Application med November 15, 1926. lSerial No. 148,534.

My invention relates to improvements in hoisting apparatus. i

In accordance with my invention, I. provide a portable hoisting apparatus, which 1s particularly well adapted for use in working upon railway locomotives, for removlng parts therefrom and placing the same thereon. The hoisting apparatus may be manually operated and has a wide range of adjustment, whereby it may handle parts 1 n portions of the locomotive which are ordinarily inaccessible. The ap aratus is so constructed that the load may e carried at one side of the machine, without liability of the machine tipping over. I also provide means which is. adjustable upon the running board of the locomotive, over whichthe extension mast may project, and having guide means for the cable, thereby preventing injury to the cable and running board.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification, and inwhich like numerals are employed to designate like'parts throughout the same,

Figure 13 is a horizontal Section taken on line 13--13 of Figure 1, parts omitted, and,

Figure 14 is a transverse section taken on line 14-14 ot' Figure 3;

1n the drawings, wherein torthe purpose ,'downwardly.

of illustration, is shown a preferred embodiment of my invention, the numeral 15 designates a carriage frame, preferably tapered forwardly, as shown. The rear end or this frame is supported bywheels 16 carried byy an axle 17, the ends oi which are journaled in the ends of the frame 15. Near its forward end, the converging ortions of the frame have connection wit a transverse plate or web 18, welded or otherwise rigidly attached thereto which is pivotally mounted upon a forward transverse axle 19, the intermediate portion of which is preferably bent llhis axle carries wheels 20, which may enter openings or notches 21, formed in the sides of the carriage frame 15, duringthe steering operation. The forward axle 19 is steered by means of a tongue 22, suitably secured thereto. The carriage frame 15 is longitudinally inclined and extends downwardy towards itsreduced forward end. The extreme forward end ot .the earriage framel is in the form of a socket having spaced parallel sides 23, as shown.

The numeral 24 designates the lower stationary element of an extension mast. The lower mast element 24 is tubular, and is preierably rectangular in cross section although it may be circular or in any other desired shape. The lower end ot' the mast section 24 is arranged within and between the sides 23 and is welded or rigidly attached thereto. Rigidly attached to the lower' portion of the mast 24 are curved braces 25, diverging rearwardly for rigid attachment to the sides ot the carriage frame 15, as shown. The mast section 24 is inclined toward the rear elevated end of the carriage frame.

. Slidable within' the mast section 24 is an upper mast section 26, in the form of a rack bar, having a longitudinal set of teeth 27. These teeth are adapted to be engaged by a gear or pinion 28, Figures 1 and 7., operating through a slot 29. This gear is carried by a transverse shaft 30 supported b plates 31, which are rigidly secured to tie opposite sides of the mast section 24. The gear 28 is driven `by a larger gear 28 engaged and driven by a smaller gear 82, which is rigidly mounted upon a Shaft 33, turned by a handle or crank 34. The reverse turning mmvenient of the' gear 32 is prevented by means of a. pawl and ratchet device 35.

In View of the foregoing description it will. be seen that the upper mastsection 26 may be raised or lowered by turning the handle Section .or crank 34;, and may be locked in. the adjusted position by manipulation of the paivl or dog 35. y

The .mast section '26 is provided at its upper end with a horizontal overlianging arm 36, preferably formed integral there. with. Mounted upon this arm to travelv longitijidinally thereof and to be projected beyond the same is an upperco-acting armvi'. rlllie arm 37 is :provided with a pair ot guide plates 38, rigidly attached to its rear end, and having a roller 39 mounted between them and suitably attached thereto.. rl`his roller engages the lower edge ofthe ariril'. The arm 36 is provided at its rear end with a. recess, within which is rotatably mounted a roller 39, projecting slightly above the upper arm 36 and supporting the arm 37. Ehe arm 36 is provided with a pair ot depending plates 40, rigidly attached thereto and these plates are disposed upon opposite sides of the. arm 3G and have notches lll, which receive the axle 42 of the roller 39, and limit the outward movement of the arm 37.

iigidly attached to one plate 38 is a box et, hai/ing a screw-threaded opening, for re* ceiving a sereiwthreaded feed .rod de, the 're-ar smooth end ot which is rotatably mounted Within, a lug oi' ear rigidly attached tothe top ot the mast section :26. Logs Llli are rigidly attached to the 'rod el, and Anotate upon opposite sides of the lug e5. 'lne iforward end oi' the scieiv-tlire.a led rod flat is square tor engagement with a suitable Wrench; thus seen that `means are prf 'vided 'for shifting the ai'iii 37 longiii'idiiially with relation to the arm llf.

Suitably mounted. within the forward. end

ot the arm 37 is a sheai'e fifi', engaging a cable fill, which einployefl to raise and lower the object. l he cable extends forwardly and passes over a guide sheavo l), mounted in a bracket 50, .vliiirl'i is attached to .the rear end oit.' the arm El?. 'llie cable extends Vliorii'ardly :from this point and passes about a sheavc 5l. mounted. in brackets `which are attached to the rear end. oi the ai'iii then -eXteiii-ls do'iviiwaidly, generally parallel. with the mast sections 254i and QU and passes about a guide sheave 52, lmounted upon brackets 5B, rigidly attached to Vthe ,slieiive rlhe low-er end ot the cable is suitably attacheijl to a driiiii 54, which is ai'- ranged between brackets 55. and rotatal'ily mountedv thereon.- The driiiii isrigidi.'v atn taclied to a shaft 56, and this shaft is turned by a large gear 57, driven by a smaller gear 58. This smaller gear rigidly iiioiiiitcil upon a shaft 59, jouriialed in the brackets 53. The shaft 59 'may be turned by a crank o() oi' the likeyancl the rotation of the shalt 59 ina reverse direction is `controlled by suitable paivl and ratchet means (il.

