SPECIFICATION forming part of Letters Patent No. 637,827, dated November 28, 1899.
Application filed August 31, 1899. Serial No. 729,124. (No model.)
To aZZ whont it may concern.-
Be it known that LHENRY C. QUESENBERRY, a citizen of the United States, residing at North Tazewell, in the county of Tazewell and State of Virginia, have invented a new and useful Rail-Joint Closer, of which the following is a specification.
, This invention relates to rail-joint closers. The device is intended to be applied for adapting the positions of railroad-rails with respect to each other, to close or open the joints, and comprehends a pair of clamps and mechanism connecting the clamps and operating first to efiect the clamping of the rails and then to move the clamps with respect to each other for the purpose of opening or closing the joints.
The specific construction of the invention and its application will appear more fully hereinafter.
Referring to the drawings, Figure l is aperspective view of the contiguous ends of two rails with my adjustment applied in use. Fig. 2 is a sectional view through the rail, one of the clamps, and the draw-rod, the clamping-bolt being shown in elevation. Fig. 3 is a detail perspective view of one of the clamps. Fig. 4is a detail perspective view of the drawrod, its nut, and washers. Fig. 5 is a bottom plan view of one of the clamps and a fragment of rail, the clamped position of the former being illustrated in dotted lines; and Fig. 6 is a detail view of one of the jaws 9 with a portion of its arm broken away. Fig. 7 shows a different arrangement of the parts for separating or increasing the separation of the ends of the rails.
Referring to the numerals of reference, indicating corresponding parts throughout the several views, 1 and 2 indicate the contiguous ends of a pair of rails constituting sections of a railway-track, and 3 indicates an open rail-joint to be closed quickly and with a minimum expenditure of labor.
My rail-adjustment comprises a pair of clamps 4 and 5, arranged to grip the bedfianges 6 of the rails and to be urged together to effect the closing of the joint by what may be designated a draw-rod 7, passing through the outer ends of arms 8, extending from the clamps 4 and 5. Inasmuch as'the clamps 4 and 5 are constructed identically, I will describe one of them in detail and will then deor wrench-lug l5.
fine its relation to the other. The clamp comprises a pair of jaws 9 and 10, through the lower ends of which is passed a clamping-bolt 11, screw-threaded at one end, as indicated at 12, to engage internal screw-threads in the bolt-opening 13 of the jaw 9. The outer end of the boltthat is to say, the end opposite the thread 12is enlarged or headed, as indicated at 14, and terminates in a squared end The opening 16 in the jaw 10, through which the clamping-bolt passes, is smooth or unthreaded for the reception of a plain portion of the bolt in order that the latter when turned by the application of the Wrench to the wrench-lug will draw the jaws together. The contiguous or inner faces of the jaws are provided with flange-recesses l7 and 18 for the reception of the bed-flanges of the rails and defined by horizontal ledges 19 and 20 and overhanging biting-flanges 21 and 22. The flange 22 is serrated or toothed at its edge, as indicated at 23, to cause it to bite into the bed-flange and possiblyinto the web of the rail. This biting-flange 22 at the upper edge of the jaw 10 practically conforms to the somewhat-inclined surface of the bedflange, and the depressions forming the ser rations orteeth 23 may, if desired, be extended partially or entirely across the bottom face of the flange to obtain a maximum frictional surface to prevent slipping of the jaw when clamped upon the rail.
The biting-flange 21 of the jaw 9 is extended beyond the side of the jaw and somewhat beyond the edge of the opposite end of the flange and is sharpened, this extension constituting what may be termed a beak 24 at that point upon the clamp which receives the greatest strain and located immediately over a corresponding beak 25, projecting from the contiguous end of the'ledge 17.
Extending from the jaw 9 in the general direction of the bolt 11, but having a slight upward inclination, is the arm 8, heretofore referred to, provided at its end opposite the clamp with the slightly-elongated opening 26 for the reception of the draw-rod 7, and in its outer face and at diametrically opposite sides of the opening 26 is formed with notches 27, for a purpose to be defined.
In practice a clamp thus constructed is connected to the rail by passing the opposite edges of the rail-bed flanges 6 through the recesses17.='amdi1'8.
opposite sides of the rail, causing the serra- (ions 23 of the biting-flange 22 to bite into the bed-flange and at the same timebringing the; beak 24 into contact itsr'ed'ge with basebf the Web of the rail, the beak extending under the rail nearly to the edge of the ledge 18. A second clamp, identically construct-ed, is then placed upon a contiguous rail,.and; the outer ends of the arms 8 are connected. by mechanism which serves to draw them to-' gether with considerable pressure.
Inasmuch as .the beaks 24 and 25 of the jaws 9 arelocated adjacent to :;the contiguous facesiof the clamps, the applicatlion of .PI'GS- i sure to :theouterends of the-arms iniopposite dilBGYUlOIlSgOIj, \iniotherwords, in theadirection j of each-other, =Wi=ll5fi PSi Eefli8CU the tightening; of the clamps upon the rails, and continued pres-sunewill :then eifect the "closing .of the joint by the'drawing up of the ra ilfsections.
.iIt has been asserted that the exertion ofi ipressure on, more sprop'erly,"of opposed pressures, upon the ou'ter' endsof the'arm-s S will? eifectthezclarmpingzof the rails. This :is by :reason of the fact that the :pressure exerted alzponthe clanrps is directed in agplane substantially parallel with the gripping-faces, but :atga ipoint-sorfarito one sideof the clamps "fthatratorsionalstrainiseiiected. This causes the beaks .24 to biteiintotherails andzto limit mhe twisting or torsional movement of :the aclamips. :ln-thismon nection the Jfunction-of v the beak 25 will appear, since itsmaysomie- Jti meshapPemtlhat th'e beaks24not beingsu-fliici-entlgy extended :to-reach -t he web'of the rail xa consi dera ble lateral strain 'w ill iloe -exerted upon the :bolts 11 which nnight result rl-nthe b'endingio'f :the :bolts were it not for the provvision of these lower beaks 25, which, ex-
