'METALLIC ammonia-TIE.

Specication-of Lettera Patent.

Patented Dec. 1, ieee.

Application led July 17, 1941MB.v Serial No. 448,994.

' To oll'wlw/lngit 'may concern:

Be 1t known that I, ZYGMUNT Mnoozxow- SKI, a subject "of the Czar of Russia, residing,

at Chicago, in the county of Cook and State "i 5 of Illinois, have invented certain new and useful Improvements in Metallic Railroad- 'l.`ies, of which the following is a specificat1on.

This invention relates to metallic railroad 'lo ties and fastenings and has for its object to provide a metallic tie improved particularly Vwith respect to the means for fastening the :rail to the tie, the fastenin devices being suchthat the rail maybe rea ily attached or detached, without the use of spikes,t bolts,

screws and the like.

The invention embodies a channel metal "tie,` having lips struck up therefrom, and a chair-or plate on which the rail rests, said .20 plate-being formed in-,two sections which are locked together and which are fastened to the tie in such manner that they cannot become unintentionally released.

The construction ofthe device will be rgb more clearly evident from the following detelling, one rai scription and the accompanying drawings in ,iwhich- Figure 1 is a plan view ,of the tie and fasbeing shown removed and '30 Vthe other being shownin place; Fig. 2 is a [side elevation of metio; Fig. 3 is a longitudinal vertical section thereof.

l The tie 6 preferably consists of a chanfneled steel bar` thelanges of which are directed downwardly Vwhen the tie is set in` position;A The top of `the tie 4has lips 7 struck up therefrom,lthe distance apart of these lips being' somewhat greater than the width of the rail base,lthe rail being shown 4,0 at 8. The lips 7 for the res ective rails are curved inwardly or towar each other to engage over vthe chair or fastening plate. This chair or late consists of two sections 9 which are similar in all respects except' thatthey are made rights and lefts. Each section of the plate extends across the tie, and they meet at their inner side edges with a butt or shoulder joint indicated at 10, whereby movement of the plates with respect to each other is prevented in one direc- '55 of proper width to lit snugly within or be.

tion. At the outer edge of each section of the plates is a ange 11 curved up and over to engage over the rail base, and the two sections, when placed together, form a plate 'tween the'lips 7. VAt one end each section has a tongue 12 'which is adapted to be bent or pounded down to engage beside the edge of the tie, as shown, and when these lips 4are so pounded down they act "to prevent movement of the sections in a direction opposite to that mentioned above. In other words, the shoulder at 10 locks the sections together one way, and the tongues prevent movement the other way. The plate formed of the two sections is thus held in place on the tie, the lips 7 acting to prevent lift of the plate. As stated, the curved iianges ll engage over the edges of the rail base, and so the railr is held in position.

To attach the fastening the two sections 9 are placed on the base of the rail beside the tie and are then slid along on the rail to position within or between the lips 7. The tongues 1Q are then pounded down, and the fastening plates are thus held as set. To

.remove the plates and detach the rail it is only necessary to knock up the tongues l2 after which the plates 9 can be hammered alon until they are disengaged from the lips when the fastening plates can be removed from the rail base and the rail can be detached from the tie. The sections of the rail plate are made of metal sulicientlyv malleable to enable the tongues 12 to be pounded down or up without fracture. Said plates support the rail which rests thereon, instead of directly on the tie. There are no loose parts such as bolts or screws, and no tools except a hammer arc required to place or remove a set of fastening-s. The tie itself can be cheaply constructed since no special work is necessary, except Vto strike up the lips 7, and inasmuch as these lips are integral with the tie. there is little or no possibility of the fastenings becoming loose accidentally.

I claim:

l. The combination of a tie having lips projecting upwardly therefrom, and a tie plate held on the tie by said lips, said plate being formed in two sections, and having means at its. side edges to engage the rail base, and means to prevent separation of the sections.

2. A tie plate comprising two` sections which meet on a line transverse of the tie, with a shouldered joint, each section having a tongue at the end adapted to be bent down over the side edge of the tie, and a curved flange at the outer edge=adapted to engage over the margin of the base of the rail, and means to fasten the rail plate to the tie.

3. The combination 'of a metallic tie having opposite lips struck up from the top thereof, a tie plate fitting closely between said lips which overhang the edges of the plate und retain the same on the tie, saidplate being made in two sections which meet under the rail, and having n curved unge at each outer edge thereof which engages over the miugin of the rail base, and means to prevent lateral movement of the tie plate 10 sections with respect to the rail.

In testimony whereof, I affix my slgneture in presence of two Witnesses.
