. To all whom it may concern:

and State of Texas, have invented certain new and useful Improvements in Road-Surfacin Machines, of which the following is a speci cation.

This invention relates to new and useful improvements in a road surfacing machine. The object of the invention is to provide a machine of the character described which is specially designed for applying a surface of concrete or other similar material to roads and streets, and includes means for spreading the surfacing material over the foundation of the roadway as well as means for tamping said material, so as to give a true and even surface.

A further feature of the invention resides in the provision of a machine of the character described provided with means for smoothing and giving a finished appearance to the edge of the roadway. A still further feature of the invention resides 1n the provision of a flexible apron, whichfollows the tampers and imparts a roughened surface to the finished roadway, so that the concrete or other surfacing material will not harden into a perfectly smooth and slippery surface. With the above and other features in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, one example of which is given in this specification and illustrated in the accompanying drawings, wherein:

Figures 1 and 2 show, respectively, a plan view and a front elevation of the device.

bottom. views, respectively, of the track braces.

Referrin now more particularly to the drawings w ereinlike numerals of reference designate similar parts in each of the figures, the

numerals

1, 1 refer to the end castings of the framework, the op osite ends of each of which are formed int the

legs

2, 2. The free end of these legs are formed into alined bearings wherein the shafts 4: and 4:

respectively, rotate, and, mounted on these shafts are the supporting wheels 5 and 5,

formed to move upon the track 6. The end castings are connected by the side members 7 and 8 preferably formed of channel irons, which, together with the end I-

beams

9, 9 form the frame-work of the machine.

Mounted upon this framework is a suitable motor 10 having the drive-shaft 11.

Fixed upon one end of this shaft is a friction-wheel 12, and upon the other end thereof is the screw-gear 13. Fixed upon the front side of the frame-work are the bearings 14k, 1 1 in which the shaft 15 rotates. Splined upon this shaft is. the friction-wheel 16 which may be brought into and out of contact with the friction-wheel 12 through the eccentric bushing, shown in detail in the instrumen- The frictionwhe'el 1-6 may be shifted toward and from thef'center of the'friction-wheel 12, so as to decrease or increase' the speed of rotation thereof, and may be shifted from one side to the other of said friction-wheel 12 so as to reverse the rotation of said wheel 16, this shifting being accomplished through the instrumentality of thehand-lever 18. A. long counter-shaft 19 is mounted in suitable bearings carried by the respective castings 1, l and is also provided with a central bearing 20 carried by the side member 7. Fixed upon the shaft 15 is a sprocket-wheel 21 and in alin'ement therewith is the sprocketwheel 22 which is fixed upon the shaft 19, and operating over said sprocket-wheels and transmitting rotation from. the former to the latter, is the sprocket-chain- 23. The

legs

2, 2, have the alined bearings 24, 24L- wherein rotate the short shafts 25,25. Fixed upon the respective ends of the counter-shaft 19 are the small sprocket-

wheels

26, 26, in alinement with the large sprocket-wheels 27, 27 which are fixed upon the shaft 25, and operating over these sprocket-wheels and transmitting rotation from the former to the latter are the sprocket-

chains

28, 28. I Each shaft 25 has a small sprocket-wheel29 fixed thereon and in alinement with a large sprocket-wheel 30 which is fixed upon -t e corresponding shaft 4 and operating over these splroocket-wheels and transmitting raj-- tation sprocket-chain 31. A

It is obvious that the traction mechanism hereinbefore described may be operatively connected with and disconnected froin the motor 10 by bringing the friction-wheel 16 into or out of mesh with the friction wheel 12 through the instrumentalityof the hand lever 17 'It is further obvious that 'the speed thereof may be varied and the movement'reversed by shifting said frictiomwheelld back and forth on its shaft 15, through the instrumentality of the hand-lever -lfi'.

The screw-gear 13 is in mesh with a screw-gea'r32 which is fixedonshaft '33, this shaft is rotatable in suitable and has the small sprocketwheel Si lfixed thereon and in alinement with a larger sprocketwheel which is on the shaft 36, A sprocket-chain 37 operates over these s rocket-wheels'and transmits rotation from t e former to the latter.- Loosely. mounted on the shaft36 are'the sprocket-

wheels

38 and 39, which are spaced apart and splined on the shaft 36; "between said

sprocketwhoels

38 and 39 is a double clutch. inember 40 which j is manipulated back and forth s we et-wheel 39 through the sprocketc ain 49.

through the hand-lever 41 in the, Well known manner. vThe inner sides of the

sprocket wheels

38 and 39 are formed into the respective clutch members 42 endsa with which the clutch member O'may be alternatively engaged so as to force the sprocket-

wheels

38 and 39 to rotate; with the shaft 36. Two

counter-shafts 44: and '45 are mounted in suitablebearings carried b the frame-work, the former of which has t e sprocket-wheel whee147 inalinement with the sprocketwheel'39. The sprocket-wheel 46, fixed on the shaft 44 is driven from thesprocket wheel 38 through the sprocket-chain 48, and

the s rocket-wheel 47 f-is driven from the Extending "the full width of the machine is a spreader 50 which is formed of a metallic plate, or runner, whose front edge is turned up at right angles to the road surface. a This spreader is supported by :a plurality of supporting rods 51, to the lower ends of. which the spreader is secured, the upper ends of said rods being hinged to the frame-work at the point 52 and the rods being provided with turn-buckles 53 to permit the vertical adjustment of the spreader. A plurality 'of' connecting rods 54ers pivoted at their for-v ward ends to the spreader and whose other in the formerto the latter is the which is'a transverse metallic plate whose edges are up-turned, as shown in Fig. 3-.

' This plate extends the full width of the mlachine and both the spreader 50 and temper 57 are curved, as shown in Fig. 2 to con cm to the desired curvature of the surface ofthe roadway bein formed. I

to, 'anddepen ng from, the side of f the framework are the vertical 7 bearings 58 through which the tamper-rods 59 operate. The upper endsofthese rods haveeccentric bea 60 on the shaft 44 and as said shaft rotates said rods 59 are reciprocated-vertically, Each of the rods 9is provided with a'turn-buckle' 61 for adustment and the tamperjis supported by said rods, being connected to thelower ends thereof-ithrough a yieldable connection shown indetailinFl Y Shown in 8 is simmer 62 which is formed of: a curved metallic plate and is provided to smooth and I give a uniform curved contour tothe edges of the road surface." ,The "frontjand rear ends of this runner are upwardly curved, as at 63 and 64. vDepend ngfrom'itheres ective

end castings

1,1 are the bearing-

p ates

65, 65 each having a vertical'slot 66, and the run ner 62 has an upstanding flange 67, integral through the slots 66.,andare threaded into the flange 67. These bolts secure, the runners 62 m" positionand permit'the vertical adjustment relative :to the bearings65.

Inthe formation of a road surfaceth'e concrete or' other surfacing material is poured onto the road foundation in front of the machine; As the machine .moves forrial and smooths-them down and spreads the -material uniformly over the 1 roadway. When this is done the clutchqnember 40 is it will be slippery. For the purpose of imarting a rough surface to the finished road have provided a transverse apron 69 therewith. Suitable securing bolts 68 pass ward the oscillating spreader'50 first comes 1 in contact wlththe piles of surfacing matefree portion rests uponthe surface being i mosses formed of heavy coarse fabric or some similar material. The upper edge of this apron is secured to the transverse beam Whose ends are anchored to the rear legs of the

end castings
