Description

@atten galitaire atrut- @EfiraA SELDEN A. BAILEY, 0F WOONSOCKET, RHODE ISLAND, ASSGNOR TQ BAILEY WASHING AND WRINGING-MACHINE COMPANY, OF SAME PLAGE.
Laim Patent No. 77,346, rated April 28,1868.
IMPROVED WRINGING-MAGHINE.
TO ALL WHOM'IT. MAY CONCERN:
i' Be it known that I, SLDE A. BAILEY, of Woonsocket, in thel county of Providence, and in the State of Rhode Island, .have invented -ccrtain new and useful Improvements in Wringing-h-Iachincsg and do,l hereby declarethat the following' isa full, 'clear, and exactdeseription th'crcof, reference bcing had to 'the accompany ing drawings, forming part of this specication, and in which y Figure 1 `represents an end view cfa wringing-machine 'with my improvemcntsattaohed.
Figure 2, a side view ofthe same. d
Figure 3, a longitudinal section of a portion of one of the rolls, and
Figure 4 a transverse section of the same. Y
The nature of m'y invention consists in- -v First, forming the teeth 'of the driving-gears with enlarged extremities', the sections of. which are nearly circular, in form, with shanksdiminishing toward their hub, as shown, for the purpose of enablingl them to adapt -themselves toQthe variations of distancebetweenjthe centre of the rolls caused by the different articles that pass through them,` 'and providing them -with ilanges, which4 serve;to preventA them from engaging too. deeply,rand also to prevent end motien and wear of the rolls.-
Secondly, in providing an easyadjustment for the rods which-stiften and support the rubber covering ol" the rolls, so as., to give the same suieient firmness and elasticity, without liability of injury to the rods.
In the accompanying drawings,-A A represent the rollsrofthe wringingmachine. The rolls are geared at each cud by the gears a 11,6 b1, and are driven by'lthe prank, B, upon the shaft of thcroll A. The roll A is susceptible of vertical motion to admit articles of different thicknesses, and is pressed up against rzoll A by the springs C. lThe enlarged and nearly circular extremities ofthe teeth, with shanks diminishing toward the hub, enable them to work when the rolls are forced apart, and the bluntness of their points prevents the latter 'from wearing or breaking when so working. The teeth are provided with flanges aib?, a3 b3, which, by coming in contact with the hubs of the opposing gears, prevent theteeth from engaging each other toodeeply, and the wear thereby occasioned, and also prevent longitudinal motion and wear of the rolls.
The rollsv are constructed in the followingmanner: Thin sheets of calendred rubber are wound upon a central shaft turned down at its ends to form suitable journals.' Stiifening-rods, d, figs'. 3 and 4,`ar'e.arranged `around this shaft: lThe spaces between the rods arefthen filled with similar rubber, and suitable caps secured a't theends. ofthe rods. By exposure to steam of high temperature, the nubber'is welded or united into a solid mass, and the rods and central shaft may-be withdrawn from the mould. 'Before beih-gvre'turned, they receive a coat oi' Cepal-varnish, and are wound round with twine, which increases theirdiameters, and causcsthem to be a tight t in the rubber, preventing any movement, and consequentv friction. The stiieningerods are held in position by the collars D, which may be made either' in one or two pieces. When in two pieces, as shown, theinner ones have holesdrilled through them, in which the rods tit easily, with some little end-play allowed, so as to allow 'them to spring slightly without bending or breaking. The outer portionsof the collars serve 'as capsto cover the holes and prevent the rodsfrom Working through. The collars can be secured upon the shafts by steady-pins, keys, orin any suitable manner.
The machine is put in 'motion by the crank'on the shaft of roll A', which, by thegcars on its ends, gives motion tothe roll A. ,The articles to bewrung'arc passed between'th'e rolls, and when of suicientthickness to force the latter apart,'the elongated elliptical' form of the teeth enables the latter to continue in workingv gear with each other,',whle the biuntuess of their points prevents them from being worn or broken, .as they would be if sharp. The teeth-anges a 62,413 b3 willstrike upon the 'hubs of the gears opposite to them, should.
the upper roll be returned too far by th'e springs C C, and thus prevent the teeth from engaging each other toe deeply, while the arrangement of the anges, as will be seen from fig. 2, obviates end motion of the rolls, and consequent wear. The collars D hold the rods d securely in thcrolls, with such an adjustment as to allow themto spring slightly, when reqircd, forinng a. roll at once firm and elastic. When 'the collars are made in one instead of two pieces, the, holes are drilled only part way through the solid metal at the bo'ttom of each,v serving instead ef the separate cap first described.
What I claim, and desire to secure by Lett-ers Patent, s i 1. 4Flanged teeth, with, their extremities enlarged, andnearly eireular in ferm, and with Shanks diminishi ing toward the hub,V substantially as shown and described.' y
` 2. -A gear having n. separate flange on eaeh'tooth,.as and for the p urpose set forth.
3. `The collars D, constructed to admit and retain the stifeningdod's of-tlre rolls, substantially 'as described. 4. The stieningfrods d, so fitted and held in the cellars as te allow end-play,- eubstantially as land for the purpose set forth. Y
