STEAM-SHOVEL.

SPECIFICATION forming' part of Letters Patent No. 715,470, dated December 9, 1902.

Application filed October 21, 1901. Serial No. 79,410. (No model.)

To all whom, t may concern,.-

Beit known that I, FRANK FRANZ, a citizen 'of the United States, and a resident of Uvallace, in the county of Shoshone and State of Idaho, have invented a new and Improved Steam-Shovel, of which the following is a full, clear, and exact description.

This invention relates to a machineV for shoveling and conveying earth, rock, and like substances; and it comprises certain novel mechanism, which will be hereinafter fully described.

This specification is a specific description of one form of the invention, While the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side view of the device. Fig. 2 is a plan view thereof. Fig. 3 is a section on the line 3 3 of Fig. 4, and Fig. 4 is `an en larged plan view of the invention.

The machine has a hed a, mounted, preferably, on wheels a', so that it may be conveniently moved from point to point. On the bed a is erected a scaffold a2, from the base of which projects a branch a3, these parts CL2 and as being connected at their upper ends by bars a4. The branch a3 of the scaffold o2 has a boom b, pivoted thereinat the point b". The inner end of the boom b is forked to receive loosely a horizontal cross-head b2. This cross-head is fitted to move vertically in a scaiold a5, mounted on the bed o. The scaffold a? is pivoted on the bed by means of a pin n.5. (Shown in Fig. 3.) Now owing to the arrangement of the parts a2, b, h2, and a5, as

described, the boom b may move in a vertical plane around its pivot b', and it may also swing in a horizontal plane around the pin d6. As the hoorn swings horizontally it slides on the cross-head b2, and as it moves vertically it raises and lowers the cross-head in the scaffold a5.

b3 indicates ropes connected to the crosshead b2 and wound over a drum b5, so that by turning the drum in one direction or the other the cross-head, and hence the boom, may be raised or lowered.

b indicates a gearing for connecting the drum to the engine, and b" indicates a frictionclutch for starting and stopping the movement of the gearing. Thus by driving the drum h5 in the direction desired the necessary vertical adjustments of the boom may be effected. l

On the boom b, at the outer part thereof, is a guide-bar b4, which'may be of any suitable form and which runs longitudinally along the under side of the boom and is slidably connected to an eye c' on the shovel c. By these means the shovel is mounted to travel back and forth along the boom from its outer end to the scaold.

d indicates an engine of any sort desired, which is mounted on the rear part of the bed and provided with a friction-gearing d', by means of which two drums e and j' may be driven at will in either direction.

VI will not describe the details of the friction-gear d', since this forms no part of my invention. Any suitable mechanism may be employed for the purpose so long as this mechanism will impart the above-described movements to the drums e andf. These drums e andfare mounted on the bed a on transverse axes. The drum ecarries,as best shown in Fig. 1, `two ropes e and e1". These ropes are wound oppositely on the drum. The rope e runs over gide-rollers e3 to the outer end of the boom, where it passes around a guide roller or sheave e4 and runs inward to the shovel c, so that by winding up the rope e the shovel is drawn outward along the boom.

The rope e2 passes over guide-rollers e5 directly to the shovel c, so that by windin g on the -rope e2 the shovel may be dumped. The rope ,e2 is connected to the upper part of the shovel, -so as to effect lthis dumping. `served that when one of the ropes e or e2 is It will be obwound on the drum e the other rope will be unwound. The drum f carries two ropes f, which pass over guide-rollers f2 at each side of the scaffold o2 and are connected, to' the lower part of the shovel, so that by winding up the ropes f the shovel will be drawn toward the machine.

Mounted on the bed and running from the base of the scaffold a2 upward and rearward thereon is the frame g of a conveyer g'. This conveyer may be any ordinary form of endless conveyer and runs over pulleys q2 and g3 at the respective ends of the frame g, the pul- IOO ley g8 being driven from the motor CZ by a belt cl2 or other suitable connection. At the lower or receiving end of the conveyer is a boot g4, up which the shovel c runs to dump its load 5 onto the conveyer. The conveyer discharges its load at its rear or high end, and a car or other receptacle for the material may be run under the conveyer, as indicated at i.

Suitable brace ropes or rods 7c are provided, xo these ropes or rods passing from the upper end of the elevator-frame g to the scaffold a2 and connected centrally thereto, so as to permit turning of the scaffold as desired.

Z indicates a rope or chain connected to the l 5 base of the scaffold 0,2 and passed over pulleys Z on the bed a. This rope or chain also passes over a capstan Z2, so that it may be actuated to turn the scaffold, and consequently the boom, as may be desired.

In the operation of the apparatus the gearing d is so actuated as to drive the drums' e and f, so that the shovel may be drawn back and forth along the boom. As the shovel, with its load, nears the bed of the machine it rides up on the boot g4, and then the movement of the shovel should be stopped and the rope e2 drawn to dump the shovel. Then by drawing on the rope e the shovel may be returned for another load and its operation 3o thus continued. Meanwhile the conveyer g is operating continuously to carry up the material and dump it from the high end of the conveyer, as Will be understood.

Various changes in the form, proportions, and minor details of my invention may be resorted to without departing from the spirit and scope of my invention. Hence I consider myself entitled to all such variations as may lie within the scope of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of a frame, a conveyer thereon, a boot at the base of the conveyer, sa'id boot slanting upward from the ground, a shovel, means for moving the shovel toward and from the boot, and a boom mounted on the frame above the boot, on which boom the shovel has sliding movement.

2. The combination of a frame,a conveyer thereon, a boot at the base of the conveyer, said boot slanting upward from the ground, a shovel, means for moving the shovel toward and from the boot, a boom mounted on the frame above the boot, and a guide rod or bar on the boom, on which rod or bar the shovel is slidably mounted.

3. The combination of a frame, a scaffold mounted to turn thereon on a vertical axis, a 6o boom pivoted intermediate its ends on the scaffold to swing vertically, avertically-movable cross-head mounted on the frame and with which the boom has sliding connection, and a shovel mounted on the boom.

7. The combination of a frame, a boom mounted intermediate its ends to swing around either of two crossing axes, a crosshead mounted to move transversely of itself and lying approximately parallel to one of said axes of the boom, one end of the boom being engaged with the cross-head to slide longitudinally thereof, and excavating devices coacting with the boom.
