Operated Cranes of the Traversing Type, Commonly Known as Locomotive Cranes,-

of which the following is a specification.

The invention relates to locomotive cranes of the power operated traversing hoist type and has for its object the provision of certain improvements and refinements in the mechanisms for operating the boom and the tools carried thereby.

It is a further object of the invention to provide improved meansby which a crane of the type to which the invention herein shown is applied may be transported under its own power from place to place.

It is a further object of the invention to provide improved means interposed between the source of power-"on the swing body and the car body for operating the swing body The objects" above recited together with certain other improvements in the construc; tlOIl. of my improved crane are set forth in 'ticular reference to the drawings formingthe subjoined'specification which has para part thereof and the novel features of the invention are finally 'set forth in the apended claims.

Fig. 5 is a plan viewiof the boom and mechanism associated therewith for control- .face gear 20, which is engaged by the parts broken away,jthe tool operating cables being shown in section.

My invention is shown applied to a locomotive crane having the usual car body which in this case, as will be seen by reference to Figs. 1 and 2, is formed of sturdy channel iron and isof a general rectangular form, the side members of the same being indicated by reference characters 10 and 11, and the front member by reference. character 12, and the rear member by reference character 13. The car is supported by four carrying wheels, the front wheels being des-- lgnated' by reference characters 14, 15, and

the rear wheels, only one of which is shown, designated by reference character 16. The front wheels 14" and 15 are on a pivotally mounted axle 17 to enable the car body in transportation to be guided, but'no specific means for steering this .axle is. shown herein, as the same forms no part of the present invention, the axle 17 being merely shown connected to a king pin 18 pivotally mounted at the front end of the -=car body frame. The rear wheels, one of which .is shown at 16, are keyed to a-solid rear axle 19 (see Fig. 1), and the latter is rotatably mounted in suitable bearings, not shown, on the car body frame, so that both the rear wheels will be rotated whenever rotation is imparted to the axle. 19, the latter carrying the evel gear 21 on the longitudinally extending I drive shaft 22, the latter being supported in suitable hearings on the car body main frame and being provided with a bevel gear at its forward extremity, as indicated at 23, engaged by a co-operating bevel gear 24 on vertical shaft 25, which latter has keyed thereto at its upper extremity the gear 26,

which is engaged by suitable driving means to be described, whereby power will be 1ming rotation'to the driving axle 19 and enabling the car body to be moved by the. ro

body has rigidly attached to the upper side parted from the source of power for'lmpartthereof the large swin gear which is ex- .ternally toothed, as in icated by reference character 27, the latter being engaged by the spur gear'28, which is rotatably mounted in the frame of the swing body by being attached to vertical shaft 29, the latter being journalled in suitable bearings on the the frame of the car body, being made of rectangular form comprising the two lateral channel members 32, 33 which are connected at the front and rear by suitable cross connecting members, they forward member consisting of an irregular shaped casting iridicated generally by reference character 34,

and'the member at the rear being of channel form like the lateral or side members and indicated in Fig. 3 by reference character 35. There are suitable cross connecting members in addition to the end members 34,. between the longitudinal side members 32 and 33 of the swing body frame,vone of ably which is an irregular casting similar to the cross member 34 spaced on theopposite side of the, center of the swing gear 27 and indicated generally by the reference character 36. These castings 34 and 36 not only serve to support the swing body frame but are also provided with bearings and suitable openings or housingsto support anti-fric-. tion rollers, of which there are four shown, and designatsd by reference characters 37 to 40 inclusive (Fig. The upper side of the swing gear 27 is formed with a suitable bevelled track surface inclining downwardly and outwardly from the center of the swing gear, and the supporting wheels or rollers 37 to 40 inclusive are conically formed to correspond, thereby tending to cause the weight and strains thrown upon these parts by the swing body to tend to centralize the swing body on its pivot, which consists of the aforesaid vertical shaft 25, journalled at the center of the swing gear and in suitable bearings on the swing body frame.

At the front end of'the swing body frame is the, boom which is designated generally by the reference character 50 and is pivotally connected, as indicated in Fig. 1, by

pivot pins 51 in suitable bearings in the for-wardedge of the front connection 34 of the swing body frame. The boom 50 may be of the usual orany ordinary construction and is shown in the embodiment thereof in. Figs, 1 and 5 as formed of channel members,

- of which there are usually two in number,

spaced apart and arranged-to converge toward their outer extremities and being suit-' braced by cross connections," shown herein as indicated at 52. In Fig. 5 isshown a plan view of'the boom of a conventional The swing body form in which the sheaves and cables are in osition for operating the b'oomhoist.

he motive power for operating the boom hoist cables and the swing body may be of any desired form, as the steam engine, the hydro-carbon motor or an electric motor. In the present embodiment the motive power is illustrated in the form of steam engines of the twin cylindertype, the cylinders being located in line wlth the opposite ends of a crank shaft (Figs. 1 to 3 inclusive)- which carries suitable cranks or wheels 71, 72 carrying crank pins 73, 74 and connecting rods 75, 76 connecting with cross heads, as indicatedby reference character 77, Fig.

1, carried by guides 79, 80, which are also associated with piston rods and the usual pistons in the steam cylinders 81, 82. The reference character 85, Figs. 1 and 3, designates generally a steamboiler and in Fig. 1 is shown a conventionalform of conduit or pipe 86 leading to pipes, one of which is designated by reference tive power is not pertinent to the invention character 87 in-. tended to convey steam to the cylinders 81, -82. Since however, the specific form of monoattempt has been made to show these details except in a general way and for-the same reason, no means for controlling the steam from the boiler to the engine is illustrated. Power will be applied'to the shaft 70 by motive power as described, which shaft is journalled to rotate in either direction as desired. Attached to rotate with shaft 70 is a spur gear 71 in engagement with the large reduction journalled on transverse the holding or take-up shaft 73% carrying and power drums,

the former being designated by reference character 74 and the latter by 7 5. The power drum is preferably the smaller in diameter. of the twoin .order tomu-ltiply the leverage or lifting power of the cable carnied thereby, which is intended to do by far the heaviest work in connectionwith operating the tools carried bythe boom hoist.-

The gear 72 will preferably be mounted to rotate with shaft 73 while the drums 74 and 75 willbe journalled loosely on said shaft but adapted to be rotated with the gear 72 by means 'of suitable frictiondevices which will now be described.

gear 72 which. is

Pivotally connected on the inside of the toothed periphery of the large gear 72 -at 77 'is an arm 78 connected with an expansible band 79 engaging the periphery of one enlarged flanged endof the power drum 75 in such a manner manner in one direction the friction band 79 will be tightened around'the flanged por-" tion 75 of .the power drum while-mcve'ment of the lever 78 in the opposite direetlon Wlll obviously result in loosening the "friction" band 79. The preferred construction is that that as the lever 78 is rocked on its pivot 77 in a well known illustrated by which movement toward the' gear, 72 of the conical sliding member 80 will by engaging the roller 81 on the extremity of the arm 78 rock the arm so as to tighten the friction band 79 thereby causing the power drum 7 5 to be rotated in unison with the gear 72 which will be'continuously.

driven from the power shaft 70." The bold ing or take-up drum 74; has the effective cable reel thereon preferably of a slightly larger diameter than the corresponding part of the power drum 75" and the drum 74 is mounted loosely to rotate on the shaft 73,

under the control of a frictional device consisting ofa suitable frictional surface de s-- ignated by reference character 85 attached to the enlarged flanged portion 75 on the power drum 75. The flanged portion 75 of the power drum will be preferably engaged by a suitable frictional brake band indicated by reference character 87 shown in Fig. 4. This brake band may be of the conventional type and no specific means is shown for operating same as this forms no part of the invention. The function of the brake band 87 will be to control the power drum 75 against over-running in a well known manner. The holding or take-up drum 74' is provided at one end with a flange 74 which carries a counter-part frictional surface 86 for engaging with the tracting these bands'and thefsame-forms no- The'frictional brakebands. 87,88 may beof the same type and operated in the manner similar to the band 79 heretofore described. The operating means for the bands 87 and 8.8 is notshown as same'may be of any com-.

mon and well known construction for conpart of the-present invention. 89 and 90 respectievly desig'natethe bearings carrying the shaft 73 on the main frame. The main power shaft or engine crank shaft -'is carried by suitable bearings'91 and 92 (Fig. 3),

and is an integral shaft havin splined thereon so as to be slidable in relation to the shaft, but toturn constantly'therewith, two clutchdisks 93, 94-- (Fig. 4). with each of the slidable clutch disks 93, 94 are the spiders 95, 96. These may be of a disk like form 'or contain arms'for supporting a plurality of coiled springs 97,"the latterbeing adapted to normally press against Associated the clutch disks 93 and 9-1 to hold them out of engagement with the co-operatin frictional dlsks 98., 99. The last said dis have co-operating' frictional surfaces, as for example, the grooves shown in Fig. 4 which will take the projections on the disks 93 and 94 in a well known manner in this type of frictional clutches.

The disks 98 and 99 of the clutches will be journalled to rotate loosely on suitable supporting collars as indicated at 100 and 101 on the shaft 70 and any suitable means as the locking collars. 102, 103 may be used to retain the bearing collars 100, 101 in position. This construction allows the friction disks 98 and 99 to rotate freely on the shaft 70 when the co-op'erating parts of the clutches are released and they also carry bevelled gears which are designated by reference characters 104, 105 which are both in mesh with the large bevelled gear 106, which is keyed to the upper end nalled in suitable bearings on the swing body frame. 108 is a spur gear splined on the vertical shaft 107 andadapted to be operated to a" position where the teeth'thereon will enga e the teeth on the large gear 26.

When ad usted to this position, by some sultable shifting mechanism not shown,f as same forms no part of the present invention,

it will be seen that the gear 31 and shaft 29,

which operate the spur gear 28 for imparting a swinging movement to the swing body,

of vertical shaft 107, the latter beingjourwill be at rest and power from the driving shaft 70 throughreither of the bevelled gears 104 or 105 will be transmitted to and result in rotation of the vertical shaft 25 and the lon tudinal drive shaft 22 communicating wit the rear live axle, so that. motion either n the forward or reverse direction will be imparted to the rear driving wheels 16. and

will propel'the car body either in the for- .ward or reverse direction, as desired. It

will also be seen that a simple shifting movement of the gear-108. from-the neutral positionshown in Fig. 1 into' engagement with the teeth on thegear 31 will result in imparting rotation fromthe power shaft 70 to the swing body operating shaft 29 and pinion or gear 28 carried thereby, which will result in a swinging movement being imparted to the swing body on the pivotal or center, shaft 25'. In order to properlysupport the bearings of the mechanism just described'there' is an upper structure erected on the swingbody frame, consisting of the parts 32 to 36 inclusive. and, this may con veniently consist of suitable uprights ascthe vertical angle bars '110, 111 supported by" suitable angular braces at each sidea's' designated by reference characters 112 and 113, the latter be' swing body frame adjacent the longitudinal connected to the base of the side rails 32,33 thereof'and joined tofthe f vertical uprightsllO, 111 by some suitable of the boom hoist. The cable co-operating with these drums is designated generally by the reference character 121, Fig. 5, as is also the manner of mounting the same, from which it will be seen that the strands of the cable after being passed over the sheaves 119, 120 will extend downwardly and toward the drums 117,118 and will pass over the sheaves 122, 123 with a strand thereof uniting the parts of the cable over these respective sheaves, with the result that as the boom hoist shaft 115 is rotated to synchronously wind up the ends of the cable on each of the drums 117, 118 respectively. this shortening of the cable will in a well known manner by shortening the loops in the cable over the sheaves 119,120'elevate the outer end of the boom hoist on its pivotal connections 51 with the swing body frame. Motion to the shaft 115 carrying the boom hoist cable drums will be imparted by'means of worm 125 engaging worm gear 116 carried on the upper end of the vertical shaft 126 which is journalled in a suitablebracket 127 forming a part of the bearing for the boom supported by the transverse connecting bars.

128, 129 which extend between and are anchored to the vertical members 110. 111 of the upper structure of the swing body frame. This structure including the vertical mem bers 110, 111 and the angular braces 112 will preferably be strengthened by the cross ties at each side shown in Fig. 1 and designated by reference characters 130, 131, there being one. pair of each of these on opposite sides of the swing body frame.

To the lower cross ties 131 the bearings 89 and 90for supporting the shaft 7 3 carrying the holding or take-up and power drums ,74 and'75 will be attached, Adjacent the lower end of the vertical shaft 126' there is splined a gear 135. This gear has a hub 135 attached thereto or formed integrally therewith which is shown in Fig.1 as provided with a slot adapted to take 'ashifting fork, v

r the latter not being shown, as any common form of gear, shifting mechanismmay be employed, and by whichthe gear 135Vmay be caused to engage with the teeth of a gear 136 secured to the vertical shaft 107. From the foregoing construction it will be seen thatwhenever the operator shifts the gear 135 into engagement with the gear 136, rotation of the power shaft 7 0 will result in the actuation of the vertical shaft'126 and oper-,.

lowered as desired. From this construction it will also be seen that if it is desired to cause the boom hoist to remain in asuspended position the disconnection of the gear 135 from the gear 136 on the vertical power shaft will secure the desired result. the boom hoist drums 117 and 118 being held against 1 giving off the cable by reason of the locking effect of the worm 125 engaging. the gear 116 on the drum shaft 115. The reference character 140 on the boom hoist designates a suitable shaft furnishing bearings for the-- sheaves 119, 120 of the boom hoist cable 121. At a point preferably a little nearer the extremity of the boom hoist is secured -'a transverse shaft 141 furnishing a; bearingfor the sheaves 142. 143 over one of whichwill be passed a cable from the power drum 7 5 and the other of these sheaves will take the holding or take-up cable from the drum J, by re erence character 151". This arrange holst drum shaft 115 and Wlll preferably be 'cable drum,

ment of cables for operating the boom hoist of the boom hoist and mechanism carried thereby forms no-part'of the present invention. v

In the aforesaid embodiment of the invention as shown in the drawings and in the description no attempt has been made to illustrate detail means for shifting or operating the clutches on the power shaft 70 or the brake bands controlling the cable drums, as these features together with the specific means for operating sliding gears such as the gear 135 on vertical shaft 126 operating the boom hoist drumsfand the sliding gear, 108 'on vertical shaft 107. may be controlled by gear shifter devices of a variety of constructions well known to those skilled in this art, keeping in mind that these controlling means are usuallymain power shaft 70 and the clutches thereon a pair of eccentrically splined collars-160, 161 interposed between the gear 71' and the splined' sliding member or clutch plate .94.-

-A similar pair of collars 162, 163 are mounted on a sleeve of the sliding clutch plate 93,

the former preferably mountedithiireon and l".

'ed. to engage in different positions of adjustthe latter being non-rotativel-y'connected with the sleeve of the clutch plate 93 and fixed against Sliding longitudinally of the shaft 70. From the construction of the col lers 160, 161 and-162, 163 it-will be seen that by rotating the movable collar of each pair an action will be secured causing the clutch plates 93 and 94 to engage their counterpart clutch members 98 and 99 respectively with whatever pressure may be desired, under the control of the operator, for imparting movement in the desired direction to the traction devices operated by the gear 106 on the vertical 's haft107. No specific means are herein illustrated for imparting rotation to the movable members of the clutch shifting collar as same forms nopart ofthe present invention and the mode of operation of clutch shifting devices of this character are oldand well known to those skilled in the art.

' From the foregoing description of my im-' proved locomotive crane construction, and particularly the driving and power applying mechanisms connected with the swing body and the truck body, it will be seen that I' have simplified the construction of these parts of the locomotive crane making the same more economical to manufacture and at the same time providing for a simple and g satisfactory application of power for the various purposes required with a minimum amount of mechanisms involved, resulting in the elimination of a largenumber of parts of complicated and expensive mechanisms,

heretofore employed in constructing a machine of this character to function in the manner herein described. I have shown in. connection w th each feature of my invention the preferred mode of operation where there has been any departing from prior 7 and aceepted'art, but it is not desired to be swing body an, ear

iirnited'to the details described and illustratedexcept as defined by-the claims, for
