RAIL-JOINT..
SPECIFICATION forming part of Letters latent No. 786,636, dated April 4, 1905. Application led January 19, 1905. Serial No. 241,859.
To @ZZ wwnt it mm1/y concern.-
Be it known that I, ADDISON O. FLETCHER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Rail-Joints, of which the followingl is a specification.
rhis invention relates to rail-joints of that class involving' a rail-supporting chair.
It is one of the primary objects of my invention to provide a chair for this use which is simple in construction and which can be readily and inexpensively made.
In designating` the invention as a railjoint, this is simply done 'for convenience, as it will be evident as the nature of the invention is better understood that the chair need not necessarily be used at joints, but may be used at other placesfor example, curves-to prevent dangerous spreading of rails.
The chair in practice is adapted to be connected with a cross-tie in a rigid or immovable manner. Said chair is provided with means for limiting sidewise motion of the rail with which it cooperates. In the adaptation of the invention illustrated I provide on the upper side of the chair flanges against which the side edges of the base of the rail are adapted to abut. These flanges may be of any suitable character. In the present instance they are of a resilient nature and serve to restrict the sidewise motion of the rail to the extent of safety, although they yield sufficiently in a lateral direction to prevent their being snapped from place and also to allow for the proper expansion and contraction of the railchair and cooperating parts without injury thereto. The lateral motion of the rail-limiting' flanges is, as will be evident, almost imperceptible; but it is sufficient to secure the advantages set forth.
To hold the chair against bodily lateral motion, it may be provided with flanges depending from the under side thereof and adapted to be seated in channels in the tie. rIhese lastmentioned flanges are also resilient, so as to augment the effect of the flanges on the upper side of the chair.
Means of a suitable nature, such as wings, on one of the bottom flanges of the chair are provided for restricting endwise notion of said chair or motion in the direction of the length of the rail with which said chair coacts. When wings are provided, they are adapted to engage the side faces of the tie to secure the function set forth.
In the drawings accompanying and forming a part cf this specification I illustrate a form of embodiment of the invention which I will set forth in detail in the following description; but I do not restrict myself to the showing thus made, for certainvariations may be adopted within the scope of my claims. For example, while 'l state that the several flanges hereinbeforc described are resilient, this is not essential, although resiliency is preferred in order to bring about the peculiar results brielly described.
Referring tothe drawings, Figure l is a cross-sectional view of a rail-joint involving my invention. 2 is a perspective view of a portion of a tie and a chair, the two parts being separated in order to more clearly represent theirconstruction. Fig. 3 is a seetional side elevation, the section being taken through the tie and chair. Fig. at is a top plan View of the blank from which the chair is made. Figs. 2 to t, inclusive, are upon an enlarged scale.
Like characters refer to like parts throughout the different views.
In Fig. 3 I have represented two rails, each designated by 2, of familiar construction and which fit end to end in the customary way. These rails 2 are adapted to be sustained by a tie, as 3, the particular construction of which will be hereinafter set forth. The said rails, however, are not directly supported by the tie, but rest directly on a chair, as that denoted in a general way by 4. The chair 4 may be made of any desirable material-for example, heavy sheet metal-which is susceptible to being' swaged. I will denote the blank shown in Fig. 4, from which the chair is made, also by the character Il. The blank is represented as consisting of a'rectangular plate. This plate is doubled on itself along the dotted lines indicated in said Fig. 4 to produce the several flanges shown in Fig. Q in the finished chair. In other words, there are two flanges,

CER
each designated by 5, on the upper side of the chair, and three flanges, as (i and 7, depending from the under side ot the chair, the latter flanges constituting' anchering-flanges. il have used diflerent characters to denote the depending flanges, for the reason that the intermediate one is deeper than the two outside flanges 6, the latter being located. as will be evident, near the side edges of the body of the chair. All the thuiges extend the complete length et the chair. When l speak olE the length oli the chair, l mean that part thereof which extends longitudinally et' the rails 2. The parallel fianges 5, which rise above the upper 'face of the body of the chair, receive between them the bases of' the two adjacent and substantially abutting' rails 2, the under tace of the body being adapted to tit fiatwise and solidly upon the upper flat tace ot the tie. in the tie and extending' downward from the upper 'face thereotl l forni in seine suitable manner the channels 8 and 9, the intermediate channel being' denoted by the character last employed and being deeper than the other channels. The ends of the channels, as will be clearly evident upon an inspection of' Fig. '2, open into the side faces ofl the tie. The flanges 6 and 7 are adapted to be driven into and to snugly lit the several channels 8 and f), the intermediate fiange 7, as will be evident, being arranged to enter the intermediate and deeper groove or channel 9. By drivingthe flanges into the receiving-grooves therefor it will be obvious that when the chair a rests upon the tie it will be eflfectually prevented from bodily lateral motion, although the several flanges hereinbefore described may operate, by reason of theirspring-like term, laterally.
