Cl'J'Sl-IIIOISIINGrl DEVICE FOR LOOSE RAILS OF SPRING-FROGS.

Specification of Letters Patent.

Patented Aug'. 10, 1909.

Application filed May 22, 1909. Serial No. 497,503.

To all'whcm it may concern:

Be it known that I, GnonenW. Wnrrn- MAN, a citizen ofthe United States, residing in the city and countyof Philadelphia, State of Pennsylvania, have invented a new and useful Cushioning Device for Loose VRails of Spring-Frogs, of which the following is a specification,

One of the main objects of my present invention is to devise a novel construction of a spring box by the employment of which the vertical movement loose rail are reduced to a minimum when a train is passing thereover, thereby eliminating iny a great' measure the rattle and noise which occur in the construction of spring boxes usually employed. s

Another object of my invention is to produce ar device whichwill resist the tendency of the loose rail to lift whenthe loose side of the frog is run through.

With the above objects in view my invention consists of a novel :construction of a spring box, wherein a` downward and lateral pressure is exerted againstvthe loose rail.

It further consists of a novel construction of a cushioning device `for loose rails, wherein a spring actuated plunger is mounted I at an angle to the base of the loose rail, said plunser having its eentleet rertien edepted. tO coact with thefiller blocl; on the loose rail in such a manner that a downward vand lateral pressure will be imparted thereto.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose :of illustrating my inventien I here ehevn in the .eeeemnenyng drawings one yform thereof, since ,this embodiment will give ,in practice satisfactory and reliable results, althongh it is to be un-v dersteed that the variete nstrumeutelitiee of which my invention consists can be va. riously arranged and organizedand invention is not limited @to the exact n arrangement and Organization ef these instrumentalitiesashere setforth. l'

1 deslgnates a frog consisting of the fixed .rail 2, the rails 3 Vand 4 and a loose rail 5.

y6 designates anouterV filler block through rwhich passes Va suitable :fastening device such as'the bolt 7, the latter also passing through the intermediate filler block 8, the inner filler block 9 and the rails 2, 3 and 4, said bolt being provided with a suitable nut 10, in the usual manner. i

' 11 designates a base plate suitably xed in position and to which the rails 2, 3 and 4 are rigidlysecured by means of the fastening devices 12.- i

The loose rail 5 has secured 4thereto by means of a suitable fastening device such as, for example, the rivet 13, the filler block 14 and -also a block 15, the lower portion of which engages the base ange of the rail, it being bestunderstood by reference to Fig. 2 that the block 15 is provided with a suitable recess 16, which is shown in the drawings as being concave.

In'the present instance, for purposes of upwardly deflected, as is indicated at 17 and having secured to its under face an angular shaped block' 13, by means of rivets or equivaient fastening devices 19. The outer end of the base plate4 11 extends upwardly to form a flange l20 against which abuts the lower end of the spring box 21, it being seen that the iiange 20, if desired, may be slightly recessed as indicated at 22, in order that the lower portion of the spring lbox 21 may extend thereinto.

f 2,3 designates a dplunger mounted in the spring "box 21, sai, plunger having its forward'end reduced to a preferably blunt point order that ,the contact portion thereof Amay engage'with the re'cess`16 in the block ing `l`providd with the lugs"V 26,' through which vhe"bolts 27, the vlatter also passing throuph vlugs 28, ycarried by the spring the box 21, said bolts 27 being provided with suitable nuts 29, whereby the closure 25 is suitably secured with respect to the spring box.

30 designates a spring, one end of which abuts against the plunger 23, the other end thereof abutting against the closure 25.

31 designates a second spring, which in the present instance, is shown as being stronger than the spring 30, one end of said spring 31 abutting against the plunger 23, the other end thereof abutting against the closure 25, it being understood that the tendency of the spring 30 is to maintain the plunger 23 in its forward position, while the tendency of the spring 31 is to resist the rearward movement of the plunger toward the left of the position seen in Fig. 2. The spring box 2l is provided with flanges 32 through which pass the bolts 33, said bolts also passing through the base plate 11 and p ate 18, and being provided with suitable nuts 34, whereby the outward portion of the box 2l is rigidly secured in position.

35 designates suitable fastening devices, whereby the base plate 1l is rigidly secured in position.

It will now be a parent to those skilled. in this art that the pfiinger 23 exerts a yielding pressure against the loose rail 5 at an angl to the base thereof, or in other words, it exerts ,a downward and a lateral pressure against the loose rail 5, so that the vertical lift of the rail 5, when run over, is reduced to a minimum and the rattle and noise when the rail is run over are practically eliminated and a suitable resistance to the lifting action of the rail is also loose side of the frog is run through, as will be readily apparent to those skilled in the art, to which this invention appertains.

In the operation, when the frog is run provided when the i through, the outward movement of the loose `rail 5 is suitably cushioned by the tension of the spring 3l against the plunger 23 and owing to the angle at which the plunger 23 exerts its pressure on the block 15, the tendency of the loose rail 5 to lift is practically eliminated, since the conical end of the plunger 23 engages the recess 16 in the block l5 in such a manner that while the loose rail 5 is permitted to move laterally on the base plate ll, its vertical movement is positively prevented in a very reliable and advantageous manner.

In so far as I am aware I am the first in the art to employ in a device of this character, a spring actuated plunger which exerts a yielding pressure against the loose rail of a spring frog at an angle tothe base of the frog, and while in the present instance I have shown the base plate ll as being deflected in order to elevate the rearward it is to be understood that this is only one means of accomplishing the purpose and is end ofthe spring box,

only shown in this manner to illustrate a practical form of my invention, it being only essential that the spring box be rigidly supported so that the spring actuated plunger carried thereby will exert a lateral and a downward pressure against the loose rail of the frog.

It is of course to be understood that any suitable type or construction of filler block, against which the spring actuated plunger abuts, may be employed with the loose rail, although, if desired, in some cases such filler bleek may be dispensed with and the plunger abut directly against the loose rail.

It will now be apparent that I have devised a novel and usefu construction of a cushioning device for loose rails which embodies the features of advantage enumerated as desirable in the foregoing and while I have in the present instance shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
