Specification of Letters Patent.

patented Dec. 2l., time.

Application filed November 5, 1908. Serial No. 461,215.

To all whom it may concern: K. Y

Bc 1t known that we, JOHN .SKAALA and Ezuitran H. lliLLrAnn, citizens of the United States, residing at Portland, in the county of Multnomah and State of Gregon, have invented a new and useful Railway- Joint, of which the following is a specification.

Our invention relates to improvements in rail joints, and particularly ,to those joints in which the confronting ends of the two rails are supported in chair, the object of our invention being to provide a rail joint and chair plate of this character, in which the rails are absolutely prevented from any lateral movement and prevented from creeping, a further object being to provide means for more securely holding the iish plates in engagement with the rails, and preventing them from any longitudinal movement.

Our improved rail joint comprises a chair plate u on which the confronting ends of two rai s are set,v this chair plate having inwardly turned flanges. on its longitudinal margins adapted to engage over the angular edges of the usual iish plates, which are placed upon either side of the rails, these angularly turned flanges or edges ci the cha-ir plate being closed at the ends so as to forni A pockets for the reception of the angular flanges of the fish plates, the chair plate be.-

-ing furthermore' provided with studs or other means for engaging with the lease of the rail.

A still further object of our invention is` to rovide a chair plate of this character which may be very easily constructed from heavy sheet metal, our construction not only providing a simple and economical manner of manufacturing the chair plate, but also providing for ax .strengthening ot the niarginal lian es of the plate.

In the rawings:-li`igure l is a perspective view of our improved rail joint, one ci' the rails being removed and the opposed lish plates being in section. Fig. 2 is a transverse section oi liig. l through one oi'f the Studs. F ig. 3 is a plan View of Fig. l, the

"responding parts in all the .figures ofthe 'drawings i Our improved chair comprises a. relatively l l l thick and rigid platef of sheet metal, the side edge-s oi,f which are overturned to torni the singularly disposed inwardly and upwardly heut opposed flanges 3-3, The

chair plate is wide enough to permit a rail hase .ld to he set into the chair plate between the edges oi' the :liauges 5:5 sothat the rail l2 may he easily removed. 'lf he ends of these iianges are closed. by an end lwall 4 that extends down against the bottom olf the chair plate.

lt will be seen from liig. l. that the flanges 3 do not extend along the entire length oi the chair plate 2, and that the chair plate is sulliciently longer. than the flanges to provide end portions 5, formed each with a notch i through which spikes may he driven. 'lhe marginal edge of the plate along the flanges 3 inay the reception ollspikes. the the studs t5 which are alternately set one to the other along the upper face of the plate and have outwardly and downwardly inclined upper faces. rlhe bottoni oi the rail is preferably inade with recesses 6 adapted to engage with the studs, but we do not wish to limit ourselves to this feature.

l t will he seen that when the rail is placed in position on the chair plate, the inclined .tacos or' the stud (i will he in plane with the inclined upper tace oi the rail base, and thus there will be no projecting portion `which will interfere with the close contact between the fish plates 8 and the upper :tace of the base of the rail.

The lish plates S are of ordinary construction and have the angular flanges 9 projecting front the lower margins thcreoif adapted to engage beneath thev inwardly turned lianges 5, these fish plates being of a length sullicient 'to permit them to lit beneath these iianges and between the end walls Il thereof, the lish plates lacing bolted to the rail hy the holts l() having the usual nuts ll. lu place oi" the studs (i, holes lll niaydie formed in the chair plate through which pins -15 may he passed and driven in to the hase oithe rail as shown in Fig. 5, the holes being proton ably elongated lo provide .for expansion and contrzuztion.

As will be seen from Fig. l, the chair piate is preferably made oi.l relatively thick sheet metal, and the end wall flis formed hy turning over the flanges 3 and then press- The upper face oi.'

ing down the end portions 5 firmly on to the' be also notched as at 7 for chair plate is preferably provided withl bottoni ol' the chair plate, the notch 7 being l'ornied by making an opening through the chair plate blanlt, ,this opening heilig placed that when the blank is folded on its' marginal edge, the fold will cross the opening so as to 'oiin'the notch 7. lt will'be seen that not only does the end wall Il so .formed engage with the fish plate 8 to prehave to be relatively thick in order to give any strength, and in practice, the chair plate would have to be cast. ing be more expensive Vthan forming the chaii'plate oli' a metal blank, but it would` Not only would castbe practically impossible to cast the plate?I with the end walls 4 and the pockets formed thereby for holding the fish plates from lmigitndinal movement.

ln addition to the advantages above reierred to, the end Wal-l tends to hold the;

flanges l l'rom any upward movement or disl tortion under strain and, permitting theA chair plate to be made of sheet metal, obviates the chance of the flanges breaking, which would be liable lo occur wlicie the chair plates are cast.

While we have described the portions 5 as being` pressed down before the plate is placed in conjunction with the fish plates S we wish it understood that it would be possible to malte the plate 2 with tlie flanges 3 formed thereon, betere the ends thereof are pressed down. This pressing operation takes place at'ter thechair or bed plate has been placed in position and the fish plates inserted licneath the flanges 3.

lt. will be seen that by having` the flange 9 ot the- Iish plates contained 'within lateral pockets 'tornio/ d on the chair plate, the studs t5 or their equivalents are not absolutely neecssary as the fish plates will hold the rails l'roni any creeping tendency.

lt will be seen that our invention provides a rail chair et' great simplicity both of construction and operation, wherein the rail is held rigidly 'from any sidewise movement but is allowed .longitudinal movement snfli cient to permit contraction and expansion and in which the angular flanges of the ordinary fish plates arc contained within lateral 'pockets which preventlongitudinal movenient of the fish plates and hold them down upon the chair plate.

Our improved railwayvchair is adapted lj'or use with rails and fish plates such as ai'e ordinarily usedon railways to-day, audit does not require any special construction ot' rail or ot fish plate.

While we havedescribed our chair asbeing made of pressed sheet metal we do not wish to loe limited thereto, so we regard this as preferable, as the chair might be made of cast metal without departing from the broad idea of our invention.

From the it'oregoing, it is thought that the construction, ope ation and many rdvan- `tages of the herein described invention will be apparent to those skilled in the art without further description, and it will be under stood that Va rions changes in the size, shape, proportion and minor details ot' construction may be resorted to without departing Yfrom the spiritor sacrificing any ol the advantages of the invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

In a ail joint, a chair. plate having pockets'on bothedges closed at the ends and adapted to receive the `outwardly projecting flanges ot' angular lish plates, said pockets being formed by bending the loi'igitndinal edges of the plate inwardly lro'tn opposite sides.

2. In a rail joint, a chair plate consisting of a single thickness of sheet metal ol such length as to rest aty its endsl on two adjacent ties and having opposed longitudinally' extending inwardly tut ed lateral llanges exteiuling the Al'nll lengtn ot' the plate, and tish plates ha"ing angularoutwardly projecting llanges adapted to extend beneath the said lateral flanges of the chair, each ol saidlateral tlangeshaving a 'all at both ends eX- tending downward to the main bodyof' the plate and adapted to cngageagainst the ends ot' the lisli plates.
