WORKHOLDER.
.application filed November 23, 1921. Serial No. MKM?.
To all wwmiz't may concern: y
Be it known that we, JOHN P. Fncnnr and JOHN H. NnwI-rARD, citizens of the United States, and residents of Allentown, in the county of Lehigh and State or Pennsylvania, have invented a new and usetul 1mprovement in Workholders, of which the following is a specication.
Our invention relates to work holders and its all important object is to provide a work holder particularly adapted to holdy piston rings while filing the same for proper ritt-ing on the piston although not restricted to such use. i
A second important object of the invention is to provide a combination device which will hold the piston ring in a horizontal position for tiling the upper and lower surface thereof and after such operation will hold the piston ring in a vertical position while the ends thereorl are lapped or tiled.
It is another object of the invent-ion to provide a work holder which includes a pair of oppositely movable carriages and sets ot supplemental gripping members. one set ot', which being adapted Jfor use in holding annular bodies such -as piston rings and the other set being adapted for holding a rectangular body.
With the preceding and other objects and advantages in mind, the invention consists of the novel combination ofelements, constructions and arrangement of parts to be set forth in detail, claimed and illustrated in the accompanying drawings, wherein:
Figure 1 is a perspective of our improved work holder.
Figure 2 is a perspective of one of the movable carriages embodied in the invention. f
ldigure 3 is a transverse sectional view taken on line 2--2 of Fig. 1.
Figure 4 is a plan view of a modified embodiment of the invention, parts being broken away. Y
Figure 5 is a perspective of one of the gripping elements for use in holding an annular body.
Figure 6 is a similar view of one of the gripping members for holding a rectangular body, and
Figure 7 is an enlarged fragmentary plan view illustrating the device as used to hold.
\ arectangular object.
Referring to the drawing in detail.- where in corresponding characters of reference designate corresponding parts throughout the several views, the numeral 5 designates a cast metal rectangular base having a transverse nl`shaped groove or counter-sink 6 therein adjacent one end thereof. As shown in Fig. l the groove or countersinlr6 is closedf at one end thereof and constitutes a bearing section 7. Extending longitudi- G5 nally inthe groove or counter-sink 6 is a hand operated screw 8 having one-half ot.
its lengthprovided with right-hand threads 9 and the other halt of its length provided with left-hand threads 10. One end of this screw is journaled between the bearing sec tions 7 and the upper removable bearing section 11,` the latter being secured to the base 5 by fastenings 12.
Arranged in opposed relation and adapted tor longitudinal movement toward and away from each other in the groove 6 is a pair of T-shaped blocks or carriages 13. These blocks or carriages 13 are provided with horizontally threaded bores 14 through 80 which the threadedstem 8 passes. Each of the blocks or carriages 13 has formed with. at its upper end and at the rear edge there of, a rectangular extension 15 while the upper surface of these blocks or carriages are and longitudinally bowed resilient clamps 1T 90 to the outer tace of aflongitudinal centre oit which a Tshaped member 18 is secured shown in Fig. n5. The vertical legs 19 ot these 'lV-shaped members 18 are rectangular in cross section and are removably received in rectangular recesses 21, in the surfaces 16 of the blocks or carriages 13. With the legs 19 thus engaged the horizontal legs of the 'lV-shaped members will abut the vertical extensions 15 and thereby prevent the re 100 silient clamp 17 from becoming distorted should the blocks or carriages 13 be. moved too close together.l By the provision of these resilient clamps 17 it will be obvious that they will conform to various sized piston rings. In order to indicate when the surfaces of the piston ring T are level, a sury face plate 22 is provided in the base 5.
A vise 23 is carried by one end ot the base 5 and includes a pair of horizontal jaws 211 M0 which holds the piston ring in. a vertical position as shown in dotted lines in Fig. 1 so that the ends thereof may be liled or lapped. A hand operated screw 25 is associated with the vise 23 for moving thejaws into clamp ing engagement with the piston ring.
When it is desired to hold a rectangular object on the car'irages 13 shown in Fig. 7 rectangular jaws 26 having lugs 2T are arranged on the blocks or carriages i3 with the lugs engaged in the recesses 2l.
It is to be` understood that the form ot our invention herein shown and described is to be taken as a preferred example of the same and that various changes in the shape7 size and arrangement of parts may be resorted to without depart-ing from the spirit of the invention or the scope of the subjoined claims.
Having tliusvdescribed our invention what we claim as new and desire to secure and )rotect by Letters Patent of the United tates is:
l.v A work holder comprising a horizontal base upon which the work to be held rests and provided with a transverse groove, rarriages adjustable longitudinally in the groove, a common means for moving the carriages away and towards each other, and resilient longitudinally bowed gripping members carried by the carriages adapted to embrace an annular object.
2. A work holder comprising ay base having a longitudinal groove a pair of' rectaugular carriages movable in the groove, means for moving the carriages away and toward each other, each oi the carriages being provided with a recess in its upper face and an opposed longitudinally bowed resilient gripping element for each carriage and eacli including a member removably received in one of the recesses,
3. A device for holding fragile annular bodies including a base, a pair oi opposed resilient gripping elements mounted on tbe base, and means for moving the same in opposite directions.
1. A device for holding fragile annular bodies including a base upon which the article to be held is adapted to rest. a pair ol' longitudinally bowed resilient opposed gripping elements resting on the base, and means for adjusting the gripping elements in opposite directions.
A piston ring holder comprising abuse. a pair of longitudinally bowed resilient` grippiiig elements arranged on the base and adjustable in opposite directions. the gripping elements being of less vertical thick` ness than the piston ring held therebetween.
