HOISTING A ND CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 694,378, dated March 4, 1902. l

Application filed April 22, 1901. Serial No. 56,870. (No model.)v

To @ZZ whom, t 1mi/y concer-n,.-

Be it knownthat I, HENRY H. GUFFIN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Hoisting and Conveying Apparatus, of which the following is a speciiication.

rlhis invention relates to improvements in hoisting and conveying apparatus in which a traveling carriage runs on a tram Iope or cable,the load to be conveyed being supported by suspension from said carriage and the carriage and loadbeing controlled and drawn back and forth on the tram-rope by means of cables or ropes operated from a hoisting-en gine.

The object of the invention is to provide means whereby a two-drum engine can be made to do the Vwork of a three-drum engine in performing the combined work with two cables, of excavating the material to be transported, hoisting same, and then conveying it to the place of discharge and discharging it. This Work heretofore has required three ropes or cables where I use only two, and has required a three-drum engine instead of a twodrum engine, which I am able 'to use, thereby cheapening the cost of a hoisting and conveying outfit, reducing the number of parts to keep in repair, and simplifying and making easier the operators work by lessening the number of parts to be handled by him in controlling the mechanism.

I accomplish the objects of the invention by the mechanism illustrated in the aecompanying drawings, in which-'- Figure lis a side elevation of a hoisting and conveying apparatus embodying my improvements, in which is shown the receptacle at the bottom of. the pit being loaded preparatory to being hoisted and conveyed; Fig. 2, a like view showing the traveling carriage advanced and the receptacle about to be inverted to dump the load; Fig.'3, a detail in perspective of the carriage andthe lock for holdingitin position over the pit; Fig. 4, a vertical section of carriage-locking device,

' showing the friction-rollers on which said Fig. 6 a rear elevation, of thepreferred form of receptacle; Fig. 7, a section on the dotted line 7 7 of Figs. 5 and 6; Fig. 8, a side elevation of a modified form of my outfit, in which the cord for hauling in the carriage-lock is -attached to the sheave-wheel of the engine and in which the hook for dumping the bucket is suspended from the tramway instead of from the carriage; and Fig. 9 is a plan view of a two-drum hoisting-engine of common form.

Like letters of reference indicate like parts throughout the several views of the drawings.

My invention is designed for use in excavating and conveying earth, sand, gravel,A

and the like. It is adapted for use in excavating trenches, canals, dac., and especially for taking sand and gravel ont of pits where the commercial value of the material excavated for building purposes and the'like is the sole purpose of moving it and the low price to be obtained requires an apparatus that can be installed cheaply and operated rapidly at small cost.

I have shown in the drawings an apparatus containing my improvements as they would appear in use for excavating gravel from a gravel-pit.

The device here shown consists of a support A, placed on one side of the pit B, and asecond support C, called the dump-mast, placed on the opposite side of the pit far enough away to allow room for the making, of a gravel-pile D with the excavated gravel.

E is the tram rope or cable, which extends across the pit or proposed pit from one support to the other, where it is carried over sheaves aand c, attached to the irrespective supports A and C, and the ends of the cable are attached to one of the blocks of the tackles d d', which are anchored to the ground, as shown in Figs. 1 and 2. These tackles are used to tighten up the cable E. By Yhaving a tackle at either end of the cable there are two chances to adjust and make the cable 9 F is a hoisting-engine of any suitable and well-known construction, having two winding-drums l and 2.

G isithe carriage, having the side frames h h', the construction of which is clearly illustrated in Fig. 3. This frame has three grooved wheels h2 4h2 h2, which rest on the cable and upon which the carriage travels along said cable. l The frame also has the two pairs of idlers I Q1 and fi' t" and the two sheaves j' and ji and the extensible rod J, terminating with the hook j. The frame also has the latch-bar I, pivotally secu red tothe front end of the carriage to engage a lock K on the cable over the pit where the carriage is to halt during the filling of the receptacle. This latch consists of two bars or levers parallel with the cable connected by transverse bars at their'ends and pivoted to the front of the carriage at about their centers. A set-screw t3 forms an adjustable stop to arrest the upward movement of the adjacent cross-bar of the latch and to prevent the transverse bar at the opposite end from dropping down into chaing contact with the cable E.

The receptacle L, which is used to excavate and transport the sand and gravel from the pit, is made preferably of iron or steel and is nearly elliptical in cross-section and is provided with an adjustable bail l, whichis secured to the Walls ot' the receptacle opposite its longer diameter. The front of the receptacle has the upper extension Z2,wit.h serrated edge to more readily penetrate the earth andcause the receptacle to iill as it is drawn forward in the pit by its bail l, and in order to regulate the 5 bite of the receptacle into the earth I make the bail adjustable, whereby its angular relation to the front Wall of the receptacle can" be changed to suit the conditions of the earth to be excavated. The lower end s of the bail are pivotally secured to the sides of the receptacle by the bolts Z3, and on circles concentric with said pivots are a series of holes Z4, through which bolts Z7 are passed. The angular position of the bail can be changed by changing bolts Z7 from one set ot' holes to another. the bolts ls permit of adjustment there also. The rear of the receptacle is iiattened and provided with external flanges L3, which approach each other at their lower ends to act as guides to direct the hooked end of rod J of the carriage down to the horizontal bar LVT at the bottom of the receptacle. The hook of rod J engages this bar L7, and when so hooked and the receptacle released by the slacking of the rope or line supporting it the receptacle is dumped by swinging down around this hinge-like support. The bail 'Z has a central lug, through which are two eyes, to the upper one of which the frame of a sheavej3 is attached, and to the lower eye they rope m, called the load-line or inhaul-line, is fastened. This linem passes thence to the drum l ot' the engine and is wound upon it. When the receptacle v'tering the hook.

