Specification of Letters Patent. Patented O t 19 1920 Application filed August 9, 1919. Serial No. 316,383.

T 0 all whom it may concern.

Be it known that I, ERRETT E. PHILLIPS, a citizen of the United States, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Excavating Apparatus; 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 and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in hoisting and excavating apparatus for use upon the surface of the ground or underneath same for various purposes, where soil and various materials are desired to be excavated, hoisted and dumped.

My invention consists of a simple and efficient device of this character having various details of constructions, combination and arrangement of partswhich will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings which, withthe letters of reference marked thereon, form a part of this application, and in which:

Fig. 8 is a detail view of means for bold ing the boom, illustrated in Fig. 1, in (hit ferent adjusted positions.

Reference'now being had to the details of the drawings bynumeralsz' I Referring to Fig. 1 of the drawings, .1 designates the base upon which a suitable derrlck 2 is mounted, havingcrossbeams '3 at the upper endthereof, in which are ournaled pulleys 4 and 5. A pulley6 is journaled in suitable bearings upon a cross piece 7 of the derrick, and 8 designates an other pulley which is journaled insuitable bearings near the lower part of thederrick.

A swinging boom, having parallel pieces, has a bracket shaped member 9 connecting their inner ends, and which member is pivotally connected at 10 to a yoke 11, havin apertures toreceive the vertically dispose rod 12 which is fixed to the derrick spaced apart a slight distance therefrom, asshown passes over the pulleys 4,4 and 5 under neath the pulleys 8 and thence extends to and passes about a reel 26 journaled upon the capstan shaft 27', which has a squared end 27 adapted to receive the capstan lever 31provided with a similarly outlined opening therein to receive the angular outlined part of the capstan shaft 27'. Integrallugs 28 project from the upper face ofthe reel, and are provided with registering apertures to receive the rod 30 asshown clearly in Fig. 3 of the drawings, which rod also passes through a registering aperture in the capstan. A rope 1 1 is fastened at 14 to the yoke 11 and passes over the pulley 6, and carries at its, other end a handle piece 14,

which afiords means for raising and lower- A handle 1 is fastened to the bracket member and serves as a means for swinging the latter to engage the spaces intermediate the lugs or to be drawn free from the same to permit the boom to be raised and lowered while in operation.

In Fig. 8 of the drawings is shown additional means for holding the boom in different adjusted positions, and consisting of yokes having integral collars 86 at the ends thereof, adapted to receive the vertical rod 12 rising from the sill of the derrick, and which yoke has a handle 37 fixed thereto, providing a convenient means for swinging the yoke, so that the projecting members 38 thereof may be made to engage the recesses 39 in the post 40 of the derrick.

A scoop shovel, Fig. 4, 1'7, with a suitable handle 17, has straps 18 fastened thereto, each of which is supported by rings 19, adapted to receive the rod 16 upon which they are movable. Said scoop shovel has a rear end 20 which is hin ed at 21, and is provided with a latch 22, and 23 is a rope fastened to said latch and forms means for releasing the same when it is desired to dump below it.

In Fig. 5, I have shown my invention illustrating a vertical hoisting cage 40, which has guide wheels 41 hearing against vertically disposed parallel tracks 42, said Fig. 5 illustrating a car 48 mounted upon wheels, this car is within the cage 40. A hoisting cable 44 is secured to ring bolt 45 upon the cage, passes over a pulley 46 rotating on top of the shaft 47, which latter also carries a pulley 4S. Said cable 44 passes underneath a pulley 49, and thence extends to and passes about a winding reel 50, which is of similar construction to the reel before described, and illustrated in detail. in Fig. 3 of the drawings, said reel having, however, a slightly modified form of means for causing the reel and capstan to rotate together, which consists of a sliding angle rod 51 held in suitable eyes 52, and adapted to engage apertures 53 upon the reel, said eyes 52 pro jecting from the lever 54.

