HOWARD L. WADSJVORTH, OF CLEVELAND, OHIO.
SAND CUTTING ANE SCREENXNG :MACHINE Application :filed November 17, 1919. Serial No. 338,655.
To @ZZ .cLo/mt may concern Be it known that I, HOWARD L. NADSH wonri-ii, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ghio, have invented a new and useful improvement in Sand Cutting and Screening Machines, of which the foliowing is a specification; the principle of the invention being herein explained, and the best mode in which l have contemplated applying that principle so as to distinguish it from other inventions.
The present improvements, relating, as indicated to sand-cutting and screening machines, are directed to a machine for use in large foundries where crane service is available, and where the machine may be lifted bodily by a crane and spotted before a pile or windrow of sand which is to be cut. '.lo the acconiplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.
rlhe annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.
ln said annexed drawing Fig. l is a side elevation of my improved machine; Fig. 2 is a plan view thereof; and Fig. 3 is a diagrammatic view on a reduced scale showing the machine when in operation by means of a crane.
in Fig. l there is shown a framework consisting of spaced parallel side members l, uprights 2 and transverse members 3, the entire framework being mounted upon. two
pairs of supporting wheels et and 5. MountV ed at the Jforward end of the machine are two parallel vertical shafts 6 and i', upon which are carried .piders 8 provided with sand-cutting blades or plates 9. These two cutting cylinders are duplicates and the cutting blades are so arranged that they overlap one another, but are never in Contact, as the position of the cutting blades is staggered. lThese sand-cutting cylinders are operated in the direction shown by the arrows in Fig. 2 by means of bevel gears 10 11, l2 and 13, of which the bevel gears 1i and l2 are mounted on the horizontally disposed shaft 14, which is driven through gears l5 and 16, the latter being rotated by means of an electric motor i7, which is carried on the frame of the machine.
The machine is provided with no means for propelling it over the ground, but has an ordinary crane bale 19, by which the entire nachine may be lifted by the cable 20 from a crane cab and carried to the place where it is to be operated. The frame of the machine also provides, at the forward end, aineans for attachment to a tow line 2l, and in F ig. 3 the machine is shown when being towed by a crane. shown a movable crane 22I operabley along spaced rails or guides 23 by the usual means. There is usually of course a crane cab which is operable transversely of the rails 23, but this is not indicated in the figure. The machine is first spottedin front of a pile of sand, which may be either in the form of a windrow 2li, as shown in F ig. 3, or a large heap, and is then towed over the pile of sand at the saine time that the cutting cylinders are operated. These cylinders operate to cut into the sand and take successive slices from the vertical face of the pile, passing the sand between the two cylinders, and then out at the rear of the machine between the side plates 25, which are shown in Figuresk l and 2. `These plates limit the throw of the sand by the cylinders and leave a regular pile of sand after it has been cut. If the machine is being operated to cut a large heap of sand it may first be spotted before one side of the pile, and then towed across this side to cut it, after which it is returned to its original position and used to cut successive portions of the single heap.
Other modes of applyingthe principle of my invention may be employed instead of the one expiained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
l therefore particularly point out and distinctly claim as my invention l. ln a machine of the character described the combination of a rectangular vehicle frame and supporting wheels therefor, sand cutting means mounted on said frame within the same, a crane bail attached to said frame for hoisting the same, and a towing line attached at one end of said frame where- In this, figure there is (ill pendent motive means for driving thesame.
3. In a machine of the character described, the combination of a vehicle'frame and supporting Wheels therefor, and vertically arranged overlapping sand cutting means mounted on said frame Within the sameand` extending the entire Width 'of said frame.
4. In a machine of the character described, the combination of a vehicle frame and supporting Wheels therefor, and sand cutting means ycomprising two rotatable cylinders vertically mounted adjacent to and Within one endof said frame and adapted to overlap one another, said cylinders extending laterally the entire Width of said frame.
5. In a vmachine of the'character described, the combination of a vehicle Jframe and supporting Wheels therefor, sand cutting means comprising tivo rotatable cylinders vertin cally mounted adjacent to and Within one end of said frame, said cylinders extending laterally the entire Width of said frame, and lateral guide means'adapted to feedsand toward said cylinders.
6. In a machine oil the character described, the combination of avehicle frame and supporting Wheels therefor, and sand cutting means mountedv on said frame Within the same and extending the entire width of said frame, said sand cutting means comprising two cooperating vertically mounted bladed cylinders, said cylinders being mounted on parallel axes with their blades arranged to overlap each other.
