To all whom it may concern:

Be it known that I, FRANKLIN E. ABBOTT, a citizen of the United States, residing at Buffalo, in the county of Erie and State of I New York, have invented new and useful Improvements in Tie Plates, of which thefollowing is a specification.

' My invention relates to tie-plates for railways characterized by a hook-shoulder arranged to engage with the rail-flange and consists in providing a second shoulder for engaging with the opposite rail flange.

I have heretofore invented an improvement in hook-shoulder tie-plates .which consists in forming and proportioning the hookshoulder so that its overhang shall be spaced a small distance from the upper surface of the rail flange, whereby the great security of the hook fastening is obtained without objectionable rigidity, and freedom of wave motion is permitted, with greatly reduced disturbance of the spikes and of the roadbed. Tie-plates provided with my peculiar 1 hook-shoulder and withan ordinary straight shoulder for engaging with the opposite rail flange have gone largely into use of late, particularly for difficult locations, where security in the rail fastenings is important and accident would have serious consequences. I believe such tie plate to be new and I have broadly claimed the same in my application which resulted in Patent No. 1,178,200, Apr. 4, 1916.

My present invention consists in a tie-' plate whereby much greater security is obtained, and this is accomplished by provid ing the tie-plate with two: hook-shoulders, one integral as before, and the other consisting of an integral shoulder without a hook and of a detachable hook, or clip, fitted to the second shoulder and secured in position thereon. Both shoulders are spaced from the flange.

My invention is fully shown in the drawing herewith in which the reference numerals of this description are used to indicate the corresponding parts in all the views.

Figs. 1 and 2 show in plan and side elevation a desirable form of tie-plate embodying my present invention. Figs. 3 and 4 are corresponding views of the clip or detachable hook portion. Figs. 5 and 6 show the tieplate applied respectively to wooden and to to receive and firmly to sustain the clip so that the clip-hook may operate to engage with.the rail base on the side opposite theintegral shoulder and cooperate with the latter to retain the rail in place with great security. To that end the second, or straight, shoulder may be. of any desired form that w ll firmly engage with the groovein the clip, but preferably as here shown substantially of dove-tail construction, having one or more upper flanges or enlargements 7, so

that the upper part is wider than the neck. The particular form here shown of outwardly and upwardly curved flanges is desirable for such shape of shoulder is-easy to roll and requires the minimum of metal. 'The clip 4 is correspondingly formed with claws 11 forming a groove 12 substantially to fit the dove-tail shoulder, both the shoulder and clip being of uniform size from end to end so that the clip fits the shoulder snugly, but yet may easily be slipped into place thereon after the rail has been set in position on the bed 14 between the two shoulders.

The rail is ,then firmly and positively secured in place by the two hooks, of which the c lip.-hook is maintained firmly in place by 1t s peculiarl formed shoulder against all possibility of displacement by any'fo-rce that may be exerted thereon by the rail. And by contact with the rail and therefore are not disturbed or loosened by direct strain thereonof the rail during the wave motion, and, owing to the space between the hooks and the rail flanges, the indirect effect of the wavemotion on the spikes is trifling.

There exists however the possibility of the clip slipping off gradually and longitudinally due to vibration. To counteract this some retaining means must be provided such as the spike 16 through the spike holes '17 and inclip and shoulder as shown in Fig. 5 and Figs. 1 and 3, or the special bolt 18 p I and nut of Fig. 6.

The edges of the tie-plate outside of the shoulder may be made thinner and lighter 'to save metal, but the center heavier and thicker to resist the stresses and to afford a good bed for the rail. The tie-plates are preferably balanced, that is of'equal width on each side of the central longitudinal 'axis of the rail-bed to permit reversal and convenient handling. The plates may be longer for wooden ties and shorter for metal.

My tie-plate is equally well adapted to botlf wooden andmetal ties. In Fig. 5 the tie-plate is shown in use with wooden ties, secured in place by driven spikes or screw spikes, 22, the latter form of spike bein indicated. To carry out the best plan of installing the tie-plates on wooden ties, places of plate bearing should be formed at both ends of the tie, even and flat and exactly in the same plane. When screw spikes are used,

. it is also desirable and economical to bore holes in the tie therefor and .to fasten the plates to the .ties in the shop by machines. In Fig. 6 the tie plate is shown secured to a metal tie by bolts or rivets 23; this as.- sembling'may} also be more conveniently done at the factory than in the field. The ties whether wood or metal, thus fitted with the tie-plates, are then carried-to the place of use, Wherethey' are placed in the roadbed, the .rails then set in position and "se-- curely fastened to the tie-plates and the ties by putting the clips in place on the clip shoulders. v

Furthermore my new tie-plate permits the 'convenient replacing of ties with'the track in position: A single tie may beremoved, and a new one with the tie-plates attached easily be substituted, for there is sufficient, space between the two shoulders to permit the rail to be set in position on the tieplates and,then the integral hooks adjusted to engage with both rails. The clips are then easily put in place on their shoulders and there fastened, completing the holding arrangement. I

It will be understood that I intend to leave a clear space of sufficient size betweeneach hook and the rail-base to permit the free Wave motion as above described and not so large but that at each upward movement of the rail it will engage with the hook to be held down. in place and prevented from upsetting. A space of from 9; to about inch is recommended, not above about. inch. My present invention is not limited to such space, but the tie-plate here described and claimed may be used with a space .under one hook, orunder both, or

under neither, that is the hooks may fit the flanges tight if anyone wishes so to use them,

Without departing from my present invention.

Nor do I propose to limit myself to having one 11001501 the other: on the inside but either; the integral .or detachable hook may be arranged inside or out as mostconvenient.

I so calculate the metal that the clip hook is substantially as strong 'as the integral,

'or 1n part, or certain parts bent. to shape more or less by forgingor bull-dozing. The integral shoulders may extend the full length of the tie-plates and the hooks thereon extend from end to end of the shoulder as described in my said application but I prefer to make said hooks shorter as here shown.

The clip-shoulders and clips may also beequal in length to the length'of the tie-plate, and it is preferred to so form the. clipshoulders, but the clip hooks may :be shorter and preferably substantiallyequal in length and extent of engagement with the rail flange to theintegral hooks, when they are short.' a
