adjustably securing said heads on grooved sleeves present on the ends of brake-beams.

The main object of the present inventionis to provide a very durable brake-head lacking complexity and. capable of, being adinstably secured to the beam by very durable and inexpensive means adapted to the rgroovc in the sleeve on which the brakehead is mounted.

The invention will I be fully understoed from the detailed description hereinafter presented, reference being had to the accompanying, drawings, in. which Figure l isa side elevation of a portion of one end of a brake-beam having thereon: a grooved sleeve, brake-head and securlng means embodying ,myinvention; Fig.2 is a central vertical section through the same on the dotted line 2 2 of Fig. 1;ljig. 3 is;

, a top view of the same, and Fig. 4 is a face view, Fig. 5 an edge view and F 1g. 6 a top view of a key employed in accordance with: my inventionfor securing the brake-head upon the beam.

In the drawings, 10 designates the brake-; head as a whole, and this head, with the eraception of the features embracing my invention may be of customary or any suitable form and construction. The brakebeam is numbered 11 and the sleeve thereon 12, said sleeve being formed with a circumferential groove 14- extending around or partly around the same, as usual, and re ceiving the head 10 in a manner well understood.

, a transverse exit slot 17 for ahey or strip 18 whose middle portion enters the groeve 14 and firmly bears against the sleeve 12 and effects the securing of thehead onthe beam. The key 18 will preferably be inthe form of a flat strip of strong spring metal,

as represented in Figs. 4, 5 and 6, and will have its upper end flanged outwardly, as

at 19, the middle portion of the flange being less in width and greater in length than the body of the flange and creating a tongue 20. Tlie,back of the head 1.0 adjacent to the entrance slot 16 is formed with averticalreeess 2lwhich is about the a width of and freely receives the tongue 20, as may be understood on reference to Fig. 1, and said head at,the oppositesides of said recess 21 15 formed with interior transverse recesses 22 adapted to receive the end port-ions of .the flangelQ when the key 18 is in position lockingthe head 10 to the beam. The engagement of-the ends of the flange 19 with therecesses 22 serves to lock the key 18in position and to guard against any acciden- ,tal displacement of the key. The entrance slot 16 is, however, of such proportion fore and-aft that the upper end of the key 18 may bdfOl'CQtl inwardly to free the flange 19, from therecesses 22 and permit of the removal of said key, when desired.

The

tongue 20 and flange 19 form a head for the [key 18 and not only aid in the proper securing of the key in positionbutfacilitate the application of the key to the head 10 and its removal therefrom.

The head lO is an integral casting and lacks hinged parls, adjusting bolts and. nuts and thehhe, and in consequence is of very durable character and simple of construction. The key 18 13 an integral strip of spring metal and, when in position bears at its ends against the walls of the entrance and exit slots or

openings

16, 17, respect1vely, and at its middle portion lies within the groove of the sleeve 12 and bears strongly against the rear side of said sleeve,

with the result that the head'is bound very firmly against the sleeve and eiliciently se cured thereto. In securing the head on the sleeve, the key or strip 18 is applied to the entrance opening 16 and then forced or driven downwardly until the lower end thereof takes its bearing against the wall of the lower opening 17. The flange 19 is, finally, caused to engage the recesses 2:2 for the purpose of relcasably springdatching or 1 locking the key or strip 1 to the head and against accidental displacement. The entrance and exit slots or

openings

16, 17 may be substantially one below the other but are inwardly of the vertical plane of the rear or back surface of the groove 14 of the sleeve 12, so that when the normally flat key or spring strip 18 is driven downwardly through the inlet opening 16 it will become flexed against said'sleeve on the passage of, its lower portion to the exit slot or opening 17, as shown in Fig. 2.

The slot 17 is shown as open at its lower end with the key or strip 18 protruding theret-hrough, and this is the preferred construction for several reasons, but the main essential is that the lower end of the key or strip 18 have a substantial bearing against the head regardless of the exposure of its extremity. i

I do not confine my invention to details of construction further than may be rendered necessary by my claims, the essential consideration being that the independent strip or key 18 when driven home shall firmly bear at its upper and lower ends against the head and at an intermediate portion against the part to which the head is to be secured,this part preferably being a sleeve on the end of the beam on which the tubular part of the head is fitted and which has a groove or reduced portion to receive such intermediate part of the key or strip.

What I claim as my invention and desire to secure by Letters Patent, is:

1. In a brake-beam, the combination with an adjustable brake-head having an integral closed back portion, a part of the beam on which said head is mounted, and a flexible spring key for securing said head on said part, said back portion of the head having upper and lower openings for said key inwardly from the vertical plane of the rear or back surface of said part of the beam on which the head is mounted, and said key being normally substantially straight so as to become flexed against said part when driven through the upper to the lower of said openings.

2. In a brake-beam, the combination with an adjustable brake-head having an integral closed back port-ion, a part of the beam on which said head is mounted, a flexible spring key for securing said head on said part, and means for detachably securing one end of said spring key, said back portion of the head having upper and lower openings for said key inwardly from the vertical plane of the rear or back surface of said part of the beam on which the head is mounted, and said key being normally substantially straight so as to become flexed against said part when driven through the upper to the lower of said openings.

3. In a brake-beam, the combination with an adjustable brake-head having an integral closed back portion, a grooved sleeve on the end of the beam on which said head is mounted, and a flexible spring key for se curing said head on said sleeve and entering the groove therein, said back portion of the head having upper and lower openings for said keyinwardly from the vertical plane of the rear or back surface of the groove in said sleeve, and said key being normally substantially straight so as to become flexed against said surface of said groove when driven through the upper to the lower of said openings.

4. In a brake-beam, the combination with an adjustable brake-head having an integral closed back portion, a grooved sleeve on the end of the beam on which said head is mounted, a flexible spring key for securing said head on said sleeve and entering the groove therein, and means for detachably securing one end of said spring key, said back portion of the head having upper and lower openings for said key inwardly from the vertical plane of the rear or back surface of the groove in said sleeve, and said key being normally substantially straight so as to become flexed against said surface of said groove when driven through the upper to the lower of said openings.

5. In a brake-beam, the combination with an adjustable brake-head, a part of the beam on which said head is mounted, and an independent flexed spring key hearing at its ends against the head and at an intermediate portion against said part, said head and one end of said key respectively having an interengaging recess and a flange releasably latching the key to the head.

6. In a brake-beam, the combination with an adjustable brake-head, a grooved sleeve on the end of the beam and on which said head is mounted, and an independent key bearing at its ends against the head and at an intermediate portion against said sleeve within the groove thereof, said head and one end of said key respectively having an intel-engaging recess and a flange releasably latching the key to the head.

7 In a brake-beam, the combination with a. brake-head having at upper and lower sides of its back open transverse slots, a part of the beam on which said head is mounted, and an independent key in said slots and bearing at its ends against the outer walls thereof and at an intermediate portion against said part.
