TIE-PLATE MACHINE.

SPECIFICATION forming part of Letters Patent No. 712,167, dated October 28, 1902. Application filed August 14, 1901. Serial No. 72,037. (No model.)

To all whom, it may concern:

Be it known that I, FREDERICK W. Wool), a citizen of the United States, residing in the city of Baltimore, State of Maryland, have invented a certain newand useful Improvement in Tie-Plate Machines; and I declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates generally to a machine for applying tie-plates to railroad-ties, and more particularly to a machine for this purpose which will simultaneously secure the tie-plates toa tie at a predetermined distance apart to conform to the gage of the railroad.

In the construction of railroads the tie plates are ordinarily secured to a tie separately, which necessitates the applying of one plate to the tie and then the location of the second plate by accurately measuring the distance from the first, in order that the rails when fastened to the plates may be spaced apart the requisite distance.

The object of my invention is to provide a machine which will perform at one operation the several steps incident to properly applying the tie-plates to a tie.

A further object of my invention is to provide a machine of the character referred to which will simultaneously apply the tie-plates to a tie at the desired distance apart, which will properly position the tie with respect to the tie-plates, and which will also securely hold the tie, and thereby prevent its displacement while the plates are being applied thereto.

The invention will be more fully described hereinafter, with reference to the accompanying drawings, in which the same is illustrated as embodied in a convenient and practical form, and in which- Figure 1 is a perspective View of the complete machine; Fig. 2, a longitudinal seclional view through the center of the machine; Fig. 3, an end elevational view of the machine looking from the right in Fig. 1 and from the left in Fig. 2; and Fig. 1, a cross-sectional View taken on line 4 4, Fig. 2, looking in the direction of the arrows.

- The same reference characters are used to indicate the same parts in the several figures of the drawings.

My invention is illustrated as embodied in a machine consisting, essentially, in a bedplate upon which are adjustably secured cylinders the pistons within which are actuated by fiuid-pressu re, and thereby simultaneously move abutments upon which the tie-plates and tie are placed, the latter being forced into engagement with fixed abutments,whereby the tie-plates and ties are subjected to a compression in order to apply the plates to the ties at the desired distance apart. The tie is properly positioned relative to the tieplates and is prevented from lateral displacement while the tie-plates are being secured thereto.

Referring more particularly to the drawin gs, reference-letterA indicates a base-plate, which may be located upon a railroad-car or upon any other desired or suitable support. Guides A and A are provided upon the upper surface of the bed-plate and are arranged parallel at any desired distance apart. Fluidpressure cylinders B and B are supported upon bed-plate A and are provided with projections b and b which engage the parallel guides A and A whereby the positions of the cylinders may be adjusted. Within the cylinders B and B are pistons C and 0 respectively, which are provided with. pistonrods 0 and 0 extending through the cylintier-heads E and E The pistons are provided with packing and are also provided with projecting pins 0, which engage corresponding-shaped recesses e in the cylinder-heads E and E The cylinder-heads are secured to the cylinders in any desired manneras, for instance, by bolts extending through the heads and through outwardly projecting flanges on the upper ends of the cylinders, as shown, forinstance, in Fig. l. 7

The cylinders B and B are provided with outwardly-projecting lugs B and B respectively, through which pass posts J and J these posts being preferably four in number, projecting from each of the cylinders. The

upper ends of the posts support cross-heads D and D respectively, by means of circular flanges D and D, located at the corners of and formed integrally with the cross-heads, the upper ends of the posts J and J passing through the openings in D and D and being secured by suitable means-such, for instance, as nuts (1 and d Depending from the cross-heads are platens H and H which are secured to the cross-heads in any suitable manner, preferably, however, so as to have a slight oscillatory movement relative to the cross-heads. Bolts H, provided with nuts h, are shown as passing through the platens H and H and also through the centers of the cross-heads D and D The heads of the bolts are located in recesses formed in the platens, which they engage through interposed washers. The openings through the platens are slightly larger in diameter than the bolts H, and the points of contact between the platens and the cross-heads are spherical,whereby the slight oscillatory movement above referred to is permitted.

The ends of the piston-rods c and c are provided with heads F and F secured thereto by any suitable meanssuch, for instance, as dowel-pins f. Platens G and G are secured to the heads, respectively, by suitable means, which preferably consist in universal joints formed by a spherical engaging surface through which pass bolts g, the heads of which are seated in recesses g and g formed in the surface of the platens G and G Washers may be interposed between the heads of the bolts g and the recesses in which they are located. The openings through the platens G and G through which the bolts g pass are slightly larger in diameter than the bolts, thereby permitting universal oscillation of the platen, such oscillation, however, being limited by pins F, projecting from the upper faces of the heads F and F and entering the recesses formed in the under surface of the platens G and G The cylinders B and B are provided with projecting lugs l and Z within which is journaled a shaft L. A crank M and lever M project upwardly from the opposite ends of the shaft L, to which are secured pairs of links N and N respectively, the opposite ends of such links being secured to one of a pair of levers O and 0 the latter being 0peratively connected at their adjacent ends by a link 0. The links 0 and O are arranged in two pairs and are pivotally supported at points 0 and 0 respectively, upon portions projecting from each of the cylinder-heads E and E A lever M is rigidly secured to the shaft L and serves as a means for rotating such shaft, and with it the crank M, rigidly secured thereto. The lever M is loosely supported upon the shaft L through the collar m surrounding said shaft, and is extended beyond its point of connection with the links N to afford means for operating the pair of stance, by split collars k levers 0' and O pivoted upon the cylinderhead E through the intervening pair of links N connected to the lever O.