Holes on either side ofv is at the bottom of the pit, it is drawn toward the engine and lilled by the winding of the line m upon the drum 1.

The rope n, called the hoist-line or outhaul-liue, which is wound upon the drum 2, passes thence between the idlers fi t' of the carriage and also between the idlers i t" of the carriage, thence around a sheave in a block o near the top of the mast C, thence around the sheave j2 on the traveling carriage, thence down and around the sheavej'3 otthe receptacle L, thence up and around the sheavej on the carriage, and then ce down to the block or frame supporting the sheave js of the receptacle, where it is made fast.

The drums upon which the ropes m and n are wound are operated by an ordinary hoisting-engine, as before stated, or by any other approved motor, and are provided with the ordinary brakes and levers (not shown) for operating them separately or together.

The lock K consists of a bar laid on top of thecable or tram-rope E. It has the weight E depending below the cable to lower the center of gravity and maintain the bar in position. The end ot' the bar toward the carriage G has the oblique surface shown in the drawings terminating at its upper end with hook la, which engages and holds the latch I of the carriage, preventing the carriage from moving away from the lock until its latch-bar is freed from the hook by the bail la?. The bail k2 is pivoted nearest its upper end to the lockbar K, whereby itis made to stand normally in vertical position. The upper end of the bail, however, is longenough to reach the end ot' the hook k and serve as a guard when the latchbar I has passed to the far side of itfrom en- In practice when the carriage is held by the lock and it is desired to release it the carriage is moved toward the lock until its latch-bar has passed the bail k2. Then the carriage is run back and the latchbar rides up the bail, over the hook, and the carriage is free.

The operation of my invention is as follows: Taking the apparatus in position shown in Fig. l, the receptacle at the bottom of the pit is lled by being drawn toward the engine by the winding in of rope m. When f ull, the receptacle is hoisted out of the pit by the winding of rope n upon its drum 2. The carriage is locked, so it cannot be drawn toward mast C by the winding up of the rope. The receptacle is raised above the hook on bar J, then is let down upon the hook,and then the weight is largely transferred to the bar J. During this hoisting operation the rope m has been slack, but it is now reeled up on its. drum and the carriage drawn toward the engine far enough to pass the bail of the lock with its latch-bar. Then, as much of the load ofthe receptacle is taken ott of the outhaul-line n by the support of bar J, the winding of rope n on its drum instead of raising the receptacle draws the carriage and receptacle back to- IOC IIO

Ward mastvC, the line m being loose. When the desired place for dumpingis reached, the rope n is slaeked, which allows the recepta# cle to swing on hook j and invert itself. The

lcarriage is then Yreturnedto aV lockedrposition A which may interfere with the com plete lowering of the bucket-like'receptacle to the bottom of the pit because of its tendency to iioat, I provide the adjustment of the bail, previously'described, to'assi'st in 'sinkingthe receptacle by attaching the weight ofthe sheave and cable where it will have more effective action. Thisl is`an additional freature'of advantage in the adjustable bail beside that of regulating the bite of 'thefreceptacle previously mentioned. As thevexcavation proceeds the desired place for stopping the carriage and lowering the receptacle changes, and to change the position of the lock on the cable I attach a small cord or wire p to thelock K, run it over thepulley p' on the mast A, and wind it upon the reel P. By Winding this line on the" reel the lock will beV 'drawn toward vmast A. It `c'an'be moved in the outward direction by leaving it hooked to the carriage. The'n by slacking up on the line 1o and running the carriage out in the manner heretofore described the lock will be moved toward nastC. i

. Whereagravel-pile is just being started, and is therefore low, orwhere the gravel-pit is quite deep, I have found that 'Iican save muchtime of hoisting the receptacle by not raising it higher than is absolutely necessary to just pass over obstructions. After the receptacle has been raised by rope vn to the height just mentioned and so the pull on rope m would be down instead' of up, as in the pit, a pull on the rope m will draw the carriage and' its load' forward enough to 'unlock it. Then the carriage and its receptacle will move toward the' mast C bythe winding" upon its drum ofthe rope it, because the moving of the carriagerequires less power than the hoisting ofV theV receptacle. TheA receptacle will 4thus be transported to the dumping-place without being elevated to the hook on the carriage,'and a' stationary hook suspended fromrthe tram-rope will be required todu mp the load. Such a stationaryhookisshow at,

Rl in Fig. s.

`Vihere the receptacle is to be filled by hand by men with shovels, the load-line can be dis-l pensed with; but where the load-line' is dis# pensed withV the lock for the carriage must have its retaining line or cord loosened'each time, so that the lo'ck will be carried out with the carriage in order that the carriage may be returned by reeling in the line, which is fastened to the lock. i In this apparatus a lock mounted on rollers r r, as shown in Fig. 4, Will be'desirable to prevent abrading the cable. Where the line m is dispensed with',- its drum Z is not needed and may alsovbe dispensed with. l

` Most hoisting-engines have a sheave-wheel (see S, Fig'. 9) mounted on the' Vend of the drum-shaft, and, if sodesired, instead of reeling the line p of the lock K by hand itcan be wound upon the sheave-WheelI by the engine.
