UNITED STATES FRANK DANIELSON,v OF CHICAGO, ILLINOIS.

VISIE.

Application led August 23, 1920. Serial No. 405,275.

T all w hom it may concern Be it known that I, FRANK DANrELsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Vises', of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming `a part of this specification. v

This invention relates to vises and more particularly `to a vise that is adapted for securely holding various automobile parts without any damage thereto, such for example as pistons,cam shaft bearings, bearing caps, reverse gears, etc;

It is a purpose of the invention to provide a vise that is particularly adapted for holding Ford cam shaft bearings so that the same will not be bent out of shape while reaming the same. It is'also a'purpose of the invention to provide suitable means for holdingbearing caps tightly in position in said vise.

It is a further purpose of the inventionto provide suitable means on a vise of this character to prevent a reverse gear from turning in said vise, said meanscomprising a suitable lug or pin on the rear of said vise adapted to engage certain portions of said reverse gear to hold the same, said lug or pin being movable into and out of operative position. V

It is a further purpose of theinvention to providey a suitable guide for filing valve stems in said vise. To accomplish this purpose the vise is provided with an operating cam having Va hollow hardened pivotV pin serving as a guide for this purpose. It is suitable means for clamping the valve in position .in said hollow pin for tiling.

Other objects and advantages vof the invention will appear as Athe description of also an object of the invention to provide.

.FigL 5 is a vertical ysectionalviewof a portion of the viseshowing the same arranged for holding a bearing cap; Y

Fig. 6 is a section taken on line G-G'of Fig. y5; and Y" n Fig. 7 is a vertical sectional view of a Vportion ofthe vise showing the same vas holding a reverse gear, andshowing means for holding the reverse gear from turning in operative position. f Referring 'in detail to the drawings'the improved.` vise is mountedv on any suitable table or base lmember 10, and comprises 'a vbase portion 11 which has formed integral therewith axed jaw member 12, which jaw member is yprovided with .fa .substantially semi circular inner face 13|. Slidably mounted on the base 11 is afjaw'meniber 14,

said `jaw member 14 also being provided with a curved inner face 15 that is substantially semi-circular. Thel ja .w`rnember .12 has outwardly extending end portionsfl' .in which are secured in any suitable, manner the guide pins 17v and the jaw 4member 14 Ais y provided with extensionsA 18 e which are adapted toslidably receive the pins 17, which pins act as guides for the .jaw-member 14 as it member 19 provided with a flattened portion 19 is pivotally mounted on the upper is movedl backward andforwardg `on the .upper` face of the base 11. A .cam

'withy a handle 20for operating. thewsame. ,l

It will be Iclear that when the cam 19 is lin the position shown in Fig. 2 ,the jaws l12 and 14 `will be forced toward each other to hold a member, such as thejpiston 21 shown in Fig. 1, therebetween... i

In order .to make it possible to use thevise for v.various size pistons, lining membersor v collars 22 are-providedthat tit onthe interior` of the jaws and areof such inner curvature as to properly fit the outer curved surface of the piston 21. The collar comprising the member 22 is provided with an inner facing of any suitable soft material, such as felt fibre or leather, to prevent `marring of the piston.` l

vin place.

In order to provide for the return of the jaws to an open position when the lever is moved to a position at right angles to that shown in Fig. 2, coil springs' 23 are provided on each of the pins 17, which coil springs may directly engage the projecting portions 16 and 18 on their opposed flat faces or plates, such as the plates 24 shown in Fig 2,

may be mounted between the ends of thel coil springs and the flat faces of the portions 16 and 18. The plates 24 extend inwardly beyond the curved surfaces of the jaws 12 and 114 and engage the end portions of the members 22 so as to hold the same in engagement with the jaws 12 and 14. The pivot pin for the cam member 19 is made with a central bore 25 adapted to receive the stem y'26 of a valve 27 and is hardened for a purpose that will be presently eX- plained.v The lower end portion of the'bore 25 is provided with a'iiared mouth 25 so that the stem 26 may be .more readily inserted therein. The upper end portion of the pivot pin 28 is provided with a flange 29 which bears on the upper surfaces of the cam 19 'and the lower end of the pin extends through the enlargement30 formed onthe forward end of the basevll. The enlargement 30 is also provided with a suitable screw threaded opening to receive the set screw 31, which is provided with a suitable handle 32.for turning the same, and the pivot pin 28 is provided with an opening in alignment with the set screw 31. They set screw 31 serves the purpose of preventing the pin 28 from turning in the base 11 and also holds the pin 28 The set screw 31 also serves the purpose of hol-ding the valve stem 26 in any desired position within the hollow pin 28. The purpose of providing the hollow pin is to provide a guide for filing the endof the Avalve stein 26 oft' square' as 'the pin 28 and flange 29 are hardened. All that is necessary in order to file off the end of the valve stemis to set the pin 28 in the desired position with the set screw 31 and then le off the projecting portion thereof untilv the same is flush with the upper surface of the iange'29, after which `it will be impossible to file further as the'flange 29 ishardened. The rear portion of the vise is provided with Va boss or projection-33, which is provided with a horizontal :bore 34 and a vertical bore 35. Iithin the llatter bore is I mounted to slide vertically apin 36 provided with a pairof circumferential grooves v37 and 38, and mounted within the horizontal bore 34 is a coil spring 39 Aand a ball bearing 40, the ball being adapted to be pressed into either the grooves 37 or 38 by thepressure of the spring 39A thereagainst. It is, of course, un-

