RADIATOR SHOCK-ABSORBERL Specification of Letters Patent.

Patented Dec. 7, 1915.

. Application filed January lt), 1915. Serial No; 3,064.

To all whom it may concern:

Be it known that I, GUSTA" A. LIND- STROM, a citizen of the United States, residing at Menominee, 1n the county of Menoml- 5 nee and State of Michigan, have invented absorbers, and its object is to provide means independent of the usual springs of an automobile pleasure car or truck, by which the radiator will be specially cushioned against jolts and jars during the progress of the vehicle.

cooling water of the system is directed to be cooled by the passage of air from the outside about the tubes. In a great many factories the radiators are put together with tin solder, which does not well withstand 5 vibrations'and repeated shocks, and frequently breaks with resulting leaks in the radiator joints. On most motor trucks known to this applicant the vibrations are greater than on pleasure cars, as relatively stiff springs and solid tires are customarily used. The shocks, jolts and twists to which the radiator are subjected are very severe on trucks, and even on the best cars there is an unavoidable and long continued vibration that has its harmful effect upon the radiator.

In the accompanyin ferred construction 0 illustrated.

Figure 1 is a front view of a radiator to which this invention has been applied. Fig. 2 is an external side view, and Fig. 3 is a vertical section upon the broken line w-.'r of Fig. 2, and showing a portion of a radidrawings the prethis invention is ator attached. In Figs. 2 and 3 the scale of drawing has been increased to show all parts assembled.

Throughout the description and in the drawings the same letter is used to refer to the same part.

explanation of the parts and their arrangement in one will answer for both.

The radiator bracket a supports the foot of the post B, which is usually of the bifurcated shape indicated by the broken lines in Fig. 2. At the top the post has a clamp b and a clamping screw C. The clamp holds the stud D of the upper shell (Z of a .casing, of which the lower shell or part is marked E. The shells are suitably threaded and joined as illustrated in Fig. 1. The

casing is thus connected with the radiator Ar The bottom of the lower shell E of the casing has a central opening 6, and upon the bottom interiorly is a compressible washer F, usually of felt. \Vithin the casing is the cup G that has a lower annular shoulder g resting upon the washer F. The cup G carries the pneumatic cushion or ball H upon which the casing rests, and the cup has a shank-or cylindrical portion J extending downwardly through the washer F, and secured by the screw J to the angle bracket K, which is in its turn secured to the side piece L of-the frame of a truck or automobile. The cup 9 is, therefore, a support for the pneumatic cushion and is connected with the frame.

In the operation of this invention, the vibrations of the frame due to the running of the motor are almost entirely absorbed by the rubber ball or air cushion 'H. In practice it is found that the tremor of the radiator and hood ordinarily so pronounced and noticeable in many machines while the motor is acting, may be damped by the use of this invention properly applied to such an extent as to render the radiator joints practically safe from injury.

When the automobile is proceeding, an

-upward jolt of the frame compresses the ball H between the upper shell d of the casing and the cup G. The casing as a whole moves relatively downwardly and the shoulder 9 and the washer F may be for a moment separated. As the ball H reacts and the radiator is thrown upwardly, the felt washer limits its rise and takes up the jar.

It is thought to be clear that an experi: enced and skilful mechanician may vary the forms of the parts of this invention from those illustrated, and this invention is not restricted narrowly thereto.

When an automobile is in use there are produced frequent lateral shocks to which the radiator is subjected. To absorb such shocks the pneumatic cushion is given such form as to enable it to roll sidewise in any direction. The ball H will so move in the cup G. It is believed to be discernible from anfinspection of Fig. 3 that a sidewise movement of the radiator and casing will comof the cup is smaller in diameter. than the .opening e'in the bottom of the lower shell E. That construction allows the radiator and the attached casing, andthe frame L carrying the cup to move one with respect to the other to a certain extent in any direction horizontally. Or, the cup and casing may turn somewhat one with' respect to the other. As the ball has a free rolling movement in the cup and in contact with the casing, it interposes a cushioning effect whether the shock be vertical orhorizontal or both together.

Having now described this invention, and explained the mode of claim is 1. In a radiator shock absorber, the combination with a radiator, of a vehicle frame,

a casing secured to the radiator, the said casing comprising upper and lower shells, means for removably securing the said shells together, the said lower shell having an opening in its bottom, a cup located within the said shell and having a portion passing downwardly through the opening in the bottom of'the said lower shell and secured to the said vehicle frame, and an elastic ball located within the casing and arranged to support the said casing, the said ball havmg a free rolling movement in any direcits operation, what I ball located within the casing in rolling contact with the top thereof, a. cup. constructed to support the ball movably and arranged within the casing, the said casing having an opening in its bottom, the

said cup having a portion passing through the said opening, means for connecting the said portion of the cup with the said vehicle frame, and collapsible means arranged between the cup and the bottom of the casing within the casing for cushioning the relatively downward movement of the cup.

3. In a radiator shock absorber, the combination with a radiator, of a vehicle frame, a casing connected with the said radiator,

the said casing having an opening, an elastic ball located within the casing in rolling contact with the top thereof, a cup constructed to support the ball movably and arranged within the casing, the said cup being less in diameter than the interior of the casing and having a relatively vertical movement and a relatively horizontal movement in any direction with respect to the said casing, and means extending through the said opening in the casing for connecting the said cup and the vehicle frame.v

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