PAVEMENT.

. Speoioation of Letters Patent.

Application filed March 2, 1914. Serial No. 822,094.

To all uf/1.0m 'it may concern.'

Be it known that we, 4Louis P. SMITH and JAMES H.v HnAvnnsinn, citizens of the United States of America, residing at ACleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in YPavements; and we do hereby declare the following 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.

This invention' relates 'to new and -useful improvements in the art of paving, and particularly to a new 'and improved means for providing a pavement above the ties and adjacent to the rails of a street railway.

The object of the invention is to provide means for supporting a pavement independently of the ties or rails so that the movement of theties or rails will not disturb or displace the pavement supported by said means.

`With this object in view, and with the intention of securing other advantages which will hereinafter appear, this invention consists in the featuresof construction and combination of parts hereinafter described in the'specication, pointed out in the claims and illustrated in the accompanying drawin nthe accompanying drawings, Figure 1 is a view in section of a pavement embodying our invention. Fig. 2 Vis -a sectionon line 2f2, Fig. l. Fig. 3 is a view similar to Fig. l showing a modification of our invention. Fig. 4 is a section on line 1 -4, Fig. 3. A

Again referring to the drawings, 1 represents the4 road bed and 2 represents the ties which are laid in the customary manner on the said road bed, and the said ties support rails 3 which are arranged thereon and secured thereto in the usual manner. Our improved means comprises a plurality of devices which are the ties at each side of each rail and each -device comprises an inverted U-shaped member or chair having a top' portion7 and leg portions 8. The said leg portions 8 are longer than the dept-h of the tie so that the top member is supported a distance above the tie so that an open space is left between said top.

the top surface of the tie and the member of the device. In the sides of the legs 8 are preferably' formed openings 9, and

arranged over the ends of A S A y extending upwardly fromeach opening is a tube orpipe 10, and the upper end or mouth of said tube is arranged flush with the surface of the pavement. VA- suitable cap 1'1 is provided forclosing the upper end of 4said tube. The object of the opening in the legs 8 is'to permit a tamping bar to be inserted vinto the "space inclosed bythe said chair or supporting device so that the earth around the ends of the ties may be tamped from time to time when 'bar to the said openings so thatthe sai necessary. The tubes` which extend up from said openings proopenings are always accessible and the ties can be tamped without removing any of the paving blocks. Also the tubes provide moans for supplying additional earth or ballast for the ends of the ties. After the devices have been put in position so as to form an arch over t e ends of the ties at each'side of each rail and particularly over the ends of the ties adjacent to the fish-plates which secure the ends of the rails together, the pavement 12is laid on top of the said devices in the usual manner.

The advantages of our improved support. l

ing devices will be readily understood. As is well known, when a car passes. over the rails theties immediately below the car are caused to bow .down by the weight of the car and the outer ends of the ties are caused to lift up above their normal position andV where the paving blocks v of tie ties or upon the ballast which rests directly on 'the ties, the upward movementA of the ends of the ties forces the pavin blocks in the immediate vicinity of the sai ends above the level of therest of the paving. When the ends of the ties settle back to their normal position there is of course nothing to draw the paving blocks back to their original position so they remain above the level 0f the rest of the pavement and are a serious impediment, to .traffic on the street. Now by providing our improved devices for supporting the paving blocks adjacent to the ends of the are supported above and out of contact with the said ties and the open space between the top of each device and the top of the tie affords ample and oftentimes a menace space for the free up-and-down movement of the'ends of the vtie without permitting it' to come in contact with the pavin blocks.

In Figs. 3 and 4 is shown a modi ed form 'face of the plate is preferably corrugated or otberwiseroughened so that horses can get a foothold thereon, and that it may also afford proper traction for self-propelled vehicles. Openings 16 arel provided in the said plate communicatingwith the tubes and caps are provided for closing said open ings. 'Vhat we claim is arranged' thereon and rails arranged on said ties, of means for supporting the pavement adjacent to said ties, said means comprising yso a. device consisting of a chair adapted to arch a tie and form an open space above the tieand below said chair to permit the upward and downward movement of the tie.

. 2. The eombinatioir 4with a road-bed, ties arranged on said road bed and rails carried by said ties, ofnieans for supporting the pavement adjacent to the rails and above the ends of the said ties, said means comprising a series of devices arranged at each side of the rail, each device comprising a horizontally arranged top memberand a pair of downwardly extending legs, the said legs being adapted to straddle theend of ai tie and support the top member of the device a distance above .the tiev leaving a free lspace between the tie and the top member of the device.

3. The combination with a rozd bed, ties arranged on said road bed and rails carried 'by said ities, of means for sup-porting the pavement adjacent to the rails and above the ends of the said ties,- said means comprising'v a series of devices arranged at each side of each rail, each device comprising'a horizontally arrangedv top member and a air of downwardly extending legs, the said egs be- 1. r1`lie combination with a road bed, tiesV ing adapted to straddlethe end of a tie and support the top member of the device a distance above the tie leaving a free space between the tie and the to member of the A device and tamping openings arranged in the sides of said legs.

4. The combination with a road bed, ties arranged on said road .bed and rails carried by said ties, of means for supporting the' pavement adjacent to.the 'rails and above said ties, said means comprising a series 'of devices arranged at each side of each rail and adapted tov arch the ends ofthe said ties, said devices being provided with open- .iiigs in the sides thereof, tubes extending upwardly from said openings, and means for closing the upper end .of said tubes.

5. The combination .with a road bed, ties arrangedon said road bed and rails carried by said ties, of. means for forming a pavement adjacent to the rails and above the ends arranged to extend longitudinally of each rail, legs extending downwardly from said plate and adaptedto support said late a distance above the ends of the ties eaving anopen space between the plate and the ends of t-he fties and 'having the upper surface of the plate flush with the surrounding pavement, openings formed in said plate and covers for closing said openings.

6. A device for supporting.- pavement above ties of a railwayl track consisting of an inverted U-shaped chair comprising a horizontally` arranged member and a pair of downwardly extending legs arranged to -of theties, said means comprising'a plate straddle a tie or a series of ties, the said legs being long enough to support the topv member above and out of Contact with the tie orties.

In testimony whereof, we sign the foregoingspecifieation, in the presenceot' two witnesses.
