PISTON RING COMPRESSOR Filed Feb. 10, 1926 Inventor Attorney 1,605,990 H. c. SEGELKEN Nov. 9, 1926.

t eatise HERBERT G. SEGELKEN, 0F PHOEINTICIA, NEW YORK.

PISTON-BING- COMIPBESSOR.

Application filed February This invention relates to piston-ring compress'ors, and has for its primary object to provide such a compressor that may be applied to a particular ring within a groove of the piston and then released for permitting both hands of the mechanic to properly force the piston into the engine cylinders, the compressor automatically maintaining the ring in compressed condition after the same has been once applied.

A further object resides in the provision of such a compressor that may be easily applied to piston rings of various sizes and that may be used for the purpose intended without requiring any unusual skill upon the part of the mechanic.

A. still further object is the provision of a compressor of the type mentioned that is relatively simple in construction and inexpensive of manufacture, the invention comprising but few parts and these so correlated as to reduce the possibility of the disarrangeinent to a minimum.

With the foregoing and other objects in view as the nature of the invention will be better understood, the same comprises the novel form, combination, and arrangement of parts hereinafter more fully described, shown in the accompanying drawing, and claimed.

In the drawing wherein like reference characters indicate corresponding parts throughout both of the views:

1 is a longitudinal section of a piston-ring compressor constructed in accordance with the present invention, and

Fig. 2 is a side elevation thereof.

Now having particular reference to the drawing, my novel piston ring compressor includes a cylindrical handle member 5 of wood or other substantial but inexpensive material open at one end and provided at its opposite closed end with a slot 6, the end walls of which are beveled as clearly shown in Fig. 1. The compressor further includes a relatively wide split spring steel ring 7 upon the ends of which are formed arms 8 of spring steel that converge inwardly toward each other as clearly shown in Fig. 1, the same adapted to enter the slot 6 of the cylindrical handle 5, and from the ends of which arms extend relatively elongated horizontal bars 9 movable within the cylinder 5, the outer ends thereof extending outwardly of the cylinder and being so bent as to provide outwardly extending finger Serial No. 87,328.

pieces 10 teat will engage the adjacent end of the cylinder for pi. venting the withdrawal of the bars therefrom. V

Surrounding said bars 9 between the tinger pieces 10 and the forward end of the cylinder 5 is an expans ble coil spring 11 that normally serves to draw the fingers 8 into the cylinder for consequently compressing the band 7, it being obvious that by forcing the bars 9 upwardly or outwardly of the cylinder through the medium of the finpieces 10 the band 7 will by reason of the material forming the same expand for permitting a piston ring A. to be disposed therein.

It will be obvious that after the band 7 has been applied to a piston ring within a piston groove and then released, the spring 11 will automatically draw the bars 9 clownwardly within the cylinder, which action will move the arms 8 toward each other, consequently compressing the band upon the ring and in turn compressing the ring within the groove and flush with the piston wall for permitting the piston to be moved down wardly within the engine cylinder, the positioning of the piston within the cylinder being performed by both hands of the mechanic by reason of the fact that the com pressor will be automatically maintained in proper position.

Minor changes may be made in the invention without departing from the spirit and scope of the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. In a compressor for piston rings, a cylindrical handle member, a split spring steel band, rods upon the ends of the band slidable within said handle member, cooper ating construction between the rods and said handle member for normally moving the band toward the handle and simultaneously compressing said band, and means at the opposite end of the handle whereby the band may be moved away from the handle and into expanded condition.

2. In a compressor for piston rings, a normally expanded split steel band, a cylindrical handle member, rods extending from the ends of the band and entering said handle member, cooperating construction between the rods and said handle member for drawing the rods through the handle member and Simultaneously compressing iii-ii the band, and means at the opposite end of the rods externally of the handle Whereby the same may be moved in a reverse direction to permit of the expansion of said band.

3. In a compressor for piston rings, a normally expanded split steel band, a cylindrical handle member, rods extending from the ends of the band through said handle,

the free ends of said rods being disposed laterally in opposite directions to provide finger pieces for drawing' the rods through the handle member and simultaneously cor pressing the band, and an expansible coil spring arranged Within the handle and encircling said rods.

In testimony whereof I aiiix my signature.
