JARED E. GAYLORD, OF BRIDGEPORT, CONNECTICUT.

I e eificationof Letters- '7 A e l t on filed .l'u1y17,1908.1.Seria111b.14 3,9497, i

" vnnvE-nIrrER'iioR Exerosivaseemes Connecticut, have inventeda new and useful Valve-Lifter for Explosive-Engines, of which the following is a specification.

This invention has for its object to provide an inexpensive andeasily operated tool for liftingt e valves of explosive engines.

It is of course well understood by those at the with" considerable power, and furthermore that it is frequently necessary to raise the valves. This is especially true with auto- I Heretofore, so far as I am aware, no special tool or implement has been provided that would lift these valves, easily and retain them lifted. On the other hand, it is a common practice to pr these valves up, with various tools ill a apted. to the purpose and liable to slip and with great I danger of injuring the hands of the operator.

My present invention is provided with the necessary adjustments to adapt it for use upon'dilferent engines and to lift a valve against the power of any spring likely to be used and without the slightest danger of the operator bruising his hands or-injuring them in any way.

With these objects in view I have devised the simple and novel valve -lifting tool, of which the following description in connection with the accompanying drawing is a specification, reference characters being used to indicate the several parts.

Figure 1 is a plan view of my novel tool, the fulcrum rod being in section; Fig. 2 a side elevation illustrating the operation'of my novel tool in lifting a valve; Fig. 3 a detail view partly in section and on an enlarged scale, showing the manner in which the bearing washer under .a spring is .eri

and is provided near its forward end with a no bearing washer is used.

series of holes ;indicated by 15, and at its rearendwith other holes,"'indicated b 16.

At-the" forward end'of the shank is a yo e 17 to which the lifting cup 18 is pivoted. The bottom of the cup is provided with an opening 19 and a slot 20 leading into said 0 ening which receives the valve stem' freely. A flange 21 surrounds the edge of the cup and prevents the washer or base of the sprinfrom slipping out when pressureis applie to raise a valve.

In order thatthe cup may be self-adjusting to the plane of the washe'r or base of the spring, I provide arms 22 on opposite sides 'of the central opening, the upper ends of [resented Jan. 5,1909. v

rod passes freely through either of the holes 15 and may be readily shifted from one hole to another to change the fulcrum by drop' ping it down and swinging it over, the hook passing readily into or out of either'of the 1 The nuts upon the threaded end of o the fulcrum rod need not be removed in shiftoles.

ing the rod and give ample adjustment as to height of the fulcrum.

28 denotes a retaining hook whichmay or may not be used to hold down the outer end of the shank when it is desirous to hold a valve raised as in full lines in Fig. 2, the hook being engaged with any fixed portion of the engine or the machine.

29 (see Fig. 4) denotes lifting hooks which are pivoted to the ears upon the yoke and may be used instead of the lifting cu if found more convenient, for example, w en 2 Under ordinary conditions, however, I have found the lifting cup most convenient. Either the lifting hooks or the arms of the lifting cup are secured between ears 23 on yoke 17 by means of headed pins which are retained in place by cotter pins 31.

The operation of my novel toolin lifting a valve will be readily understood from Fig.

. 2. If a bearing washer is'not used under the spring, hooks 29 may be used as in Fig.4. If a bearing washer is used, the lifting cup Wlll be found most convenient, in fact I pre erably use it under all conditions as it does away with all danger of the operators bruising his hands. The special manner in which the tool is a plied is unim ortant. The erator may first place the ifting cup, or t e hooks as preferred, (see Figs. 3 and 4), under the spring and may then adjust the fulcrum rod and the fulcrum, or he may first place the fulcrum rod in position as in Fig. 2and then place the lifting on or hooks under the spring. It will be note that the lifting cup and hooks both swing on the yoke so that the lifting pressure applied to the spring is always vertical, that the fulcrum rod may be adjusted on the shank without removing the-nuts by sim ly passing the hook throu h either of the ho es 15, thereby enabling t e operator to place the fulcrum wherever may be most convenient, and furthermore that the height of the fulcrum may be adjusted to suit the requirements of use by simply turning the nut or nuts up or down on the fulcrum rod. Having ad usted the tool in the manner described and placed the lifting cup or lifting hooks under the spring, the spring is lifted by ressure applied to the rear end of the shank as indicated in Fig. 2. Having raised the spring it may be locked in the raised position by the use of retaining hook 28. Having thus described my invention I claim:

1. A tool of the character described comprising a flat shank having a series of holes, a anged swingin cup depending from one end of said shan and a fulcrum rod having a hook and ada ted to be passed through either one of the oles in said shank.

2. A tool of the character described comand a fulcrum rod ad prising a fiat shank having a series of holes and formed as a yoke atone end, the armsof said yoke having cars, a flanged swi cu pivotally connected with said ears, an

a fillcrum rod havin a hook and adapted to be passed through either of the holes in said fi shank. I

3. A tool of the character described, com prising a lifting cup having an opening to re-, ceive a valve rod, a slot leading into said opening and a flange surrounding its edge, a shank to which the lifting cup is pivoted 'ustably connected to the shank.

4. A tool of the character described, comprising a flanged lifting cup which is adapted. to receive and retain the lower end of a spring, is provided with a slotted opening to. receive a valve rod and with upwardly ex-: tending arms, a shank having a yoke to which the arms are pivoted,. ermittin the cup to swing freely, and a flfidrum ro' adjustably connected to the shank.

5. A tool of the character descrihed,foom-. prising means for engaging and supporting a spring, a shank to which the supporting means is pivoted and which is provided with two series of holes, a fulcrum rod having ahook adapted to be passed through either of the holes in one series and having & fulfi fllm nut, and a retaining hook for holding a valve in the raised position, which is adapted to engage either of the holes in the other series.

In testimony whereof I affix my signature, in presence of two witnesses.
