To of, whom it may concern.-

.lle itknown that wefWILLIAM HENRY HOB.- cns and CLARENCE 'L. TAYLOR, of Alliance, in the county of Stark and State of Chic,

have invented certain new and useful rmmovements in Cranes; and we do hereby declare the following to he a full, clear, and ox not description oi the invention, such as will enable others'skilled in the art to which it np 1o pertains to make and use the same.

Our invention relates to an improvement in cranes adapted particularly for forge shops the object being to provide an over head traveling with means for manipulfi-lilllg the forging-such aselevatihg or lowcring it, turning it horizontally, and rotating it; and our improvement consists in the parts and combinations of partsQns will benzene fullydescribed, and pointed out in the 01- .ims. In the accompanying drawings, Figure l is :1. view in elevation of a crane embodying our invention. Fig; 2 is a plan view of the trollley; Fig. 3, a side view of same. Fig. i is a view of the mechanism for rotating the forg- :5 ing, and Fig. 5 is a diagrammatic view of the elevating and lowering mechanism.

A represents an overhead traveling bridge propelled by the motor 13 This motor actuntes the she-ft C, running and the shaft is provided pinions a, engaging the the flanged trackat its ends with the larger pinions b, fast to wheels 6, which latter: rest and move on the elevated rails.

' Mounted and moving on the upper faces of the bridge-girders is the trolley D. This trolley is carried by the flanged Wheels (Wand is propelled longitudinally on rails on the bridge by a motor and gearing in the ordinary 4e manner and is provided on its upper face with a circulartraclswoy e, on which the upper section D of the trolley rests and moves. his upper section D of the trolley is provided Witllft depending circular flange or mil '6 which hitter rests over the circular track;- way 6' and on the conical rollers e, the trunnions e of the entire series of which are jour-.

nalecl in the circular rings a, one of which connects the outer ends of the rollers. while go another (not shown) connects their inner lengthwise one of ends. With this construction it will be seen that the ,topsection D of the trolley can be rotated or turned on the lower section. Hence any work suspended from the. ripper section can he turned horizontally, so as to bring the work under the hammer or other tool irrespeotive of the location of the letter with re spect to the furnace.

Secured on? the upper. section D of the trolley is the motor E, the armature-shaft of which is provided with a hovel-gear j, which meshes with a, hevel 'gez r f on the upper end of vertical shaftf This shaft is mounted on the upper section D of thetrolley and is provided at its lower end with a pinion f which engages the circular reel: f' on the -lower section I) of the trolley. By meansoi this motor and gearing the upper section I) of the trolley can he turned on the lower sec tion, and thus thru the work horizontally, as previously described.

Secured on the upper face of the movable section D of thetroliey ere the two'motors G and G, the former of which we term the revolving motor and the latter the hoisting motor; These motor-s ave geared up to a. system of gearing for actuating pocket-ed sheaves or drums supporting the cables ear rying the ingot or work to be forged, so that said ingot can be raised or lowered and re So volved, the several movements of raising or lowering and revolving being sinuiltaneous or independent, as desired. The hoistingmotor G carries on its armature-shaft the small pinion g, which meshes with a larger toothed Wheel g on'shn'ft g? This shaft is journe-led in hearings in the motor-casing and also in bearing g? and carries at itsotherend the small pinion g", meshing ,with-tiie' large toothed wheel II. mounted on shaft H and is provided with a hub h and an integrel pinion h.

Mounted on the hub -'h is the internal and external spiir -wheel H, the eiternal-teeth'ofwhich mesh with the pinion h on'the revolving motor-shaft, while the internal teeth in sh with the series of pinions hf, loosely mounted on the bearings h, carried by the dist: it, keyed to shaft Ii, the pin ions it also meshing with the Wheel h, fast to toothed. mo

' This Wheel 11' is loosely go I toothed wheel H ivheel v This lsooarries the pocketed sheaves h? io'li are Keyed to the shaftso-es totem therewith.

