TOOL FOR HOLDING PISTON RINGS IN THEIR SEATS.
Appneation mea october e, 1921. serial No. 505,876.
flo all whom it may concer/n.:
Be it known that I, VICTOR A. NnLsoN, a citizenlof the United States, and a resident'of the city of Portland, county of lil'ultnomah, and State of Oregon, have invented a certain new and useful Improvement in Tools for Holding Piston Rings in Iheir Seats, of which the following is a specification.
My invention relates to tools used. to contract piston rings and hold themv in their seats during the operation of inserting the assembled piston in the cylinder.
rlhe way these rings were commonly held in place was to encircle them with a band, the ends of which were held by a tool so that the band could be drawn tightly around the piston rings.
The tools commonly used for said operation required the handle to be held in a plane at right angles to the piston thus rendering the operation frequently very awkward.
The objectof my invention is to provide a tool using the ordinary type of pliers and so arranged that in operating therewith the handle will be held parallel with the axis of the piston, in this way rendering the operation more convenient as is self evident in Figs. l and 2 of the accompanying drawings.
A further object of my invention is to provide means for holding the ends of the bands used for compressing the piston rings in their seats, adapted to be incorporated in or to be applied with an attachment to ordinary pliers or a combination tool of the character illustrated in the accompanying drawings.
A still further object of my invention is to make my tool a simple and inexpensive device.
I attain my object in the device illustrated in the accompanying drawings, in which:
Fig. l shows a side elevation of my tool and illustrates its use in practice for drawing a band firmly about the piston rings in the operation of pushing them into their seats so the piston may be inserted in the cylinder;
Fig. 2 shows a front elevation of my tool as applied to the same operation;
Fig. 3 isa section on the line 3 3 of Fig. l; this view, in order to distinguish the band used for compressing the piston rings into their seats from the latter the band is shown as not yet drawn tight around the piston rings;
Fig. a is a sectional detail of the jaws of i the pliers with the clamping lips whichV held in place by screws e.' The lips f can be made integral with the pliers c or can be made separate as indicated in Fig. 5.
The utility of the invention is apparent from Fig. l. With the axis of the pliers parallel to the axisu of the pistonv and the cylinder it can readily be seen that a manY can work more readily than if the pliers were at right angles to the axes of the piston and the cylinder.
`This principle is veryl important because in most designs of internal combustion engines and plunger pattern pumps very little space is left in which to work. The common form of tool is impractical for this one reason in many cases.
While I have described my invention as v relating to compressing piston rings I wish it to be understood that this combination tool can be used for many other purposes without departing from the spirit of my invention.
In my'invention I can slip the contracting band in place over the first ring and -letthe handles extend up through the opening for the cylinder head'or out through the crank case, from which ever end the piston is inserted. Then by placing the handles of the pliers tight against the body of the can work with less than an inch of play.
The size of the slot d in the jaws of the pliers a is so designed that Vit will only allow a contracting ring of the proper thickness to be used. The clamping lip f is com-V pressed toward the body of the jaw g by the screw c. In Fig. 5 this screw e performs a double function; it not only holds the removable clamping lip f in place, but also piston compresses the clamping lip f so that it can secure a lirni grip on the band o.
My object of 'making the lip fseparate is so thatv it can be made of an elastic material and therefore not so easily broken.
A means 7av is also provided to be placed on the handles of the pliers so that they can be held in compression and so Vallow the workman the use of both his hands to do other work. This is very important because most or' the work will be done through the -fcranlrf case end and! therefore will not permit the useoty two hands.
I claim:
l. rThe combination in a tool of the character described, of jaws each provided with aliolding-lip on its exterior face at its tip,
the opposed faces of the holding-lip and the jaw being spaced to provide a slot between them for the insertion et a supplemental tool element, said holding-lip beingadapted tol be compressed against the underlying sui'- the lip against the underlying surface of the aw.
3. The combination in a' tool of the character described, of jaws each provided with a holding-lip on its exterior face at its tip, the opposed faces of the holding-lip and the jaw being spaced to provide a slot between them for the insertion of a supplemental tool element, a screw threaded through the lipv into the jaw -nearthe closed end of the slot. v
4. The combination in av tool of the character desc ibed, or jaw s, each provided with a recess in its exterior face at the tip, a holding-lip, seated in the'recess of each jaw,
having its face spaced from the opposed;
faces of the latter to provide a slot between them tor the Vinsertion of a supplemental tool, and a screw threaded through the lip into the jaw. y
The'combination in' a tool of the charlacter described, of jaws,each provided with a recess in its exterior face at the tip, a holding-lip, seated in the recess of each jaw, having its tace spaced Jfrom the opposed faces of the latterto provide a slot between them for the insertion of a supplemental tool, a screw threaded through the lip into the jaw, said lip being adapted to be conic pressed against the underlying jaw surface by said screw and means applied to the handle end of the tool for securing the jaws in compression.
