- To @ZZ whom t mag/concern.-

Be it known that 1 JEREMIAH CAMPBELL, a

citizen ofthe United States, residing at Chelsea, in the county'pof Sunolk and State of Massachusetts, haveinvented a new and useful Improvement inHoisting and Conveying Apparatus, of which the following is a full, clear, and exact description, reference beingv had ,to the accompanying drawings, forming apart of this specification, inexplaining its nature.

The invention comprises a movable hoisting and conveying apparatusL employing a steam-shovel, its operating devices, a transferring-trolley, and an operating-engine movabley horizontallyand having a short boom- .section upon which lthe v.trolley is movable and which is used in connection with a series of stationary booms with which thesaid .mevable boom-section is brought into line and used in any order or sequence desired;

In' the drawings,Fignre 1 is a view largely in side* elevation of my improved apparatus. l

Fig. 2 is aview insetion upon the dotted line 2 2 of Fig. 'land in planliof parts below said linegl Fig. 3 is a view principally in plan,

showing'a number of stationary booms and' the movable boom-section, steam-shoveh'trolley-operating engine, &c.

A represents a car or truck, the wheels a ofk which are mounted upon the tracks a', by

- -which the car, or .trucktmay be moved in any desired direction or to any required location. This car or trucksupports at one side a shovel and trolley-operaiting'en gine B. A t the other -side it supports a hopper C, having an opening c in its bottom. The car or truck also supports above the engine B asection D of a trolley-boom which is adapted-to be used in connection with any one of any desired number of lstationary booms B', the inner ends of which are arranged to be in operative rela'- tion to the movable boom-section vD,vwhenr brought in line therewith. The movable boom-section D isemployed. principally as a p rest or support for the trolley E when itis 4bein g moved from one boom to another. vThe trolley is showni'n full lines upon the station so'n The trolley is movable bac ward and forary boom B' in Fig. 1 and in dotted lines-upon the movable boom-section D.

ward` upon any one of *thestt-.ionary boms B b vfan voperating-ropewhich passes from fone end of the trolley', about a sheave b at the lend ofthe stationaryY boom, backward over the stationary `boom and the movable boomsection, about afsheave 19'., to aWinding-spool D of theengine, about which it `is-wonnd and from which it extends backward over asheave, companion to the Vsheave b', vto the trolley E. The trolley carries a set e of two sheaves, over whichl the shovel operating ropes extend to the shovel `F. The shovel is a steam'- shovel of the clam-shell-variety, which automatically takes its load and releases .it' and is operated by a hoisting and lowering rope f and an opening and closing rope j".v `These ropes pass "over the set of trolley-sheaves c to sheaves b attherear end of the movable boom-section D and from Vthenceae-their'respective'winding-druins.

.The position of the steam-shovel and its operating-ropeswhen in loperative position vupon a fixed boom is represented in full lines in Fig. 1.

upon the,movableboom-section B' to a position represented by dotted lines in Fig. 1. It is therefore desirable to supply each stationary boom-section with a trolley-actuatin g rope ywhich shall b e rove through the sheave b, at

the end thereof,and which shall have its ends` arranged near the rear end of the boom. Any desirable shovel and trolley and operatingengine may be employed. y The obect of the invention is to provide `means for employing the same .automatic hoisting and con-veyingshovel and its Aoperating devices -upon any; one'.` of a= series of booms whereby the coal'or material beneath said booms may be hoisted and conveyed or transferred.

It will be neces-v .'sary, however, to disconnect the trolley'from its operating-ropes and to move'the trolley` IOO While I have shown the shovel as hoisted and lowered and opened :md closed ,by two ropes, 'I would say that the number of ropes so employed for accomplishing this purposey forms no part of my present invention, and I should consider it practiced if the shovel were hoisted and lowered and opened and closed? by a single rope or by more than two ropes.

Having'thus fully described my invention, l I claim and desire to secure by Letters Patent of the UnitedStates- 1. In a hoisting and convey-ing apparatugg the combination of a movable car or truck, a shovel and trolley operating engine mounted thereon, a space' in which the steam-shovel may be held while it is beingI moved withthe car ort-ruck, and a movable boom #section adapted to hold the trolleywhile it is beingk l transferred with the shovelland engine, .and

two or more stationary bepm-sections with which said movable section is adapted to co,

j operate.

2. In combination, the car or truck A, .a shovel and trolley operating `engine carried 1. thereby, a hopper C, a movableboom-'section D adapted to lreceive and hold the trolley, the

sheaves mounted thereon and two' 'o1' more stationary booms.

.3'. The combination of the truck or car A, the shovel and trolley operating engine thereon, the steam-shovel carried thereby with its operating-ropes connected therewith,the trolley "eer-Pied -therebydiscomiected from its operating-rope and a boom-section or support for said trolley carrying'sheaves for the operating-rope and which `boom-section or support is adapted to be moved into line with a stationary boomesection, and said stationary boom-section.

4. 'The combination ina. hoisting and conveying apparatus, of a movable truck or car, a. trolley-support :mounted therein, :a trolley carried thereby, fa.' support at one side of and below the trolley-support, a `steam -shovel .adapted to be .carried upon vsaid support and the shovel operating rope extending vover a.

sheaivefcm said trolley to an operating-engine.
