9 Claims. (01. 238+-304) This invention relates to rail tie-plate assemblies, one 01' the objects being to safely secure railroad rails. Another object is to secure them so they may be easily shifted when their heads becomeworn. Other objects may be inferred.

A specific example of the invention is illustrated by the accompanying drawings, thevarious figures being as follows:

Figures 1 and 2 are side views of the tie-plate assembly, showing the shifting of the rail.

Fig re 8 is a cross-section from the line m-in of Figure 2.

Figures 4 and 5 are top plans of details from the first two figures.

lugs provided thereby. It has n thick central portion 5 whose top surface is inclined at the proper angle to give the rail its desiredcent. This portion'incidentelly acts. as a, reenforcement above the groove.

In the drawings, the bar E is looped at points calculated to enable the resulting lugs 2 to addecently straddle the base of the'roilto be secured. Clips 5, 6 have end portions 3 adapted to engage the base of the rail, and ere respectively epertured at difierent distances from these portions for application to the lugs 2. Thus, they are adapted to hold the rail st different positions when interchanged on-the lugs.

Referring to the side elevation, the left-hand blip E is epertured nearer to its end portion i then is the right-hand clip 3. This the reil with its center line offset to the leit from the middle point between the ings Kt is be understood that lugs spec-ed our ficientiy to permit some movement the sell therebetween.

This roll is assumed to be the highest oi e. curved track section. the right-trend side oi? its head beingthereioi'e subjected to rather rapid wedge-seat 8 constructed to engage it when inserted in the lug to which it is applied. This wedge-seat has a downward projection 9 which registers with the aperture in the clip. An arcuate wedge l0 engages the top of the wedgeseat 8 and the under side of the lug.

The wedge-seat end the lugare respectively constructed to provide arcuatc surfaces for receiving the wedge. The upper surface of the wedge itself is laterally curv ed to fit the lug.

The wedge is sufliciently long so its small end projects beyond thesuriace of the lug and wedge= seat, ,and it is made of malleable metal so this end may be displaced to lock it against removal.

An alternate means for holding a. clip on its lug includes a. spring piece it having o. control downwardly looped portion which projects into the aperture of the clip when the piece is placed in the lug. 1

A headed bolt 82 is then inserted through the lug, on unthreaded member it, having flat sides arranged difierent distances from the axis of the bolt, being first applied thereto. A threaded member 5 3, similarly constructed to the member i3, is adapted for screw-threaded engagement with the bolt i2. Similar sides of the two members are faced towards the spring piece it, and the heed of the bolt it turned to eflect engoge= merit. verying forces which depend upon which of the sides of the two members are faced towards the spring piece it, the letter preventing looseness.

The bolt is sumciently long to enable rotation of the member to for e few turns before engagemerit of the spring piece ii is efiected, es it would be troublesome to start the bolt into this member if otherwise.

Although a. specific example of this invention is disclosed in accordance with the patent statutes,- it is evident that various subcombinations of the whole might be used with other constructions; therefore, the invention is not to be limited exactly thereto except as defined in the fol lowing claims.

We claim:

1. A tie-plate assembly including s. bar which is upwardly looped at at least one point to provide a. lug adjacent the base oi. a rail when the bar is placed thereunder, and a rail base-plate heving a groove in iin bottom receiving said her and which isof a. depth at least equal to the thickness of the letter, said groove-being apertured at at point registering with the lug provided thereby,

Thus, the clip may be held down with said base-plate being thereby adapted to carry the rail and position said bar.

2. A tie-plate assembly including a lug, a clip apertured for application to said lug, an arcuate wedge and a wedge-seat constructed to engage said clip, said wedge-seat and'said lug being constructed to provide opposed surfaces for receiving said wedge.

3. A tie-plate assembly including a lug, a clip apertured for application to said lug, an-arcuate wedge and a wedge-seat constructed to engage said clip, said wedge-seat and said lug being respectively constructed to provide arcuate surfaces for receiving said wedge therebetween, and said wedge being constructed of malleable metal and of sufiicient length for its small end to project beyond the surfaces of said lug and wedge whereby its end may be displaced for locking purposes.

4. A tie-plate assembly including a lug, a clip apertured for application to said lug, an arcuate wedge and a wedge-seat constructed 'for application to said clip and having a downward projection registering with the aperture therein, said wedge-seat and said lug being respectively constructed to provide arcuate surfaces for receiving said wedge therebetween, and said wedge being constructed with its upper arcuate surface curved to fit the lug and, further, being of malleable metal and of sufiicient length for its small end to project beyond the surfaces of the lug and wedge-seat whereby it may be displaced for locking purposes.

5. A tie-plate assembly including a bar which is upwardly looped at one or more points to provide a lug or lugs adjacent the base of a rail when the bar is placed thereunder, and a rail base-plate having a central thick portion, a groove in its bottom, this for receiving said bar, and apertures at points registering with said lugs provided. by said bar when in said groove, the latter being of a depth at least equal to the thickness of said bar.

6. A tie plate assembly including a bar which is upwardly looped at spaced points to provide a pair of upstanding lugs that can straddle the base of a rail, a rail base-plate: having a groove in its bottom receiving said bar and which is of a depth at least equal to the thickness of thelatter, said groove being apertured at points regis-. tering with the lugs provided thereby, said baseplate being thereby adapted to position said bar and carry a rail, clips having end portions for engaging the base of a rail and being respectively apertured at different points from these ends for application to the lugs provided by said bar, said clips being thereby adapted to hold the rail at different positions when interchanged on said lugs, and means for holding said clips on said lugs.

'7. A tie-plate assembly including a bar that is upwardly looped at at least one point to provide a lug adjacent the base of a rail when the bar is placed thereunder and a rail base plate having a groove in its bottom receiving said bar and a thickened portion that is in line with said groove, the latter being of a depth at least equal to the thickness of said bar, said plate being apertured at a point registering with said lug so that the latter may project upwardly therethrough. v

8. A tie-plate assembly including a bar that is upwardly looped at at least one point to provide a lug adjacent the base of a rail when the bar is placed thereunder, a rail base plate having a groove in its bottom receiving said bar and a thickened portion that is in line with said groove, the latter being of a depth at least equal to the thickness of said bar, said plate being apertured at a point registering with said lug so that the latter may project upwardly therethrough, a clip that is apertured for application over said lug, a wedge-seat constructed for passage through said lug transversely above said clip and a wedge member constructed for passage through said lug and adapted to bear on said wedge-seat.

9. A tie-plate assembly including a lug, a clip apertured for application to said lug, a spring piece constructed for passage through said lug above said clip, a headed bolt for insertion through said lug above said clip and said piece, an unthreaded member having flat sides arranged different distances from its center and adapted to receive said bolt, and a threaded member similarly constructed to said first named member and adapted for screw-threaded engagement with said bolt, the first and second named members being adapted to hold down said clip with varying forces by contact of their various sides therewith and said piece being adapted to frictionally hold said members in place, said bolt being sufilciently long so that when passed through said unthreaded member and through said lug its end may be threaded into engagement with said threaded member while both of said members are mutually separated sufiiciently to be free from the full pressure of said spring piece thereagainst.
