MCHINE FOR HANDLING PAVING MATERIAL.

To all whom t may concern.'

Be it known that I, WALTERA. TRINLER, a citizen of the United States,.residing at Rutherford, in the county of ,Bergen and State of New Jersey, have invented certain new and useful Improvements in Machines for Handling Paving Material, of which the following is a specification.

The present invention relates to a machine arranged and constructed for the purpose of handling the blocks or bricks used in the construction of pavements.

The objects of thepinvention are, to` provide an endless carrier adapted to receive and transport paving bricks or blocks, which? endless carrier will move in a horizontal plane and will remain, throughout its length, a uniform height from the ground level, which height will be proper to allow the workmen to remove the bricks from the conveyer while in the stooping position assumed in pavement laying; vto provide suitable means for driving the conveyer, and toy allow a reversal of the direction of travel of the conveyer when desired; to provide a trackway upon which the conveyer travels; to provide tractor means for the 'framework; to provide motor power for operating said tractor means; to providemeans permitting of a reversing of the direction of movement of the tractor means; and also to provide means permitting the tractormeans on one side to be driven independently of the tractor means on the'other side and thus effect a steering of the machine.

The invention further consists in the features of construction and combination of parts hereinafter described andv claimed.

relates, in the laying of pavements it is customary to pile the paving bricks or blocks `Specification of Letters Patent.

In the art to which the present invention- Patented FebQlZ? 1917.

Application filed April 19, 1916. Serial No. 92,162.

vnipulated, and can be built sufficiently cheap to warrant its adoption by the contractor. Referring now to the drawings, the machine lcomprises a framewo-rk 6, which, as shown, 'consistsof an upper section 7 and a lower' section 8. Each of these sections is of angle-formation, as will be seen more clearly from Fig. 3. lThe upper section has the angled portion 9 turned inward to form a frame along the inner edge of said section. The lower section has the angled portion 10 turned outward to form a trackway for the conveyer, which will be more fully hereinafter described.V TheV two sections are connected vtogether in any suitable manner, as, for instance, plates 1l.

Still referring to Fig. 3, it will be seen that the lower portion of this framework is open so that in fact the framework is of hollow constructionV and open at its lower end. The function of this will more fully hereinafter appear. Suitable crossisupports 12'are provided, and to these cross supports aremounted wheels 13, which are ofa nature todrive a caterpillar chain 14. There are two of these caterpillar tractor wheels provided, one on each side, as will be seen from Fig. l. I prefer the use of this caterpillar construction because ofthe fact that it givesl abroad base for the tractor .members, so that they do not depress or cut into the previously laid pavement.

yBy making the framework so that it is open at its lower end, I .can extend the tractor membersup inside of the frame. This allows the frame to be placed close to the ground, and will bring the conveyer at a suitable distance-probably about a foot from the ground vlinewhich is necessary to allow the workmen to readily and quickly removethe blocks from the conveyer without moving from the stooped position assumed iny pavement laying.

Upon the upper surface of the framel I provide, in the construction shown, covering plates 15. The frame 6 as a Whole is made in two parts, one of which is designated by the numeral 16, and the other by the numeral 17; and these parts Vare joined together, as shown, by a `bolted illerblock 18.

By loosening the bolts -of this filler block,v

the parts of the frame can be .moved with respect to one another so as to lengthen the frame orV shorten it, in correspondence to the width of the street being paved.

I employ, inthe construction shown, a gas vmotor 19 for driving the tractor members. The drive shaft of the motor is provided with a pinion 20 meshing with'a gear 21, which drives a cross shaft 22. This cross shaft carries a pinion 23 moved in and out of driving engagement by means of a suitable clutch 24. The pinion 23 meshes with agear 25 on a driven shaft 26; and on this driven shaft is a sprocket 27 for driving a chain 28 leading to the tractor on lone side. Also on the shaft 26 is a sprocket 29 driving a similar chain 28 to actuate the tractor on the opposite side.

The sprocket 27 is thrown in and out of driving relation by means of a clutch 30, and the sprocket 29 is thrown in and out of driving relation by a clutch 31. By actuating the clutch 24, the entire driving connection `to both tractors is interrupted and the machine remains stationary, although the engine is running. When both

clutches

30 and 31 are thrown into engagement, both tractor members are driven and the entire machine moved straight forward or back. However, if theV clutch 30, for instance, is thrown into engagement and the clutch 31 out of engagement, then only the tractor driven by the sprocket 27 will be actuated, which will effect a turning vof the machine in one direction. If the clutch 31 is thrown in and the clutch 30 out, the machine will then be driven in the opposite directionV through the actuation of only theV tractor member associated with the sprocket 29. Of course, the particular means of driving the tractors is subject to variation and modification.

Mounted idly upon the shaft 22 is a gear 32 controlled by a clutch 33. This gear 32 meshes with a gear 34, which is secured to a shaft 34a having on its other end a gear 35, which meshes with the gear 25, and by vthis means a reverse motionV is imparted Vto the shaft 26 to effect a reverse drive of the tractors.

The conveyer comprises a link belt or chain 36 of suitable construction, joined to which are a plurality ofplates 37 in overlapped relation. These plates are mounted so that they pivot about the pins 38, which connect them to the chains. This permits the conveyer to turn around the corners of the frame. A U-shaped vmember 39 is secured to the plates and to the chain, which U-'shaped member serves as a mounting for a roller 40 that travels on the flange 10 of the lower section of the frame. This flange, therefore, constitutes a trackway for the conveyer, which prevents the conveyer from sagging during operation.

By making ltheconveyer of sectional formation, the length of it can be increased or decreased in accordance with the shortening or lengthening of the frame of the machine. The conveyer is driven by a series of sprockets 41, which are mounted in bearings 42 within the frame. As shown, there is one of these sprockets at each corner of the frame, and the sprocket closest to the motor 19 (see Fig. 2) is driven by means of a bevel gear 43 and bevel pinions 44 on a sleeve 44a which is mounted on the shaft 22. By means of a lever 45, the position of the pinions 44 can be shifted tobring one or the other into engagement with the gear 43. This enables a reversal to be made in the direction of travel of the conveyer. An adjusting mechanism 46 is shown. for one of the sprockets to allow it to be moved in and out to take care of the slack which may develop in the conveyer.

From the foregoing, it will be apparent that the machine is cheap and simple of construction for the work intended, and contains no involved nor complicated parts that would be liable -to become disarranged and place the machine out of use. Also the bricks or blocks are delivered close to the ground within handy reach of the workmen, and-this is accomplished lby mechanism which can be produced cheap enough to make it practical of employment by the ordinary contractor.

'In' use, the machine is placed on the previously `laid pavement and moved along as the work progresses. The sides of the machine are brought .close -enough'to the pile of bricks or blocks along the street to enable themto be placed on the conveyer of the machine, .by which they are carried into position to be lifted olf by theworkmen and placed in position@ rEhe various controlling Lmechanisms allow the machine to be moved forward or backward, or around corners, and permit -fthe conveyer to be moved clockwise or counter-clockwise, as desired.
