nnA'Nxs LAN- application sled 'rune 2e, 1920. serial No. 391,986.
To all wlwm t may concern: V v Be i known that I, GEORGE LANzrUs, a
I citizen of United States of America, residing at 9 East 39th Street, city, county, and
vState of New York, have invented new and useful Improvements'in Elastic Shaft Connections, of which the following is' a -speciiication.
This invention relatesto elastic shaft connection arranged to be placed intermediate of a driving element and a driven element for the purpose of maintainin the two elements in alignment and at t e same time serving to reduce the strain upon one or the other of said elements by reason of the un- :balanced condition between the power applied by the driving element and the re Sistance produced by the work accomplished by the driven element. One of the A'objects of the invention is to provide'means for 'limiting the torsional strain in either directionon a Aresilient element forming part of the invention and at the same time to provide a certain gripping of the driven anddriving element.
A'further object of the invention is to provide a resilient gripping member .Which surrounds the ends 'of thev driving and driven elements so that these respective .elements are released when the power ceases to be aplied. One of the objects of this invention 4.1s to provide means for cushioning the shock which accompanies such transmission of motion or arresting of motion from one part to the other 'so as to reduce wear and prevent damage to the parts of the mechanism to which it is applied, and in the drawing l have illustrated the invention in one form of embodiment as applied to the drive shaft of an automobile.
'lhe invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed.
ln the accompanying drawing, .forming part hereof, isillustrated a formjof embodiment of the invention, in which drawings simlar reference characters designate corresponding .parts and which Figure 1 isa plan view showing the ap-V plication ofthe linvention to a common forniof motor driven vehicle;
Figure 2 is a longitudinal section taken through the device as applied to a drive shaft and in normal position;
Figure 3 is a longitul section through vthe device applied to a drive shaft, showing the posltlon of the parts when power has belfit applied to the driven element of the s a i vFlgure 4 1s a transverse section taken apprornmately on line 4-4 of Fi re 2;
Figure 5 1s a transversel section taken ap prox 1mately on line 5-5 of Figure 2;
F lgure 6 is a transverse section between the abutting ends of the shaft, showlng 'the normal pos1tion of the resilient member of thei device or before the power is applied; an
Figure 7 is a transverse section taken between the 'abutting ends of the shaft show- 1ng the position of the resilient member after power is applied.
Referring to the drawings, a shaft D may be cut as at 1 to form two separate parts. A sleeve 2 is dislposed over the abutting ends of the shaft and in the embodiment shown in this application is loosely disthe sleeve 2 may be loose with relation to both ends of the shaft.
An outer sleeve lis also secured with relation to one end of the shaft by means'of the set-screw 5 and collar 3.A rllhe section of the shaft opposite that to which the collar 3 issecured has disposed thereon a collar 6,'
which is fixed with relation to the latter section as by means of a set-screw 7 and the collar 6 is provided with an annular recess 8 arranged to receive the free end of the sleeve 2.
A. coil spring 9 is dis osed around the sleeve 2 and inside of the s eeve Ll. The ends ofthe coil spring are disposed in recesses 10 formed in the collars 3 and 6 respectively. The sleeve 2 is provided. with a plurality of longitudinal slits 11. 'permitting theexpanf sion and contraction of the sleeve, which is made slightly larger than the diameter-.of the shaft D so that shaft.
In the form of ap lication of the inventi'on as shown in the d applied to4 an ordinary wheeled chassis A normallyit does not grip the rawings it is shown as its having the ordinary form of transmission B,
differential C and drive shaft D. y
llnthe operation of the invention, the
sleeve .2 is made of an interior ter slightly larger than the exterior diameter of silience of the sleeve caused by the slits 11 permitsthe sleeve to be contracted against l the shaft D and to tightlygrip the same.
rThe coil spring 9 is disposed around the sleeveQ so that normally no contracting eEect is had. The ends of the coil spring 9 bein secured to the collars 3 and 6,r when one o the sections of the shaft D is driven the coil spring is contractedso as to .contract the s1eeve'2 and firmly grip the shaft, when one of the sections is rotated in one direction. Vihen` rotated in the other direction the spring 9 would expand but its limit of expansion is fixed by the interior diameter the outer sleeve Il, so that in neither case is more strain put on the coil spring 9 than it can bear. t
" Having thus described the invention what is claimed as new and desired to be secured by Letters latent is:
1. ln combination with" a dr1v1ng .and a driven element, means operated by the driving member for keeping the -elements in on the element-s.
alignment and means for compressing the alignment keeping means on the elements.
2. lin combination with -a driving and a driven element, means for keeping the elements in alignment and resilient means for compressing the alignment keeping means 3. ln combination with a driving and a driven element, constantmeans for keepingI the elements in alignment and a member wound around the alignment keeping means and having its ends secured to the driving and ,driven elements respectively.
d. ln combination with rotatablev drivin and driven shafts, a resilient sleeve dispose .over the abutting ends of the shafts and means for compressing the sleeve 'on `the shafts by rotationof either shaft.
5. ln combination with rotatable drivin and driven shafts, a resilient sleeve provide antenas with longitudinal slits disposed over the 4'abutting ends ot the shafts and means operfor compressing the sleeve on the shafts and means for limiting the action of the compressing means.
` 8. ln combination with rotatable drivin and driven shafts, a resilient sleeve disposed over thev abutting ends ol the shafts, a coil spring disposed around the sleeves and havin its ends xed with relation to the shafts an means for limiting the action of the coil sprinjg. t
9. n combination with rotatable driving and driven shafts, a resilient sleeve dispose lover the abutting ends of the shafts, a'coil 'spring disposed around the sleeve and havin its ends lined with relation to the shafts, an a sleeve secured on one end of the shafts and disposed around the coil spring.
l0. ln combination with a driven and a driving shaft, collars on. the shafts, a resilient sleeve connected with one collar ,and Working under the other collar, an enter sleeve connected with one collar only vand surrounding the inner sleeve,` and a coilspring disposed intermediate of lthe sleeve and having its end'sconnected to the coll,
the spring being disposed inside of one sleeve and outside of theother.. lin testimony whereof li have; 'signed my name to this specication.
