ANTICREEPING ATTACHMENT FOR RAILS.

Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed April 30, 1906. Serial No. 314,326.

To tZZ whom it may c0ncern.-' I

Be it known that I, TRACY L. PA1NE, a 5 citizen of the United States, and a resident of I Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain 5 new and useful Improvements in Anticreeping Attachments for Rails; and I do hereby declare that the following is a full, clear, and i exact description thereofi 'l he object of my invention is to provide a simple and effective device to-prevent creeping of rails, the construction of its members being Siltll that when clamped to a rail they j engage eath other to form a knuckle-joint, thereby coactin to relieve the strain upon I the clampingbolt and increase their gripping elliciency, sai invention consisting in cerl tain peculiarities of construction and combination of parts, as hereinafter fully set forth 1 with reference to the accompanying drawings 5 and subsequently claimed.

In the drawings, Figure 1 represents a seqtional view of an anticreeping rail-clamp e lnbcdylng the features of my invention, tie

clamp being shown adjusted to arail-llange with parts broken away and in section, as indicated by line 1 1 of Fig. 2; Fig. 2, a plan 2 ol' the preceding figure with a portion of j the tic-bolt broken away to better illustrate the invention; Fig. 3, a side elevation of the clamp, showing its position with relation to 1 the tie and rail, the direction oi the creep of the rail being indicated by an arrow; and i l ig. 4, a cross-section thereof upon line 4 4 of Fig. 2. 1

Referring by letter to the drawings, A A indicate heads of jaws ll B, the rail-gripping i'accs ol which jaws arol'orined by upper and lower lips (7 the lower lips t) being intcrj rupted by bolt-openings (1, into which is lit- 5 ted the usual tie-bolt 1), hold in place by a nut I), threaded therein. 'i he jaws have vcrl tical Llungcs l), arranged to abut the lace of an adjacent rail-tic l, which llangcs l'orin continuations ol' liorizontall vinclined l'cct (l (l, extending from heads A X oi each jaw. 'lhc l'oot (l of jaw A is provided" w ith a socket /ll, directly under and alincd with tho tic bolt, while l'oot, (l ol-thc opposite jaw has, a correspond]ugly-located prclcmbl-y scniispherical horizontal lug ll, which is littcd into the socket ll aforesaid,,whcrcb thc jaws are supported one by the other, and j the other, and

o I n l sectional view oi" same as indicated by line j l thus held against tendency to spread apart at the bottom w hen hung upon a rail preparatory to the placing of the tie-bolt .l) in working position and the running of the nut b thereon, there being metal above and below said lug when the same is engaged with said socket, as is clearly shown in Fig. 1, to pro- "ide for the supporting of said jaws one by thus prevent separation of the same in a vertical direction, as well as laterally, when the tic-bolt is tightened.

By the foregoing description it is obviousthat when the jaw members are drawn together by the tiebolt they will fulcrum upon each other at their respective ball-and-socket connections and exert a direct grip u on the rail on the mechanical principle 0 a ever of the second class, the tie-bolt or power being between the fulcrum and load, thereby di- Viding L116 strain in such a manner as to eliminate all tendency of said bolt to buckle, a resultwhich is unavoidable in devices of this character, wherein the jaw members are disconnected and depend upon the unsupported draw of the tic-bolt for their grip upon the raiHlanges.

While I have shown and described one form of jaw, it is apparent that this form maybe varied indclinit'olyto suit the different requirements without departing from the spiljt of my invention.

I claim-' I 1. An anticrecping attachment for rails comprising a pair of clamping-jaws having rail-gripping faces and depending opposing feet having horizontal supporting engagewent one with the. otherotolprevent their separation in a]vcrtiiaildirection, a tic-bolt ongageablc with'the jaws, and a nut engageable with the bolt. s 2

'2. An anticreeping attachment for rails comprising a pair of clamping-jaws having rail-gripping faces and depending feet, a horizontal lug on-the l'oot of one jaw engaging a socket in the foot of the other jaw whereby bpth jaws are supported one by the other to prevent their scpi'n'ation in a vertical direction, a tic-bolt engagcable with the jaws, and

a nut eng.-igcablo with the bolt.

3;. An anticrccping attachment for rails comprising a pair olclamping-jaws having rail-gripping laces and depending feet, a lug on the foot of one jaw extending into a socket in the other jaw, whereby it is opposed above and below by the material of the latter jaw, the county of Milwa ukee' and State of Vistb th us provid z for the mutual suppor? of cousin, in the presence of two Witnesses. both aws and lmmovablhty of the same 111 a v TRACY L. PAINEI' vertical direction, a tie-bolt engageable with 1 said jaws and a nut run 0 n thv bolt. l Witnesses:

In tosumony that I clann the foregolng I i GEO. YOUNG, have hereunto set my hand, at Mflwaukee, 1n 1 N. E. OLIPIIAN'I.
