ALBERT C. JORN S, OF DAYTON, TERRITORY OF NEW MEXICO.

RAIL-JOINT.

Specification of Letters Patent.

Patented Mar. 21, 1911.

Application filed April 14, 1910. Serial No. 555,333.

To all whom it may concern:

Be it known that I ALBERT G. JOHNS, a citizen of the United States, residing at Dayton, county of Eddy, and Territory of=- New Mexico, have invented certain new and useful Im rovements in Rail-Joints, of which the ollowing is a specification.

Myinvention relates to rail joints that is to means for connecting the abutting ends of railway rails to'-form a continuous rail The object of my invention is to provide a simple and efficient rail joint whereby the rails may be readily and quickly secured together.

A further object of my invention is to.

provide a rail oint-whereby the abutting ends of the rails will be maintained in per-' feet alinement.

Other ok ijectsv will appear hereinafter.

My invention will be more readily understood by reference to the accompanying drawingsformi'ng a part of this specification and in .which- Figure 1 is a perspective-view of the abutting ends of two rails with the block shown in position and the fish plates removed, Fig. 2 is a vertical transverse section through the rail joint taken on the line separating the rails, Fig. 3 is a central longitu dinal section through the rails and, joint, and Fig. 4 is a erspective view of the dou- 7 ble dovetailed b ock.

' This preferablyl Referring now to the drawings 1 and 2 indicate the abutting ends of two' rails which may be of any ordinary or preferred form. In the drawings I have illustrated the ordivnarv l' rail comprisin I the ball 3, web 4 and; flange 5. T

e en s of the webs, 4 are formed with dove-tail recesses 6 which are of equal size and similarly positioned and may be readily formed therein. Arranged in the recesses 6 is a double: dove-tailed block 7. fits snugly in said recesses and is prefera y ofthe same thickness as the webs 4 of the rails. It is not objectionable for the block to be a trifle thinner than the web but it shouldnot be thicker than the saine for obvious reasons.

Secured'upon each side of the webs 4 are a pair of fish plates 88 which are preferably angle irons as shown in Fig. The

fish plates entirely inclose the block 7 and are held in position by a pairof bolts 99 which extend through bolt holes. 10 in the web 4 of the rails. Two bolts are suificient to hold the fish plates in position and consequently there is a great saving in the number of bolts required to lay the track. Further with the block 7-in position the loosening of one of the bolts would not be as serious; a matter as with the rail joint at present in general use.

The contracted central portion of the block 7 is formed with 'a circular enlargeprovided with a transverse bolt hole -12. A single bolt may extend through the merit l1 fish plates and the block to hold the parts in position, the ends of the fish plates extending over the adjacent portions of the webs of the rail. Although a single bolt is usually sufficient; additional boltsmay be employed as above described. I

By forming the blocks and fish plates separatel they may each be rolled out of high gra e steel and at a lowcost. Further the joint is easy to assemble. and will positively lock the ends of the rails in perfect alinement.

Having described my invention what I- claim as new and desire to secure by Letters Patent is: p s

In a rail joint, the abutting ends of the rail, provided with dove-tail notches or. recesses in the web portions thereof, a double dove-tailed block fitting in s'aid,recesses and of substantially the same thickness as. the webs of-the rail and of uniform thickness throughout its length, the central portion of said block being f ormed with .afcircular enlargement and provided with a transverse. bolt hole, fish platesof ordinary form upon opposite sides oftlie webs of, the rails and inclosing said block and a boltextending through the same and said bolt hole, substantially as described; v In testimony wheregf I have signed my name to this'specificatiibn in the presence of. two subscribing witnesses.
