on the front part of the block near the right hand side thereof, which is used to connect a ground wire for the battery to the block. Such a bolt is shown in FIG. 2 of the drawing at 25 and a small segment of such an engine block is shown at 26.
The tool of the present invention designed for use with the larger Chevrolet V-8 engines does not employ a mag net to hold it in place, but the small frame 27 is provided with a forked portion 28 at its upper end to be secured to the block 26 by the bolt 25.
The frame 27 is of a particular shape to accommodate the movement required as will be explained hereinafter. It is provided with a reverse bend when viewed transversely, as shown in FIG. 3, and it is provided with a lateral offset when viewed from the front, as illustrated in FIG. 4.
There is a cylindrical rod or shank 29 pivoted upon the lower end of the frame 27. The pivot is such that the shank 29 cannot be extended more than 90 from the vertical part of the frame, as illustrated in FIG. 3.
At the opposite end from the frame 27, the shank 29 is connected to a blade 30. The blade 30 is capable of swinging to the right or left on the shank 30, as illustrated in FIG. 3, and the construction may be the same as described above in connection with the embodiment of the invention shown in FIGS. 1 and 2.
The blade 30 may be made of the same material and be used similarly to the blade 21. It should be noted, however, that the blade 30 is not the same shape as the blade 21. It has a bend in it, as shown in FIG. 4, whereas the blade 21 has no bend.
The operation of the tool shown in FIGS. 3 and 4 is similar to that of FIGS. 1 and 2 insofar as raising and supporting the push rod 13 until the lever 14 is in place, and a description of this need not be repeated here. The removal of the tool from the block after the pump is loosely mounted on the block is different, however.
On the larger Chevrolet V-8 engines, there are hoses and other obstructions in front of the block, and the tool of FIGS, 3 and 4 is designed to overcome the, difficulties these incur.
To remove the tool from the block 26, the bolt 25 is loos ned and the frame 27 pulled down until the forked portion 28 is beneath the bolt 25. With the parts swung to the right of the block slightly, and with the shank still remaining in substantially a horizontal position and the clip of the blade 30 still engaging the push rod, the frame 27 may then be folded down along the shank 29 until it, too, is in nearly a horizontal position. The tool can then be pulled away from the push rod and the installation of the pump completed.
While only two embodiments of the invention have been shown and described herein, it is obviousthat various changes may be made in the arrangement and construction of parts without departing from the spirit of the invention or the scope of the annexed claims.
I claim:
1. In an automobile engine of the V-8 type of the class wherein a fuel pump is mounted adjacent an opening in the block and is actuated by a push rod which is freefloating in the block near the opening, the combination with a push rod of a tool consisting of an arm having means for attaching the arm to the front end of the block, a shank attached to the arm and extending to the side of the block above the opening therein, a single blade of resilient material pivotally mounted on the shank and extending into the opening in the block, and a spring clip on the lower end of the blade frictionally and yieldably grasping the push rod in the block.