Referring now to the blank shown in Lt, it will be seen that on what might be considered the side edges thereof are two wings, each denoted by l0. Simultaneously with the torina-tion ot the central crease in the blank, which is to produce the downwardly-depending fiange 7 in the linished article, l bend back these wings lO at right angles to the flange 7, so that in the finished article they will assume the relation shown in Fig. 2. As the several flanges 6 and 7 are driven in the corresponding grooves the wings 10 upon the end of the intermediate 'flange will ride down the sidefaces of the tie until the end face ot the chair strikes the tie, indicating that the chair is in proper position. The flanges, as stated, prevent bodily rocking or lateral Inotion of' the chair, while the end wings l0 of the interi'nediate :liang'e etfectually prevent endwise motion ot the said chair. There is no possibility. therefore, of' the latter of itself bodily moving in any direction. In addition to the means illustrated to bring about this result the spikes hereinafter described also aid in securing same and take otl naturally some of the strain put 'upon the holding parts.
Extending across the sidefaces of the rails at their joint are fish-plates, as ll, of ordinary construction, bolts, as 12, also of' seine suitable kind, passing through registering' perforations in the 'webs of' the rails andfish-plates, respectively. The side edges of the bases of the rails and of the fish-plates, it will be seen, bear against the upwardly-extending parallel flanges 5, so that not only do said flanges limit the lateral motion oi the rails, but perform the same oflice with respect to the {ish-plates. To prevent the fisli-plates and rails from upward displacement, l may rely upon spikes, as 13, adapted to be driven into the tie 3 at opposite sides of the chair e, and the heads ot which are adapted to overlie the tops et the lianges 5 and the upper faces of the bases of the fish-plates. rlhe spikes therefore prevent upward displacement of the chair.
It will be evident that the [ianges can each move laterally but slightly upon vibration of' the rails 2; but they etieetually limit dangerous lateral motion of the rails to an extent sufficient to prevent accidents. As they inove laterally, either inward or outward, they impart corresponding motions to the depending anchoring-flanges 6, the vibrations of' the latter being absorbed or taken up by the main or deep intermediate flange 7. Undue outward motion of the side fiange' 5 is prevented by the shanks of' the spikes. The lower edges of the outer branches of` the doubled flanges 5 are located ashort distance above the upper tace of the tie, so that the latter will not affect the proper action of said ffanges.
lt will be seen that the lower edges of the flanges 6 and? are located above the bottoms of? the grooves 8 and 9, by virtue of which free yieldahle motion of said flanges is assured. ln addition te this a space is provided below each flange, into which water may drain and run off away from the tie through the ends of said grooves.
The parallel flanges 5 upon the upper side of the body of the plate or chair, it will be perceived, are perpendicular to said body, so that while I secure the advantages attending the resiliency ofl said 'flanges l also render easy the putting in place ot` the rails. As the fianges are perpendicular to the body or vertical, l can attach the chairs to tie and atterward drop the bases of' the rails into the spaces between the said lianges. The joints therefore can be made with rapidity. The said flanges 5, as will be evident, are integral with the plate and are doubled on themselves, the outer branches of each extending short of the under tace ot' the body et' the chair or plate, which is one simple and advantageous way of securing lateral resiliency in said anges.
Having thus described the invention, what l claim is- 1. A railroad-chair consisting et a plat-e doubled `on itself'l transversely to present a plurality of ascending flanges, each perpendicular to the body of the plate and laterally resilient.
2. A railroad-chair, consisting of a platev transversely doubled on itself to present a plurality of depending flanges and a plurality of ascending flanges, each resilient. i
3. A railroad-chair consisting' of a plate transversely doubled on itself te present three depending` flanges, the intermediate flange being deeper than the other flange, and two ascending' flanges. each flange being' transversely resilient.
l. A railroad-chair comprising a plate having [langes integral therewith on the upper side thereof, said flanges being doubled on themselves to present inner and outer branches, the lower edges cf the outer branches extending short of the under side of the body of the plate.
5. A railroad-chair comprising a plate having flanges on its upper side to receive between them the base of a rail, and a depending an choring-fiange, the latter being provided with means to limit endwise motion of the plate.
6. A railroad-chair, consisting of a plate having langes on its upper side and anchoring-lianges on its under side, one of the lastinentioned flanges being provided with means to prevent endwise motion of the plate.
7. A railroad-chair consisting of a plate transversely doubled on itself to present ascending' flanges and descending flanges, one of the descending flanges being provided with integral wings.
8. The combination of a railroad-tie having a plurality of grooves extending entirely across the same, and a chair provided with depending' flanges to be driven into said grooves, and also provided with ascending flanges to receive between them a rail or rails, one of the depending flanges being provided with means to engage said tie to limit endwise movement of the chair.
