(39 shows the half-inch blocks placed between members 32 and of Fig. 8. The purpose of these blocks is to lower the top of member 32 a half-inch below the top of the planks forming the concrete rail-base form, so that when 33 represents the lateral cross ties of the the anchor-bolts are turned up to receive the cushion, there will be a hole in the concrete below. the end of the bolts so that they can be screwedrlown, if necessary. 70 represents a prepared paper or wood protection, one-eighth of an inch thick, placed around the outside and contiguous sides of anchor-keys and anchor-bolts and extending down to the anchor-link 8, only; the purpose of this is to k'eep the concrete away from this part of the keys and bolts. This protection should be removed when the concrete has set. After the constructionis complete, the race around tll anchor-bolts and anchoriteys should be filled with liquid asphalt.

I provide and specify that a good job of concreting shall be done; that good, hard crushed rock, not larger than two inches in diameter, be used; that the sand be clean and sharp and the Portland cement of good quality and in live condition; that all upper and exposed parts be smooth with no rock showing; when setting the cushion, that it be einbeitlded in liquid cement (Portland and sand).

The lineal. reinforcing

bars

23 and 68 should be two inches less in length than the rails to he used and should be laid with the ends laterally in line; this would leave the abutting ends two inches apart which distance must not be less. The lineal rein forcing bars placed in this way would form sections of concrete of rail lengths. The ends of the sections should come near, but not at, the lineal centers of the rails. The sections should he joined by short pieces of reinforcing bars placed not closer than two inches to any other metal.

The anchor-plates ill, should be placed two inches above the lineal reinforcingbars 23, and not closer. The anchor-bolts 9,

should be formed from three-quarters of an inch round iron or soft steel with lower ends threaded as shown, and, commencing above the tl'n'eauled part, flattened wedge shape and turned at the top from the llattcncd side, shown. The length of the anchor'bolts should be such that when in position clamping the .rails to the concrete rail bases, the lower end will, not extend more than one- (puirter of an inch below the anchor-plate ll.

The anchor-keys ll), should be made of threes uarters of an inch square iron or soft steel with lower 011th; shaped as a wedge and the upper ends turned as shown.

The anchor-links 8, should be formed from three-quarters of an inch square steel with the inside length the width of the base of the rail to be used plus the size of the two anchors and anchor-keys where the pass through it. The ends on the inside should he formed with square angles as shown. These tlllt'l'lOP-llllkS should be either formed from reinforcing bars 7 and 25 or welded thereto. Member 20 is welded to bar 25 and it and the link should lie horizontal and not vertical as shown.

The stirrup of the insulated adjusting rod-coupling (see Fig. 10) should be fiveeighths of an inch thick and not less than two inches wide where the threaded end of rod 6 passes through it. The sides of the stirrup may be tln'ec-eighths of an inch thick and, in width, eased down to threequarters of an inch where they join and are welded to bar (3 on the left. The bolt hole in the right-hand end of the stirrup mustbe fivesixteenths of an inch larger than the threaded end of rod 6 as the insulating thimble "1!) which goes around said rod is one-eighth of an inch thick. The threaded end of rod (3 should pass loosely through the thiinble.

The tie-rod bolt -lshould be made,as shown' in Fig. 2, with a llat place in the threaded end about one-half of an inch long and double the depth of that to whichthe threads are cut. The enlarged ends 13, of the tie-rod that receive the bolt, should have a lateral hole through one side of the same corresponding to the [lat place on its bolt, as shown at the left end of Fig. 2. The purpose of the flat place on the bolt and the hole in the enlarged end of the rod is to receive the nut-lock-wire 15 which is designed to prevent the bolt. working loose.

Reinforcing bars 7 are welded to reint'orcing bars 5 as shown, and these bars 7 and 5 when united, form rods (3. ltods (1 are joined by" the insulated adjusting stirrup rod-coupling shown as Fig. 10 and all combined and united form a single part of the construction and must be so standardized or nnniu'l'acturcd that, by the use of compressible lead washers, onc cighth of an inch thick, between the ends of the tierods and the webs of thc rails. the rails will be in gage and the anchor bolts 9 will stand 1ierpcndicular. It the ends of the tic-rods and the anchor-links 8 are cmistrucled with the proper relation to each other. the slight variations of gage can be adjusted by the nuts on rod 3 of the stirrup coupling.

