WHEELER BARNETT, OF KNOXVILLE, TENNESSEE.

RAIL-JOINT.

Specification of Letters Patent.

Patented Mar. 7, 1911.

Application filed June 22, 1910. Serial No. 568,367.

T 0 all whom it may concern:

Be it known that I, WHEELER BARNETT, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented certain new and useful Improvements in Rail Joints, of which the following is a specification.

My invention relates to a device for connecting the adjacent ends of railway rails.

The object of this invention is to provide a device of the above character, by the employment of which the use of fish-plates or bolts is dispensed with, and which, while affording security against the lateral and vertical displacement of the rails, will also admit of the slight creeping of the rails due to the changes of temperature.

In the accompanying drawings, forming apart of this specification, and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side view of the device and showing the same as applied to the rails, Fig. 2 is a bottom plan view of the same, Fig. 3 is an end view of the same, the rail being shown in section, Fig. 4 is a horizontal sectional view taken upon the line 4 1 of Fig. 3, Fig. 5 is a view of the opposite end of the device as shown in Fig. 3, the rails being removed, Fig. 6 is a side view of a wedge constituting a portion of my invention, Fig. 7 is an end view of the same, and Fig. 8 is a side view of a modified form of wedge.

In the drawings, wherein is illustrated a preferred embodiment of my invention, the numeral 1 designates the body portion of the device, which may be termed a chair. This body portion or chair is provided as shown, with a longitudinally extending main opening 2, which is bounded upon one side by a section of material 3 having a vertical longitudinal wall 1. This opening 2 is bounded upon its opposite side by a section of material 5, spaced away from the section 3, and having an inner wall 6, which is oblique with relation to a longitudinal axis of the chair. One end of the section 5 is provided with a wall 7 having an opening 8 extending therethrough as shown. The wall 7 partially closes one end of the opening 2.- The chair 1 is further provided with longitudinally and horizontally disposed openings 9 and 10, formed through the section 3 and the wall 7 respectively. The chair is provided upon its bottom wall with plates having longitudinally disposed rows of teeth 11, as

shown. This chair may further be provided with a plurality of ribs 12. The base of the chair 1 is provided upon its longitudinal edges .with recesses 13, to receive suitable spikes. The plates provided with the teeth 11 have openings 14: extending therethrough, which register with certain of the recesses 13.

As shown in the drawings, the adjacent ends of

rails

15 and 16 are disposed within the chair, so that their bases fit within the horizontal opening 9, below the section 3. The base of the rail 15 will also fit within the opening 10 below the wall 7 The webs 17 of the

rails

15 and 16 will then engage the Wall 4: of the section 3 and be prevented from lateral displacement in that direction. The section 3 of the chair is provided with a plurality of spaced horizontal transverse openings 18, to receive removable studs 19.

The

rails

15 and 16 are provided with slightly elongated openings 20 extending through their webs 17, for the reception of the inner ends of the studs 19. It is to be understood that the openings 20 are elongated slightly in a horizontal direction, to permit of the slight longitudinal movement of the

rails

15 and 16, but said openings do not permit of the relative vertical movement of said rails with relation to the studs 19. The opening 2 above referred to, is wedgeshaped and adapted to receive a wedge 21, as shown. This wedge 21 is provided with a longitudinally disposed flange 22, to fit over the section 5, as clearly illustrated in Fig. 3. This wedge is further provided adjacent its reduced end, with an extension 23, which is normally disposed upon the wall 7 The extension 23 may be provided with an opening 24L to receive a cotter pin 25, or the like. Ad-

jacent the section 5, the base of the chair is provided with a rib 26, upon which the wedge 21 is disposed to move longitudinally, (see Figs. 3 and The rib 26 retains the wedge 21 in spaced relation to the base of the chair 1, so that the bases of the

rails

15 and 16 will fit below the wedge. The section 5 inclines inwardly from the vertical, so that the upward movement of the wedge 21 is prevented, it being understood that the wall 27 of said wedge is also inclined inwardly from the vertical, as shown.

Means are provided to hold the wedge 21 in a proper position within the opening 2, so that the

rails

15 and 16 are prevented from lateral and vertical displacements, yet permitted to have slight longitudinal movements. To this end the wedge 21 is provided with an axial opening 28, which leads into a larger opening 29. A bolt 30 is longitudinally movably mounted within the opening 28, and has a head 31 which is disposed within the opening 29, as shown. A washer 32 is preferably placed upon the bolt 30 adjacent its head 31, and a compressible coil spring 33 surrounds the portion of the bolt within the opening 29, and is confined between said washer and the end wall of said opening 29. The outer end of the bolt 30 is disposed within the opening 8 formed through the wall 7, and is screw threaded as shown at 34, for the reception of a nut 35. As clearly illustrated in Fig. 4, the wedge 21 is held in its proper position by the tension of the spring 33, and it is obvious that this tension may be varied by proper manipulation of the nut 35.

A slightly modified form of wedge is shown in Fig. 8, and the same is designated by the numeral 36. This wedge is precisely like wedge 21, except that the wedge 36 is provided upon its outer wall with longitudinally

disposedrecesses

37 and 38, to receive the bolt 30. The head of the bolt 30 and the spring 33 are disposed within the larger recess 38. In this form of wedge, it is obvious that the bolt 30 may be placed in position by a lateral movement of the same, in comparison with the longitudinal movement of said bolt when being placed within the openings of the wedge 21. lVhen the wedge has been placed in its proper position, as shown in Fig. 4, it is obvious that the same may be readily removed by unscrewing the nut 35 from the bolt 30 and removing the pin 25. Ordinarily the pin 25 does not control the movement of the bolt 30, and the same is provided in the event of the nut 35 being accidentally removed, in which case the pin 25 will engage the wall 7 and accordingly prevent the wedge from further longitudinal movement. After the wedge has been removed, the studs 19 may be readily removed from within the openings 18, by inserting a suitable tool through the outer ends of said openings and forcing said studs inwardly until the same fall within the opening 2. After the studs have been removed the

rails

15 and 16 may be withdrawn from the chair by a longitudinal movement of the same.

I wish it understood that the form of invention herewith shown and described is to be taken as a preferred example of the same,

' and that certain changes in the size, shape and arrangement of parts may be resorted to, without departing from the spirit of my invention of the scope of the sub-joined claims.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a device of the character described, a chair provided with a main longitudinally disposed opening, a wedge disposed within said opening to have slight longitudinal movement therein, a wall to partially close one end of said opening, said wedge being provided with an opening, elastic means disposed within the last named opening, and means to connect said elastic means with said wall.

2. In a device of the character described, a chair provided with a main longitudinally disposed opening, a wedge disposed within the opening to have slight longitudinal movement therein, a wall to partially close one end of said opening, said wedge being provided with a longitudinal opening, a spring disposed within said opening, a bolt connected with said spring, and means to connect said bolt with said wall.

3. In a device of the character described, a chair provided with a main longitudinally disposed opening, a wedge disposed within said opening, said wedge being provided with a longitudinal opening, elastic means disposed within the last named opening, fixed means, and adjustable connecting means between the elastic means and fixed.

means.

4. In a device of the character described, a chair provided with a main opening, a wedge to be disposed within said main opening to have slight longitudinal movements therein, and means arranged within said wedge to yieldingly restrict such movements.

5. In a device of the character described,
