CARRIER ATTACHMENT FOR, BUCKET-ELEVATORS.
SPECIFICATION forming part of Letters Patent No. 478,322, dated July 5, 1892. Application filed April 25, 1892. Serial No. 430,485. (No model.)
To all whom it may concern.-
Be it known that I, MICHAEL GARLAND, of Bay City, in the county of Bay and State of Michigan, have invented a new and useful Carrier Attachment for Bucket Elevators; andl do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.
My present invention relates to-the means employed for connecting the opposite ends of the buckets, respectively, with the two endless cables in that species of bucketed elevatorin which a series of buckets or materialreceptacles is arranged intermediately of and is carried by two endless sprocketed cables which travel in unison over two sets of sprocket-wheels. I propose to providefor use a combined cable-clam p or cable-sprocket and attachment device by means of which in the species of elevator mentioned may be performed the duplex purposes of properly connecting the ends of the buckets to the traveling cables and efiecting the proper positive engagements between each 'of the endless cables and the pair of sprocket-wheels with which it is combined; and'to this main end and object my invention may be said to consist in the novel construction of combined cable-clamp or sprocket and carrier attachment hereinafter fully described, and that will be found most particularly pointed out in the claims of this specification.
To enable those skilled in the art to which my improvement relates to make and use bucket-elevators containing the same,I will now proceedto more fully explain my invention, referring by letters to the accompanying drawings, which form part of this specification, and in which I have shown the inven tion in that form inwhich I have so far successfully practiced the same.
In the drawings, Figure l is a partial front view of a bucket-elevator such as I have built and put into practical operation containing my present invention. Fig. 2is a partial side view of the same. Fig. 3 is a perspective view (enlarged scale) of one of the combined sprocket like and attachment devices detached. Fig. 4 is a detail cross-sectional view at the line 00 ac, Fig. 3.
In the several figures the same part will be found always designated by the same letter of reference.
A and B are the two endless cables of the elevator, which arearranged to run in unison, each being mounted on a pair of combined rope and sprocket wheels, the shaft of one of which is a drive-shaft, all in a well-known manner andnot necessary to be shown.
C are the trough-like buckets or oblong receptacles for carrying the material to be handled, each of which may be made after any approved constructionas, for instance, with cast-iron heads or ends and a body portion of sheet metal or boiler-iron bent into the desired shape and securely fastened to the cast head-plates or after any other mode of construction. Each end plate or head of each bucket (whatever may be the form and detail structure of said receptacle) is perforated for the reception of certain bolts, by means of which said end plate is securely (but removably) fastened, as will be presently explained, to one of the attachment devices D, (see Figs. 1 and 2,) the peculiar and novel construction 'of which I will now describe.
Referring now more particularly to Figs. 3 and 4, it will be seen that the device D is composed of two castings E and G, the firstnamed (and larger) one of which has an integral flange-like or plate-like part e, that is approximately triangular in contour and has in it three circular perforations F, each of which has a square countersunk portion, as at g, while the two castings have semicircular depressions that match together when the castings are in juxtaposition to form a housing for the cable, onto which said device D is clamped. The part E is also perforated with two round holes, which run in a direction transverse to the cable-housing depression and which pass on either side of the latter, while the smaller casting G is similarly perforated with holes that are in line with those of part G, and through these holes of the two castings pass the screw-bolts h, which at their .threaded ends are provided with nuts 1', as
seen best at Fig. 3. By means of the bolts h and their nuts i the two castings or parts E and G of the device D are secured together and are at the same time clamped round about the cable to which said device is fastened.
The heads of the bolts h are countersunk 3,) have their heads seated in the countersinks or depressions g, and are provided at their threaded ends that pass through the bucket end with suitable nuts.
As will be seen by reference to Figs. 1 and 2, those portions of the two castings E andGi which are in close proximity to the cable clamped between them perform the function of a sprocket-like device to coact with the sprocketsof the wheels over which the cable passes, and hence the form or shape of the castings in eross section, as-shown at Fig. 4, mustbe such that they will properly mesh or run in engagement with the toothed portions of the combined rope and sprocketwheels over which the cables of the elevator have to run. These teeth or sprockets of the said wheels maybe laid out according to any desired pattern; but whatever be their design and the pitch of the wheels the shapein crossseetion of each of the devices D and the spacing of these devices on the cable must of course be made accordingly.
Of course the size, proportions, and thetpattern (in some particularslof the devices D may be varied more or less, according to circumstances andwithin the judgment of the skilled mechanic, without departing from my invention, the pith of which lies in a combined cable-sprocket andattachmentdevice adapted tomesh with anordinary combined rope and sprocket wheel and havinga plate-like portion adapted to be bolted or otherwise fastened to a bucket headtor end which lies and travels in a plane parallel to that in which are located the wheels of the double-run elevator.
Itwill be seen that by letting in the heads of the bolts by which part c is bolted to the bucket-head the attachment devices D have no projections that might interfere with the wheels during the passage of the devices D around said wheels, and it will be understood that, made substantially as shown, these attachment devices D are not only perfectly efficient for the two purposes described, (that of engagement with the sprocket-wheels and that of supporting and carrying the elevatorbuckets,) but they are simple and economic of manufacture, strong, light, and durable.
The detachment and reattachment of a bucket from the twin cables which carry it may be easily eitected without disturbing the relationship of the devices D with their cables,
or these devices D may be detached from the cable without disconnecting the pair of attachment devices from the bucket they carry.
Having now so fully explained my invention that those skilled in theart to which it appertains can make and use elevators containin g my improvement, what Iclaim as new, and desire to secure by Letters Patent, is- 1. In an elevator of the type shown andidescribed, the combination, withithe twin cables and the buckets arranged between them, of
combined sprocket-like and attachment devices D, each of which is made in two parts and is provided with means for clamping said parts on a cable and each of which has one of its parts formed with a plate-like portionlocated intermediately of the two cablesand adapted to be fastened to i one end of one of the buckets of the elevator, substantiallyas set forth.
2. In an elevator of the type shown andidescribed, the combined sprocket-like and attachment devicecomposedof the two parts E and G, the first-namedione of which has an integral plate-like portion e and whichiare provided with the bolts-and nuts h t', as described, and which also has its said two parts properly shaped in cross-sectionin the direction shown to perfectly mesh or work in engagement with the teeth of the sprocket-wheel of the elevator, all as hereinbefore set forth.
In witnesswhereof I have hereunto set my hand this 25th day of March, 1892.
MICHAEL GARLAND. In presence of Messrs L. COURTRIGHT, SAMUEL LANDAU.