rdei-stood that the opening 34 is closed at 'the outer end by means of a suitable plug 41. The strength of the spring 39 is such that the pin will be held in either the vposiposition shown in Fig. 7 to that shown in Fig. 1. The pin 36 is used as shown in Fig. 7 in which there is shown a reverse gear 42 suitably mounted between the jaws 14 and .12, a split ring 43 being interposed between the jaws of the vise and the pinion 44 on the reverse Vgear to hold the same firmly `within the jaws of the vise. If nothing were provided to lprevent vthe reverse gear from turning in the vise, the reverse gear would turn in the collar or split ring 44 when operated on by a reamer or similar tool.

In order to prevent the turn-ing thereof the pin 36 is raisedto the position shown in Fig. 7, when the pin will engage'in one ofv v sure on the pin 36 it can be forced from the i the openings 45 between the spokes formed in the web portions 46of the member 47 of the reverse .,gear, thus rholding the same from turning. 4lVhen the vise is used for other purposes, thepin36 is moved to the v positions shown in Figs. 1 and 3.

In Figs. 3 and 4 the vise is shown clamping a cam shaft bearing` 48such as is used in a rFord automobile.v The cam shaft bearing 48 is made in onel piece as willbe clear from Fig. 4, andis provided with V-shaped grooves 49 that extend nearly entirely through the material of thebearing at diametrically opposite points. It will be evident that if such a bearing as that shown were placed in an ordinary vise the same would be very easily bent out of shape due to the weakened portions at 49. The purpose for providing the weakenedportions at 49 is to make it possible to separate the twoha'lves of the'bearings as'they would .be when put is usually necessary to reain out the inside of the bearings before putting the same 1n place, as these are made a trifle .small inthe factory. ,y i

In orderto do this reaming it isnecessary to provide means for clamping `thebearing without distorting the same. i 4

, In Figs. '3 and 4 the bearing 48 is shown as being provided with suitable meansfor holding the same, and in Fig. 3 the leamer 50 is shown in position therein. The holding means forv the bearing comprises a collar made up'of the two portions 51k and 52,

yin use by a blow ofv a hammer. However, it

which collar is providedwith a bore in the upper portion thereof large enough lto. re-l ceive the bea-ring 48, and at the lowerend thereof with a smaller bore 53 large enough for the reamer 50 to passtherethrough and a ledge 54 is provided upon 'which the bearing 48 is adapted to rest. The lower end por tion 55 ofthe collar is made small enough to pass through the opening 56 in the face so that the offset portion 57 may rest suitably upon the upper surface of the base member' l1. The upper portion of the collar 5l is provided with afcircumferential groove 58 within which the split ring 59 is adapted to lie. The ring 59 is made 'of resilient material, and is adapted toLold the members 52 and 5l in assembled relation, but permits the same to be spread enough to receive the bearing 48. The collar comprising the members 5l and 52'is suitably mounted between the jaws of the vise and suitable bushings or lining members 22 are interposed be? tween the jaws 14 and 12 and the members 5l and 52 so that the same will properly fit within the jaws of the vise.

In Figs. 5 and 6 the vise is shown as being used for holdingthe bearing cap 60 inposition while filing the same, the file being shown at 61. The devices for holding the bearing cap 60 comprise apair of members 62 and 63 which together forma block having a circular outer face adapted to fit withn in the bushing or ring portions 22, which have an external curvature fitting that-of the external curvature of the' jaws l0 and 14. The members 62 and 63 are the halves of a block which together form a vcentral recess 64 which is adapted to receive the upwardly curved portions 65 ofthe bearing cap 60, the recess '64 being provided with laterally extending'portions 66. "The block portions 62 and 63 are each provided with a vertical bore vadapted to receive one of the legs- 6T of the U-shapedresilienty member 68, the resilient member being adapted to hold the two halves of the block in assembled rela# tion, and the eXtreme end portions 69 thereof extend upwardly beyond the upper flat faces of the blocks62 and 63 'tobe received within the bolt openings 70 in the bearing cap 60 to hold the same firmly in position upon the blocks 62 and 63 while filing the same as shown in F ig. 5. As the members 62 and 63 forming the block are securely clamped within the vise, and as the portions 69 holdy the member 60 firmly in position, and as the 2. vise of the character desc-ribed`com-- prising a base, a pair ofjaws on said jbase, one of said jaws being movable relativelyftov` said base, ay pivot pin provided with a longi tudinal bore mounted on said base, and a cam for moving said j awmounted 4on said' pivot pin,`said pivot pin being adapted to receive a valve stem therein andhaving a hardened top surface wherebv the same serves as a guide for filing the same.
