RAIL TYING DEVICE Filed May 28, 1927 Patented Dec. 31, 1929 UNl'lED STATES harem" m nAIL-TYING DEVICE Application filed May 28,

1,630,697 issue-d to me by the United States Patent Office relating to rail-tying devices.

My present device relates particularly to simplified forms of the units comprising the device and'to improvement in the method of placing tension on said units. From the accompanying drawings it will be noted that 0 each grab hook is preferably made from a single metal rod bent to form; likewise each.

tie hook is preferably made from a single metal rod bent to form, and having one end sharpened so as to penetrate readily one of the surfaces of the tie. hooks is connected to the tie attachment unit by means of a bolt as indicated. It is to be un lerstood, however, that my invention is not limited to the use of grab hooks or tie attacha merit means of the particular bent-to-i orm type shown, but my invention covers also grab hooks and tie attachment means of the type shown in my Patent No 1,630,696, issued May 31, 192?, the form of the grab hooks and of the tie-attachment means shown in the said patont being, however, modified by having a round hole (instead of the square hole shown in my said previous patent) through the lower end of the grab hook, and the upper end oi the rail attachment means being modi- .i c as shown in the accompanying drawings so to pro vent the turning of the nuts. Thus 1: n'ovide for the adjustment of the tension between the grab hooks and the tie attachlo ment unit by means of the turi'ling of the bolt itself ashereinafter specified and described.

An important feature of my present device lies in the fact that ordinarily the ballast supporting a railroad tracksubstantially covers Each pair of grab 1927. Serial Nb. 195,015.

the ties so that there is only a small open space between the bottom of a rail and the surface of the subjacent ballast. .his makes it somewhat ditlicult to adjust the tension of a rail-tie device when made in the form shown in my said application, Serial No. 167,781, without reaching down through the ballast with a wrench for the purpose of turning the nut. In my present device it is necessary only toplaee the wrench close under the rail in order to contact the head of the bolt and, by turning the bolt, adjust the tension of the device on the rail and tie.

The device is shown in the accompanying draw ings wnerein Fig. 1 is a side elevation showing the railtying device as it appears when in operation in connection with a rail and a tie, the tie being shown in cross section.

F 2 is a view, partly in section, taken on the line 2 of Fig 1.

Fig 3 is a plan view, partly in section, taken on the line 33 of Fig. 1.

In tl s drawings 1 denotes a rail such as is used in ordinary railway tracks, said rail having a or flange 2.

1s tie.

42 l: are grab hooks, one part 4 of each of which overlaps the edge of the flange 2, the lower end oi each grab hook having an opening of a form which permits the turning of the bolt-like member 5, the shank of which boltlike member is preferably round (though it may be oil any other desired shape which will not interfere with its turning) and extends downwardly through the openings in the grab hooks l and also through openings in the tie contacting means 6,preferably through an ear-like portion 7 of said tie contacting means which ear-like portion has an opening sufii ciently close to the upright portion 8 to prevent the nut 9 from revolving when the bolt 5 is turned for the purpose of adjusting tension between the grab hooks and the rail-contacting member.

As hereinbefore stated, the preferred form of grab hook which I employ in this invention is made, as illustrated, from a single piece of metal rod bent to form. The grab hook in this form may be produced at very low cost and has been found to be thoroughly efficient in operation. However, as hereinbefore stated, my invention also covers a grab hook of the general form shown in my Patent No. 1,630,696, issued May 31, 1927, the only change necessary being the substitution for the square hole there shown of a hole which will permit the'turning of the bolt 5.

The preferred means of fastening the rail to the tie by the use of my present device involves, as illustrated in the accompany ng drawings, a tie-contacting element 6, having ear 7, through which a bolt 5 passes and 1s secured in place by means of the nut 9 (which nut 9 is prevented from turning by reason of the fact that one side thereof contacts the upright portion 8 of the tie contacting member 6), the said bolt extending downwardly through openings in the grab hooks 4, the head of the bolt lying above said openings. It is obvious that with the grab hooks, b olt and tiecontacting member in the position thus indicated, the tension between the elements may be adjusted by inserting a wrench in the opening 10 between the bottom of the rail and the upper surfaces of the grab hooks and turning the head portion 11 of the bolt 5. By turning the bolt and keeping the nut from turning (instead of by turning the nut and keeping the bolt from turning as is suggested in my Patent No. 1,630,696, issued May 31, 1927,) it is possible to adjust the tension between a tie and a superimposed rail without disturbing the ballast, since to do this it is necessary only to place the jaw of the wrench close up under the lower surface of the rail flange in order to engage the bolt head and turn the bolt. This feature is found in practice to be a great advantage. This type of rail-tie device also has the advantage of minimizing the likelihood of any tampering by unauthorized persons, since the entire device,

exce it the fin ers 1- shown in Fi 3 is uracl f: t) 7 tically invisible to casual observers, the device being in large part either underneath the rail or beneath the ballast so that it attracts very little attention, the fingers 4 having much the appearance of ordinary anti-creeping devices such as are frequently used on modern up-to-date railroads.

Aside from the obvious advantage of making each tie-attachment member and grab hook from a single piece of metal rod bent to form in the manner indicated, thus reducing expense for material and saving the cost of drilling holes, etc, the outstanding feature of my present invention is the special adjustment feature above described, whereby adjustment of tensionmay be made by turning the bolt itselfby applying the wrench to the head instead of turning the nut, as suggested in my previous Patent No. 1,630,696, issued May 31, 1927.

It is, of course, to be understood that the bolt heads 11 may be square, hexagonal, or of any other convenient shape. The nuts 9 are preferably square so as to prevent turning with reference to the tie-contacting unit 6 but may be of any other suitable form adapted to resist such turning motion.

While a pair of hook-shaped tie-contacting units for a single tie is shown, my invention also covers a single tie-contacting unit extending across the under side of the tie provided such unit is adapted to function as stated in connection with the other tension ing means herein shown and described. Thus such single tie-contacting unit might consist of a straight, or substantially straight, piece of metal, provided only that such unit has means adjacent the end thereof "adapted to receive the lower end of the bolt 5 and to prevent the turning of the nut 9. A section of channeled or angular steel with holes at each end would, of course, serve this purpose.

It will, of course, be understood that the same rail-attachment means which serves to prevent the rotation of the nut 9 might be used to prevent the rotation of the head 11 of the bolt 5, if the position of the bolt were reversed so that the threaded portion extended upwardly instead of downwardly as shown.
