DOFFER MECHANISM.
SPECIFICATION forming part of Letters Patent No. 543,126, dated July 23, 1895. Application filed November 3, 1394. Serial No. 527,799- (No modelo To all whom it may concern.-
Be it known that we, EDWARD WV. BUELL and SIVERT MOE, citizens of the United States,
residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Doffer Mechanism, of which the following is aspecification, reference being bad therein to the accompanying drawings.
This invention relates to certain new and useful improvements in ironingmachines, and more particularly to doffer mechanism therefor, having for its objects, among others, to provide a blade and mechanism whereby the goods are more positively removed from the clothed roll.
The doffer-blade is arranged with its acting edge located at a point more or less below the center of the drum-axis, it being well known that the goods begin to fall away from or leave the clothed roll just ata point below its axial center. To facilitate the goods in their movement away from the clothed roll we employ means, as an idler-roll, which is arranged with its periphery adapted to bear against the clothed roll at a point between the acting edge of the doffer-blade and the center of the drum-axis. This will tend to concave the goods, and 'the lower edge thereof will thus be thrown farther way from the clothed roll and turned outward to better fall upon the doffer-blade and in position to be conducted thereby between the other roll and its heated ironing device. In one of its forms the doffer-blade is made in sections and supported upon the heated ironing device of the lower roll. The idler-roll may be dispensed with under some circumstances. The dofferblade will serve with other devices for concaving the goods between the blade and the center of the drum-axis.
Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is an enlarged view, partly in secder.
tion and partly in elevation, illustrating the application of ourinvention. Fig. 2 is an elevation with a portion broken away, looking in the direction of the arrow :1; in Fig. 1, of the doffer-blade. Fig. 3 is a top plan view of the doffer-blade.
Like letters'of reference indicate like parts throughout the several views.
v Referring now to the details of the drawings by letter, A designates a portion of the ironing cylinder or drum, which may be clothed in any suitablemanner, and'B is the lower roll, also of any well-known or approved form and adapted to be actuated in the usual way. 0 are the steam-pans or ironing devices, also of known construction and mode of operation.
The doffer-blade D is located ata point be low the center of the drum-axis, as shown in 'Fig. 1, so that its acting edge or portion or portions will contact with the roll or cylinder A at a point somewhat below said center line, the exact distance below such line beingdetermined by experience and dependent somewhat upon the diameter of the roll or cylin- It is well known that the goods being ironed begin to fall away from the drum vertically after they pass the center line, and the acting face of the dofifer-blade is arranged so as to' remove or disengage such articles as do not of themselves leave the drum or cylinder as soon as the drum passes the central line,
the doffer-blade being inclined toward the roll B, as shown in Fig. 1, to automatically guide the goods to the roll B, as illustrated in Fig. 1.
It is desirable that some means be employed for aiding the goods in their separation from the cylinder. For this purpose we have herein shown an idler-roller E, suitably journaled and arranged, so that its periphery will be in contact with that of the cylinderA at a point between the acting face of the dofier-blade and the point where the goods naturally would leave the face of the cylinder-that is, at the center of the drum-axis. designed to press upon the goods and the covering of the roll or cylinder A sufficiently to concave the same at this point, so that when the goods emerge therefrom their lower edge will be curved or turned outward from the This idler is 9 5 periphery of the cylinder A and in their further movement will be deposited upon the dofier-blade, as will be readily understood.
The dofEer-blade is designed to be mounted in the machine in any suitable manner as, for instance, by means of bolts to the frame,
as indicated by dotted lines in Fig. 3-and its upper and lower edges are slightly tapered and may be somewhat curved in opposite directions, as shown in Fig. 1, for the purpose of better conducting the goods away from the cylinder A and to the roll B. The blade is formed in sections in any suitable manner as, for instance, as indicated by dotted lines in Fig. 3and this blade is what may be termed a skeleton blade, inasmuch as it comprises the upper face, from which depend the vertical ribs 01 toward the rear or that portion designed to be nearest the cylinder A and the vertical ribs (1 upon a diiferent plane, as seen in Figs. 1, 2, and 3, and the transverse ribs 01 the ribs d being designed to rest Within a channel or groove 11 in the heated ironing device 0, as shown in Figs. 1 and 2, although the said ironing device may be otherwise formed. The upper edge of the blade is formed at intervals with the lips (1 as seen best in Fig. 3, which are designed to bear against the clothing of the roll or cylinder to insure the positive removal of any goods that might perchance adhere. to the said cylinder.
Owing to the length and enormous weight of the cylinders or drums employed in this class of machinery it is most desirable to have the doiter-blade of such rigidity that it will not buckle or bend, but will maintain its parallelism with relation to the periphery of the drum at all times. The ribs herein described are provided to insure this end.
Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.
The idler-roll E may be supported in position in any suitable manner. It may be suspended so as to bear against the drum from its own weight, or any suitable device can be arranged to press it against the drum with any desired pressure.
l/Vhat is claimed as new is- 1. The combination of a revoluble cylinder, a dofter blade and means interposed between the blade and the horizontal axial line of the cylinder to turn the goods from the cylinder between the dolfer and the last ironing device, substantially as described.
2. The combination of a revolnblecylinder, a dofter blade, and an idler roll mounted to act against the cylinder above the dofter blade, as set forth.
3. The combination with a revoluble cylinder, of a doft'er blade, and an idler roll ar' ranged to act against the cylinder between the said blade and the horizontal axial line of the cylinder, as set forth.
In testimony whereof We affix our signatures in presence of two witnesses.
