SLACK-ADJUSTER FOR CAR BRAKES.
SPECIFICATION forming part of Letters Patent No. 398,257, dated February 19, 1889.
Application filed May 7, 1888. Serial No. 273,123. (No model.)
To all whom it may concernlt Be it known that I, U'i-IARLlls U. lnl'ul'lLwM, of Rome, county of Oneida, and State of New York, have invented an Improvement "in Slack-Adjusters, of which the following description, in commotion with the accompanying drawings, is a specifieation,like letters on t he drawings represeu ting like parts.
This invention relates to slack-adjusters especially adapted, among other things, to be used on ear-brakes, substantially as shown in my United Stales patent, No. 252,662, granted tome January 24, 1882, my present invention being an improvement upon the slack-adjuster shown and described in the said patent.
My invention therefore consists, essentiall y, in a slack-adjuster, a shell or case, and
a rod having its end threaded and extended into said shell or case, continued with an adj listing-nut mounted on said rod and by which the said rod is moved with relation to the said shell or case, and with a looking-nut to secure said rod in :uljusted position, substantially as will be deseribed.
Other lel'ilure's of my invention will he pointed out in the claims at the end ol' this speei fleal ion.
Figure l is a longitudinal seetion ol. a oartruek provided with a slack-adj uster embodying my invention; Fig. 3, a longittulinal section of the preferred form of slacleadjuster, the rod and lever heinglnroken oili; and Figs. 3 and -l:longitudinal sectionsol"modified Forms of slack-adjusters.
The link u, connected to the power for op erating the brake-shoes 11' 11 the llllliN u u, and lovers o a" are all substantially as in the patent reterredto. The link or rod 1;, jointed atone end to the lever o,has at its other end screw-tlu'eads which enter and cooperate with a shell orhollow ease, I", pivoted at If to the end of the lever u. The end of the shell or case I) farthest l'rom its pivot isprovided with an opening, Z1, to enable the rod Z) to be extended loosely into the shell or case, more or less, may be desired, the threaded end of the rod not, however, (mgaging the shell or lltbfiflll'tlbi l)". The shell or case I) isalso provided with aflange or lip, as it", against which abuts a shoulder, e, of an adjusting-mit, It, screwed upon the screw threaded end ol' rod 11, the flange or lip Z" in Figs. 1 and '3 be ing shown as threaded on its outer surface for the application to the shell or case ot a locking-nut, e, which hy its rotation upon or against a part of the flange or lip causes the shoulder c of the adjusting-nut to he drawn against the said flange or lip.
The outer end of the adjusting-mil, U will preferably be made hexagonal, or other than round shape, to facilitate turning the same on the red, the rotation of the nut b" enabling the effective length of the rod 71 to be lengl honed or shortened, as desired.
As shown in Fig. 2, the locking-nut c is threaded internally [or a portion ol its length to engage the threads on the flange or hp 1), the rear portion on the said locking-nut being made thicker, as herein shown, to present a laee or shoulder, to bear against the shout der 1- ol' the adjusting-nut; I)" and compel the eollure to be seated against the flange or lip l) to loelc the adjusting-nut in :nljusted po sitiou, the outersurl'aeeol' the rear porlion ol' the loekingnut e being made hexagonal, or other than round shape, to laellilale turning the same as with a wreneh.
To compensate for the wear ol' lhe l)l.ll\'lshoes, the rod (1 may be drawn or extended into the shell h by unserewing or loosening the loehiugmut e. on the rod I; and then t'ot'ating the illljllfitlllg-llllii I! in the proper direction to cause the end olf the rod to extend l'orlhe proper distance into the shell. or ease, and alter the adjusting-nuthas been turned sullicie'ntly to bring the brake-shoes again intoproperposition l-he loeking'nut I" will be again brought into lirm engagementwiththo flange or lip I1 and turned unlil the collar 11 of the :nljusting-nul is lirmly sealed and held z'lgl'illlist the flange orlip It" ol' theshell or ease.
Il' preler the eollsllllei'ion shown in Fig. '3; but good resulls may be obtained with tho lUllHit'llOtlUll shown in l igs. I and -l-.
As shown in Fig. 3}, the :nljusl-ing-uul I) is extended l'rom within out thrt'iugh the end ol. the shell and the locking-nut is screwed on the red (I. The shell or bar [1 may have ex tended through ils opposite walls set-screws 1 only one of which is shown, by which. to take up the eml-t-hrust ol. the :nljustingmut.
Referring to Fig. 4:, the locking-nut e is placed inside the shell or case and bears 1 into said shell or case, combined with an adag'amst the flange or lip I) as the said nut r" l jnsting-nut mounted on said. rod and by rotated on the tin-(aided rod.
The nut r in Fig. ihas sockets a" For the rece t en oi" p'n or other rod by which to turn the said loe.l\'in '-nut.
\\'ith the slack-adjuster shown in Fig. I the locking-nut is turned down on the rod suliieientl v to uncover the :nljusting-nut,
which is turned to move the rod 1 into the shell, and when the adjnsinn-ait has been made the locking-nut is again screwed into the position shown to cover 1 he adj nsti ng-nnt.
\Vith the slack-:nljusi er shown in Fig. 4 the adjusting-nnt is rotated and the rod and the locking-nut moved i'orward into the shell, the locking-nut being moved away from the end of the shell, and thereafter the lockingnut is rotated back upon the rod into the position shown m eontact with the end of the shell.
The opening in the shell or ease, through which the threaded. rod is extended, is i'nade of larger diameter than the threaded end oi the rod, so that the threads on the rod will not become jam med by vibrations of the eartruelcs, the said jar being taken up by the projecting em If oi the :nljusting-nnt.
'lhe lip or flange 0', as shown in Figs. 2 and 7 4:, is recessed to form a socket to receive the pro ecting; end Zr of the adjusting-nut, the 1 said projecting end receiving the strain due to V brations, thus preventingthe threaded portion of the rod from becrm'ling jammed.
I claimwhich the said rod is moved with, relation to the said shell or case, and with a l('l(".l(ll'i {'-llllt to secure said rod in adjusted position,snbsiantiall as described.
2. in a slaek-adjuster, a red, (I, having one end thremled, and a shell or ease having a projectingflange or lip, I)", and provided with an opening through which is extended the threaded end of the said red, the said openingg'beingot greater diameter than the threaded end of the said rod, combined with an adjusting-nut having a shoulder, and with a locking-nut, the shoulder of the adjustingnut and a part of the said locking-nut hearing against the said flange or lip and by the rotation of the locking-nutseating the shoulder firmly against the said flange 0r lip, substantially as described.
3. In a slack-adjuster, a rod, 1), having one end threailcd, and a shell or case having a flange or lip, b", recessed to form a socket, and provided with an opening through which is extended the threaded end of the said rod, the said opening being" of greater diameter than the threaded end of the said rod, combined with an adjusting-nut and with a loeking-nut, substantially as described.
In testimony whereof I have signed my name to this specification in the. presence of two subl scribing witnesses.
I. In a slaek-adjuster, a shell or ease and a I rod having its end threaded and exiemled