l provide an extensionboom (S2, lor coactioii With the adjustable arms 36 and 3T,

l'i. The cable 4.8'

moet if? and which is adapted to loe projected va conn siderable distance beyond these arms. This boom comprises. a tubular boom -section 63 receiving a (1o-acting boom section 64 for slidable action therein. These boom sections are preferably elliptical so that there is no tendency for them to turn with relation to each. other. The boom section 63 is equipped with a housing 65, having a transverse shaft 66 journaled therein. This shaft has a gear .67 rigid thereon, operating through a slot 68,

for engagement with teeth .69, formed upon the boom section 64. The gear 67 may be locked against rotation by a set screw 70 or' the like. The shaft G6 is turned by means of a crank 7l or the like. 'it is thus seen that the hoorn section 6e may be shifted longitudi nally of the' boom. section 53, and when projected to the end ot its travel, it will be a. substantial distance in advance of the arm 37, when Such varm is projected to the end of its travel.

rlhe inner end of" the boom section (i3 is slotted, providing a forked ,end and this forked end includes a pair of spaced fingers 72. This forked end isadapted forv interlocking engagement with the forked end 73 oliva coupling 74. The fingers 72 are provided at their forward ends with openings for receiving a bolt 'l5 also passing through an opening 76 in the coupling "(Li. The tree end of the coupling passes between spaced ears or knuckles 77, rigidly attached to' the mastsection 24,' and these ears are apeitiired for receiving a bolt 78, passin i throughmar opening 79m the rear end ol tie coupling! il.

At 'its :forward end., the boom sect-ion (il carries a guide sheave 80. rl.`he boom sections are supported by a suspension element, such as a chain 8l, which may be suitably adjustablv secured tothe boom section G3. rl'liis chain extends upwardly and lis suitably ate` tached to the arm 36.

it is sometimes desirable to `suspend the boom 62 at an elevation above the loiveiI mast section Q4 and when this `is to, lio done, the forked end of the boom section G3 -is ilet'ached from the coupling 74, and this forked end is inserted upon the upper minst section Q6, Figure 13. The end ot' 'the tubular boom sectioi'r G55 interlocks with the teeth 27. while lill RMS

the fingers 72 extend-upon opposite sides of A the mast section 2G. The bolt T5 is employed to connect the li'ee ends oit these ingersand :i Wedge S9 is preferably employed to .be driven between the bolt T5 and the edge of ythe ,mast

section (Sil with the teeth 27.

lVheiiit desired to remove/air.cylinders or otliei-i'oiind objects from thelocoii'iotive, the boom (S2 may be' ieiiioved i'ioin the hoisting mechanism, and the attachmentshown in Figures 8 and l0 substituted therefor. This attachment embodies a sliaiil( 83.y carrying outwardly direi-ging ariiis Sl, the ends oi moans? which are curved at 85, to receive the air for interlocking detachable engagement with the coupling 74, and is held thereto by the bolt' 75 passing through the apertures 91. Any other suitable means may be employed for connecting the attachment vviththe mast '..section 24, or'the mast section Q6, as may be requireth'it being stated that the forked end 90 is adapted to be mounted upon the mast secL tion 26 in a similar manner in which the forked end of the boom sect-ion 63 is mounted upon the mast section 26.

The numeral 92 designates/a carriage or body portion ot an adjustable guard, which is adapted for use in connection with my hoisting mechanism. The carriage 92 is adapted to be mounted upon the running board 93 of alocoinotive and extends transversely of the running board, and is adapted to be shifted longitudinally of the running board. The carriage 92 is provided at its inner end with a depending extension 93', and at its outer end with a depending extension 9,4. 'llie upper horizontal portion 92 of the car riage is supported by rollers 95,adaptedto run upon the top ot' the running board 93 and the depending portion 94 ispreferably equipped with vertical rollers 96, engagingthe edge of the running board. The numeral 97 desighates a sheave, arranged at the inner end of the carriage 92 and supported by a shaft 98. The shaft 98 is journaled in ear-ings 99, which are secured to the carriage 99.

The carriage 92 is adjusted longitudinally of the running board ot the locomotive, to the desired point. After this is accomplished, the arm 37 may be arranged upon this carriage 92, to be more or less supported thereby. The cable 48, passing to the work to be raised or lowered, is trained by the sheavc 97, and hence the cable and runnin board are both protected against unnecessaryv wear or injury.

The operation of the apparatus is as follows:

The 'mast section 2G may be first adjusted lo the desired elevation, and the horizontal arm 37 may be projected outwardly to the desired position. The entire apparatus is portable and may be shifted in proximity to the locomotive, and the adjustedarm 37 extended into the space within the locomotive. 'llie cable 48 may be attached to the part to lic raised, such as a spring, and by 'rotating the drum 54, the part may be readily elevated. The apparatus may be employed lo deliver an4 intermediate.

.an object to the: desired point of the locomotive. If it. should be desired to raise an objectr at a greater distance than caribe accomplished by projecting arm 37 to the extent of its movement, the boom 62 is employed. This armrmay be mounted either upon the mast section 24 or upon the mast section 26, as may be'r uired. The boom section 64 is now projectie forwardly lto the end of its travel and the cable passes over the sleeve 82, as clearly shown in- Figure 3. When` it is desired to remove air cylinders or the like, the boom may be removed from the machine land the cylinder manpulating attachment l shown in Figures 9 an 10 employed, as ex. plained. ,j
