Application led July 29, 1912.

T0 all 'whom it may concern Be it known that we, JoHiv ,l. Monsn and WILLIAM B. MALLETTE, citizens of the v1United States, residing at St. Louis, State pensive vcharacter and one that is very etlicient for the purpose, but also one that may be installed quickly and conveniently and be readily repaired at comparatively small cost, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts, Figure 1 is a top or plan view showing a cattle guard embodying oui` said improvement as in position ina railway track, a portion of the saine being broken away in order to illustrate the guard on a larger scale. Fig. 2 a longitudinal section through the same on the dotted line 2-2 in Fig. 1, Fig. 3 a cross section on the dotted line 3 3 in Fig. 1, Fig. Il a longitudinal section showing a modified construction, Fig. 5 a perspective view of one of the end bars separately, Fig. 6 a similar View of one of the intermediate bars, Fig. 7, a view similar to Fig. 5 showing a slightly modified form, Fig. 8 a detail perspective view showing other modications in the construction, Figs.

ing shown with side ianges 15, inclined inwardly from the bottom of said pockets toward their tops, and with end iianges 16. The intermediate bars or castings 11 are preferably formed as best shown in Fig. 6, having pockets to receive the inner ends of bars 12 and open at both ends and with side flanges 17 inclined inwardly from the bottom to the top. The form shown in Fig. 7 is adapted for use either at the ends or intermediate thereof in the structure, the walls of the pockets being of suflicient thickness so that all of said pockets may be formed with contracted upper ends, and not with oppositely flared channels between them, as shown in Fig. 5. Ill/hen suoli bar is used at an intermediate point `in the structure the ends of the guard bars of the adjacent sections will be set therein in staggered form so that their ends will abut the end flanges and be held from longitudinal movement, as will be readily understood.

The longitudinal guard bars 12 are of the form best shown in Fig. 2 and in cross section iii Fig. 3, consisting of inverted V- sliaped steel bars with their ends inserted in the pockets ll in the end bars 12 and intermediate ends inserted in the pockets in the intermediate bars 11, as shown in Figs. 1 and 2. It will be understood, of course, that the particular three-cornered form of bar shown is not essential, as other forms, the ends of which are capable of being retained by the pockets without fastening devices may be used without departing from our invention. Other forms are illustrated in Figs. 9 to 12.

The cattle guard, as illustrated in Fig. 1, is made in four sections, each end comprising two of the bars 10, while two of the bars 11 are used at an intermediate point, or, as shown, at the center of the guard. The longitudinal joint between the sections is as on the dotted line 2-2 in Fig. 1. rlhe bars 12 extend Yonly half the length of the entire guard. Each bar is curved upwardly between its ends, as best shown in Fig. 2. By reason of this form the guard as a whole is given a wavy, corrugated, or irregular surface, making it more readily noticeable and forbidding in appearance, and serving to deter cattle from venturing to cross the same. By reason of forming the end bars with the pockets with closed ends the loiigitudinal bars'12 may be placed in position without other fastenings than the fastenings Y afforded by the tapered flanges of the pockets in the bars 10 and 11 respectively. Said bars are secured by bolts, lag screws, or spikes, extending vertically through the plates into the ties and if additional security is desired flanges 18 (Fig. 8) may be cast on the end bars adapted to extend down against the face of the ties and be secured by bolts or spikes 19 extending horizontally through perforations therein. In some cases the horizontal bolts or spikes may be preferred and used kin lieu of the vertical lspikes as the sole securing means.

In Fig. l we have indicated a cattle yguard composed of a single length of longitudinal bars 12 supported wholly by the end plates 10. The bars 12, however, are of substantially the same general forln as those shown in the` principal views, being preferably of metal stamped/of the form shown, or other equivalent form.-

v In Figs. 7 and 8 we have illustrated another modiiication intended to employ solid wooden bars 20 in lieu of the hollow metal bars 12, said bars, however, are supported at their ends in the same character of pockets `with closed outer ends as in the principal views.

nFigs. 9, 10, and 11, we have shown a modification by which the invention is adapted for the use of round bars 26 in lieu of the angular bars 12, should it, for any reason, be found desirable to do so. Said round bars 26 are mounted in angular blocks 27, which blocks are adapted to fit in the pockets in the castings 10 and 11 in the same manner as before described for the ends of the angular bars 12. The upper edges of ysaid blocks 27 are preferably tapered, as shown in said figures, in order to guard against any yof the brake rigging on the cars, or other hanging parts, catching or engaging with the cattle guard as .the trains pass over it.

In Fig. 12 we have illustrated still another modification wherein triangular wooden bars 29are substituted for the form of wooden bars 20 shown. in Fig. 8. As will be seen said bars 29 may be formed by cutting a rrectangular barin two parts along a line substantially intersecting its diagonally opposite corners and economy Vthus secured in rlhe pocketsV in the casting for receiving said bars will be eorrespondingly modied to fit the shape of said bars, as illustrated in said Fig. 12. It may be found desirable, in addition to the spikes, lag screws, or other lsecuring means, to have projecting points formed on the under face of the castings 10 and 11 and in Fig. 12 we have illustrated two forms. of vsuch points, the point marked 30 being conical andthe point marked 31 angular.

rlhese and other modifications in details will be obvious to those familiar with the art. While we have shown various forms of securing means for attaching the castings t0 the ties it is obvious that other forms may be employed and we do not intend to limit ourselves to any specific form.

By this construction we provide a cattle guard which is not only very rigid in construction and eflicient and practical in use, but one wherein the guard bars are contained and supported in the transverse supporting bars without the use of bolts or spikes and may be readily removed and replaced, either in sections or individually, when one or more of the bars becomes injured or de- ,r stroyed.

Having thus fully described our said invention what we claim as new and desire to secure by Letters Patent is:

1. A cattle guard for railway tracks comprising longitudinal guard bars formed with sides contracted in width from their bases toward their tops, and transverse supporting bars secured to the ties and formed with pockets to receive the lower edges of said bars, the pockets of the end supporting bars being formed to correspond with the transverse formation of the ends of the longitudinal bars and with flanges extending across their outer ends at right angles with the sides of the longitudinal bars and against which said longitudinal bars are adapted to abut when the parts are assembled, whereby said longitudinal bars are reta-ined in said pockets against displacement both in an upward and in a longitudinal direction, substantially as set forth.

2. A cattle guard comprising metal guard bars formed contracted in width toward their tops and with upwardly curved portions between their ends, transverse bars for supporting said guard bars formed with pockets with tapered sides to receive and embrace their ends, said pockets having open tops through which the upper portions of said guard bars extend and with transverse flanges across their outer ends at right angles with the direction of said guard bars, whereby they are adapted to embrace and support said guard bars against longitudinal and transverse movement, substantially as set forth.

3. A cattle guard comprising longitudinally extending guard bars and transverse end and intermediate supporting bars, which supporting bars comprise solid base plates adapted to be secured to the ties and formed with integral pockets formed to receive and embrace the base portions of said guard bars, said pockets in the several supporting bars being open at their tops with the guard bars projecting into a plane above their tops, the pockets of the intermediate bars being` formed with open ends, and the pockets of the end bars with their outer ends provided with webs to engage the ends of the guard In witness whereof, we have hereunto set 10 hars, whereby a cattle guard is provided, the our hands and seals at St. Louis, Missouri, upper edges of the guard bars of which are this 26th day of July, A. D., nineteen huneXposed throughout their entire length and dred and twelve.
