T. F. McBVOY & 0. J. LEPPBRD. REVERSIBLE HARD CENTER FROG.
APPLICATION FILED MAY 5, 1913'.
Patented Sept. 9, 1913.

BIA PLANOORAPH C0.. WASHINGTON, D c- TIMOTHY llIoEVOY AND CHARLES J. LEPPERD, 0F POTTSTOWN, PENNSYLVANIA.
REVERSIBLE HARD-CENTER FROG.
To all whom it may concern:
Be it known that we, TIMOTHY F. Mo- EvoY and CHARLES J. Lnrrnnn, citizens of the United States, residing at Pottstown, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Reversible Hard-Center Frogs, of which the following is a specification.
()ur invention relates to improvements in reversible hard center frogs, the object of the invention being to provide a frog of this character which may be reversed in its entirety or any portion thereof reversed when worn.
A further object is to provide a hard center frog in which the hard center and the rails and parts connected therewith are constructed uniformly on opposite sides, so that any one or all of said parts may be reversed, and operate with equal efliciency in either position. 7
lVith these and other objects in view, the invention consists in certain novel features" of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.
In the accompanying drawings; Figure 1 is a plan view illustrating our improved frog. Fig. 2 is a view in section on an enlarged scale on the line 22 of Fig. 1. Fig. 3 is a similar view in section on an enlarged scale on the line 33 of Fig. 1. Fig. 4 is a similar view in section on an enlarged scale on the line t-t of Fig. 1. Fig. 5 is a similar view in section on an enlarged scale on the line 55 of Fig- 1. Fig. 6 is a similar view in section on an enlarged scale on the line 66 of Fig. 1. Fig. 7 is a similar view in section on an enlarged scale on the line 77 of Fig. 1.
1 represents the hard center of our improved frog which is secured between wing rails 2 projecting laterally in both-directions from the throat 3 of the frog. The center 1 at one end is provided with a relatively narrow longitudinal extension 4: clamped between the usual diverging track rails '5. These rails 5 and the extension 4: having registering recesses 6 in which relatively short plates 7 are secured by rivets 8.
Throughout the entire length of the frog, it is shaped alike on its upper and lower surfaces. That is to say, it is provided on top and bottom with integral rail support- Specification of Letters Patent.

ing points 9 and longitudinal diverging flange ways 10, with tread receiving -portions 11 forming the outer walls of said flange ways, and fitting within longitudinal recesses 12 in rails 2. A series of bolts 13 are projected through alined openings in the center 1 and rails 2 throughout the length of the body portion of the center, and these bolts are also projectedthrough bars 141 which are located against the outerfaces of the webs 15 of rails 2. Nuts 16 are screwed onto the bolts and are preferably held by any improved form of nut locking washer 17. Blocks 18 are located between the rails 5 and rails 2 at theeXtreme ends of the latter, and bolts 19 are projected through registering openings in rails 2, blocks 18, rails 5, and extension at, and are secured in place by nuts 20. i a 1 By reference particularly to the cross sections in Figs. 2 to 7 inclusive, it will be noted that the rails 2 are precisely alike at top and bottom throughout their ends.
These rails 2 are formed with heads 21 at top and bottom connected by a relatively thin web 15. The inner portions of the heads at top and bottom throughout a con siderable portion of the length of the frog, are formed wit-h the recesses 12 above re ferred to, to accommodate the tread portions 11 of the hard center 1. In other words, the shape of the faces of the rails at their point of contact with the center 1, conforms in shape to the shape of the center, and which shape gradually changes to form a firm and rigid interlocking contact as clearly illustrated in cross section.
As the hard center 1 and the rails 2, as well as the rails 5, are alike at top and bottom, they can be separably reversed or the frog as an entirety may be reversed and operate with equal efficiency. This is a distinct advantage because it frequently happens that only one of the parts becomes worn and this part may be reversed. If on the other hand, the entire frog is worn on its upper surface, it may be reserved, and in any event, the reversal of the several parts is a matter of judgment, and our improvements result in a'great saving to the railroad.
Various slight changes might be made in the general form and arrangement of parts described without departing from our invention, and hence we do not limit ourselves to the precise details set forth, but
consider ourselves at liberty to make such changes andalterations as fairly fall with.- in the spirit and scope of the appended claims.
Having thus described our invention, what we claim as new anddesire to secure by Letters Patent is:
l. A railroad frog comprising a hard center, shaped alike on its upper and lower faces, and rails secured tothe opposite sidesof the, center, said; railsthroughouta por tion'; Ofi their length recessed to=receivethe center. therein, substantially as described:
