BOLTlNG-REEL.

SPECIFICATION forming part of Letters Patent No. 271,853, dated February 6, 1883. Application filed May 26, 1382. (No model.)

the accompanying drawings, and to the letters;

of reference marked thereon, which form a part of this specification.

Thisinvention relates to so-called iron bolting-reels,- which have heretofore been made to some extent in an eifort to obviate the faults found in similar reels of the ordinary wooden construction of frame-namely, a tendency to sag and to get out of shape in use or from be ing alternately run and allowed to stand loaded. Such distortion of the reel arises usually from its considerable length, being commonly or often eighteen or twenty feet long and having support only at the ends of its central shaft. In iron-framed reels heretofore made another difficulty has arisen from the expansion and contraction of the metal composing the frame in consequence of changes in temperature. This expansion and contraction, being uneven, has resulted in breaking the brace-rods, spokes, or other parts, and has practically led to the abandonment of iron-framed reels.

It is the object of my invention to provide a construction of an iron-framed reel which has the advantage of preserving its original form and truth, and in which provision is made for the expansion and contraction of the metal parts withoutdanger of breaking.

H To this end the invention consists in the matters hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a longitudinal section of a bolting-reel containing my improvements. Fig 2 is an end elevation thereof. Fig. 3 is a detail.

Aisa central shaft,which is preferably of gaspipe or tubular wrought-iron. In reels of the larger sizes said pipe is provided with gudgeons A, turned to fit the interior of the tubular shaft and secured therein by bolts a, the spindle or hearing portions being turned to any desired size.

B B B are cast-iron hubs, secured in proper position on the shaft A by bolts or otherwise. The reel-arms b are of wrought-iron, upset or roughened at their inner ends and cast into the hub B.

O O are wooden ribs of the reel, attached to the ends of the arms Z2 by having holes bored therein at proper points to admit said ends, and held in place by pins 0. They are also supported by flanges b, welded or otherwise secured to the arms I; at equal distances from the center of the shaft. B, with their arms b, will be sufficient to suitably support the ribs 0, and in the shorter reels three will sufiicc.

To the outer ends'of the arms b, on the second hub from each end of the reel, are connected the brace-rods D. This is usually done by providing said brace-rods with a hook or eye, d, as shown in Fig. 3, which sets over the arm between the rib and the flange b, said flange being set far enough inward to admit the braces without deflecting the ribs 0 from a straight line. For the attachment of said brace-rods D at their opposite ends, a disk, E, is provided exterior to each of the end hubs of the reel and fitted to slide freely on the shaft A. Oblique holes are drilled through this disk near its margin, through which the brace-rods D pass, and outer threaded nuts, (1, are applied to the ends of the rods exterior to the disk, said disk being faced off or cast in suitable form to squarely seat these nuts.

Between the disk E and the adjacent fixed hub B is inserted a rubber disk, F, and, if desired, rubber washers f may be applied to the bracerods between the disk E and the nuts d. By tightening up the nuts on the brace-rods thus connected and arranged at both ends of the reel, said reel may be perfectly trussed, so as to keep its shape. and to run true, and by the yielding elastic action of the disk F expansion and contraction of the reel-frame or of the rods are permitted without disturbing the symmetry or accurate poise of the reel and withoutdanger of breaking said rods or the arms with which they are connected.

In order to give a better trussing effect to the brace-rods D, I prefer to extend them past the shaft A, or, in other words, to connect them with the disk E on the side of the shaft A opposite that at which they are connected with the arms b, as clearly shown in Fig. 1 of the drawings. This makes the reel still more Ordinarily four hubs,

rigid without increasing the strain upon the rods, and, though the movement of the disk E on the shaft A when said rods expand or contract is increased by this construction, the elastic disk F allows such movement and entirely avoids peril of breaking. The rods D in this case are suitably bent to pass the shaft A. Other bracing than that shown-as, for example, between the inner hubs and arms B b-is found. to be unnecessary in connection with the construction described.

In the case of long reels the use of gas-pipe for thecentral shaft is desirable as giving lightness with strength, the added gud-geons being readily fitted to give axial accuracy, and, of course, allowing the bearing parts to be reduced to any size.

In practice the hubs B and disks E may be relatively much smaller than shown in the drawings.

Several features of construction described are applicable to Wooden reel-frames; but iron ones are so far preferable when made practicable in respect to the matters stated that there will be little occasion to. apply said in] provements to wooden frames.-

In the case of a reel having three or five hubs all the brace-rods may be connected with the elastic substance, substantially as described,

and for the purpose set forth.

2. In a bolting-reel, the combination,with the frame-arms and outer hub, 13, of the disk E, the interposed rubber disk F, and the diagonal braces D, arranged and connected substantially as described.

3. In a bolting-reel, the combination, with the frame'arms and the yieldingly-supported disk E, of the brace-rods D, arranged to pass the central shaft between their points of attachment, substantially as described.

L In testimony that I claim the foregoing as my invention I aftix my signature in presence of two witnesses.
