VALV E-LIFTEB.

To all lwlw/m, t may concern.'

Be it known that I, LEWIS H. HoLcoMB, a citizen of the United States of America, residing at Columbus, in the county of Franklin and State of Ohio, have mvented certain new and. useful Improvements 1n Valve-Lifters, of whichA the following is a specification.

The presentinvention relates to lmprovements in valve lifters for use in connection with internal combustion engines for the purpose of lifting the valves from their seats in order to gain access to certain parts of the engine, for replacing valves, etc without the necessity of long, tedious work and resort to laborious proceedings and handllng of the cylinder or motor as is frequently the case.

The primary object of the invention is the provision 0f a tool that may be handled with facility, by one person, that is'compact and durable, efficient, and capable of v adjustment so that it may be used in places,

ordinarily diiiicult of access, with facility.

The invention consists incertain novel combination and arrangements of parts as will be fully -described and claimed and as illustrated in the accompanying drawings. I have depicted one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of my invention, and

- while I have illustrated and shall describe the device as a valve lifter, it will of course be understood that I shall avail myself of all the usesto which the implement may be subjected, and that the device may be altered within the scope of my claims.

Figure 1 is a side elevation of a device made according to my invention. Fig. 2 is a top plan view of the device of Fig. 1, showing in dotted lines the capability of adjustment of the device. Fig. 3 is a plan view of 'a different sized jaw by which the implement may be adapted for use with different sized valve stems etc. Fig. 4 is an edge view of the jaw of Fig. 3, showing in dotted lines the xed jaw of the tool. Fig. 5 illustrates the use of the implement (shown in dotted lines) as applied to an exhaust valve of an internal combustion engine, the spring of the valve being shown as compressed. K i

In the preferred embodiment of the invention as illustrated inthe drawings I Specification of Letters Patent.

Application filed April 22, 1915. Serial N0. 23,058.

have shown two vparallel jaws l1 .and 2, the former a movable or slidab-le one and the latter stationary, or fixed with relation to the jaw 1. The movable jaw is slidable on the post 3 which is rigid with and `lixed to the jaw 2, and the post is grooved at.4 for accommodation of the feather 5 carried by the sleeve 6 of the jaw 1. In this manner the jaw 1 through the 6 is movable or slidable on the post, but lateral movementdof -the jaw with relation to the post is prevented bythe engagement of the feather of the jaw inthe groove of the post. By this arrange-- ment and combination of parts it will be seenthat the movable jaw is capable of a direct and straight motion with relation to the Xed jaw so that, when compressing the valve spring 7 the spring is moved in a dis rectline and is held against deviation. This is a most desirable feature of the invention as it prevents the accidental displacement of-the spring when the latter is unsupported.

The jaw l is moved through the medium of a pair of

lever handles

8 and 9, the former pivoted at 10 in a fulcrum link 11 and pivotally connected at 12 to a bolt 13 swiveled in a bracket arm 14' integral with and projected from the sleeve of the movable jaw.

The two handles or

levers

8 and 9 are made preferably from stamped metal, the sections of each handle being joined together by rivets as 15 while the operating ends of the handles are forked or spread apart to accommodate the link 11 and their swivel bolts. The link 11 as clearly seen is a metallic strip fashioned with a series of fulcrum holes 16 to receive the pivot pin 10, and-at 17 the link is pivoted in the lever handle 9i The lever handle 9 is in turn pivoted at 18A to the bolt 19 which is swiveled in the bracket arm 20 directly in line with and beneath the swivel bolt 13 of the lever 8. A lug 21 is provided on the handle 9 t0 retain the handle 8 when the jaws are held open. Both the jaws have mouths or cut away portions as 22, and in Fig. 2 the mouth or cut away portion is of a size to span or fit around a large size valve stem 23, but to adapt the implement to smaller size stem, I employ detachable supplemental jaws 24 as illustrated in Figs. 3 and 4. The mouth 25 of such a and the supplemental jaw is formed with jaw is made of smaller dimensions',

'2 i,w'hnaaaYA l valve stems; and they held by the

bolt

2,8 passed through the o'penside flanges v26 and lcentral. lugs 27 so that the supplemental jaw mayv be slipped over lthe jaws 1 or 2 and secured by a set bolt 28 tothe first jaw. A In this manner the jaws are adapted tothe variable diameters of may be detachablyv ing 29 in the jaw 24.

In Fig. 2 the. radius-of movement ofthe jaws upon their "swiveled supportsis indicated by the dotted circular line, and it will be seen that the jaws may be bodily and synchronously turnediupon their swivel supports throughout a wide radius Lthus enabling the device to be used with facility in other wise inaccessible and difficult places.

By means of the series of openings 16-in the link 11 the fulcrum point of the lever 8 may be altered "and the movement of 'the slidable jaw with relation to the xedjaw may be adjusted to adapt the device for use with diierent sized valve accessories.

In usn the device, the two jaws are in closed position, in contact, with the two handles spread apart. The fulcrum bolt 10 of course has been properly adjusted to the required height, and the swiveled jaws have been swung around to the proper angle in order to get at the valve stem and spring in proper position. The lever handles are now brought 1together bv swinging the handle 8 on its pivot or fulcrum bolt 10 and this action raises the movable jaw 1 so that it slides A upwardly on its post while the jaw 2 'remains stationary resting uponvthe-ixed por# tion 30 of the valve devlce. As the movable jaw, is raised it lifts the loose collar 31 of the stem and thus compresses the spring 7 so that access maybe had to thecotter pm I 32 (dotted lines Fig. 5)' or other attention given to the valve device as required. The

lever arms are held in position by crossing one over the other and permitting thefe'ndof' lever 9 to rest between'the lugs 21, and the lever 8 to which it is fixed. l ,In'this manner the spring is held compressed and the: handsare free to perform the work frequlred'.

What I claim is l 1. A device as described Ictn'n'prisiiig v of pivotally joined lever handles, a pair of jaws one of which has a straight line movement relative to the other, and a swiveljointl between each jaw and its handle ,permitting the jaws to swing at right anglesfto the plane of the handles.. I v A I 2. A post a jaw fixed thereon and a jaw slidable on the' post, apair of. lever vhandles pivoted to the `j aws and pivoted together,-

and a swiveljoint between the handles and jaws.

3. A, post a jaw fixed thereon and a par-V allel jaw slidable on the post, a pair of lever handles pivoted to the jaws, and an adjustable pivotal link connecting said handles,

and a swivel joint between ea h handle and its jaw.

In testimony whereof I aix my si ature.