I would place the combined tie-rods and anchor-links from six feet to eight feet apart on straight track and much closer on the curves-say four feet on a three degree curve. l would place the non-connected anchor-links and reinforcing bars between the connected ones so the rails will be anchored at least every two feet.

The holes near the ends of the rails for the fish-plate bolts should be sulliciently large or elongated to allow for all probable expansion or contraction. The holes in the webs of the rails for the tie-rod bolts 4 should be one-sixteenth of an inch larger than the bolts. If the reinforcing braces shown in Fig. ll are used at the lineal cen ters of the rails there can be little creeping of rails. The spring of the ends of tie-rods will allow for all probable compression of cushion and expansion and contraction of rails. Note, that a sheet metal a i A:

tube 65 is shown and specified. to go around the ends of tie-rods, near the rails, to keep the concrete free from the rods at these points and permit them to spring down or to the side.

To locate the anchor-bolts and anchorkeys quickly and unerringly, I provide and have shown in Fig. 8 parts of a wood frame or form to be used. I of the width and a smallpart of the length. It would be best of full rail length. The lineal parallel pieces 32 should be of the exact width of the bases of the rails to be used and be connected by the lateral mem bers so as to be of the propelgage. The lateral pieces 33 arecut into at the exact center of the same and there hinged together to facilitate moving forward. A shim of wood a half inch thick is placed between members 32 and 33 to drop the anchor-bolts one-half inch lower than they would be if resting on the cushion. Place the center of the frame, where hinged together, in line with the tacks in the center stakesof earth road-bed and the lateral ties 33 on top of the inner planks of concrete rail-base forms and locate the anchor-bolts as shown at 9 and to correspond, lineally, with the tie-rod bolt holes in the webs of the rails to be used, and you cannot, reasonably, get wrong.

For fish-plate bolts I would use a bolt with a lineal U shaped slot in the threaded end of the same and a nut with a hole in one side extending into the threaded center, all adapted to the use of a nut-lock-wire, as shown in Fig. 9. washers one-eighth of an inch thick between the lislrplatcs and the web of the rail. and see that the rails and fish-plates are smooth and free from rust at the places that come in contact witlrthe copper washers. A compressible lead washer is placed under the head of the fish-plate bolt and not under the nut, as shown in Fig. 9.

To install the construction shown in Fig. 1, I provide that the parallel trenches required. be dug ten to fifteen inches deep according to the character of earth road bed and the requirements of the construction; that the bottom of the trenches be well tainped, and, if the road-bed is soft and spongy, that the trenches be dug deeper and the deeper part tilled-in with dry clay or broken stone: that when so dug planks of the proper width be provided in suliicicnt quantity for one day's construction; that half inch holes bored in the planks onehalf inch deep and one and one-half inches from the bottom of the same. and at intervals of four feet; that reinforcing bars 24 be cut to seventeen inch lengths, and placed in the above described holes, after the planks are set in the trenches, and that earth be packed against the bottom of the show only one-half I. would place copper of reinforcing bars 7 and 25,

