UNITED STATES W LIJAM 11- L WI qr PITTSBURGH. .PE,N. AN A aamn epksm Application filed June 29, 1925. sen-a1 naaa'wof To all whom it may concern:
Be it known that I OLIVER P. MEGAHAN,
a citizen of the, United States, residing at New Castle, in the county of'Lawrence' and State of Pennsylvania, h'ave'invented a certain new and useful Improvement in Rail- -road Ties, of'which' the following is aspect fication.
According to railroad engineers arolled I-beam makes a substantial and durable cross tie for light work such as on street railways, but for railroads where the traflic is heavy a beam of that form is too rigid and lacks the resiliency necessary for the 5 preservation of the integrity of the rolling stock. I
The object of the present invention is the provision of means whereby the I-beam can be utilized and resilience obtained adapting it for use on heavy traific roads.
The invention is embodied in the examples herein shown and described, the features of novelty being finally claimed.
In the accompanying drawing Figure 1 is a perspective view showing the fractions of rails supportal on the cross tie and chairs.
Fig. 2 is a'view in side elevation of the same looking toward the end of the tie and the side of a rail thereon.
Fig. 3 is an elevation looking at the side of the tie and an end of a rail supported therein.
Fig. 4 is a top plan view of the chair and a buffer therein.
Fig. 5 is a view like Fig. 2 showing a modification in which the chair is made as an integral part of the tie.
Fig. 6 is also a view like Fig. 2 showing a modification in which the upper cross part of the head of the tie is rounded or bent and the base of the chair correspondingly rounded to fit thereon.
In the views and referring more particularly to Figs. 1 to 4 the character 7 desig- 1 nates the cross tie which is of rolled iron I- beam form and of the usual or suitable length to support the two rails 8.
The chair which is of yoke-form consists of an iron or steel plate having a base or intermediate portion 9 with its ends 9 bent up divergently from each other and then outwardly as shown at 9 to form seats upon secured to thehead flanges oft-he I b whichthe'rail is supported.- The I chair; is
by means ofthreaded bol'tslO having n s 11 i thereon, spring washers being interposed between the nuts and the I-beain' flange: -j The rail-is secnred "toIthe twisty- 1a bolt 13 having 'spi-ke-like head "that' la-ps over the baseor the ma,- a nut 14 being provided" to: hold the bolt fairly firmly gripped to the rail. The bolts 13 have square shanks andthe flanges 9 are provided with square holes 15 to keep the heads of the bolts 13 from turning out of functioning-position.
Loosely seated in the chair is a curved spring 16. This spring is made of such length that it rests on the intermediate portion 9 and fits at its terminals closely in the corners formed at the junction of the bent up portions 9 with the base or intermedi I ate portion 90f the chair. The spring 16 is made of such width. that its terminals are adjacent the heads of the bolts 10 and the spring is prevented from dislodgmentin a horizontal direction from its position under the rail. Said spring further is made of a depth so that normally it does not contact with the, lower side of the rail but of such depth that when the rail is depressed with 7 an abnormal load it serves'as a bufi'er.
The parts 9 are made resilient so that when the load passes over the rail there is a yielding efl'ect akin to that obtained with awooden tie. In this action the parts 9 are slightly spread but this is permitted. by reason of the slipping spike like heads of the bolts 13. I
In Fig. 5 the spring members 9 corresponding to the spring members 9 of Figs. 1-4 are integral with the I-beam, otherwise the construction and mode of operation are the same. I
In Fig. 6 the upper surface'of the tie and 95 the lower face of the chair are correspondingly curved so that the joint at 17 between them prevents horizontal slippage in the direction of the track. The efi'ect of this form of joint is that possible tendency of horizontal strain to cut the bolts 13 is avoided.
The base flanges of the tie are shown as provided with spurs 18 cut in the opposite margins and bent down, such spurs afl'ording a better grip of the tie upon the road bed and preventing creeping.
The forms of the parts can be changed without departing from the gist of the invention as claimed.
What I claim is:
1. A chair for a railroad tie consisting of a pair of opposingly inclined resilient members and a resilient buffer member interposed between said inclined members.
2. A chair for a railroad tie consisting of a pair of opposingly inclined resilient members and a curved resilient buit erlmember interposed between said inclined members.
8. A chair for a railroad; tie consisting of a base portion having its ends bent to form resilient rail receiving members, means for securing said base portion tothe tie body, and a resilient buffer member seated on said base and held'from dislodgment horizontally by said securing members.
4. A rigid railroad tie body and a chair therefor consisting of a pair of opposingly inclined resilient members and yielding means for securing the rail thereto.
7 5. A chair for a railroad tie consisting of a plate having its end portions bent upwardly to form divergently inclined resilient members and means whereby a rail may be secured to said end portions.
6. A chair for a railroad tie consisting of a plate having its end portions bent to form divergently inclined resilient members, means whereby a rail may be secured thereto and an upwardly curved resilient buffer member placed between said inclined resilient members. 4
7. A chair for a railroad tie consisting of a plate having its endportions bent to form divergently inclined resilient members and means for securing the chair to the tie body adapted to prevent slippage in relation thereto.
