WHEEL LACING AND TRUING CHUCK.
SPECIFICATION forming part of Letters Patent No, 597,613, dated January 18, 1898. Applioatltn filed Tune 3,1891. Serial No. 639.261. on model.)
To ctZZ whom it may concern.-
Be it known that I, HARRY T. KINGSBURY, a citizen of the United States, residing at Keene, in the county of Cheshire, State of New Hampshire, have invented certain new and useful Improvements in Wheel Lacing and Truing Chucks, of which the following is a description, reference being had to the ac I companying drawings and to the letters of reference marked thereon.
The invention relates to a lacing and truing chuck for bicycle-wheels.
The object of the invention is .to provide a simple and effective chuck for clamping the rim in true relation to the wheel-hub while the spokes are being laced and secured to the hub and rim.
The invention will be first described, and then specifically pointed out in the claims.
Referring to the drawings forming part hereof, Figure l is a perspective of the improved lacing and truing chuck with the arbor-brace removed. Fig. 2 is a similar view with a rim and hub in position for lacing and securing the spokes prior to the application of the arbor-brace. Fig. 3 is a similar view with said brace in position, and Fig. 4: is a perspective of the arbor-brace.
A represents a standard having a suitable supporting-base, and B is the horizontal bed.
of the chuck, mounted on the upper end of the standard.
The bed 13 is formed of a center piece B,
from which extenda series of radial arms B on the outer ends of which turns the horizontal concentric clamp-operating ring 0, the connection being effected by providing the outer ends of the arms 13 with peripherallygrooved horizontal wheels 6, which receive a peripheral flange 0 on the inner side of the ring G. The center piece B has a verticallythreaded hub-supporting arbor D, provided with upper and lower adjustable centeringcones D D, adapted to be adjusted toward and from each other so as to clamp and center ,hubs of diiferent lengths. Concentric with the arbor D are formed circularly-arranged series of apertures h b h to receive the inner downwardly-bent pivot ends e of the rim-clamping arms E, the outer ends of the said arms being in sliding connection with and provided beyond ring 0 with concave jaws e to engage the inner convex edge of the wheel-rim. hen the arms E are in engagement with the outer series of apertures b, they are adapted to clamp a thirty-inch rim, while the next series 11 provide for a twenty-eight-inch rim and the outer aperture b for a twenty-siX-inch rim. As adj usted in the drawings, the arms will clamp a twenty-eight-inch rim. The arms E are pro vided with the slides e which are mounted to slide in the guides or brackets C on ring 0. One of the radial arms B is provided with a handle b, and the ring 0 is provided with a handle 0. The lower edge of the ring C is provided with ratchet-teeth c, which are engaged by a pawl Z2 carried by the handle I), so that when the handles 6 c are pressed together and the clamping-arms E thereby forced outwardly to clamp the wheel-rim the pawl will lock the parts in their adjusted position. lVhen the pawl is released and the handles forced apart, then the arms E will be drawn inwardly out of engagement with the rim. I11 order to support the rim in the path of the said arms E when the' arms are thus drawn inwardly, I provide said arms on their outer ends with supports 6 which project beyond the main parts of the jaws 6'. These supports e are, in fact, eX- tensions of the lower ends of the jaws e, and the rim when placed thereon will lie directly in the outward path of the said jaws c".
H is the arbor-brace to support the arbor D against lateral strain. This brace is in the form of an arched frame or spider having a central aperture to receive the upper end of the said arbor, on which it is held by a thumb-nut H, and the lower ends of the brace-arms h enter apertures h in the outer ends of the radial arms B The operation, briefly summarized, is as follows: The handles 6 o are forced apart, and hence the arms E will be moved inwardly. The rim is now placed on the supports e and the handles moved toward each other to force the clamping-jaws outwardly until their jaws receive the rim. The hub will then be placed on the arbor and properly centered and adjusted by the cones D D. The spokes will then be laced properly in place and their tighteningsnipplcs started, after which the arbor-brace will be secured in place. To get the best results, tighten four nipples and then pass to the other side and tighten four more, and so continue around the rim, snapping the spokes and depending on the sound to get a uniform tension. It is not necessary to strain the spokes very tight, but it is necessary to tighten them uniformly. After all of the spokes are thus tightened the wheel when removed will be found to be perfectly true.
Having thus described myinvention, what I claim, and desire to secure by Letters Pat-v ent, is-
1. The combination with the bed having a series of radial arms provided at their outer ends with grooved rollers, and a clamp-operating ring having a flanged inner side projecting into the roller-grooves, of a series of clamping-arms pivoted concentrically at their inner ends to said bed, extending across and in sliding connection with said ring and terminating at their outer ends in rim-engaging jaws, substantially as described.
2. The combination with the bed having concentric series of apertures, and a clampoperating ring mounted to turn on the bed, of a series of clamping-arms having lateral pivots at their inner ends to enter the apertures of any series, said arms crossing and in sliding connection with said ring for projec: tion and retraction thereby and terminating at their outer ends in jaws to engage the rim; substantially as described.
3. The combination with the table having a central hub-arbor provided with hub-adjusting devices or cones, and a ring turning on the bed concentric with said arbor, of clamping-arms pivoted at their inner ends concentric with the arbor and extending outwardly across and in sliding connection with the ring for retraction and projection thereby, the outer ends of the jaws being provided with rim-engaging jaws, substantially as described.
4. The combination with the bed, having a handle provided with a pawl, the central hub-arbor provided with hub-adjusting devices, a ring turning on the bed and having a rack engaged by said pawl and a handle on the ring of the clamping-arms pivoted to the bed, in sliding connection-with the bed and retracted and projected thereby when said handles are moved apart and toward each other respectively, the outer ends of the arms being provided with rim-engaging jaws, substantially as described.
5. The combination with the bed having a central hub-supporting arbor, a removable spider-like arbor-brace having a central aperture to receive the outer end of the arbor, the depending arms of the brace being adapted to engage sockets or apertures in the bed, and means for securing the brace to the arbor, of the rim-clamping arms and their operating means, substantially as described.
6. A lacing and truing chuck comprising a base, a standard, a bed on the upper end of the standard, a hub-supporting arbor, an arbor-brace, aring turning on the bed concentric with the arbor, means for operating and locking the ring, and the rim-clamping arms pivoted at their inner ends concentric with the arbor and extending outwardly across and in sliding connection with the ring, the outer ends of the arms being provided with jaws to engage the rim, substantially as described.
7. A lacing or truing chuck, comprising a support, or bed, a hub -arbor, a series of clamping-arms having jaws at their outer ends to engage a wheel-rim, said arms being adjustable longitudinally for different sizes of rim and means for projecting and retracting the arms, substantially as described.
8. The combination with the bed or plate having a hubarbor and a series of apertures concentric therewith, of a series of clampingarms having pivotal connection at their inner ends with said apertures and provided with rim-engaging jaws at their outer ends, the said apertured plate and the ring being capable of rotary movement relative to each other to project and retract the clampingarms, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
HARRY T. KINGSBURY.