planks on the outside. The planks provided for the inside of the trenches should be in two widths, one to come up to the bottom and the other to complete the width, same as the outside planks; notches in the upper piece fit over bars 7 and 25. Place braces cut to sixteen inch lengths between the opposing planks, about two inches below the top of the same and out of the way of the anchor bolts. If the planks are wired together, the wires must come below the cushion and not nearer than. two inches to any other metal part of the construction. Line and level up the forms thus made to correspond to grade of earth road-bed and gage of rails. Place the wood frame provided for locating the anchor-bolts in position and place the combined tie-rods and link reinforcing rods in' position as shown in Fig. 1 with the nonconnected links and reinforcing bars located between the connected ones as provided. Give that part of the anchonbolts and anchor-keys that extends below the anchorlinks a coat of melted paraffin or some kind of paint to keep the concrete from adhering to the same and place the one-eighth of an inch protection around the anchor-bolts and keys above the anchor-links-remove this after the concrete has set and preserve for further use. Proceed to fill the forms with concrete (crushed rock, sand and Portland eement) wet enough for a little water to rise to the top; fill up near the bottom of cushion and'let it set sufficiently so that the anchor bolts can be turned up without disturbing the anchor-plates, but do not wait for it to harden or take its final set. Turn up the anchonbolts sufficiently to pass over the cushion and remove the frame and carry it forward to locate additional anchor-bolts. Place the cushion or, preferably, a form for the same, and complete the concrete rail-bases after first placing the conduits in position. When the concrete has set. remove the planks and carry for ward for additional use. Place the cushions if they were not placed when finishing the concrete. Use only thin liquid cement to embed them in. Locate the steel plates 67 that go under the abutting ends of the rails; these plates should only come flush with the top of the cushion. Place the rails on the cushions, adjusting the gage by means of the nuts on rod 6; screw down the anchor bolts; place the fish-plates with the copper washers 37 between them and the webs of the rails and the con'ipressible lead washers under the heads of the fislrplate bolts, turn the nuts up snugly and. insert the nut-lock- 12 Lay the central concrete by the use of the construction train. Have a concrete mixer on the end of a Hat car and materials convenient to the same. Trowel or float the surface of the concrete up smooth and see that all crushed stone is below the surface. The adjustable insulated stirrup rod-coupling connecting rods 6 should be incased in the central concrete without any protection. Good concrete is a non-conductor.

All directions and specifications as to the installation should be strictly followed, if a good and reliable track circuit for the block signal is desired. Metal parts with less than two inches of concrete between them might shunt oil a part of the current.

At the ends of the blocks, I would insulate the abutting ends of the rails by using the best mica insulating cloth between the fish-plates and the rails and the molded mica Washers and thimble shown in Fig. 10 around the fish-plate bolts in place of the copper v: sher provided for the other abutting rail connections.

To install the modified construction shown by Fig. 12, I provide that all things specified for Fig. 1 and applicable to this modified construction, be followed. In this construction there is a special form of rail with the web cut away and the lower part of the head elon ated, by the use of additional metal, an a groove in the same that fits over the upright arm of a continuous railchair and is bolted or riveted thereto. The upright arm is united to and supported by a curved base which rests upon a cushion embedded in. What I call primary concrete 40. The opposing rail-chairs are united and held in gage by combined lateral reiir forcing tie-rods. These rods are shown plain but should be three'quarters of an inch square steel reinforcing bars except at the innenends where they are connected by the adjusting insulated stirrup rod-coupling shown in Fig. 10. The reinforcing and tie-rods 43 pass through holes in the arms of rail-chairs and are riveted thereto, as shown. No metal; other than these rods and the sheet iron tubes 65 around the ends of the same, which tubes should be sutit ciently large at. the rail-chair ends to permit the rods or reinforcing bars to move down and to the side, in case of compression of the cushion or unequal expansion and contraction of rail and rail-chairs; should come closer than two inches to the rail or railchairs or their metal connections. The railchairs and the rails of this modified consbruction should be in two lengths; it one is 30 ft, the other should be 40 ft; the center of the 30 ft. rail should be at the center of the 40 ft. rail-chair and the center of the 4.0 ft. rail at the center of the 30 ft. rail-chair; this would form, practically, a continuous rail. The belt or rivet holes in the railchair should be sulliciently elongated from the center of the rail'chairs toward the ends to allow for unequal expansion of rail and rail-chairs. At the ends 'of signal blocks, the ends of the rails and rail-chairs should coincide and theupright arms of rail-chairs should be connected by a steel plate placed on either side and bolted thereto and insulated as shown in Fig. 1. All the concrcte above the top of cushion 26 and that between the rails is known as secondary concrete and would be laid from the construction train. To install this first modilied construction, proceed in a similar manner as in the first construction until the cushion is placed, not neglecting to place the shorter reinforcing bars 4-1. and 45; then set the rail-chairs on the cushion; place the sheet iron tubcs 5 around bars 43 and insert the ends of the bars in the rivet holes in the arms of rail-chairs and rivet the same thereto; place. the rails on the.up right arms of railcha-irs and bolt or rivet the same thereto; it rivets are used they should be only slightly hannncred down so that they could be readily punched out shonld'a change of rails, from any cause, he required. Adjust the gage of rails by the nuts on the ends ol the tie-rods. Place the conduits as shown and form the lineal and the lateral drainage channels same. The rail-chairs must have a heavy coat of asphalt paint, applied hot, before the secondary con crete is laid. Provide for disposing of the drainage water, collected in the center of the track, by placing metal tubes if), made of thin shcct iron, at suitable intervals and incase the same in concrete as shown.

