To all 'whom it may Concern:
'A -Beit-known that l, AUGUSTE DACCORD, a
citizen of Switzerland, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Iinprovei'nents in Shock- Absorbers, of which the following is -a specification.
4The invention relates to certain new and useful improvements in shock absorbers adapted to serve alone as the spring device or as an auxiliary to another spring device.
AlVhile primarily intendedfor vehicles, it
may be employed to cushion'. and absorb shoeks oeeiirriiig between any two relatively moving,r parts.
The primary objectJ of the'I invention is to provide means for` resiliently resisting forces applied betweentwo parts and at Athe same time to retard the action of the forces and 'resistance thereof.
W ith thesc'and other-objects in View as `will be hereinafter pointedv out, reference willbe had to the aeet'impanying drawing formingr Ia part of this specification and wherein like cl'iaraeters of reference designate corresponding parts throughout. the several views, inwhieh:
Figure 1 .is a vertical sectional view through the invention,` Fig. 2 is a similar view taken atright angles to Fig. 1, Fig. Il is a view in elevation of an' upper fragi'nent of the invention, and Fig. 4 is a view in elevatioii of a lower fragment of the invention.
The invention comprises a body portion. composed of front, rear. and end walls, 1, 2, Sl and l, respertively, said wallsrbeing provided with 'a dome cover member The front wall is extended 'upwardly to provide an arm 1. and the rear wall is similarly extend ed to pro\ ide a siiiiilaii-ari'iif'l Extending upwardly from the rover member 5 are arms .oi-'wall portions 1 and 2"', the wall .por-
tion l" beingr spaced trom and connerted iii parallel relation with the arm 1' by Coni'ieetling*r parallel spared wall poi-'tions 11 and l,
and in a similar manner and b v similar means, the walls and 2" are connected. 'lhe eover manila-1: does not extend across the. siaees between. the wall -portions and arms and 1 or 2" and 9.'. A bolt 6 e yeliicle, springs is attached.
complementary vehicle spring-1s attached to 'a holt -O with toggle links 21'aiid vthe lower ends of` the links 18 and .19 are tends through arms 1, 2 and Wall portions 1 and 2 and is rigidly'held by suitable means therein, and to this-bolt one of the The other* or a second bolt 7, which extends through the members 1', 1'?, 2', and 2 and works up and down in vertical slots8 formed therein.
The outer ends of this bolt 7 are suitably se-` cured in plungers 9, one of said plungers being vertically slidahle between members toggle links 1G, 17 are.p,ivotally secured 'to' the vholt 14 and similar links 1'8-ai'id 19 are .Y pivotally secured to the bolt 15 ,'and the said heads 12 occur between said links and the front and rca r walls 1 and 2 respectively of lthe housing. The lower ends of the links 1G and 17 are pivotally connected .by means of 22, and
pivotally connected by means ofv a-bolt 24 with toggle links 25 and "26; and the links 21, 22. 25, 2G are pivotally connected bymeansot a bolt i7. 'The links 9.5 and l 'oei-ur between Athe front and rear housingT walls 1 and 'i and the other links, while only the upper portions ot the links ill. and 22 occur between said front andrear walls and the links 1G and 17, due to the said links 21 and 22 being ofl`set at tlieir-lower ends asA indicated byV numeral 28,' so that the lower portions 21' and 22 of said-*links Z1 and Q2 respectively. come betweenthe lower ends of the links 25 and 2G. The bolt 27 has no movement and its' ends pass through the front and rear housing walls 1 and 2 respectivelyv and through an encircling reinforcing hand 30. one end of said'bolt having and the other end being threaded to receive a nut 27".
A coil spring, substantially rectangular in cross section, and indicated by numeral 31 is arranged horizont-ally within the' housing,
and each end of said spring isprovided with apair of loops 32, each loop bent from a terminal side strand of the spring '31. The bolt 20 extends through the pair of loops at one end and the bolt 24 extends through they pair of loops at the other end of the coil spring 3l. A buffer spring is provided for each of the bolts 2O and 24, each bull'er spring being composed-of parallel free end portions '35..which are bent inwardly at 36 and coiled at 37 to form eye portions, then bent outwardly at 38 into the plane of said portions 35, thesaid portions in vsaid Aplane being connected by a loop portion 39. The bolt 20 passes through the eye portions 37 of one of the bufler springs, and the -bolt 24 passes through thf'reye portions 37 of the other buffer springs. The terminal ends 35 and looped end 39 of one of the Abutler springs bear againstthe inner .face ofthe wall portion 3, while the terminal ends 35 and looped end 39 of the other 'buffer' spring bear against the inner face of the wall portion 4. For. the purpose of repair, upon removing the'bolt 27, the internal parts may be withdrawn as a unit from Within the housing through the open lower end thereof.
In operation, whether force is applied to move the bolt 6 toward the bolt 7 or vice versa, orv whether such force is applied through vehicle springs or other mediums, the relative movement between the lparts is as follows: The bolt 7 vmoves vertically within the slots 8 and the bolt 6 moves vertically within theslots 10, and the `plungers 9 move vertically, downwardly. With the downward movement of the plungervheads 12 within the housing, the
toggle links exerting resisted force against `the stationary bolt 27 arecaused to spread to force the bolts 2O and 9A away 'from each other, which spreading apart of said bolts is resisted bv the tension spring BLand also by the buer springs 'between said bolts and thc adjacent walls of the housing. As these bolts 20 and 24 move toward the adjacent wallsy of the housing, each buffer spring tendsto flatten out against its respectivehou'sing wall, and in such flattened condition slides vertically along said house ing wall and serving in that manner as a friction retarder. Thus the force applied to the bolt 6 or 7 is not only resisted by the springs, but the resisting action is also combined with a retarding action due to the buffer springs sliding along the walls of the hOuSing, and this retardation not only takes place upon the downward movement of the plungers, but also upon the upward movement thereof.
W'hat is claimed is:
1. In a device of the character described, a. housing, a plunger therein, links between the housing and plunger adapted to spread apart, and means pivotally connected with said .links and rictionally engaging the housing to resist and retard such spreading apart action of the links.
