Specification of Letters Patent.
Application mea'octp erjas, 1914'. serial-Na. 868,284.
To all whom it may concern Be it known that I, JOSEPH JAc UEs JuLEs SAUVEUR, a subject of the King of Great Britain, and residing at the cityof Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Shock-Absorbers; and I do hereby declare that the following is a full, clear, and exact description of the same.
The invention relates to a shock absorber and the object is to provide a device of this character, simple to construct and having certain adjustable features which greatly increase the efiiciency of the device and secure its applicability to varying conditions of load.
The invention will be better understood with the aid of the accompanying drawings in which Figure 1 is an elevation showing the invention applied to a vehicle spring. Fig. 2 is a perspective view of the device separated from the vehicle spring. Fig. 3 is a vertical sectional view. Fig. 4 is an under side plan view.
The device is built up of a number of component parts of which the opposite 'side rods 1 are distanced and coupled by plates 2 and 3, upper and lower respectively, the former being rigidly secured on the rods 1 and in any suitable'manner and carrying a stuffing box 4. Between the upper and lower plates, a cylinder 5 is secured centrally between the rods 1, this cylinder being a simple open ended tube and engaging the plates 2 and 3 by fitting in suitable recesses 6 therein. This cylinder 5 is held very tightly between the two plates by the clamping nuts 7 threaded on to the threaded lower end of the rods 1.
' The upper ends of the rods 1 form journals for a pivot pin 8 which is passed therethrough and through the looped outerend of the vehicle spring 9.
10 is a cup shaped piston loosely fitting the cylinder 5 and having a piston rod 11 extending upwardly through the stuffing box 4 and provided at its upper end with an internal thread 12 engaged by the shank 13 of a fork 14 through which a pivot pin 15 is passed into engagement with the curled outer end of the vehicle frame 16; thus it will be seen that the piston 10 moves up and down. within the cylinder 5 as the body of the vehicle moves over' a rough surfaced road.
17 is a plate loosely disposed within the bottom of the cylinder 5 between which and the upper end of the piston 10 a spring 18 1s disposed. A second and shorter spring 19 assisting the main spring to take up any extraordinary shock may be disposed within the spring 18.
As thus far described, the invention would be hardly suitable for varying loads and I therefore provide an adjustment of the springs in such a manner that they may be readily regulated to suit a light or heavy load. This adjustment is accomplished through the medium of set pins 20 threaded through the bottom plate 3 and abutting the plate 17. The set pins 20 are preferably four in number at distanced points as it is necessary that the plate 17 shall be notallowed to tip. It will be seen thatif there are any breakages, it is a very easy matter with this particular construction to quickly take apart or separate the device and put in a new part to replace the broken part.

Of course, I am aware that it is not new to apply a shock absorber between the parts 9 and 16 as illustrated in Fig. 1, but this view is provided to assist the better understanding of the invention, the operation of which will readily be understood from the foregoing description of the parts.
In the stufling box 4, in place of the ordinary packing, is provided a metal bushing 21 which, being oiled from a suitable oil cup, facilitates the sliding of the piston 11 and when worn can be easily replaced by simply removing the stuffing box nut and unscrewing the piston rod from the fork 14.
What I claim is A shock absorber comprising, a pair of' connecting rods, means of connecting the same to a vehicle body, a top plate fixed to said rod and provided with an opening, a bottom plate inwardly mounted on said rods, a cylinder adapted to be clamped between said plates, nuts threaded upon the lower ends of said rods and adapted to force the lower plate into clamping position, a cushioning spring within said cylinder, a cup piston slidable within said cylinder and partially inclosing said spring, a rod extending from said piston through the opening in the top plate, a connecting fork carried thereby, a pressure plate resting in the bottom of.
said cylinder and seating the aforesaid Signed atlMontrealyQuebec Canada, this spring, and a plurality of set screws equally 2nd day of J uly, 1914. spaced about the center of the aforesaid bottom plate and threaded therethrough JOSEPH JACQUES JULES SAU'VEUR' into engagementwith said pressure plate to Witnesses:
