UNITED STATES WARREN D. WILLIAMS, OF ERIE, PENNSYLVANIA.
STEAM SHOVEL.
Application filed January 12, 1922. Serial No. 528,789.
and useful Improvements in Steam Shovels and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.
I My invention relates to steam shovels and has for its object the providing of suitable mechanism for securing the dipper to the dipper-stick in such a manner that the dipper can be used to work towards the'machine in the manner of a hoe, or away from the machine in the manner of a shovel; thereby making the ordinary steam shovel apparatus adapted to be used in either manner.
The features of my invention are hereinafter fully set forth and pointed out and are illustrated in the accompanying drawings, in which:
Figure 1, is a side elevation of a steam shovel embodying my invention, part of the housing thereof being broken away.
Figure 2, is a side elevation of a fragment of the mechanism shown in Fig. 1, with the dipper reversed. I
Figure 3, is an enlarged side elevation of my improved dipper mechanism.
Figure 4, is a rear elevation of the same.
Figure 5, is an edgewise View of the lower portion of the dipper-stick.
In these drawings Alindicates the house enclosing the power plant of the machine; B indicates the shovel boom, the lower end of which is pivoted by means of the pivot Z) upon the casting A secured in the frame of the housing A; said boom being maintained in its proper position by means of stay rods B. The boom B is constructed in the usual manner, of two parts spaced apart. Upon the boom B is secured the usual crowding engine C, which operates the usual crowding pinion C"; D indicates the dipperstick which is constructed in the usual manner, of two pieces, as shown in Figs. 4 and 5, and is provided with rack teeth (Z which intermesh with the crowding inion C; the lower end of this dipper-stic is provided with a casting D which has bifurcated arms pin E passin d between which'arms the pulley D is placed for the purpose hereinafter explained.
On the outer face of this dipper-stick I place metal plates E E which are secured thereon by means of pins E and E the through the pulley D, and upon which said pulley revolves. The plates E are provided at the lower ends with lateral arms a e which have holes through their lower extremities The upper ends of the plates E are provided with a plurality of holese", by means of which the plates E E may be secured upon the dipper-stick at such angle as may be desired, by means of the 'pin E F indicates the dipper, upon the upper side of which is secured a metal plate F, which isprovided with ears 7 at its four corners, through which ears holes f are provided, which will co-incide with the holes in the ends of the lateral arms 6 of the plates E. 1
The plate F is also provided with an arm .F the end of which is bifurcated as shown in Fig. 4, to receive the looped end of a drag-line cable G, which is secured therein by means of a pin f and upon this pin f is placed a bell crank lever H for operating the latch 71. of the dipper door H, one arm of said bell crank lever being connected with said latch by means of link 11.; h indicates a dumping cord secured to the bell crank leverH which extends thence to the housing A; J indicates a pin passing through the front ears 7 on the plate F to secure .the dipper to the front arms e of the plates E;
-K indicates straps pivoted =.upon the lower pin E, and to the upper ends ofthe straps K a blockK of the lifting tackle is secured, through which the lifting lcable K operates over the pulley B in the upper end of the v boom B in the usual manner.
The drag-line cable G extends from the arm F over the pulley D in the dipper-stick and therefrom to the usual drum mechanism (not shown) in the power house A. In operation, when the dipper is lowered by the lifting cable K and extended by the operation of the crowding engine C to the position shown by full lines in Fig. 1 power is applied to the drag-line cable d which causes the dipper F to tip its operating ed e down, and the continued strain on the cab e G, (the lifting cable K being slackened), draws the dipper F toward the machine; when the dipper-stick has swung to a substantially perpendicular position the crowdas my nevasae ing engine is operated to lift the dipper upward, the drag-line being now slackened, and the slack in the lifting cable being taken up. As the dipper-is only secured to the plates 5' E at its front end, the gravity of the dipper, and the material in it cause the rear end of the dipper to swing below the plane of its front end, so that'the material within the dipper will not be spilled out. The lifting cable K and the crowding engine C are now caused to co-operate to carry the dipper upward and outward so that the same can be swung to the desired position for dumping the dipper. This dumping operation can now 5 be accomplished by the shovel operator pullthe latch of the door H, or he can cause the '2 line G is disconnected from the arm F the dumping cord is disengaged from the bell crank lever H, the in J is removed, and the dipper F thereby disengaged, is reversed and the pin J passed through the holes 7 in the 0 ears of the plate F, and a pin J passed through the ears 7 at the front end of the dipper F, so that the dipper F and dipper stick D 'are now in the position shown in Fig. 2, when the dumping cord 71- can again 5 be attached to the bell crank lever H, as
show-n in Fig. 2. r
From the foregoing it will be obvious that by means of my invention the ordinary steam shovel can, within a few minutes, be
40 changed into a steam hoe, by simply reversing the dipper on the dipper stick, and attaching thereto, in the -manner described, a drag-line.
Having thus fully shown and described invention so that others may be enabled to utilize the same, I do not desire to be limu the dumping cord h thereby releasing ited to the exact mechanism shown and described, as many modifications can be made therein without departing from the scope of my invention; therefore what I claim as new and desire to secure by Letters Patent is:
1. In an apparatus of the class described, a dipper, a plurality of spaced ears having openings therethrough adjacent to the front and rear edges of the upper side of said dipper, a dipper stick, plates secured on the lower end of said dipper stick, lateral arms extending from opposite-edges of said plates and overlapping said ears on said dipper and having openings which coincide with the openings in said ears, and pins through said openings in said ears and arms.
2. In an'apparatus of the class described, a dipper-stick, a dipper, means to pivot the front edge of said dipper to said stick, a pulley pivoted on said dipper-stick, and a dragline secured to the rear end of said dipper and passing over said pulley whereby the open end of the dipper is tipped downwardly to the work.
3. In an apparatus of the class described, a dipper-stick, lateral arms secured on said dipper-stick, a pulley in said stick; a dipper, means to hinge the front end of said dipper to one of said arms, and a drag-line secured to the rear end of said dipper and passing over said pulley adapted to swing said dipper into contact with the other of said arms.
4. In an apparatus of the class described, a dipper-stick, means to impart longitudinal movement to said dipper-stick, a pulley in said stick, means to lift the free end of said dipper-stick, a dipper,.means to hinge the open end of said dipper to said dipper-stick, and a drag line secured to the rear end of said dipper and passing over said pulley adapted to draw said dipper toward the source of power. v
In testimony whereof I afiix my signature.
WARREN D. WILLIAMS.
