CLEVELAND, OHIO.

CROZING IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 409,235, dated August 20, 1889.

Application filed August 1, 1888.

To all whom, it may concern:

Be it known that I, LEMON M. REED, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Or zing-Hachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in crozing-maehines in which the staves during their passage through the machine are bent to correspond with the bilge of the barrel, keg, or vessel for which they are intended, and while so bent are crozed, cut to lengths, and afterward discharged from the machine, the operations of the machine being entirely automatic.

In the accompanying drawings, Figure l is a side elevation. Fig. 2 is a plan. Fig. 3 is an enlarged side elevation in section. Figs. 4 and 5 are end views enlarged and in detail.

A represents the supporting-frame, having suitable boxes, in which are journaled, re spectively, the large shaft B, the spindles O C, and counter-shaft D. Shaft B is provided with driving-pulley B, mounted loosely on the shaft, with pinion B integral or rigidly secured to the hub of the driving-pulley, the pinion consequently revolving loose on shaft B. This pinion engages a larger gear (Z of shaft D, and on the same shaft is mounted pinion d, the latter engaging a larger gear Bf, the latter gear being mounted on and keyed fast to shaft B for rotating the latter. By such train of gearing the faster speed, such as would ordinarily be transmitted from a lined shaft to pulley B, is reduced to a slow speed suitable for shaft B. Spindles O 0, carryingthe cutter-heads, are run ata high speed, and are therefore driven direct by belts applied to pulleys C C. On shaft B is mounted a sectional former composed of sections Z) and b I), such former having the general appearance of a barrel or cask. The middle section Z) is keyed fast to the shaft, sections 1') b bein g adjustable lengthwise of the shaft according as the staves are to be bent more or less to correspond with the greater or less bilge of the barrel or keg for which such staves are erial No. 281,675. (No model.)

intended. The sections I) are keyed to the shaft, so that they rotate with same, but can be moved longitudinally thereon by loosening screws o which latter are mounted in the hubs of the sections and bear against the shaft. It will be observed that section b has a crowning face and that sections 1) have beveled and slightly-rounded faces placed in reversed order.

By contracting the formerthat is, by moving sections Z) 1) toward each other-the staves when pressed upon the periphery of the former are bent more, and by expanding the former the staves are bent less.

The mechanism for bending the staves to fit the former is as follows: Presser-bars E, having curved and prefe ably circular spaces of somewhat greater radius than the section Z), are secured to the frame-work of the machine. These presserbars are located, as shown, near the end of the former but outside the lines thereof. The presser-bars being eccentric with the aXis of the former, the upper end (2 of the presser-bars being far enough removed from the former to admit a straight stave between the former and presser-bars. At points 6' the presser-bars approach to near the axis of the former as to bend the staves inward onto sections 1), thus making the staves fit the former, and consequently shaping the staves to conform to the shape the staves will assume when placed in the keg or barrel for which they are intended. While the staves are thus bent on the former, the cutter-heads c e do their work on the successive staves as they pass,beveling the ends of the staves shown at f and cutting the crozings, as shown at f also, saws c 0, connected with the respective cutter-heads, cut the staves to lengths at the same operation. Beyond the cutter heads bars E recede from the former, so that the staves gradually unbend and at length fall by gravity upon apron K, and are carried from under the machine on the apron. The staves F are piled against the standards G, G, and H, the lower staves resting on the revolving former below. Sections 1) of the former are provided with projecting members-for instance, with series of blocks I, secured to the rims of these sections by means each of a single pivotal pin or bolt i. The blocks are arranged in pairs 011 planes parallel with the axis of the former, and the successive pairs of blocks engage the successive staves of the pile, carrying such staves under barsG with the result aforesaid.

It will be observed that the operations of the machine are entirely automatic and that the staves are crozed while they are bent to conform with the bilge of the barrel or keg for which they are intended, and that while they are so bent they are cut to lengths and afterward discharged in a completed condition from the machine. It will also be observed that the cutter-heads operate directly opposite, or approximately opposite, the presser-bars, and consequently the staves in passing are not only crozed and beveled and out to lengths, but are also dressed to thickness Where such crozing and bevelin g occur.

What I claim is-- 1. In a stave-crozing machine, the combination, with a former made up of center and end sections, the latter having projections thereon for engaging the staves and adjustably secured on the shaft, whereby they can be moved toward and away from the central section, curved presser-bars located at one side of the vertical center of the former, and standards for supporting a series of staves, the said standards being located adjacent to and in front of the upper ends of the presserbars, of cutter-heads for crozing and dressing the ends of the staves and cutting the latter into lengths, substantially as set forth.

2. The combination, with a sectional former and cutter-heads for cutting and dressing the ends of the staves, of the presser-bars located wholly to one side of the vertical center of the former, and standards also located on the same side of the vertical center of the former and adapted to support a number of staves, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this 8th day of June, 1888.

LEMON M. REED.
