GENERATOR SUSPENSION.
Application filed October 29, 1921.
T 0 all whom it may concern:
Be it known that I, ELI J. BLAK a citizen of the United States, and resident of Bufialo in the county of Erie and State of New York, have invented certain new and useful Improvements in Generator Suspensions, of-which the following is a specification.
The invention relates to improvements in generator suspensions, more particularly for use on railway oars where an electric generator is used for lighting purposes. One of the objects of the invention is to provide a simple and elfective arrangement for suspending the generator beneathv the body of the car and maintaining the belt by which the generator is driven from the car axle under suitable tension. Other objects of the invention relate to improved combinations of parts and constructional elements and details, all as will be more fully described in the following specification and particularly pointed out in the appended claims.
In order that a clearer understanding of 25. the invention maybe had attention is hereby directed to the accompanying drawings forming a part of this application and illustrating one embodiment of the invention. In the drawings, 7
Fig. 1 represents aside view of part of a railway car having one'form of the invention applied thereto, one member being shown in section; p v v r Fig. 2 is an end view of parts shown'in Fig. 1;
Fig. 3 is an enlarged section taken on line 3-3 of Fig. 2; w Fig. 4 is an enlarged section taken on line 4 40fFig.1; Fig. 5 is a view similar to that shown in Fig. 1 showing a modified form of construotion; Fig. 6 is an end view-of parts shown in '5 Fig. 7 is an enlarged sectional view taken on line 77 of Fig. 6; and i Fi 8 is a section taken on Fig. i.
Referring to Figures 1 to 4 of the draw? ings, the generator 1 is shown as supported by a pair of support rods 2 2, from an adapter casting 3 which swingsupon a hinge 'or pivot pin 4 which is mounted in the pending arms of the yoke casting 5. The
latter rests upon the channel 6 which is -at line 8 8 or Serial No. 511,373.
tached to the car body, one of the longi tudinal beams of the car body being indicated at 6 7 7 1 The generator 1 is adapted to be driven from a car axle by means of a belt indicated 7 at 7 extending around a suitable pulley 8 secured to the shaft of the generator. It is not deemed necessary to illustrate herein the car axle to which belt 7 extends, the axle,
however, being considered as located to the right of the generator as viewed in Fig. 1.
During conditions of operation the generator will swing about hinge pin 4 towards and away from the car axle in the well knownm anne r. The yoke 5 may be centered on a bolt 9 and may be aligned with the axle by aligning screws 10 which are threaded through suitable openings in a castingll attached to the lower side of the channel 6.
In the construction illustrated the tension a hook 13 which is hooked through an eye 1e formed at the lower end of a hook member 15. This hook member may beisupported by hanging theJsamexover one of the flanges of the suspension yoke 55, this flange having a notch formed thereinin which the hook member 15 rests. The stem portion of hook member 15 projects through suitable openings formed in thewebs of yoke 5 and of channel 6. Y
In the constructionillustrated the opposite or lower end of spring 12 is finished as spring 12 by drawingbar 16 down toward or against itsseat on the flange 18of bracket 19. The double hook arrangement at the lower end of the spring forms an efii'ective abutment against which bar1-6 presses,the details spring 12 is provided at its upper end with .95 provided for the-purpose of extending of this arrangement being indicated in Figs.
3 and 4:, in which it will be noted that surfaces are provided against which the bar 'or rod 16 m'ay rest withthe hooked endportions of thespring below thesame.
