PATRICK H. FARRELL, OF TOLEDO, OHI.`

PAVEMENT. Y

Application lcd February 4, 1919. Serial No. v274;,877.

To aZZ w/iomz't may concern Be itY known'that I, PATRICK H. FARRELL, a citizen of the United Sta'tesof `American residing at Toledo, Lucas County, Ohio, have inventedV new and useful Pavements, of which the following is a specification.-

This invention relates'tofsectional pave- Y ments.

l This invention has'utility when incorporated inremovable sections of block pavement, especially as units adjacent special track work, as in intersections and switches.

VReferring to the drawings z- Fig.. l is a plan view of a track intersection for street railways showing' in places units incorporating features of the invention therewith;

Fig. 2 is a perspective view of a fragmentary unit showing its mounting in relation to a rail;

Fig. 3 is a perspective view in fragment, showing the frame and portions of the pavement section unit; and- Fig. 4 is a detail in Vsection showing the mounting of the unit in position.

The railway track is shown as a rail having` a ball l, upstanding web portion 2, and base flange 3. These rails may be mounted in position in various ways as found desirable for instance, in ties, imbedded in concrete. Y

rllhe pavementunit, in accordance with the invention herewith, may conveniently comprise base supporting girders or planks 4, upon which the platform or base proper 5 may be lixedly mounted as by nails or bolts. YThis platform 5 of aY contour and dimensions desirable `for the insertion of the unit especially between 'track sections, may carry thereon preferably wood paving blocks 6n which may be anchored thereto in spaced relation as to each other by nails 7 toe-nailed or driven at an angle through Vthe block sides into the pavement unit base portion 5.Y These nails may be driven into the block from one'side only.

Integral lugs 8 Vmaintain theV blocks in spaced relation in their grain-up position, while the nailingvof the blocks in one side only permits of the expansion or adjustment of the blocks relatively to each other on the v unit, base or platform. Bolts 9 through the overlapping joist portions 10 of the edgewise disposed'plank members 1l may effectively anchor the frame or boardportions ll in the form of a frame about the blocks 6 on the pavement base 5. This completed frame unit is accordingly iii-position to be installed on the job according to the dimensions of the space to be filled thereby.

In the handling of pavements about track work, the pounding of traffic on the rails has aV Vdecided vtendency to disturb the rail foundations and likewise the pavement. Unequ'al settling and working in of 'moisture with the freezing or expansion tends to distintegrate the pavement, or there is track trouble to be cared `for at various times necessitating access to the track or rails for working with the foundation which involves the taking up of the pavement, and in the usual mode of laying pavements by blocks or sheets, there is destruction or such a waste of material, that this repair problem is one involving?,v` considerable loss of time and material. In the provision of the unit, as herein disclosed, such unit may be readily placed in position and will remain placed as a goed and serviceable pavement unit. In the occasion Yof repair for the base or for -care of the rails, this unit may be removed as a unit, and is not destroyed but may be placed back into position when the repair work or investigation or inspection has had attention.V

This unit has a special utility or value when disposed between rails, but may to advantage be used adjacent rails or the special work, and track units for availing of this advantage of pavement unit removal and thereby avoid destruction of paving Iblocks in gaining access to the track or track ase.

The unit as to its base and frame may conform to the space in which it is to be installed, while it may be mounted upon the foundation supporting the rails and the ties, it is preferably mounted in the position to be carried by the flanges of the rails, especially on the side toward the rails. This means that the unit will be at all times maintainedl in position as to the rail.

In installing'the unit it has sufficient clearance as to the rail that the unit may be placed in position without difiiculty. When installed this slight-space may be filled by crushed stone, or other desired materials, which upon the removal of the unit may be taken out as found convenient.

In practice these units may be made up in the same manner that the track sections are made up and shipped to the job for installation on the pavement base, thereby meaning a minimum of interruption of trafie in the installation of the pavement. For

removal of the units, clearingl outY of a por` basel a track provided with a rail having a flange integral therewith upon which flange .the base rests on at least one side thereof whereby in track use settling and recovery movement of the rail is followed by the blocks only as held assembled on said base, thereby maintaining the blocks against relative disturbance from rail movement.

2. The combination with a group of paving blocks, a plank baseV supporting the blocks, andv a frame on the base maintaining the blocks in a pavement unit with Said base, ot a track provided with a rail having a base flange engaged by the unit baseV whereby tratlie on the rail tending to settle I the rail does not disturb the blocks of the unit as to the rail but such bloeks as as-V seinbled in theunit follow the rail inove-VV ment up and down. v

3. A pavement unit comprising la platform of parallel plank, transverse strips therebelow to hold the plank against relative settling, vwood paving blocks,4 nails anehoi'iiig the block in abutting relation to each other on said platform, and a frame on said base about the blocks rising to the height of the blocks in completing"apavement Vwear against block or frame shifting as to said platform. u

n witness whereof I affix my sig 3'natuie.
