Description

rrn rats ANT . KARL S. HOWARD, OF ST.
LOUIS, MISSOO'RI, ASSIGNOR TO COMMONWEALTH STEEL COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF NEW JERSEY.
TRAVELING CRANE.
Specification of Letters Patent.
Patented June *7, 1921.
Application filed. October 27, 1919. Serial No. 333,741.
To all whom it may concern Be it known that-l, KARL S. HOWARD a citizen of the United States, residing at Louis, in the State of Missouri, have 1nvented a new and useful Improvement in lraveling Cranes, of which the followlng is specification.
My invention relates to a traveling crane in which the transmission shaft is driven by an electric motor, and has for its object to insure the perfect meshing of the pinion 0n the motor-shaft with its engaging gear on the transmission shaft at all times.
.Ordinarily, crane is mounted in brackets fixed to the VGltlOll web plate of one of the bridge girders and the motor with its appendages on a separate bracket attached to a different part of the said web, whereby, owing to the yielding of these separate parts of attachment the pinion 0n the motor shaft is not always in perfect engagement with the gear on the transmission shaft.
lhe invention consists in features of novcity as hereinafter described and claimed, reference being had to the accompanying drawing forming part of this specification, whereon,
Figure l, is a side elevation of one of the bridge girders of a traveling crane, broken away, and showing the support forthe electric motor and combined support for the transmission shaft according to my invention; 2, a transverse section of the same on line 2, 2, in Fig. 1, and Fig. 8, a cross section through the transmission shaft on line 3, 3, in Fig. 1 looking to the right and showing the combined support broken away.
Like letters and numerals of reference denote like parts in all the figures. I
a, a, represent the two parallel girders (broken away in Fig. 1) of a traveling crane to one of which (the girder a in the present case) is fixed to the vertical web plate 1 thereof at suitable mtervals along the transmission shaft of the the same a series of brackets I) having respectively a bearing 2 for the support of the transmission shaft 0 which operates the traveling gears of the crane in the usual well-known manner.
On a bracket d attached to the vertical web plate 1 of the girder a is mounted and fixed an electric motor 6 and on the shaft 3 of the motor '6 is fixed a pinion 4: which is adapted to engage with a spur gear wheel 5 fixed on the transmission shaft 0 in the usual well-known manner, the said pinion and wheel being omitted in Fig. 2, except as indicated by their dotted pitch lines.
In carrying out my invention, 1 form in the projecting arm or member 6 on one side only of the bracket d, preferably in close proximity to the spur gear wheel 5, a bearing f for supporting the transmission shaft 0 which passes therethrough.
' By this construction the motor 6 and transmission shaft 0, instead of having separate supporting brackets attached to clifferent parts of the vertical'web plate 1 as in ordinary practice, are both supported by the single bracket (Z and the bearing f being in close proximity to the spur gear wheel 5, the transmission shaft 0 is maintained at the proper distance from the motor-shaft 3 and the perfect engagement of the pinion l and spur gear wheel 5 is insured at all times.
I claim:
In a traveling crane of the character described, the combination with a motor and a transmissionshaft, of a bracket fixed to the framework of the crane and adapted to support the motor, a pinion fixed on the motor shaft, a gear wheel fixed on the transmission shaft and adapted to be engaged by the said pinion, and a bearin in the said bracket for the transmission shaft, the said motor being detachably secured to the
