Application filed June 15, 1920. Serial No. 389,101.
To all whom it may concern:
Be it known that I, EDWARD P. LANG- WORTHY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Mold- Material-Projecting Mach1nes, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of pro ect above the belt or conveyor so that the this specification. My invention relates to lmprovements in devices for projecting mold material into One of the objects ofmy lnvention 1s to provide an apparatus for pro ectmg the mold material into molds in the form of small compact wads projected at a high velocity whereby the sand wlll be properly packed into the mold.
Another object of my invention is to provide an apparatus of the above character which will project the sand with the least spreadin or throwing of loose sand and which Wlll require the minimum power for operation.
For the purpose of disclosmg my nvention I have illustrated one embodiment thereof in the accompanying drawings in which:
Fig. 1 is an elevation showing my machine in operative position.
Fig. 2 is a sectional view taken on the line 22 of Fig. 1.
Fig. 3 is a plan view of the machine.
Fig. 4 is a transverse sectional view of the rotary projector.
Fig. 5 is a side elevatlon with the cover portion broken away to show the construction of the rotor; and
Fig.6 is a perspective view of one of the blades.
In the embodiment illustrated, I provide a mast or support 1 which may be sultably braced as by braces 2. At the top of this mast there is an I-beam 3 having at its rear end bolted thereto a pair of arms 4 which in turn are secured to a bifurcated support 5 extending from a sleeve 6 pivotally mounted on thepost 1. At the forward end of the I-beam 3 there is likewise provided a bifurcated extension 7. Between'the ends of the extension 7 there is mounted ,a pulley orbelt conveyor pre erably forms the bottom 1 of a trough formed by a pair of side mem- ;bers 12 secured by suitable braces or supports 13 to the I-beam. These side members contents thereof will not be spilled off on the side.- The forward end of the arm is held in horizontal osition b means of suitable braces 14 whic are pre erably connected to the bifurcated arms 7 at the point where the pulley 8 is journaled. The arm 3, due to its sleeve connection with the mast, may be swung in a horizontal plane, the braces 14 being secured to a rotating sleeve 14 to permit the entire structure to swing.
At the outer end of the arm 3 is mounted a depending link member 16 from which depends a swinging frame. This frame preferably consists, as shown, of a vertical arm 17 and horizontal tric motor 19 is secure on the platform and the top of the motor frame is secured by a I illustrated, particularly in Figs. 4 and -5, this projector comprises a dished wheel 21 mounted on a. shaft 22, journaled in the lower end of the arm 17. A belt 23, passing over a pulley 24 on the shaft 22 and a pulley 25 onthe shaft of the motor 19 serves to drive the projector in a counter clock-wise direction with the parts in position as illustrated in Fig. 5. The periphery of the wheel is formed wlth a straight portion 26 and at suitable intervals on the inner face of the wheel are formed a series of radial ribs 27 which are obliquely dis osed and which preferably increase in wi th toward the periphery' of the wheel. Transversely extending from the straight portion 26 of thelarly disposed'flange 29 through which be ts latform 18. An election u on the fiange 26. A stationary cover 31 enc oses the periphery of the wheel and I this cover is provided with sides 32 and 33 range of movement if desired.
which extend artially down on each side of the wheel su stantially the height of the paddles so that that ortion of the wheel is snugly and complete y enclosed. This casing is preferably made in two sections to permit its being assembled on the wheel and is secured to the arm 17 by means of suitable braces 34. This casing, as is shown in Fig. 5, is open as at 35 and tangentially with the wheel, the cover is extended to form vertical walls 36 and 37, providing a spout through which the mold material may be projected.
Secured over the front face of the casing is a cover plate 38 which together with the casing encloses the wheel. This cover plate 38 is provided with an aperture 39 through which projects the lower end of a chute 40, the upper end of which is immediately below the outer end of the conveyor belt 11 to receive the material therefrom. This chute is secured in position by any suitable brace, as for instance, a brace 41, on the horizontal arm 17. It is thus seen that the chute and head are so mounted that the lower end of the chute moves in whichever direction the projector moves and that the projector, due to the universal joint 20 may be swung to any position to direct the material into different parts of the mold. Furthermore, due
to the fact that the arm 3 is pivoted at 6,'
this arm can also be swung to permit a wider In operation the material is deposited on the rear end of the traveling belt 11 by any suitable apparatus, such, for instance, as a chute leadingfrom a hopper or a chute leading from a conveyor, or in any other desired manner. The material is preferably fed at a definite rate and is carried forward by the conveyor and deposited into the chute 40 by which it is conveyed to the rotatin projector and delivered to the projector su stantially at the center of the dished wheel, therefore the stream or column of sand is not struck as hard a blow by the blades or ribs 27 as it would be if it were fed transversely to the blades 28. The sand being fed at or near the center of the rotary projecting wheel is picked up and b centrifugal force thrown outwardly towar the casing 31, the ribs 27 aiding in this operation although even if the ribs 27 are left out, the friction of the side of the wheel would have the same tendency to throw the sand out toward the periphery of the wheel. As the sand is proected by centrifugal force toward the peripheig of the wheel, it is also carried aroun at the periphery by the paddles 28, being held from further centrifugal projection by the casing 31 and compacted into wads against the paddles or blades and the casing being finally projected downwardly through this opening 35.
Having thus described my invention, what I claim as new and desire to obtain by Letters Patent is:
