Referring to the drawing in detail, the device of the present invention comprises generally a boom a adapted to be mlspended from a travelling crane or derrick (not shown); `a pair of carriages b adjustable longitudinally of the boom andv carrying chain c; and means operated by the hand wheel d for simultaneously moving the carriages b in opposite directions on the boom a.
The boom a is formed of two angle 1ron vbeams 10 positioned with their horizontal webs extending in opposite directions. The vertical webs of the beams 10 are secured together by bolts 11 and are spaced apart by sleeves 12 positioned. about the bolts between the beams. Each of the carriages comprises a hollow body portion 15 receiving the boom a and carrying at each side rollers 16 which travel on the trackways formed by the horizontal webs of the boom. Attached to the bottom of each carriage is a plate 18 each end of which is provided `with a hooked portion 19. Attached to each of these plates 18 are one or more chains c,
`the same time, if desired.
p Each of the carriages b is provided with an ,ear 20 movable in the space provided between-the two angle irons 10 of the boom and connected to these ears are racks 21 meshing with a pinion 22 fixed to a shaft 23 located centrally of the boom and carrying on its outer end the hand wheel d. lt will be seen that upon turning the hand wheel d, the carriages will simultaneously travel in opposite directions on the boom a and thus the distance between the carriages may be quickly varied to accommodate different lengths of rolls or other articles to bel transported. The'racks 21 are maintained in meshing relation with the pinion 22 by rollers 24. The boom is reinforced by plates 25 through which the shaft 23 extends.
Connected to the boom a by means of the shaft 23 is a yoke e composed of a pair of side plates or arms 27 anda cross member 28 carrying an eye-bolt 29 which receives the shaft 23 is suficiently great to prevent accidentalrotation of the latter.-
A roll` ot paper y may be connected to the chains c by bars f positioned in the ends of the opening or core of the roll. Heretofore, bars of this sort, owin to the weight of the paper rolls and the leverage exerted, fre uently resulted in mutilation of thepaper a out the openings receiving the bars or in breakin down the cores w where the paper is rolle on such cores. The bars of the present invention are constructed to obviate this dificulty. Each is provided with a relatively long spindle entering the opening of the core of the roll of paper. rlhe opposite ends of each spindle are similarly tapered in opposite directions as at 33, 34, so that relatively long substantially parallel bearing surfe/ces between the core tot wall and the spindle are obtained thereby greatly lreducing likelihood of cracking or breaking down the wall of the opening. 0n the protruding end of the bar is a grooved head 32 about which passes the chain c. The spindle portion is considerably longer than the protruding end `of the vbar so as to reduce leverage.
It 1s, of course, obvious that my invention 1s susceptible of varlous modifications and changes which are within the spirit of 4ways for adjustment and adapted to support an article therebetween, a manually rotatable shaft journaled centrally of said boom, a pinion fixed on said shaft, and oppositely extending racks connected to said carriages and meshlng with said pinion.
y 2. In an apparatus of the class described, a boom comprising. a pair of beams connected in spaced apart relation, a pair of carriages adjustable 'on vsaid boom, and means located between said beams for moving said carriages in opposite directions on sa1d boom. A
3. In an apparatus of the class described, a boom comprising a pair of channel irons connected togetherin spaced apart relation, a pair of carriages adjustable on the tracks formed'by the horizontal webs of said boom,
a pinion located between said beams, oppositely extending racks connected to said carrlages between said beams and meshing with said pinion, and a. hand wheel for rotating said pinion.
4. In an apparatus of the character described, a boom, a pair of carriages adjustable thereon, means including a shaft journaled in said boom for moving said carriages longitudinally of 4said boom, and an vattachment connected to said shaft for lifting said boom, said shaft being held against accidental rotation when the apparatus is lifted owing to the friction between the shaft and the bearings in which itis mounted.
5. In an apparatus of the class described, a boom,l provided with trackways, a pair of carriages adjustably mounted thereon, a manually rotatable shaft journaled in bearings in said boom, a pinion thereon, oppositel)r extending racks connected to said carriages and meshing with said pinion, and a yoke straddlin said boom and connected thereto by sald shaft whereby rotation of the shaft is prevented when the apparatus is lifted. l
l 6. In an apparatus of the cla described, a boom, a pair of carriages thereon and each having a pair of hooked portions, a pair of chains connected to each vcarriage an'd each having a hook on its free end adapted 'to be hooked over the hooked portions of said carriages. l
7. In an apparatus of the class described, a boom, a pair of carriages thereon and each provided with a depending platehaving hooked ends, a pair of chains connectedto each `plate and each chain having a hook `on its free end adapted to be hooked over the hooked ends of said lates.
