TROLIQEVY-HOIST.
To. an whom it may concern: 2 I
Be it known that I, EDWARD Y. MOORE, a citizen of the United States, residing at Cleveland, in. the county of Cuyahoga and,
State of Ohio, have invented a certain new and useful Improvement in Trolley-Hoists,
' of which the following is a full, clear, and
i so
a I so exact description, reference being had to the accompanying drawings.
The primary object of this invention is to provide atrolley or trolley hoist adapted to run on a, trackway and having the capacity to swing the load support to either side of the trackway. The mechanism has manynses where it is desired to convey a load and; support it in a position which may not be exactlyunder the trackway My mechanism may Well be embodied with raising mechanism, thereby constitut- 'ing a trolley hoist.
The invention includes not only means for swinging the'load support'to either side of the trackway, but also means for locking it in any swung position, and means'for i rounding this stud is asleeve 32, from which extends a projecting portion 33, which forms a part of the frame of the hoistL clamping the trolley to the track." I I The supporting of the hoisting mechanism attwo points, one being swivel and the other a travelingroller, is also one of the features of this invention.
Other features are also included, which will be hereinafter more fully explained.
The drawings illustrate my invention as embodied in the trolley hoist. Figure. 1 is a side elevation of such mechanism; Fig. 2 is a front or end elevation; Fig.3 is a ver tical central section on a plane parallel with Fig. 1 Fig. fl is a sectional plan, thesection plane being located just below the track, as indicated by the line 4l& of Fig. 1;
Fig. 5 is a horizontal section in a plane just above thetraveling supporting roller, as indicated by the line,5--5 of Fig. 3, the arcual track for. the roller being omitted for clearness of illustration.
The supporting trackshown comprises a usual I-beam having a web 10 and projecting flanges 11. Riding on the flanges of the I-beam are the trolley wheels 15, which are shown as mounted on studs 16 projecting from brackets 17, of an inverted U-shape. These brackets are secured near their lower ends to the trolley frame 20 by means of rods 21, which extend through the brackets and through cars 22 on the trolley frame. Rigidity between the brackets and trolley [specification of Letters Patent. t n d Dee, 29, 1914. Application filed May 19, 1910. Serial No. 562,123.
frame is provided by cap-screws 23, screwing through the projecting portions .24 of v the brackets into the trolley frame. The
rods 2lmay be prevented from displacement by ,pins"25 driven through them. The descrlbed construction is'avery strong and eifectiveone for connecting the supporting Wheels with the trolley frame, and, at the same time,q,allows the parts to'be easily assembled and disassembled. The driving out of thepins 25 allows the rods 21 to be drivenout of the ears and the removal of the cap-screws 23 completes the separation. By
reason of the U-shape of the brackets upon which the supporting wheels are mounted, the trolley may easily pass around curves .or through switches, as shown, described and claimed in my prior application #5417 ,001. This ease of passage is enhanced by having the legs of the brackets 17 elliptical in cross section, as shown inFig. 4.
As shown more particularly in Fig. 3, on the under side of the trolley frame 20' is a Idownwardly extending boss 30, in which is rigidly mounted a vertical stud 31.- Surnechanism, or other load, support, as hereinafter explained. In the bore of the sleeve,
and36, and'belo'w the sleeve and the bushing 36 is a washer 37 ,and below thiswasher is a nut. 38 screwing onto the lowerendv of the stud and pinned'to it. The sleeve and frame member 33 is thus swiveled on the stud. 1
Rising from the swinging frame 33 is an arcual track 13, provided by the segmental and bearing on the stud 31, are bushings 35 flange extending inwardly from the lower edge of thewfront vertical wall 44 of the frame 20. The load is supported by suitable mechanism mounted inv plates 50 and5l,
which are secured by bolts 52 to the swiveled member 33. Accordingly, it results that the 1 load is supported at two points; namely, by the swiveling stud and the roller 42, and this eliminates lateral strains in the swivel.