The cylinder B is provided with projections q, within which is journaled a shaft Q. The opposite ends of such shaft Q are provided with crank-arms Q and Q the former of which is connected bya pair of links R with a hand-lever R, the lower end of which is supported upon a projection 0", extending from the base of the cylinder B The crank-arm Q is connected by means of a pair of links q with a lever P, the end of which is pivotally secured between lugs 19, projecting from the cylinder-head E The end of the lever P opposite to its pivotal support is preferably bent at substantially a right angle and is provided with lateral projecting portions P.

Parallel rods K extend between the posts J being suitably secured thereto-as, for in- Similar parallel rods K" extend between pairs of the posts J, to which they are secured at their ends by suitable meansas, for instance, split collars 76.

The cylinders B and B are provided with openings, preferably screw-threaded, at and 00 within which are secured the opposite ends of a pipe X the latter being connected by a suitable coupling with a pipe X, which communicates with the interior of a valve-chamber V. The valve-chamber is provided with an exhaust-conduit Y and with a supply-conduit X, which communicates with any desired source of pressureas, for instance, a steamboiler. Within the valve-casing is a valve of any desired construction for controlling the communication of the pipe X with either the supply-conduit X or the exhaust-conduit Y. This controlling-valve may be operated by connecting a stem 1;, which projects above the casing, with a handle W. To permit the relative adjustment of the cylinders B and B, the pipe X, which is connected at 0: and m to the cylinders, may be flexible or may be rendered adjustable in length by means of an extended coupling-sleeve X thereby allowing the pipe X to be lengthened or shortened to correspond to the adjusted distance be tween the cylinders B and B In order to permit the escape of the air above the pistons when they are moved by the admission of fluid-pressure to the cylinders, ports Z and Z are provided.

The operation of my invention is as follows: The tie-plates s and s are placed upon the platens G and G with their flanges, which are adapted to be forced into the tie, extending upwardly. The tie T is then placed above the tie-plates, it being supported at its opposite ends by the pairs of bars K and K respectively. The hand-lever R is then swung upon its pivot and through the connecting-links R and the crank-arm Q oscillates the crank Q, which in turn swings the lever P on its pivotal point through the ders.

ens G and G upon which the tie-plates s and intervening connecting-links g and crank-' arm Q The lateral projections P on the end of the lever P are brought into contact with the adjacent end of the tie, thereby forcing the latter lengthwise to the position desired relative to the tie-plates. The levers M and M are then oscillated. The former rotates the shaft L, and with it the crank-arm M. The pairs of links N and N connected, respectively, to the crank-arm M and the lever M swing the levers O of each of the pairs of clutch-levers about their pivotal points 0', the second levers O of each pair being simultaneously swung about their piv-' ots 0 by means of the interposed links 0, one of which connects the adjacent ends of the clutch-levers forming each pair thereof, as clearly indicated in Fig. 4. The pairs of clutch-levers O and O are consequently brought into contact with the opposite sides of the tie at points adjacent to the tie-plates, and thereby retain the tie in any desired position and prevent its displacement during the subsequent operation of the machine. By providing separate operating means for each pair of clutch-levers O and O the tie, although of irregular width, will be securely held in place, as the clutch-levers accommodate themselves to the width of the tie at the points of their engagement therewith. The controlling-valve is then operated by means of the handle W and valve-stem u, so as to connect the supply-conduit X with the pipe X, whereby fluid-pressure is admitted to the cylinders B and B through the intervening pipe X and its connections wit-h the pipe X and with the openings x and r in the cylinders, as clearly shown in Fig. 2. The pistons O and C are forced upwardly bythe admission of the fluid-pressure to the cylin- The pistons carry with them the plat- 8 have been placed, and when the tie-plates come into contact with the tie the latter is also carried upwardly into contact with the platens H and H which are supported by the cross-heads D and D The tie-plates and tie are thereby subjected to a compression which forces the projecting flanges on the tie-plates into the tie. The pistons G and O are prevented from rotating by the engagement of pins 0 with the recesses e in the cylinder-heads, thereby preventing the tieplates from being rotated during their upward movement when carried by the platens G and G The universal or oscillatory connections between the movable platens G and G and the heads F and F on the ends of the piston-rods, and also the universal or oscillatory connections between the fixed platens or abutments H and H and the crossheads D and D ,'permit sufficient movement of the platens to accommodate any inequalities or irregularity in the thickness of the ties. When the upward movement of the pistons in the cylinders has effected the application of the tie-plates to the ties, the controlling-valve is operated so as to disconnect the pipe X from the supply-conduit X and connect the former with the exhaustcondnit Y, thereby permitting the escape of the fluidpressure from the cylinders, and consequently allowing the pistons to return to their normal position, as shown in Fig. 2, for

instance. 1

It should be noted that in my machine the position of the cylinders upon the bed-plate may be adjusted, thereby changing the dis tance between the platens upon which the tie-plates are supported. The machine therefore is capable of fixing the tie-plates to a tie at any desired distance apart to conform to the gage of the railroad. It should also be noted that the distance of the tie-plate from one end of the tie is regulated by the operation of the lever P, as above described, and also that the tie during the operation of applying the tie-plates thereto is retained in the desired position with respect to the tieplates by means of the pairs of clutch-levers- O and 0 While I have described more or less precisely the details of construction,I do not wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents, as circumstances may suggest or render expedient, without departing from the spirit of my invention.
