To all whom it may concern Be it knownithat I, WI-LIJAM T. Home- MAN, a citizen of the United States, and a resident ofChicsg'o, in the county of Cook and State of Illinois,have invented .certain new and useful Improvements Adjustable Connections for Switches, of which thefo'llowing I is a specification.

My inventionrelates'to an improved adjustable "connection for switches particularly adaptable forconnecting switchipoints with the operating trainfrom a local switch Stand or from-n tower.

r In the operation- :of switches the throw of the switch "lever and oonnectillg =train is :us'ua lly i reater' than 1 the necessary ithrow of the' swi-t h to open or closedposition and meams must' be provided to adjust or compensztte 'for:suchidifi'erence. In Patent No.

In the arrangement of the patent the end of the operating train from the switch stand or tower is in the form of a, head 'shiftable 'between edjustable abut- 1 I merits-connected with the switch bymea'ns of whichf adjustment can be made' so th iit shifting efthe opereting train in one'di'rection or the'other will'ca'use eeeh'reteend safe closure or opening of the switch, "or safe as deralls.

'On the accompanying drawing construction and arrangementus shown which cmbodios the above-and other features of my invention. On this drawing- Figure 1 is e'perspectivevimv'showing the application of my adjustnble connecting device to aswitch,

A represents my improved adjustable connecting-device which is secured to the tie-bar t end into which extends the rod 10 whichis connected to be operated from a local switch stand orfrom a tower.

The device comprises a cylindrical housing :11 having the lateral extension c by mea s of which it may be secured to the switch or other device to be controlled. The ends of 'the housing are of reduced diameter andinternstlly threaded as indicated at 12 and 13 forreceivi ng the adjustablc zibutmerit plugs Hand 15. Therod 10 extends through' the hore 16 of the plug- 14 and terminates in the abutmenthead 17. Asjthc rod 10 is shifted lo gitudinally from the switehetend or tower'tl'ie head 17 is brought into engagement'with the inner end of the respective plug 'to shift the switch or other device'to be controlled, the relative movement betweenthe head and 5 housing determinedhy t'he a'djustinentof the plugs being such its will compensate for t'he difference in throw between the switch lever and the desired throw 'of bhe switch oflother device. It has beenf0und ths'itt-he switch points and the adjustable connecting attachment secured thereto are frequently shifted I relati'veto "the switch -stend"-or operating train so thettheakis of 'theconhecting rod 10 will tend to assume an angle with the' zrxis of the housing and this will of course immediatel cause loindingif'no provision were made-for reventing I, however, prevent such bindiiig b pehn'itting' lateral pity of" the red 10 l in the housinglll, and this I accomplish by making the diameter of the bore of plug14: greater at its inner of the rod. In Fig. 2 the bore 16 is tapered 5 01' conical and-Lfits" the rod 10 onlyat, its f outer-"end.- Thisper'mits lateral'play of the 10. section of the housing 11 issufliciently great 7 V to accommodate the a lateral play of the rod 10; 1 r
