'Figurelais a perspective view ofa spring litter or compressor constructed'in accordance with the invention.
Fig. 2 is an enlarged, fragmentary, vertical sectional view.
v Fig. 3 is a detail vertical section'through the free end of the valve holding arm, showing the relation of the valve holding finger with said arm.
Fig. 4; is a detail vertical sectional view v otholdi g its dog,22 released, whenthe two through the spring engaging foot and asso ciated parts, showing the manner of connecting said foot with a lower arm of the device.
In the drawing above briefly described, the
numeral 5 designates a vertically'disposed '25,ith'e' front'end ofsald lever'being preterably formed with two 'turcat ons 26 which shank having downwardly facing ratchet teeth 6 on one edge. The lower end of'this shank is provided witha T-head"? which is received in the channel 8 of a 'channel meta-l horizontal arm 9, the side. flanges of said arm beingformed with longitudinally spaced openings 10 through any of which a cotter pin 'or the like 11 may be passed, one end portion of the head 7 being formed with an opening through which'this pin also passes. Thus, not only may the arm 9 be adjustahly connected with the lower end of the shank 5, but said arm may be upwardly swung to an out-of-the-way position, when its use is not necessary and the tool is to be placed in a tool boa or the like. I p v The bottom 12 of the channel metal arm 9, has a notch 13 formed in its freeend, said notch receiving the upper end, of a'vertically elongated plate 1 L whose rearedge .abuts'the inner wall of the notch. This plate 14 car- 4, 1926. Serial. No., s5,9s'e.
ries abifurcated'foot 15 to; straddle the lower end of a valve'stemand engage thelower extremity oi the valvesprlng' The rear end of this. foot. is fform'ed with an upstanding legportion 16 of channeled' t'orm, said leg portion receiving thebody of the plate'vl l and being "connected deta'chably with the latter by means of a cotter'pin orthe like 17, passing through 'alined openings in the leg and plate. "The upper end of the plate 14;}is riveted as at 18 to the-side flangesofthe arm [9. fEngageme-nt of; the upper-fend of'thefleg 16, withltjhe lower side of the 9,:l'1'0flds theplate 14c andthefoot .15 against anypivlotalaction with respect to said arm;
,The' details just described permit the at t'a'chment of feet'of different ldesignstoj the arm 6 9, according to the conditions encountered onj difierent, motors. Preferahly,;each
"foot 15 and its leg portionltl are pressed or drop-forged from a sin'glr'e bodyot' n'etal, for ease in manufacture.
An upper, relatively large slide 19,.and a lower, comparatively "small slide Q O; are
mounted onjthe shank 0, said 'sl'ides being provided with upper and lower dogs 21 and 22 respectively," for coa'ctio'n with the ratchet teeth '6. jPre'ferably, ahand actuatedyoke 23 is pivoted to'the slide for the purpose slides and the shank [must ,be "rapidly ad- 'justed, as when applying or removing-the the .t'urcations 26 while their lower ends are pivoted at 30 to the slide 20. By'this arrangement, the slide 19 being held against descent as will hereinafter become apparent, upward movement of lever 24': forces the links 28 and the slide 20' downwardly upon the shank 5, the dog 22 then clicking over the ratchet teeth 6 in readiness to operativel a enga e the last tooth over which it clicks. Then, depression of the lever 24, pulls upwardly upon the links 28 and slide 20, and the 22 then lifts the shank 5, causing'ugjiward movement of the arm 9 and foot- 15, to compress the valvesprir of in. a n1 i 'i he tront. edge the slide 19 is'previded with an integral, forwardly projecting lug 31 which extends into the channel 32 of an upper channel-metal arm 33, the side flanges of this arm being pivoted to said lug 31, as indicated at 34, so that the arm may be downwardly folded when not in use. Received 1n the channel 32, which channel opens downwardly, is a horizontally elongated head 35, said head being adjust-ably connected with the arm by a cotter pin or the like 36 passing through an opening in the head and adapted for engagement with any of longitudinally spaced openings 37 which are formed in the side flanges of said arm. The head 34 is provided, preferably at its front end, with an integral, downwardly projecting finger 38 of cylindrical form. The lower end of this finger is adapted to engage the valve whose spring is to be compressed, said lower end being preferably pointed as at 39. Threaded as at 40, upon this finger 38, above its pointed extremitv 39, I prefer to employ a dome-like valve engaging member 41, so that both the point 30 and the member ll, or either of them, may be engaged with the valve, as occasion may demand. It will thus be seen that while the foot 15 is pulling upwardly upon the valve spring and the usual washer with which it is engaged, the valve is held against ascent, even should said washer bind to quite an extent upon the valve stem.
The device is rather simple and inexpensive, yet will be exceptionally desirable, its primary use being in garages or repair shops, in which the mechanics must be in readiness to effectively work upon machines of all makes. The device may be quickly and easily applied, easily operated to compress the valve springs, and quickly and easily disengaged from the motor after valve parts have been reassembled.
As excellent results are obtainable from the details disclosed, they are preferably followed. However, within the scope of the invention as claimed, variations may be made.
