Specification of Letters Patent.

Patented Dee. 4, 1906.

Application filed October 5, 1906. Serial No. 337,581.

To @ZZ whom t may concern:

Be it known that I, ViLLiAM CLARK IVOOD, a citizen of the United States of America, and a resident of Hoboken, in the State of New Jersey, have invented a new and useful Improvement in Tongue-Switclies, of which the following is a specification.

This invention is primarily additional to the improvement in tongue switches described and claimed in my specification forining part of United States Letters Patent No. 790,335, dated May 23, 1905, but may be enibodied in part in tongue-switclies of other constructions. y

The leading objects common to the present improvement and that patented by said Letters Patent No. 790,335 are to construct an antistraddling or antikieking tongue-switch in which the tongue is held to either side of its travel by spring-pressure in an effective way and to construct suoli switches without the customary heel-pin and with an effective provision whereby the tongue is kept firmly down on its bed and its heel end is effectively prevented from being driven down into the bed or iioor of the switch. Such driving or grinding down of the heel of the tongue in tongue-switches as heretofore constructed is owing to the fact that there is a slight movement of the tongue every time the car passes over it, the tendency of the tongue being to go with the Vtravel the same as the rails, and the only thing to prevent such travel or creeping aheadH has been the heel-pin, which soon wears, so as to leave the tongue loose.

In the improved switches the heel end of the tongue is pivoted within an undercut socket and is pressed into this socket by the antistraddling spring. Owing to such construction, the improvedswitches are equally well adapted for use either as trailingswitches or as head-on or facing switches.

The distinguishing objects of the present invention are to simplify the antistraddling feature of the improved switches and to dispense with one or more pivotal joints in the construction of such switches.

This invention consists in certain novel combinations of parts hereinafter described and claimed.

A sheet of drawings accompanies this speciication as part thereof.

Figure l is a plan view of an improved tongue-switch, illustrating this invention, the spring-containing box being shown in section. Fig. 2 represents a longitudinal section in the plane of the tongue. Figs. 3 and 4 are respectively an elevation and a top view of the tongue detached, and Fig. 5 is a fragmentary sectional plan view illustrating a modification.

Like reference characters refer to like parts in all the figures.

In common with said patented switch the body a of the improved switch and tliecon nections of said body with the adjoining rails l, 2, and 3 may be of any known or improved description. Within the switch-body a and preferably and conveniently in part within a steel center b the movable point of tongue c is arranged, as shown in Figs. l and 2 and Fig. 5, so as to be movable horizontally in customary manner. This tongue also may be of any known or improved construction apart from the features hereinafter specified, and included in the appended claims, respectively.

For pivoting the tongue c its heel end is preferably constructed with a peculiarlyeveled knuckle 4, fitted to an undercut pivotal recess 5 in the adjoining edge of a steel heel-cap d, which is fastened in place by vertical bolts or rivets e, Fig. l.

The improved means for holding the tongue c in its respective positions of rest and for holding it down upon its seat within the switch-body a and pressing it endwise into said pivotal recess 5 include a horizontallymovable shifting bar f or j" substantially at right angles to the tongue c and interacting therewith, a spring device g, which may be of known construction, hereinafter termed a spring arranged horizontally and substantially parallel with said tongue and interacting with said bar f or f and a locking device 71 or h, including a V-sliaped detent 6 or 6, preferably in the form of a projection, the inclines of which are arranged sidewise with reference to the tongue, said bar f or f being provided with a matching pair of inclines 7 or 7, which are preferably and conveniently formed by a matching projection interacting with said detent 6 or 6.

The customary spring-containing box 'i is rigidly attached to the switch-body a at one IOO locking device 7L is formed on the bottornwofV the tongue c as a substitute for the shifting pin oi: said patented switch, and said interacting inclines 7 are carried by the tongue end of the shifting bar and said bar is supported against endwise movement by a pivotal abutment 10 at its outer end within said spring-containing boX i.

In the modiiication illustrated by Fig. 5 the locking device h/ is arranged Within the spring-inclosing boX i. Said V-shaped detent 6" is formed on a steel piece rigidly bolted in place within the boX, and the matching inclines 7 are carried by the outer end of the shifting barf, the inner end of the shifting j bar being pivotally attached to the tongue c by a shifting' pin 1l on the bottom of the tongue and a notch l2 in that edge of the shifting bar which is toward the heel end of the tongue.

A tensile spring may obviously be substituted for the compression-spring shown in both ofthe above-described arrangements, and other like modifications will suggest themselves to those skilled in the art.

Having thus described said improvement, I claim as my invention and desire to patent under this specification- 1. The combination, substantially as hereinbefore specified, of a switch-tongue having the customary horizontal travel from one position of rest to another, and anantistraddling device including a horizontally-movablev shifting bar substantially at right angles to said tongue interacting therewith, a horizontally-arranged spring substantially parallel with said tongue interacting with said bar; and a locking device including a V- shaped detent the inclines of which are ar- -ranged sidewise with yreference to said tongue, said bar being provided with a matching pair of inclines interacting with those of said detent.

2. The combination, substantially as hereinb'e'fore specified, of a switch-tongue having an undercut pivotal bearing at its heel end and having the customary horizontal travel from one position of rest to another, and an antistraddling device including a horizontally-movable shifting bar substantially at right angles to said tongue interacting therewith, a horizontally-arranged spring substantially parallel with said tongue interacting with said bar and pressing said heel end cluding a V-shaped detent the inclines of which` are arranged sidewise with reference to said tongue, said bar being provided with a matching pair of inclines interacting with those of said detent.

3. The combination, substantially as hereinbefore specified, of a switch-tongue having the customary horizontal travel from one p0- sition of rest to another, and an antistraddling device including a horizontally-movable shifting bar substantially at right angles to said tongue interacting therewith, a horizontally-arranged spring substantially parallel with said tongue interacting with said b ar, and a locking device including a V- shaped projection the inclines of which are arranged sidewise with reference to said tongue, said bar being provided with a matching projection interacting with said V-shaped projection.

Y
