2 SHEETS-SHEET 2- TJTE V oomvncrroiv rinwsrlvrnivmq Q To all whom, it may concern Be it known that I, STANLEY W. HAYns, a citizen of the United States, residing at Geneva, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Connection Adjustments, of which the following, taken in conjunction with the accompanying draw full, true,

ings, forming a part hereof, is a and concise specification.

This invention is an adjustable connection device for the operating lines of track or signal appliances adapted for insertion between the operating and operated elements eral preferred modes in which I have con templated embodying the same.

Figure l is a longitudinal sectional view Fig. 2a horizontal section; and Fig. 3 a top plan, of a connection device embodying the invention; Fig. 4: a'tra-nsverse section on the line ab of Fig. 1; Fig; 5 islan al ternative form, in longitudinal section; Fig. 6 is a central longitudinal section of a further embodiment of the invention with the cover removed; Fig. 7 is a top plan thereof} and Figs. 8 and 9 are respectively cross-sections, on lines 88 and 99 of Fig. 7 Fig.

10 is a'central longitudinal section of a further form showing the provisions for adjustment of the length of the operating line as well as of the lostmotion therein; and Fig. 11 is a cross-section of Fig. 10 in the line 11-11. I v

The device comprises a frameor casing 1, which has suitable provisions for'attachment to either the operated or the operating element of the operating line, as the case may be. Such provisions may consist of a connection jaw 2, formed integrally on the Sipecification of Ltterslatent. V I Appficatien filedDecember 16, 1908. S'eria1.'i\ To. $7,908.

= Simplification of the structure and facilenact the cas ng, as indicated in meanwings, or the form of theattachment may be modified according to'the nature orconstruction-of the apparatus with whichrused, or thesald attachment "means may be formed as the coiiperati-ve part of the provisions for ad ustment of thelength of the operatmg l1ne,'"as later described; The device is connected with the other elements of. the operating'li'ne by means of therod 3, which terminates with connection-eye 4 or other (suitable connection -mean s',' desirably one rren 4 srANLiiY wanes", 01 mtav gaewsheafQ5l 7' "mantaar s, was.

that will hold; the rod against rotation,

The said rod 11 is! supported for longitudinal movement within the frame or casing, and is threaded at its terminal portion to receive an adjustable collar or nut 5,which latter has a limlted longitudinal movement "with respect to said-casingbut-isheld thereby against rotavtron upon' the rod.- :Adjustment :of the devlce may be,- accomplished by rotating the rod within the relatively stationary nut and easing, or revolvinglf the latter about the rod, according to which: end of the device has been "disconnected for thepurpose.

The casing is byypreferencea closed receptacle' or inclosure for theinut and rod, and the latter enters-the interior chamber througha boss 8. which affords an appropriate bearing. therefor and holds the rod LinaXial alinement with therest of the de =vice.;,- Th bearing in the-boss is of sufiicient lengthv to render. unlikely the entrance of dirttherethrough to the;..interior chamber.,

The said chamber has preferably an angular cross-sectional shape ;-to conform to the shape of theinut, and thus hold it against rotation. In the form shownin Figsil to 4' the nut is square andtheichamber is shaped accordingly; the enlargements shown at the ends of, the chamber being merely to avoid sticking from imperfectly cored castings The end .wall of the interior chamber that is nearest the entrance of'the rod and marked ment, the conical recess serving vat such timesto centrallze therod and preserve it as to against lateral distortion within the chamber. By adjusting the nut or collar longitudinally along the threaded rod, in the manner above indicated, the effective distance between the abutment surface of the nut and the end of the rod may be so varied with reference to the casing abutments with which they respectively co-act, as to provide any desired amount of lost motion within the predetermined limits of the device. The bore through the bearing boss 8 is preferably somewhat larger at its inner end than at its outer extremity, as indicated at 9, so afford sufiicient clearance for the threads on the rod and prevent their mutilation during their reciprocating movement therein; and as a further safeguard against injury to the threadedrod, the-nut is conlined thereon by a linch-pin 10 secured in a hole bored through the end of the rod, thereby preventing over-adjustment of the device to such a point that the number of threads left in engagement with the nut would be insufficient to resist the strain thereon.

In order to assemble the foregoing structure, the closed casing is formed in two separable parts, one of which may be regarded as the cover to the other, as, for example, the screw cover 6 shown in the form of Figs. 1%, which closes a lateral opening into the interior chamber of sufficientdiameter to allow the nut and its securing means to be easily inserted.

In the form shown in Fig. 5,the main part-11 of the separable closed casing therein shown, has suitable attachment provisions 12, as above described, but its interior chamber opens at the end instead of at the side, being closed by the cover part 13, which, in this case, carries the hearing or support for the longitudinally movable rod 3. The cover part 13 screws into the other, and its interior face within the chamber constitutes the abutment for the nut 5, as will be plain from the drawing. In its operation this device is manifestly similar to the form first above described.

In the form illustrated by Figs. '6-9 inclusive, the frame or casing 14 has the attachment means 2, the tubular bearing 8 for the threaded rod 3 and the opposite interior casing abutments 7 and 7 as above described, but the removable or cover part of this casing is in the form of a slide marked 15 which covers. and uncovers an opening in the side wall of the casing, suitable for the introduction of the nut 5 and the linch pin 10. The nut in this form is an ordinary hexagon nut and the body of the casing is correspondingly shaped, in cross section, for producing the non-rotatory engagement therewith above referred to. The opening in the casing is located near to the end of the interior chamber so that the nut cannot reach a position in registry with it, after the linch pin has been inserted, which renders the use of the cover part 15 quite unnecessary except in so far as it is preferred for the protection it afalso to project somewhat beyond the shoulder 16 of the casing, so that a linch pin 17 or equivalent locking device can be applied to its overhanging end to fasten the cover in place, as clearly shown in Figs. 7 and 9. The mannerof forming the sliding connection between the casing and the cover will be plain from the drawings.

.Figs. 10 and 11 illustrate with the same reference numerals, the form of the invention last above described combined with means, substituted for the connection jaw 2, which permits the adjustment of the length of the operating line. The said means comprises a tubular boss 18 formed on the end of the casing, and screw-thread- 1 ed in its interior to receive the threaded end of the connection rod 19 which may be a switch rod or any other member of the op erating pipe line. A look nut 20 may be used for tightening the rod in. its adjusted position within the boss. By rotating the rod 19 relatively to the casing the operating line may be properly adjusted to the distance between the operated and operating elements in obvious manner.

Combined with any of the above forms the invention includes a locking means functioned to hold the threaded rod 3 against rotating within the casing, during the normal use of the device, although permitting the free reciprocation thereof as above described. This means consists of a key shown at 21 in Figs. 10 and 11 adapted to be non rotatably connected to the end of the rod and having, in whole or in part, an angular shape corresponding to the shape of the lost motion chamber so as to be non-rotatable therein. This key may be used in place of the linch pin 10, being similarly held in a cross-hole in the end of that rod, and confined in place by the cover. When used with the form of Figs. 10 and 11 it serves to prevent rotation of the casing relatively to both of the threaded connection rods and hence insures the permanence of both adl justments.
