llo all whom i?. may concern:
Be it known that l, BROR CARL lvnn' i{i,ii.r.oninv, a subject of the King of Sweden, residing at ldasadena, inthe county ot Los Angeles and State of Calitoriiia,'liave invented a nevv and usetnl Valve-Lifting Device, ot which the tollovving' is a speciiication.
This invention relates to means or lifting the valves of gas engines, and the main object ot the invention is to provide a device for this purpose with `iconvenient and effective means for releasably locking; the valve litter in position to hold the valve open.
Other objects oit the invention will appear hereinafter.
The accompanying drawings illustrate an embodiment of my invention, and referring thereto: Figure 'l is a side elevation ot the valve litter in operated position. Fig. 2 is a similar view, showing the valve .litter in released position. Fig. Sis a side. elevation of the valve lifter. Li is a transverse Specification of Letters Patent.
section through the locking device, on line' Fig. 5 is a side elevation ot @the lockingl device, partly in section. Fig. ti is an. elevation of a portion ot the lever showing), the locking device thereon. Fig. 'i' is a side elevation of a portion ot the valve mechanism ot en engine, showing the application of the valve litter thereto.
The valve litter comprises a pair ot levers i. and 2 pivoted together at 3 and provided with torlrs fi for engaging with parts on the valve stem and engine, to litt the valve from its Seat .in vvell known manner.
ill/leans are provided t'or locking the levers 1 and f2 in operated position, said means comprisingI a segmental bar 6 pivotally mounted at 7 on the lever 1 and a locking 'pin 8 mounted in the lever 2. Said lever may have an enlarged portion 9 formino; a bearing :tor the locking` pin S, said enlarged ortion being; formed with a slot 10 through which the segmental har (i slides. Locking pin 8 is provided at one end with a head 12 and at. the other endv with a handle consisting ot a collar lf- 'last on said pin and two Wings 1.3 on said collar, the head l2 and collar 1li engaging with lever to retain the pin on said lever. l'iocliiiig pin 8 is 'formed with a slot l5 and is so located with rei'errotation of fr, he brought so to 4form.

the unslotted portion of the pin may, by suitably turning the pin, be brought into the slot 10 to form an obstruction therein. 'ihe segmental bar G is formed With a series 6o of recesses or notches 17 tor receiving the locking pin, said recesses being preferably rounded so-jas to tit the ,unslotted portion 1'5" ot the locking,` pin, when the pin is turned to locking position. ln order to properly limit the rotative movementof the locking pin, a stop pin or projection 19 is provided on lever 2, adapted to engage with one of the wings 13 on the locking pin, the other WineI 13 being' cut away as shown at 13 to 'm enable it to pass the stop projection 19 Without striking the same.
Fig. 7 shows the manner of application of the device tothe lifting valve of an engine.. The cylinder is indicated at 20, the valve stem 21 being' provided With the usual spring 22 and with. a collar Q3 which is loose on the stem and engages a. pin 24 on the stein. 26 indicates a tuppet rod sliding in a tappet guide 25. so
rihe operation is as follows: The locking pin having been moved to position in which its slot l5 registers with the slot 10 in lever 9:, the said lever is moved to position shown in dotted. lines in 2, and the tool is then slipped into position ou the valve stem one of the jaws el oi the device engaging with the collar Q3 and the other of the jaws engaging with the tappet 25 and the handle portions of the levers are then moved to- @o ward one another as indicated in Fig. 7 and in tull lines in Fig. 2, so to litt the valve. lWhen the valve has been lifted to the desired amount, the handle oli the pin is turned s0 to bring one ot the stop wings 13 thereon @o against the stop projection 19 and in this position the unslotted portion 15 ot the locking pin extends into the slot 10 aud comes into engagement with one of the recesses or vnotches 1'? in the segmental bar 6,' Ml@ thereby locking said bi1-r, and the tool in operated position.
