Y To all whom it may concern.'

which ,the fol-lowing is a ull, clear, 'and exact description. f

My invention relates to a khangeror grip to be employed in street cars, railway cars, etc., in lieu of the hanger straps, and particularly the invention relates to Ian eXten-` sible hanger grip adjustable as to its length in the space to suit the reach of persons of v,different stature.

'The invention has for its Iobject to provide a telesceping hanger grip and novel means to permitoi' the extension movement when desired. i

vReference is to be had to the accompanying drawings 'forming a part of this specification in which Isimilar reference characters indicate corresponding parts in `*all the views, it being understood that the drawings are `merely illustrative of .one example of the invention.

Figure 1 is aside elevation of a hanger grip embodying my invention, the usual car rod or rail being in cross section lon the ,af-.lille l-L Fig. 2.

Fig. 2 is a longitudinal vertical section on the line 2 2, Fig. 1; y

Fig. 3 is a horizontal section on the line 3-3, Fig. 2. ln carrying out my invention in practice, suitable suspension means are provided to suspend the device from the usual rail A of a car, there being shown a loop or strapl() in the present instance. The suspension hanger 10 suspends telescoping elements, there being a relatively fixed casing 11 and an element 12 telescoping in the casing 11 and preferably made tubular for lightness. @n the lower end of the element 12, outside of the casing 11, is a hand-hold or grip 13, here shown in the form of a U-shaped loop or strap integral with said element 12 and presenting depending members at two sides joined by a bent transverse portion 1/1 at the bottom.

A spring 15 is coiled about the element 12 between said element and the casing 11, the spring bearing at its lower end against an inturned flange 16 on the casing 11 and at its upper end against an` annular flange 'or collar 17 on the elements c 12 below .the top of the casing k11. The spring 15 tends to maintain the element .12 in theretracted position in the casing 11 and the inward :movement or' said element is limited by a stop flange 1S at the upper end of .the :handle 18, a washer 19 preferably being interposed between said flange 18 and a flange 16 on the casing 11.

I provide coacting members on the` casing 11 and on the telescoping member 12 to resist lextensible movement oi' the latter or toV permitsaid `extensible ,movement wheny de* sired .for which purpose in the `illustrated example latches'20 are pivoted on the ele ment 12 at the upper end thereof, preferably `diametrically opposite, by horizontal, pivots 21 and are under the pressure of springs 22 :here shown as formed from a single element secured to the top 23 ot the element 12 and adapted to `project the said latches laterally `outward through slots or openings 24- formed in said element 12. ln the laterally lprojecting positions yof the latches 20 they lie above lined arcuate stops 25 on the casing 11 at the interior, so that by the engagement of .the latches with the stops, outward movement of the element 12 is resisted and a person therefore holding onto the hand-hold 13 will be aiorded firm support with the element 12 in the raised or retracted position which is suited to a person of average height. To eect an extension of the hanger, the telescoping element 12 may be turned through an angle to dispose the latches 20 out ol alinement with the stops 25, there being arcuate openings between said stops at diametrically opposite sides of the casing 11 to permit the latches 2O to clear the stops in extending the handle by a downward pull on the hand-hold 13 against the tension of the spring 15, thereby placing the said spring under tension and positioning the latches 20 below the stops 25. The spring 15 thereby tends to return the element 12 to the retracted position when the hand-hold 13 is released and the strength of said spring 15 is superior to that of the springs 22, whereby should the latches 20 be in line with the stops 25 in the upward movement oi the element 12, the latches will be forced inwardly by Vengagement o their outer edges with the opposed edges of the said stops. 'lhe said outer edges of the latches it will be observed Vare'beveled` to causethe inward movement of the latches in contacting with the stops 25 under the action of the spring-'15.

I wishto state in conclusion that although Vthe illustrated example constitutes a practical embodiment of my invention, I do not ylimit kmyself strictly'to the mechanical de- Van elongated element telescoping in the casing, a hand-hold on said element below the casing', a spring` within the casing and acting on the said element tending to maintain the same inthe retracted position, a stop on the said casing at the interior, below the top, a latch pivotedk on the said telescoping element adjacent to the upper end to normally lie above the stop, and a lspring acting on said latch and tending to maintain the same in the path 0f the stop, the said telescoping element being adapted to be turned through an anglefto aline' the latch with the stop or to position it out lof line with the stop to clear the latter, and the first mentioned spring heing of a strength to overcome the pressure of the latch spring and carry the latch past the stop in the retracting movementor' the telescoping element.

2. An extensible grip for cars, including suspension means, elements suspended from Copies of this patent may be obtained -below the casino the said means, one of said elements telccoping the other and provided with a handhold below the otherl element, spring means tending to maintain the telescopingelement in retracted position, and coacting means on the respective elements adapted for coengagement to resist relative longitudinal movement thereof, the said elements being relatively turnable through an angle to disengage said coacting members and permit relative longitudinal movement of said elements to eiect extension of the grip.

3. An extensible grip for cars, including extension means, a casing thereon, a tubular element telescoping in the casing, a spring normally tending to maintain the element in retracted position, fixed stops on the casing at the interior, the said element having slots disposed above the stops when the telescoping element is in retracted position, latches pivoted to said element and lying in thc said slots, spring means tending to maintain the latches projecting beyond the slots to be engaged with the stops, the outer edges of the said latches being beveled, and a U- shaped hand-hold on the telescoping` eleniient g, said element being turnable in the casing 'to bring` the latches into or out of registerl with the stops for an outward movement of the said element, and the Vtirst mentioned spring being adapted to overcome the pressure ot' the spring means associated with the latches upon the beveled edges of the latches contacting with the stops and upon an inward movement of the telescoping element.