Install the modified form of construction shown in Fig. 14 as the drawing'and de-. scription of the same would indicate; reference being had to provisions for the installation o'lithe modification shown in Fig. 12.

In the second modified construction, as shown by Fig. 15, we have a concrete construction similar to that shown in Fig. 12 except that the draftsman ne le ted to provide for drainage. I would specify that the concrete at the rails be brought up within one-half inch of the head of the rail and lineal drainage channels formed as in Fig. 12; and that these lineal channels. be connectcd, at suitable intervals, by lateral channels and that the drainage water be disposed of through sheet metal drainage pipe incased in concrete as shown in Fig. 12. In this construction we have another special form of rail with the base cut away and formed into a curved, continuous cap upon which the web of rail rests and which curved .cap rests upon a cushion inclosed within a rail-shoe composed of two curved steel plates 61 connected at the bottom by the metal cleats 62 and havingthe Web of the rail bolted between the vertical parts of the curved steel plates. The tie-rod 56 used in this construction should be connected in the center by the insulated adjusting stirrup rod-coupling shown in Fig. 10. These tierods should be placed at reasonable intervals and bolts, similar to those shown at 10 in Fig. 12 used between the tie-rod bolts 4: at intervals of near two feet. The bolt holes in the web of the rail should be larger than the bolts to allow for compression, contraction and expansion. Install in a manner similar to that provided for the other constructions,

Fig. 16 represents this last modified principal construction adapted to street railway construction when the streets are pated with an material having a concrete base. I would install this street railway construc tion in a manner similar to that provided for the other constructions.

The cushion 26 may be composed of the following materials :The cushion for Fig.

1'- where the present form of rail is used, would be more exposed to changes of temperature than the cushions in the other constructions and should be composed:

First: Of light, porous wood free from knots or hard pitchy spots and should be first kiln dried and then immersed in crude oil or oil residuum of an asphalt base,while hot. It should be boiled in the oil or residuum or the same should be forced into the cells of the wood by pressure. A cushion thus prepared would last indefinitely, at least more than twice as long as the average tie as now treated.

Second: The best rock asphalt 25%, crude oil of an asphalt base 3%, sand 45%, Portland cement 22% and line dry sawdust 5%. Add the oil to the asphalt and heat the same until the asphalt is melted, then add the other ingredients. Keep very hot and mix thoroughly. Press, under heavy ressure, into a mbld of the proper shape while hot. Place paper in the mold so that the cushion can be turned out or have a mold that can be opened.

Third: Asphalt 20%, crude oil of an asphalt base 2%, gasolene 10%, sand 40%, Portland cement 18% and sawdust (fine and dry) 10%. This last composition of materials is prepared cold. Break the rock asphalt into small pieces about the size of grains of corn or smaller, add the oil and gasolene and after standing" some ten or twelve hours agitate until you have a smooth mixture with all the asphalt dissolved. Now add the otheringredients specified and mix all thoroughly. Let the completed mixture stand until the larger part of the gasolene has evaporated, but not till too dry to adhere together firmly under pressure. When in the proper condition press under heavy pressure in a mold of the proper form.

The asphalt mixtures should last indefinitely and would, for years at least, provide greater resiliency than the wood cushion. The purpose of the Portland cement is to toughen the mixture, it does not harden it. The purpose of the resiliency particularly in cold Weather and in hot weather to absorb the lighter or oily particles of the asphalt and retard its softening tendency when exposed to heat.

For the cushiensin the modified construction, a cushion substantially the same as the finishing coat of the best asphalt paving may be used, or preferably, the third composition as above.