' When the sleeve 32 is turned on the stud 31,
the wheel 42 travels on'the flange 43, and the load supporting mechanism is accordingly shifted to one side or the other of the track way. I
The carrying of the load to either side of I v Y 1,122,295

support, is one of the important features of this invention. When the load is so carried to one side or the other, it tends to tip the mechanism downwardly on the loaded'side.
17, on the opposite side from the load, engaging the under side of the trackway. These lugs, accordingly, not only prevent material tipping of the mechanism, but automatically lock it inposition when the load is at one side or the other of the center.
-Thoug-h the load maytravel'a considerable distance to. either side, it will benotedthat it never passes out of the space between the transverse planes'through the centers of the supporting wheels, so that there is never any tendency to tip the mechanism endwise.
To conveniently swingthe swiveledframe on the stud andlock it in any desired position, I provide a worm-wheel 60, which is keyedto the sleeve '32 and meshes with a worm6'l, ona shaft 62, which hasa handchainewheel 63. -Accordingly, the rotation of this hand-chain-wheel swings the hoisting mechanism, or load supporting mechanism, to either side of the track, as desired, and automatically looks it wherever it is left, The shaft 62 0f the worm is jo-urnaled in the bosses 65 and 66, extending downwardly from the upper portion of the frame 20, and providedjwith suitable caps 67 on their under sides,'sec-ured by cap-screws 68. The range of movement oft-he swiveled structure is limited by the stop-screws 57, screwing downwardly through the frame QOinto posi- 7 tion to stand in the path of the car 39, which carries the stud for the roller 42. a
I any'form desired, either a simple supporting The mechanism for supporting the load carried by the plates and 51 may be of mechanism or-ahoisting mechanism. The latter is the form shown herein, and may be briefly described as consisting of a drum 70 mounted on a stationary sleeve 71 and having a gear 72 which meshes with a pinion 73 on the shaft 7a, which shaft, in turn, carries a gear 75meshing with a driving pinion 76.
This latter pinion is on the end of a shaft 77 which-passes through, and loosely occupies, the" sleeve 71, and, at its other end, carries a hand wheel 78, whereby it may be rotated.
The connection between the hand wh-eel'anol shaftmay, if desired, be of a ratchet and brake nature, as illustrated in my Patent #797,997, whereby the hoisting mechanism is self-locking, but the load may be lowered, by keeping the hand wheel ahead of the position given the shaft 77 by the descending load.
Having thus described my invention, what I claim is 1. The combination of a depending trolley frame, supporting wheels carried thereby, a load supporting member, a swivel connection between the same and the trolley frame adapted to partially support the load, a trackway on the trolley frame and a roller on the load supporting member, whereby the load may be swung to either side of the track, means for confining the range of such movement to the space between transverse planes through the axes of the supporting wheels, and hoisting mechanism carried by said member between the swivel and roller.
2. The combination, with a trolley frame and supporting wheels, of a bracket for carrying one of the wheels, a rod for pinning said bracket .to the frame, and a screw passing through an extension of the bracket into theframe. 1
3. The combination, with a frame, of a U-shaped bracket, a pair of supporting wheels carried thereby, a rod extending through the legs of the bracket and through ears on the frame, and additional means for securing two legs of the bracket to the trolley frame. a
4. The combination, with a frame, of a U-shaped bracket, a pair of wheels carried thereby, a rod extending through the legs of the bracket and through ears on the frame, and lugs projecting inwardly from the legs of the bracket and adapted to stand beneath the flange of an I-beam on which the wheels ride.
5. The combination of a wheeled trolley frame, a horizontal arm pivotally-mounted on the trolley frame and adapted to swing in a horizontal plane, a roller and trackway, one of which is carried by the arm and the other by the frame, a hoist carried by the arm, and self-locking mechanism for swinging the arm in either direction.
In testimony whereof, I hereunto aliix my signature in the presence of two witnesses.
