Patented Feb. 17, 1931 ERNEST JOHN HITTLE, or cotuMBUs-omo SAFETY nors'rrive nnvron Application filed October 23, 1929; serial ma a.

This invention relates to cranes, and its genera-l objectisto provide a hoisting device that is primarilyfdesigned for handling trucksof railroad freight cars and the like --5 in an easy and, expeditious manner by a single XVOIkEDElIl withininirnurn efiort,

Another object of the invention is to provide a hoisting devicethat may be employed for handling any type truck for railroad 1 cars and thelike as well as any rolling structure that can be placedadjacent the device,

' .without fear. of slippage, falling or the like, with the result the devic e is safe and Will reduce damage. and injury'tomachinery and i t workmen.

A further obj ect of the invention is to provide a hoisting devicefof the character set forth, that is simple in construction, inex- *Ipensive to manufacture and install and extremely ,eihcient 1n operation andservice.

Thislinvention also consists in certain other features of construction and in the combinationland 'arrangement of the several parts, to be hereinafter fully described,

lustrated in the accompanying drawings and specifically pointed out in the appended claims." r

4 In describing my invention in detail, reference will "be had to the accompanying p drawings wherein like characters denotelike or corresponding parts throughout the several views,'and in which: is Q F igure'l is a side elevation of m hoisting device.

Figure 2is an end view thereof. a Figure 3 is a top plan view. 1

Figure 4 is a sectional view taken approximately on lined-4 of Figure 1, looking inthe'direction of the arrows. I I

- 1 Figure 5 is a sectional view taken approximately on line 55 of Figure 3.

Referring to the drawings in detail, the

reference numerall indicates a crossbar that niay besquare in cross section as best shown the converging uprights 3 which are ar- "ranged in pairs and have their upper ends cut away to fitthe cross bar as best shown in Figure 2. The converging uprights not only the uprights.

in Figure'e, and this cross bar has its ends resting upon strips 2 secured, to and between support the vcross bar 1, but are secured thereto through the instrumentality'of brace i rodstwhich are insreality angle bars'thathavetheir ends split at their juncture of'th'e respectivefian ges thereofso that one of the flanges of the lower ends, which for distinction; are indicated by the reference nuine ral '5, issecured to the outer sides of'the converging uprights, while the flanges 6 are bent at an angle with respect to the body of the brace rods and secured to theconfronting faces of These respective flanges 5 andfi at their lower ends are securedto the uprights through the medium. of bolt and nut connections as shown, jThe upper'ends 6 of the brace rods are likewise split longitudinally for a portion'of their length atqthe juncture of the respective flanges thereof, and these portions. are indicated by the reference numerals 7 and 8 The portions 7 are secured to the sidesof the cross bar 1, while the portions 8 which are bent atan angle with frespect to the bodies of the brace rods are se V cured tot-he underside of the cross bar, and

bolt and nut connections are employed as the securing means: V Y

Cooperating with thebrace rods tare cross rods 9. that extend transversely ofandthrough the respective converginguprights' of the pairs as bestshown in Figure 2-,;and 8 .these'cross rods 9- may have their end-por- V ti'ons threaded to .rece ivelnuts 10.

Secured upon opposite sides of-the cross bar 1 are plates 11 which have formed therewith flanges 12 that are secured to theupper .5

ends of the converging uprights, and these plates 11 as well'as the flanges12e'xtend be low the cross bar. It will be noted that these plates are arranged in cooperating pairs,

andhave journaled therein the trunnions 13159 of drums .14. The opposed trunnions of each -of the drums 14 have fixed thereto worm 3 gears 15 that have arranged in mesh there-- I with worms 16' the latter being secured to or formed with shafts 17 that are journaled in bearings 18. The shafts are disposed longitudinally of the cross bar 1, and have secured to the outer ends hand wheels 19. Each of the drums which fact are also arranged in 'pa1rs,-as best shown 1n Figure 1, have se ,PATENT ass-ICE] I 5; 3

ends of chains 20 and 21. It will be noted that the chains 20 which are secured to the innermost drums have secured to the lower ends chain sections 22 that carry hooks 28, while the chains 21 have secured to their lower ends hooks 24, and carried by one of the links of the chains 21 are rings 25 for the purpose of receiving the hooks 24:. v r

In order to further brace the structure, I: provide upon each side of the cross bar 1, truss rods 26 that have their ends passed through the converging uprights 3 and threaded to receive nuts The rods 26 are bent downwardly toward their centers at an inclination and across piece 28 which 'is bolted to the center'of the cross bar l extends beyond the sides 'ofsaid cross bar for engagement with the rods, the latter being disposed below the cross piece as best shown in Figures 1 and i.

From the above description and disclosure of the drawings, it will be obvious that I have provided a hoisting device that is primarily designed for handling trucks of railroad cars and the like, and the chain sections 22 can be secured about a truck through the medium of the hooks, while the chains 21 can be likewise secured about the trucks by the hooks 24 and rings 25. The hand wheels can then be rotated for lifting the trucks to the desired height whereby work can be done thereon as will be apparent. While I have set forth that my hoisting device is primarily designed for trucks of the character referred to, I want it understood that it can be employed for handling any machinery and the like that can be disposed within the radius of the chains, whereby the latter can be secured thereto,

It is thought from the foregoing description that the advantages and novel features ofmy invention will be readily apparent.

, I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claims.

What I claim is: V a

1. A; hoisting device comprising converging uprights arranged in pairs, across bar supported by said uprights, strips secured to said uprights and cooperating therewith for supporting the cross bar, brace rods having their ends split and arranged to be secured to the converging uprights andfc'ross bar,

respectively, plates secured to saideross bar and uprights, drums journaled between said plates, flexible elements secured to said drums, article. clamping means carried by said flexible elements, and manual operating means for rotating said drums.

remaining portions being bent at an angle with respect to the bodies of the'brace rods and secured to 'the confronting sides of the uprights, one of the portions at the upper ends of the brace rods'be'ing' secured to the outer sides of the crossbar, the remaining portions at the upper ends being bent at an angle to the bodies of the brace rods and being secured to the underside of the cross bar, article handling means supported with respect to the crossbar and operating means for said article handling means.

4. A. hoisting device comprising converging uprights arranged in cooperating pairs, a cross bar between said pairs of uprights and secured thereto, bracing means for said uprights, said bracing means including brace rods having split ends, one of the portions at the lower ends of the brace rods being secured to the outer sides of the uprights, the remaining portions being bent at an angle with respect to the bodies of the brace rods and secured to the confronting sides of the v uprights, one of the portions at the upper ends of the bracerods being secured to the outer sides of the cross bar, the remaining portions at the upper ends being bent atan angle to the bodies of the brace rods and. i being secured to the underside of "the cross i bar, truss rods having their ends secured through the converging uprights and bent downwardly toward the center thereof, a cross piece secured centrally of the cross bar and and extendihg beyond the sidesthereof for receiving the truss rods, article handling means supported with respect to'the cross bar; and operating means for said article a handling means." e In testimony whereof I affizr my signature.
