Description

Aug. 18, 1931. J. A. WILTSE VIBRATION REDUCING DEVICE Filed Jan. 8. 1930 J.A.Wiltse Patented Aug. 18, 1931 UNITED STATES PATENT OFFICE JEROME A. WILTSE', F FREMONT, NEBRASKA, ASSIGNOR TO THE VIBBAGHEK. COMI- PANY, OF FREMONT, NEBRASKA VIBRATION REDUCING DEVICE Application filed January 8,
This invention relates to a vibration reducing device particularly adapted for use in connection with internal combustion engines or the like vibration producing ma chines.
An object of the invention is to provide a means whereby the vibration generated by the moving reciprocating parts of an internal combustion engine will be partially elimiw nated and thereby eliminate or reduce the annoying rumbling noises generated wlthin a sedan body of an automobile.
Another object of the invention is to provide a means whereby the small fittings of an automobile, such as bolts and nuts, will be prevented from becoming loosened and subsequently lost.
A still further object of the invention is to increase the horse power of engines.
A primary object of the invention is to provide a device which will reduce the vibration generated by .an internal combustion engine, said device to be readily attachable by the owner or user of the engine or automobile after the latter has been manufactured.
Other and further objects and advantages of the invention will be understood from the following detailed description, reference 3 being had to the accompanying drawings wherein:
' Figure 1 is a side view of an internal combustion engine and automobile frame certain parts thereof being broken away and showing in section, the new device being shown in section and applied to the engine in a position of use.
Figure 2 is an end view of the engine and device shown in Figure 1. Y
Figure?) is a face view of an asbestos cushion employed.
Figure 4 is an end view of a resilient bushmg. Y
Referring now to the drawings for a more particular description in which like numerals of reference designate like or corresponding parts throughout the several views, the numeral 10 indicates generally an internal-combustion engine of any conventional 60 type. The engine is provided with a crank 1930. Serial No. 419,442.
shaft 11 having a plurality of cranksor throws 12, some of which are indicated by dotted lines. A fly wheel 13 is, in accordance with the conventional practice, rigidly secured to the crank shaft 11.
The engine is provided with a plurality of reciprocating pistons 14, which are adapted to communicate motion to the crank shaft through their connecting rods 15. The engine may be of the internal combustion type and provided with the conventional arrange ment of a carburetor, an intake manifold, an exhaust manifold, spark plug and a source of fuel supply, not shown. The piston 14 is adapted to have reciprocating movements within the walls of its cylinder 16 in a Wellknown manner.
The new device comprises a standard or support 17 which is preferably formed circular in plan and secured to a plate 18. The faces of the standard are preferably smooth and in alignment or vertical parallelism with respect to each other, as shown in Figure 1.
The plate 18 and the standard is rigidly secured to the engine by means of suitable bolts or keepers indicated at 19. The plate may be of any suitable size or configuration to accommodate the several various conventional types of engines in use today and it will be understood that the plate may be secured to the engine at any suitable location.
The preferred position of the new device is on top of the engine, since when so positioned it is out of the way of the engine accessories 5 heretofore mentioned.
Thesupport 17 is preferably provided with a central bore 20, within which a sleeve or bushing 21 may be fitted.
The bushing '21 is preferably formed of resilient material such as rubber and is provided with a central bore or aperture 22 which is adapted to receive an elongated shaft or bolt23.
Preferably two weights are slidingl y carried by the bolt 23; The weights 24, for convenience of assembly upon the bolt 23, are w provided with elongated apertures 25 which are adapted to snugly receive the bolt 23.
A cushion 26 which is preferably formed of material such as asbestos clutch linings is positioned between each weight 24 and the opposed faces of the standard or support 17 for purposes later described.
The bolt 23 is provided with a head 27 which is adapted to prevent the adjacent weight from moving an undesired distance away from the support 17. The shank of the bolt opposite to its head 27 is provided with screw threads and is adapted to receive a rotatable nut 28. A washer 29 is preferably positioned upon the bolt between said nut and the head of the bolt. A resilient normally expanding spring 30 is carried by the bolt and is adapted to exert pressure between the washer and the adjacent weight. A cotter pin 31 is preferably provided and received adjacent the end of the bolt forv the purpose of preventing unauthorized persons from readily removing the nut 28. i
It is well known that vibration is particularly noticeable in four cylinder engines. The new device is adapted to oppose, neutralize and minimize vibration created by the engine, said opposition to said motion being in a plane parallel to the face of the support 17.
It is Well known that the main part of the movements created by the vibration of the engine istransversely of the engine or of the frame 32 of the automobile.
In operation the reciprocation of the pistons within the engine sets up a vibration thereby shaking all parts of the automobile.
When the new device is installed as above described the weight or weights will have corelative movements with respect to said vibratory movements of the engine and will neutralize, orminimize said latter motion on account of the weights contacting, in alt-ernation, with the support. The shims or cushions 21 prevent undue wear, seizure or freezing port.
The nut 28 may be adjusted to provide a desired tension of the spring 29 to accommodate the individual requirements of aparticular engine. vide means whereby the weights may move away from the fsupport a slight distance and be returned toward the support by means of a resilient member such as the spring.
From the foregoing description it is thought to be obvious that a vibration reducing device constructed in accordance with my invention is particularly well adapted for of the weights with their sup- The desideratum is to pro- .ried by the support adapted to be actuated in movements where-by on the movement of the support in one direction, the weight is disposed against the support and on the movement of the support in the opposite direction, the weight is disposed away from the support, whereby vibratory movements of the engine are adapted to be reduced by the said movements of the weight.
2..A vibration reducer for a mounting on an engine,comprising a rigid support carriedby the engine, a shaft carried by the support, and a weight slidingly carried by the shaft.
3. A vibration reducer for a mounting on an engine, comprising a rigid support carried by the engine, a weight carried by the support, and means for causing the weight to normally engage the support.
4:; A vibrationreducer for a mounting on an engine, comprising a support rigidly secured'to the engine, a threaded shaft carried by the support, a weight slidingly received upon theshaft, a spring carried by the shaft for causing the weight to normally engage the support, and means including a rotatable nut upon the shaftfor adjusting the tension of the spring. I
5.- A vibration reducer for a mounting on an engine, comprising a rigid support carried' by the engine, a weight slidingly carthe support and the weight.
In testimony whereof, I have aifixed my use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the spirit and principles thereof and for this reason I do notwish it to be understood as limiting myself to the precise arrangement and ried by the support, and a cushion between 1
