Patented May 270, 1930 PATENT OFFICE .IUsTUs J. Ross, or HUNmINGfromWEs'r VIRGINIA EXTENSION-RAIL CLIP Application filed April 23,

This invention relates to the construction of clips for mine ties and rails, and has special reference to means for temporarily securing extensionrails in inverted position in order that they may serve. as a temporary track at the working face of the mine until such time as the face is moved back suiiiciently to permit rails to be'laid in upright position in the usual manner; thereby avoid- Y ing the use of short pieces of rail which often cause deraihnent with a consequent loss of time to the coal loader as well as an expense to the operator in replacing the car.

An object ofthe invention resides in the 35 provision of a clip of inexpensive construc.

tion which may be readily and quickly applied to the tiesV so asjto firmly and securely lock the inverted rails in place and which may be removed with equal facility.

Another object of the invention consists in so constructing the clips that they may be operated by unskilled labor to provide the proper gauge and without danger of spreadin rails or the like, due to faulty application 5 of the fastening means. 1

A further object of the invention resides in the provision of clips which may be applied without the use of special tools, thereby further facilitating the laying of the eXten- 0 sion rails by the ordinaryhelp found about themines.

Other objects .and advantages of the invention will be apparent from the following description when taken in connection with the accompanying drawings; in which Figure 1 is a plan view, partly broken away, showing the usual arrangement of inverted extension rails to provide a track extension for the working places of a mine.

Figure 11 is a detail view of the clip shown in F igureV 10, parts being broken away to show the details of construction.

Referring to the drawings in greater detail and especially to Figures 1 to 5 inciusive, the numeral 1 indicates a mine tie of any desired construction, preferably of metal, and provided with alignment lugs 2 and rail securing clips 3. These ties, of course, are laidin 5 the usual manner and the rails 4 are secured in position on the ties by means of the rotatably-mounted clips 3.

lVhen laying rails at .the working place in a mine it is quite often found desirable, due 80 to the llnited space, to invert the rails and clamp the ends thereof against the sides of the upright rails as indicated in Figures 1 porarily increased in length from time to time S" vuntil it is found desirable to lay the increased length of track inthe usual form with the rails in upright position. The present invention relates to means for quickly and accurately .securing these inverted rails in position.

As clearly indicated in Figures 2, 4 and 5, the outside clip 3 is provided with an aperture 5 adaptedk to receive the L-shaped nger 6 of the extension clip 7. In applying the extension clip to the rail clip, the latter is first turned so that its aperture 5 overhangs the side of the tie; the finger 6 may then be inserted into the aperture and the clip 3 turned to the position shown in Figures 2 and 5. In this position the flat portion of the finger is in contact with the upper surface of the tie and the extension clip is thus locked against disengagement from the tie clip until the latter is again turned to a position in which its aperture 5 overhangs the side of the tie.

The extension clip 7 is provided with a channel or pocket 8 on its upper end for the reception of a wedge 9 which is driven into the space between the back wall ofthe pocket and the web of the inverted rail-so as to tightly clamp the inverted rail against the overlapping portion of the upright rail or against th`e clip on the opposite side of the rail. In Figure 5 I have shown an additional wedge 10 for use in places where the tie is not solidly supported on the ground or floor; this second wedge thus serves to prevent sagging of the tie away from the rail under such circumstances.

With the foregoing construction of eXtension clip and attaching means therefor it will be readily apparent that the inverted eXtension rails may be easily and quickly applied and removed without the use of skilled labor and without the use of any special tools, thereby avoiding 'delays which would otherwise be caused while waiting for the track to be extended up to the working face of the mine.

In Figures l and 3 I have illustrated the use of a tie placed on the top of the inverted rails to serve as a bumper to prevent cars from ruiming off the end of the track; this is an ordinary and well known construction and forms no part of the present invention.

In Figure 6 I have shown a modified construction of extension clip in which the clip 20 is provided with one or more fingers 21 which are adapte-d to pass through openings 22 in the clip 3 and tie 1. In this embodiment of the invention it will be observed that the extension clip may be placed in rail securing position while the clip 3 continues to serve as a fastening means for the upright rail et. In this form as well as that previously described a wedge 23 is driven between the clip and the inverted rail so as to securely hold the latter in place.

Figures 8 and 9 illustrate a. still further embodiment of the invention in which the eX- tension clip 30 is provided with a pair of fingers 31 bent back upon themselves so as to engage over the edge of the clip 3 when the latter is turned through 180 from its rail engaging position. From an inspection of Figure 9 it will be apparent that one of the fingers or hooks 31 extends over the edge of the clip 3 at one side of the tie while the other finger passes through an opening 33 in the plate so as to extend below the edge of the clip. The extension clip is thus anchored to the clip 3 and provides a bearing for the wedge 34 which forces the inverted rail malse against the upright rail so as to securely fasten the former and provide the proper gauge.

Another modified form of the invention is disclosed in Figures 10 and 11, in which the rivet which pivotally connects the clip 3 to the tie is provided with a supplemental head or button 42 for engagement with'the key-hole slot 4l formed in the extension clip 40. As in the several previously describe `l forms of clips7 the clip 40'is` constructed to provide a pocket to receive one edge of the clamping wedge 43.

From the foregoing description it will be apparent that I have devised an extension clip which may assume a variety of forms but in all of which is provided means by which the clip may be readily and quickly applied to and removed from fastening position without the use of tools or skilled labor, and in which a pocket is provided for reception of the usual locking wedge. It will be further apparent that the extension rail clip as depicted herein is formed of a single piece of metal, is strong and durable in operation, and may be applied to the tie without multilation of the latter.

In accordance with the patent statutes I have described what I now believe to be the best embodiment of the invention, but I do not wish to be understood thereby as limiting myself or the scope of the invention7 as many changes and modifications may be made without departing from the spirit of the invention; all such I aim to include in the scope of the appended claims.
