PISTON RING SETTER I Filed Jan. 23, 1929 w Pe'z/Zmzrzra/zmm TTTTTT EY Patented Dec. 24, 1929 PATENT OFFICE PAUL W. HEINRICH, OF GROSSE POINTE PARK, MICHIGAN PISTON-RING SETTER Application filed January 23,1929. Serial No. 334,573.
This invention relates to new and useful improvements in tools of the compressing type.
An object of the invention comprehends a multiplicity of pressure arms.
Another object of the invention contemplates shoes for the arms operable to compress work of diiferent shapes therebetween.
An additional object of the invention consists in the provision of a carriage for the arms.
A further object of the invention embodies an operating shaft mounted upon the carriage.
A major object of the invention comprises an expanding element operable in conjunction with the operating shaft to expand and contract the arms and shoes.
With the above and other objects in view, the invention further consists of the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.
In the drawing Figure 1 is an elevation of my invention.
Figure 2 is a top plan view thereof.
Figure 3 is a fragmentary longitudinal sectional view taken through the invention as applied and in use.
Referring to the drawing in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates a carriage or plate having a central opening 11 and tapped to accommodate a shaft 12 therein for adjusting movement rectilinearly therethrough. A cross bar or handle 13 is carried by and horizontally disposed upon the outermost end of the adjusting shaft 12 whereby the latter may be adjusted by hand.
Spaced ears 14, arranged in pairs upon the outer periphery of the plate or carriage 10 and radially disposed from the opening 11 therein, are adapted for pivotal connection with the uppermost ends of arms 15. Said arms terminate to provide, at their opposite ends, in inwardly and downwardly curved extremities 16, the purpose of which will be presently apparent.
An expanding and contracting element, in the nature of a disk, such as indicated at 20, is provided with a central opening to accomdate the reduced extension 21 provided upon that end of the adjusting shaft 12 between the arms 15. A nut or stop collar 22, carried upon the projecting portion of the extension 21 beyond the adjacent face of the disk 20, completes the swivel connection between the adjusting shaft and disk. Said disk is furthermore provided with elongated slots or openings 23 radially disposed therein in like manner to that of the spaces between the ears 14 of the carriage or plate 10 to accommodate the projecting portions of the arms 15 in the manner shown in Figures 2 and 3 of the drawing.
In the latter figure, the invention is shown applied upon an internal combustion engine piston to compress the packing rings therefor. It is obviously understood that the invention may be made in different sizes for use upon different types of pistons and having different numbers of piston rings to be compressed to facilitate proper insertion of the ring fitted piston within its respective cylinder. The shoes 17 are adapted to engage and overlie the split ends of the piston rings whereas the remaining portions thereof will engage and compress the adjacent portions of the companion piston rings at points remote from the split ends thereof. As the piston is shifted downwardly within its cylinder, the upper side of the cylinder block will engage the adjacent ends of the shoes 17 and the rings will be properly inserted within the cylinders uninjured and the process of insertion thereof will obviate the possibility of scoring the walls of the cylinder by the projecting split ends of the piston rings contacting therewith.
It is obviously apparent that the work engaging faces of the shoes 17 may be knurled, toothed, polished, or curved, pursuant to the particular employment of the invention.
The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.
Having thus described the invention, what is claimed is:
1. A tool comprising a plate having a centrally disposed and tapped opening, a shaft member exterior-1y threaded and adjustably mounted within the opening in said plate, arms carried by the plate, a disk having swivel connection with one end of the shaft, and said disk having portions removed to accommodate said arms to facilitate relative expansion and contraction of the free ends thereof.
2. A tool comprising a plate having a centrally disposed and tapped opening, a shaft member exteriorly threaded and adjustably mounted within the opening in said plate, arms carried by the plate, a disk having swivel connection with one end of the shaft, said disk having portions removed to accommodate said arms to facilitate relative expansion and contraction of the free ends thereof, and shoes carried upon the free ends of said arms.
3. A tool comprising a plate having a centrally disposed tapped opening, an adjusting shaft exteriorly threaded and adjustably mounted within said opening, a disk having swivel connection with one end of said shaft,
the disk having portions removed and radially disposed from the swivel connection, ears arranged in pairs upon said plate having the spaces therebetween radially aligned with the openings in said disk, arms pivotally connected Within the spaces between said ears and projected through the openings in said disk, the outermost extremities of said arms being downwardly and inwardly curved, and shoes having channels to accommodate and pivotally secure the aforementioned extremities of said arms for rocking movement thereon.
In testimony whereof I aflix my signature.
PAUL W. HEINRICH.
