CHARLES C. MITCHEL, OF LYNDHURST, NEW JERSEY.

FASTENER FOR RAILWAY-RAILS.

To all whom t may concern.'

Be it known that I, CHARLES C. MrrcHnL, a citizen of the United States, residing` at Lyndhurst, in the county of `Bergen and State of New Jersey, have invented a certain ne and useful mprovement in Fasteners vfor Railway-Rails, of which the following is and which will hold the rail reliably whileY avoiding the objectionable rigidity attending the use of fasteners of this character, and

which may be manufactured and applied economically, and is especiallyadapted for service' with metal ties. Y

The invention consists in certain novel features of construction and arrangementby which the above objects are attained, to be hereinafter described and pointed out in the claims. i

The accompanying drawings form a part of this specification and show an approved form of the invention.

Figure l is a plan view of two metal ties and portions of the rails thereon, equipped with the improved fastener. Fig. 2 is a corresponding side view. The remaining figures are on a larger scale. Fig. 3 is a transverse section through a rail and portion of the tie, showing the fastening means in elevation. Fig. 4L is a corresponding central vertical section. Fig. 5 is a top or plan view of a shoe forming part of the fastening means.

Similar letters of reference indicate the same parts in all the figures.

A is the head of the rail and B the tie upon which the rail rests, shown as of metal rolled to channel form with depending flanges B1 B1 at the sides, adapted to engage the roadbed and ballast. Cn each side of the rail and rigidly secured to the upper face of the tie is a plate C held by bolts or rivets C1 and rabbeted at c on the under face adjacent to the rail to form an overhanging flange C2 extending parallel with the rail-base A2 and projecting nearly to the edge thereof.

D D are shoes which may be malleable castings or rolled steel, of general L-shape in cross-section, each having an upright Specification of Letters Patent.

Application filed November 29, 1912. Serial No. 733,959.

flange D1 shaped on the inner face to match to the contour of t-he rail-web A1 and eX tend to and engage beneath the under face of the rail-head A, and a lateral or horizontal flange D2 matching to the upper face of the base-flange A2 and extending beyond the latter and beneath the overhanging flange C2 of the plate C, to abut against the Vertical interior wall of the rabbet c. Each shoe is preferably tapered vor inclined on the outer margin of the flange D2, as indicated to an exaggerated degree at (Z in Fig. 5, and both shoes are to be driven by blows of a hammer or other tool into firm frictional or wedging engagement in the rabbet c beneath the flange C2 and against the adjacent rail surface. Thus engaged the rail is securely fastened to the tie and held in alinement, but the engagement ofthe shoes is such as to permit the rail to yield laterally under great train-pressure, to an extremely small extent by reason of the resiliency of the shoe and plate, and thus avoid objectionable rigidity.

Any preferred means 'may be employed to prevent a reverse movement of the shoes longitudinally of the rail and the consequent loosening of the connection,that shown consistsvof a latch E applied behind the shoe when the latter has been driven home with its, rear face flush with the adjacent side of the plate. The latch is secured to the plate by a stud-bolt F and may be turned up out of the way, as shown at the left in Fig. 3, while the shoe is being inserted and driven. It is then turned down to cover a portion of the flanges C2 and D2, with its lower free corner and part of its edge engaged in a slot b provided in the tie at the proper location, and thus locks the shoe in place and effectually bars accidental withdrawal.

Modifications may be made in the forms and proportions as found necessary or desirable in adapting the invention to various types and sizes of rails and conditions of traffic. l

The plate C may be bolted to a wooden tie with a tie-plate beneath rail, and other means than the latch may be employed to hold the shoe and plate C in the desired relative positions. The taper or incline of the base of the shoe may be very slight to permit the shoe to be accurately driven to the desired distance.

I claim l. In a device of the character set forth, a

tie, a rail thereon, plates secured to said tie on opposite sides of said rail, each having an overhanging flange adjacent to said rail, a shoe on each side of said rail, each constructed to abut against the web of such rail and the under face of the head thereof, and engage beneath said flange, and pivoted gravitating means for locking said shoe in engagement with said flange.

2. In a device of the character set forth, a tie, a rail thereon, plates secured to said tie on opposite sides of said rail, each having' an overhanging flange adjacent to said rail, a shoe on each side of said rail, each constructed to abut against the web of such rail and the under face of the head thereof, and engage beneath said flange, and latch pivotalljr attached to said plate and constructed to lie against said shoe to prevent its movement.

3. In a device of the character set forth, a tie, a rail thereon, plates secured to said tie on opposite sides of said rail, a rabbet on each of said plates adjacent to said rail, a shoe on each side of said rail, each constructed to match to the base, web and under face of the head of said rail and engage in said rahbet, said shoe having its outer edge inclined lengthwise to produce a .vedge-like engagement With said rabbet and rail, and gravitating means for locking said shoe in such engagement With said plate to prevent releasing movements of said shoe.

a. In a device of the character set forth, a

tie, a rail thereon, plates secured to said tie constructed to lie against the rear face of said shoe to prevent releasing movements thereof. y

ln a device of the character set forth, a tie, a. rail thereon, plates secured to said tie on opposite sides of said rail, each having an overhanging flange. adjacent to said rail, a shoe on each side of said rail, each construct ed to abut against the Web of such rail and the under face of the head thereof, and engage beneath said flange, and a latch pivotally attached to said plate and constructed to lie against said shoe to prevent the ivithdraWal of the latter, said tie having a slot in which the Iree end of said latch is received and engaged.

ln testimony that l claim the invention above set. forth I aflix my signature, in presence of tivo Witnesses.