Tootliedwlve'el E "which, as before stat-ed, is loose on assess, meshes with the toothed wheel Ht, which is loose on the shaft 11 and is identical in en's-store withiwheel H and hm soul) li and a smell Soothe- 1 wheel" 7L Mounted on the hub 72, 315 the internal and external spur-wheel H the outer teethv of which mesh with the pinion k on the revolving motor-shaft, while the internal teeth thereof engage the piniozis on the beerings h ,oesried by the disk7 rigidly keyed to shaft H The pinions i21 also mesh with the pinion h, which is. iotegyal with the J Secured to shaft H are the poeketed-sheeves h.

' Two endless chains are passed over the sheaves hf and h each chain gassing no over one sheave F2 and also over the oppose sitelydisposed sheave and felling iii-e. loop belovvthe sheaves. The two chains-l thus supported eeeb carries in itslowei' looped end a pocketed sheave 3 the tWoshea-ves .l-- being mounted on opposite sides of the crosshead K. T

Secured to the wheels I, so as to'rotete. iherewitmet-e'the piniotas L su speodei from thecross-heed K is the yoke L, the. upper head of whioh'is suppers-ed by spring L resting on the 'o ross-heed, while the lower bifurcated end carries the sprocket-wheel L and the-pinions L the latter being connected to the sprocket-wheel so as to turn therewith. The pinions-ifere geared up to the ,pi'nions L by the pinions which as clearly shown in Fig. '1, ate carried (m -the jointed svms lid, which latter ave loosely mounted at their ends on the bearings for the pioions L and L By this construction the wheels follovvnptlze wheels I under varying tensions of spring L end are always in engagemeat therewioh, so as to impart rotary mo 'tion thereto from the wheels L.

An endless chain N is eerried by the sprocket-wheel L and forms a loop is which theingot or forging or tool for manipulating the forging rests.

For the purpose oi illustrating the "tion of the parts which elevate lower, and revolve the forging we have used series 01' sirrows marked 1 for indicating the movements of the several pai'ts'while raising or lowering the forging and arrows marked '2 for indicsting the movements while revolving tlpo forging, the several arrows being reyresonted above the shafts,

For lowering the ioad. the hoist-motor G 1 would be operated tot-um Wheel H in the direction indicated by the arrow thereon and it in turn, meshing wits toothed Wheel will 41 rive it,as indicated. 7 The wheel H would transmit motion through its pinion h to the piuions 79, and from the letter through flee disk k to sheft 1; and its pocketed sheaves h? rotating the latter miles digestion (i assesev I rows '1.

to the pocketed sheaves h. Bylreversing, the direotion oi the-rotationof the niotolfllv a reverse motion will-0e*iixipartedtofthe' sheaves It? and it, thus 'lifting -the-loadf caress by the chain-blocks. -.The"l'inksjof the hoisting-motor and starting the revolving mo-;

tel-motion is imparted through pinion h to the wheels H and H which; as before explained, aieloose on the hubs of the wheels- H and H The wheels H and H are revolved in the same direction as indicated by the ar- 0 rows 2; and Lheyin turn carry the pinions h hf around on their respective pinions h and h; thus rotating the disks h and 72 and 'imgierting throsgli said disks motion to the shafts H and H and to the pocketed sheaves .h' and 72- the latter revolving in the same direo tion. With the sheavesrevolving in the some dizection it will be seen that the chains l iestead of elevating or lowering the sheaves .l', carrying the chain-block, simply revolve these wheelsend the latter, through the intervention of the pinions L, LflandLfirevolve spi'o'oket-wh'eelL end the endless chain N, carried tliereby, and as the-forging or tool is v carried. oy'the chain N it will be revolved in the direction of movement of the chain.

By imparting motion to the hoisting and revolviog motors at theseme time and at diffeeent rates of speed it will be seen that the forging be elevated-oi lowered and reno volved {on Ponsly and by revolving the upper section D of the trolley the forging can be turn d. one of these movements can be ire-parted singly or they can be imparted simultaneously, excepting, of course, hoisting x 15 and lowering. Hence it will be seenthot the *"orgng can be carried to any part of the mill to bring any garb of same position to be operated upon.