i It will be noted'that with this arrange-- ment the tension spring extends downwardly V at a steep angle, greater than 45 to the horizontal, from aconneotion with the car body a substantial component arran e-fem spring acts upwardly at all times so asto op pose the weight of the generator to a,con-
siderable extent. Accordingly the combined spring and gravity load on the hinge pin 4 is correspondingly reduced. Y
In the arrangement shownin the'drawings the sleeve v201ispivotally:mounted on one of the supportzrods 3' Sleeve be properly located longitudinally of t'h e support rod 2bymeans of pipelspa'e er 2-1 positioned; on rod 2 -b etween =-sleves20 and the opposite supporting armof casting 3; Sleeve 20 isinternally--tl1readed and is adapted to receive semen-s ivhichextends out. of the upper end of the sleeveand is provided with r-a =irig idp hand e ivvheel 23; Screw 22- :is provided withyan extensionfla of-. .reduced diameter which passes loosely through an opening iin channeletl iorwthe purpose of properly :locatingnand position.-
'the;'-1.devic e JL semispheric1;v alonse Washer 251s mounted on the extension 24 ofscrew 22 and bears against the shoulder at theupper end of the portion of the screw, the diameter of which is notreduy ed. 1liis;se:nii-spherical washer serves to furnish a hearing' 'against the lower edges of the opening referred to in channel 6, when the screw is screwed upwardly to cause the washer to engage against the underside of channel 6.
The length of the screw 22 up to the end ofuits portion of full diameter is such as to permit the generator to swing away from the axle the maximum desired distance when i 'Crewed down to its lowest position. Then, however, it is desiredto apply or renew the belt 7 the screw is screwed upwardly until washer 25 engagesagainst theiunder surface of channel 6,-as istated fafter which further upward moi s mmer. the screw forces the 7 generator to swingv about its. pivot a toward the car axle, against the resiistan'ce of spring 12 and of -gravity. Jr fter the belt has been reneweduthe, screwaist again turned to its lowest positionand thereafter the extension Q tyrherelyslides through the. hole in the channelnas the generator swingsback and forth until the next occasion for renewing the belt-Li. 7
The constructionshown in 5 to S inclusive be substantially th same as that previously described except in regard to the tensionspring and-its mounting.
The spring 12 is a coiledtension spring which is wound under stress so that ape proximately the minimuin. tension desired incaction is required to start the coils of the spring apart, springs wound with initial tension being .well known.
-, ,A 'sp ring of thischara'cter has various features which are advantageous for the use here described. Since the coils of the spring arelpractica-lly incontact with each other at the beginning of movement of the generator towards ,the axle, it is obvious that less space will be required to accommodate a givenrnumber of turns than would be required if it were necessary to stretchthe coils apartto. attain the initial tension. Also since the length or the spring when released is only slightly less than its minimum length in action wit is unnecessary to [provide a screw for placing the spring under tension. Hence;-i tis poss'ible to apply the spring by swinging the generator a slight distance back of its normalinaxinium. distance from the axle and dropping the spring in place, with a trunnion,v or the like, vat. the lower endwof the spring seated- ,Within. siiitable notches 'or seats on a bracket securedv to the generator. A :As ishownin Figs'.- 5 to i8 of the drawings; the upper end of. 'theispring may be mounted-bymeans' of a hook 15 as spring, however is out off Without forming ice any loop in the same, a trunnion member 26 being provided having a stem portion 27 which is provided with external screw threads of the same pitch as the spring, this stem portion being adapted to be screwed into the lower end of the spring. This trunnionmember is provided with cylindrical extensions 28, 28, transverse to the axis of the spring, these extensions being adapted to rest against curved seats 29, which are formed on the bracket 19 secured to the generator, these seats facing downwardly. The spring is mounted in position by swinging back the generator, away from the car'axle, beyond its normal range of movement, until the extensions 28 of the trunnion can be slipped underneath the notches or seats 29. Thereafter extensions 28 of the trunnion member will be held in position within seats 29 both by the weight of the generator and by the pull exerted by the belt on the generator pulley .8.
It will be noted that the construction described permits adjustment of the tension spring 12 in accordance with whether the stem 27 of the trunnion member is screwed a greater or less distance into the convolu tions of the spring before the spring is secured to the generator.
It should be understood that the invention is not limited strictly to the details of construction described but is as broad as is indicated by the accompanying claims.
What I claim is:
