Fig. 10 is a section on line R-R of Fig. 9 with sliding collar t7 omitted; Fig. 11 is a section on the line S-S of Fig. 10; Fig. 12 is a. section on the line T T of Fg. 10, looking to the right; and Fig. 18 is a section on the line T-T of Fig. 10, looking to the left. o

In carrying out the invention any preferred form of nonstruction of parts may be employed so long as they possess the necessary characteristics, but 1 have shown one arrangement which is effective, and in this embodiment 1 represents the supporting wheels which are arranged in the usual -manner upon axles 2. Each of these axles is providedv with a hevel'gear 3 which meshes with a bevel pinion Ll mounted upon a longitudinally disposed shaft 5 supported in hearings 6 secured to the underside of the truck frame 7. Near the center of the truck the shaft 5 is provided with a driving gear 8 meshing with a pinion 9 carried by a shaft 10 supported in a bushing 11 arranged in the ing 19 forming part of the bed. The upper end of this shaft is provided with a bevel gear 20 meshing with a driving pinion 21 supported upon a shaft 22 mounted in bear- 95.

ings 23 projecting upward from the hed.- The forward end of this shaft 22 is vided with a main driving bevel gear 24e receiving power in a manner to 1oe described.

Projecting upward from the main bed 13 are two side frames 25 provided with bearings for supporting a main power shaft 26, a drum shaft 27 and the boom heel pins 28. Power shaftu26 may he driven through the usual connections from a steam engine,.in ternal combustion engine, electric motor, or any other vdesirable prime mover. An A- frame structure consisting of two posts 29, one on either side, with tie rods 30 securely anchored to the bed 13, serves to support the head end of the boom 31 by means of a rope 32 which is reeved back and forth over prosheaves supported on n transverse pin nt the poul( of the A-frume, und shenves 35 secured to the hooin hemd pin 3G by links lli. The rope 3Q hns one end secured to the linlis nt while the other end is seefied to aiy windingdrinn Il?) inounled on shalt Z7 so that when the drinn is rotated in e direction to wind or unwind the rope, the heed end ot the boom is raised or lovvcreil respectively.

From a ivini'linp; drinn el() on shaft 2i e loud hoist rope -ll runs over n sheiive 42 mounted on pin 3G und carries e hook or other suitable niczins for supporting the load il.

T he innin driunlslnilt '27 carries the Winding drums 3S und ll() und gears l5., both drums und `gears heinpd tree to turn on seid shnlt. rthe drunis nre each provided with friction l'lungcs 4G adapted to receive brake bands 4J und clutch bands lil. The gear l5 is driven by n pinion 19 keyed on the povver shaft Q6. und in turn drives its respective drinn by n clutch inechnnisin comprising the hund i8 which carried by the gear and :nlnpteil to he tightened About the 'friction tlnnge lo therehjT applying; :1 clutching nc- `tion between the driving gear und Winding drinn,

Referring to llig's. 5. il, und 7, the deed end o'l the clutch hund l-S is anchored to u pin 50 carried by the `neer l5. and the live end is connected through n rightnnd lei't 'ndjustiner nut 51 to the erin of n rocker 53 having n fixed pivot pin 5l held in the geur ineinlier. The rocker is operatively connected to n slidingr sleeve 55, Fig. l, by n. i'iniversul-joint linkage 56. levers 57 und 58 keyed to the she'lt 5S), :1nd links G0, Fig. el. The shnlt 59 hnsfbenrings G1 in the geur ineinher. The sleeve 55 is mounted on the extendeilhnlo ol' the gear Ll5 and univ be moved in :1nd out along the unis ol' the slniit by :inv of the veriousrneens eonnnon in practice.

From the construction it is seen that n inotion of the sleeve inward e., ovv-uv from the side hearing 25, results in :i clockwise rotzition of the rocker 53, thereby tightening the bend und applying its clutching notion; While@ motion or' the sleeve outward results in e posit-ive release oi the clutch.

Brake bends e? nrc provided for sustaining or lowering the loads when the clutches i3 :ire released. Referring to Fig. 7, the dead end of the hund is anchored :it 62 to the rotating hed structure 13 und the live end is connected through the right and left adjusting nut 63 to one nrln of u hell-crnnlr lever 6l having :L fixed fulcruin nt (35 in the hed 18. 'toot pod 66 connected et 67 to the otheriirni of the bell crunk is utilized for operating the brake, :i motion downward of the paid resulting in tighteningl the bond und applying thelorele in :i vvell linovvn manner. '.lhc power shaft 2Gy carries keyed to it the lnusniueh as these four clutch mechanisms :ire similar in construction and operation u description ol one vvill suffice for all and this description will he confined to the clutch mechanism between the driving sleeve GS and und the bevel gear T3.

Referring to Figs. 9, 10, 11, 12 and 13, the driving, sleeve 68 is secured to the shaft 26 h v n lacy T6 and is provided with o radial vveh 77 carrying s. peripheral flange TS within lout less in diameter than the drum 75, and forming n support for o. clutch loand which is ninde up otl bund portions 79 and 80, each portion being provided at its lovver end, es shovvn in Fig, 1U, with nn enr Sl, the tivo eers receiving :i right and left hund iidjust ing screw 82. These hall" hund portions are held in piece lojY plates 83 secured to the sides ot the lzinge T8. Friction linings Sl are secured to the hond portions und are adopted to engage with the inner cylindrical friction surface of the drinn 75. These bend por tions, united by the adjusting screvv SQ? form :i continuous hand, the' free ends of which, as shown in Fig. 10, are each provided with on inwardly extending lug 85, the right hand end being anchored in :L recess 86 formed in the driving sleeve web .77, :is shown hy dotted lines in Fig. 10, while the opposite end engages in n recess 8'? formed in the end of a lever 88, which is pivoted upon s pin 89 secured in the web 77 at a point substantially diainetrically opposite to the socket 8'?, This lever extends 'bevond the pivotJ S9 and is provided with a. countcrvveight 90 und n release spring structure comprising en eye 91 engaging pin 92, secured to the end of the lever.l n spring seat 93 Yforming e part ot the eye and receiving the thrust of i compression spring 94e arranged upon e threaded rod 95 provided with an eye 9G engaging u pin 97 secured in the web 77. in adjusting nut 9S serves as e. means for varying the compression of the sprin'. 'llhe web 77 is provided et a point near the deed end recess Sli with u friction roller pocket 99 adapted to receive e :friction roller 100 mounted on a, pin 101 shown in full lines in Fig. 9 and in dotted lines 1in Figs. 10 and 12. Gpposed to this roller and arranged in the end of the lever SS adjacent to the recess 87 is another frietion roller pocket 102 adapted to receive a friction roller 103 mounted upon e pin 10e,

shown in dotted lines in Figs. 9 and 10. The rollers 100 und i055 are opposed to each other und adopted te engage on opposite sides of e wedge 105 which is secured to the sliding @nearer collar 106. The pocket end of the lever 88 is provided with a pair of ears 107 and .108, which receive a tongue 109 formed on the sleeve lia-nge 7 8, and serve to hold the lever in proper alinement.

From the foregoing it will be seen that when the Wedge is Withdrawn from between the rollers the spring 911 will move thelever 88 in a clockwise direction and contract the band upon the flange 7 8, when 'the clutch mechanism will be free to rotate without driving the drum 7 5. Wien the wedge is 1nserted betweenv the rollers the band is eX- panded in a Well known manner andthe drive is transmitted to the drum. I

Referring to Figs. 3 and 12, the sliding collar 106 carries tivo Wedges 105 and 110 adapted to operate the inside pair of clutches which drive the gears 73 and 74. as the collar is shifted to the left or right respectively of its central position by means of the forked lever 111 fulerunied at 112. The sliding collars 113 and 11d each carry a single Wedge and are adapted to operatethe outside pair of clutches which drive the gears 71 and 72 respectively. rhese two collars are operatively connectedby forked levers 115 and 116, fulcrumed at 117 and 118, and link 119, so that they are constrained to move in unison and in the same direction. When the sliding collars are in their central positions as shoivn in Fig. 3, the clutches are all released and the gears 71, 72, 73, and 74e are free to turn upon the shaft. A movement of the `eollars to the right or left results in driving. one gear of the pair While the other remains free to turn upon the shaft.

The power shaft is in alinernent both with the vertical propellin shaft 19 and vvith the horizontal rotating s aft 22. The outside pair of bevel gears 71 and 72 are in mesh with the bevel gear 12 which drives the proelling mechanism, While the inside pair of iievel gears 7 3 and 741 are in mesh with the bevel gear 52a which drives the rotating mechanism.

From the foregoing description it will be seen that the folloiving operations can be performed when the power shaft 26 is driven in one direction of rotation. The crane can be propelled along the track in either direction by engaging the proper clutch bevel gear 71 and 72. Ehe bed can be rotated in either direction by engaging the proper cli tch bevel gear 78 and 74. The load can be hoisted or lowered by means of the clutch and brake bands which engage the Winding drum d0. The boom can be raised and lowered by means of the clutch and brake bands which engage the Winding drum 39. 1t is further to be noted that all of the above operations are independent of each other.

lifhe particular feature of the construction to Which this invention relates is the novel arrangement of the mechanism mounted on the power shiaft 26. The gears 71 and 72 with their clutch @mechanisms compose one independent reverse driving unit adapted to convoy direct and reverse rotary motion to the Wheels supporting the truck, While the 'gears 7 3 and 74 With their clutch mechanisms conipose a second independent reverse driving unit adapted to convey direct and reverse rotary motion to the bed. Gther features of the construction are relevant only in so far as they enter into the several combinations as set forth in the following claims.