Upon reference to Fig. 6 of the drawings, it will be noted that the rope 44 passes over a roller 55 which has a vertical movement, detail of which is shown in Fig. 7 of the drawings. Said roller 55 is mounted upon a bar 56, and 57 is a lever fulcrumed upon a pin 58 upon the standard 59 and which is connected to the bar,andby pressure on the lever, the bar carrying the roller may be raised to the position shown in dotted lines in Fig. 7 of the drawings. Asa means for holding the bar carrying the roller in different adjusted positions, abracket rod 60 is shown as having angled ends adapted to engage apertures in the standards 61. The capstan shaft, it will be noted upon reference to Fig. 5 of the drawings, is supported by bars, these laid in concrete for foundation. For purpose of guarding the entrance to the elevator shaft at the surface of the ground, a'suitable screen 42 is placed upon the shaft.

A suitable counter balance weight 62, shown in Fig. 5, has a rope 63 fastened thereto which passes over pulleys 64, and thence about the pulleys 48, in order to hold the cage in elevated'positions. Ring bolts, one desi nated by numeral 65 and fastened to a ross beam 66 of the shaft in which the cage is mounted, and the other,.67, on the cage, and 6S designates a double ended snap hook designed to engage the two ring bolts when the cage is elevated.

in the modified form of means for holding the cage elevated, consisting of a chain 70 passing through rings, as shown in Fig. 5 of the drawings, and a padlock '71 nay be passed through the rings at the end of the chain to hold same iocked. An additional means for supporting the cage consists of a horizontally movable rack bar 72 havin teeth upon the under surface thereof, and designed to be engaged by theteeth of the gear wheels 73, one of said wheels being rotated'by means of a crank handle secured thereto, so that when the cage is elevated, the rack bar may be moved underneath the same by rotating one of the gear wheels.

In operation, through the medium of the hoistin cable 13, the boom 9 may be held to operate at different elevations. By rotating the capstan 11 the reel will cause the cable 13 to wind thereon and the scoop shovel may be drawn through the soil or other material, the scoop shovel being directed through the medium of the handle 17', and when the scoop shovelis loaded and further pulling applied to the hoisting cable 13, the boom 9 may be elevatedjto any desired position and may be swung in different directions laterally, and when it is desired to dump the load, it may be done by the operator pulling upon the rope releasing the latch upon the scoop shovel, permitting the materiai to fall out at the rear end thereof.

When it is desiredto pullback thescoop shovel to its original starting position, the rod 30 may be withdrawn from engagement with registering apertures in the lugs upon the reel and capstan, and the scoop shovel may be pulled back through the medium of the rope 23 secured thereto. The boom, it will be noted, may beheld in different positions through the various means illustrated in Fig. 2 of the drawings, or throughthe medium of the mechanism shown in Fig. 8. The cable, as it winds upon the reel, may be raised through the medium of the lever 57 in order to permit the cable to wind evenly upon the reel. It will be noted that the means for causing the reel and the capstan to wind together is of similar construction, shown in Figs. 1 and 5 of the drawings, the cage in Fig. 5 being permitted to be lowered by releasing the angled rod connecting the reel to the capstan.

By the provision of a hoisting apparatus made in accordance with my invention, it will be noted that a simple and efiicient mechanism is provided for use either upon the surface of the ground or underneath as may be desired, and while I have shown a particular detailed construction of applying the principle involved in my invention, it will be understood that the detailed construction may be varied in different ways without in any way departing from the spirit of the invention.

What I claim to be new is:

1. An apparatus for hoisting booms, comprising a derrick, a vertical guide rod car ried by and spaced slightly from the derrick, a yoke provided with apertures through which said guide rod passes, a swinging boom pivoted to said yoke, a bracket member having parallel angled portions apertured to receive said guide rod, the ends of said yoke and said angled portions being superposed, laterally extending arms carried by said bracket member, and a series of spaced lugs carried by said derrick between pairs of which said arms are adapted to be moved to hold said boom in vertically adjusted position on said guide rod.

2.
