CATTLE-GUARD.

SPECIFICATION forming part of Letters Patent No. 500,730, dated July 4, 1893.

Application filed December 7,1892. Serial No. 454,353. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN WoLHAUP- TER, a subject of the Queen of Great Britain, residing at Morgan Park, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Cattle-Guards; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object the produc-- tion of a rail-way cattle guard of that class in which a series of guard bars made of plates of metal, are placed in an inclined position, and parallel with each other.

This invention relates first to the form of the upper edge of the guard bars, and secondly, to the manner of securing the guard bars to the cross bars.

In the drawings: Figure l. is a plan view of my guard. Fig. 2. is a horizontal section; Fig. 3. a view looking at the construction shown in Fig. 1. from the direction of the arrow with the rail removed; Fig. 4.. a detail of the cross bar; Figs. 5. and 6. details showing two ways of securing the guard bar to the cross bar. Figs. 7. 8. 9. and 10. show different ways of shaping the upper edge of the guard bar.

In carrying out the invention A represents the track rails; B the guard bars of my guard.

'O are the cross bars, preferably shaped in cross section as shown in Figs. 5. and 6., although instead of a cross shape, they might be angle or T shape. The upwardly projecting flange is provided with inclined slots 0. The guard bars are set in these inclined slots and are held to the cross bars in the following manner:-In the lower edge of the guard bar the metal is punched out, or up-set, as at I), thus providing a shoulder which bears against the upwardly projecting flange c of the cross bar. The metal of the lower edge of the guard bar on the opposite side of the flange 0 may either be up-set as at b Fig. 6, and bent down underneath the flange c of the cross bar, or an orifice b Fig. 5. may be punched in the lower edge and a channel iron or key D be extended through to engage the lower edge of the guard bar B with the cross bar.

It will be observed that in Fig. 1 the upper edges of the guard bars are scalloped as at B, the scallops of one bar being out of alignment with the scallops ot' the next adjacent bar. It is obvious that the upper edge of each guard bar may have plain scallops, as in Fig. 1., or the projections may be provided with V shaped recesses E Fig. 7, and the depressions provided with teeth F Fig.7, or the depressions shown may be provided with. teeth Fig. 8, or the scallops or projections may be angular in shape as shown at G Fig. 9, and they may, or may not be provided with recesses H and teeth J Fig. 10. These various forms obviously come within the scope of my invention which lies essentially in the provision of inclined guard bars, having a series of enlargements, or scallops, which when placed in the inclined position indicated will have one of the enlargements or projections overlapping a depression or recess in the next adjacent bar. With this form of construction an exceedingly effective guard is produced, while at the same time the cost is materially lessened, from the fact that a single sheet of metal, by being cut longitudinally through the middle by dies, or otherwise can be made into two of the guard bars.

I am aware that cattle guards have heretofore been constructed in which vertical bars were provided with scallops that alternated with each other in transverse alignment. I am also aware that inclined bars have been provided with saw teeth, and these of course I do not claim, but

What I claim is- 1. In a cattle guard the combination of a series of guard bars extending substantially parallel with, and adjacent to each other,said guard bars being in an inclined position, and the upper edge provided with a series of seallops, a projection on one bar over-lapping and being in transverse alignment with a depression on the next adjacent bar, substantially as described.

2. In a cattle guard the combination of a series of guard bars extending substantially parallel with each other, the upper edge of the bar beingprovided with enlargements or scallops and the depression between each scallop being provided with a sharp tooth, substantially as described.

3. In a cattle guard the combination of a series of guard bars extending substantiallyparallel with, and adjacent to each other, said guard bars being in an inclined position, and the upper edge provided with aseries of seallops, a projection on one bar over-lapping and being in transverse alignment with a depression on the next adjacent bar, the depression between each projection or scallop being provided with a sharp tooth, substantially as described.

4. In a cattle guard the combination of a series of guard bars extending substantially parallel With, and adjacent to each other, said guard bars being in an inclined position, and the upper edge provided with a series of seallops, a projection on one bar over-lappin g and being in transverse alignment with a depression on the next adjacent bar, each projection or scallop being provided with a V shaped recess and each depression between the seallops being provided with a sharp tooth, substantially as described.

5. In a cattle guard the combination of the guard bars and cross bars, the latter having an upwardly projecting flange provided with inclined slots in which the guard bars are placed, and one or more projections on the guard bar formed by up-setting the metal to prevent longitudinal displacement of the guard bars, substantially as described.

6. In a cattle guard the combination of a series of guard bars and cross bars, the latter provided with an upwardly projecting flange having slots in which the guard bars are placed, and with a horizontally projecting flange, the lower edge of the guard bars being provided with an orifice or slot and a bar or key having a flange to engage in the slot in the guard bar and to engage also the horizontal flange of the cross bar, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

BENJAMIN WOLHAUPTER.
