STENCILING-MACHINE.
oos-m5.
Patented May 5, 1914.
Original application filed April 6, 1909, Serial No. 488,226. Divided and this application filed March 24, 1911. Serial No. 616,609.
T 0 all whom it may concern:
Be it known that we, CHARLES GIBBS, re siding in the borough of Bronx, city, county, and State of New York, and JACOB SoKoLov, residing in theborough of Brooklyn, city of New Yorr, county of Kings, and State of New York, both citizens of the United States, have invented certain new and useful Improvements in Stenciling-Machines, of which the following is a specification.
This invent-ion relates to stenciling machines and this application is a division of application No. 488,226, filed April 6, 1909.
Sheets are usually fed between a stencil cylinder and a pressure roll. The stencil cylinder may be turned by a handle or mechanically. The cylinder requires cleaning of ink after having been out of use for a considerable length of time, or when an inn of different color is to be used. It is also sometimes desired to substitute a cylinder having adifterent stencil from that in the machine.
The principal object of this invention is to enable the stencil cylinders to be readily removed and replaced, whether powerdriven or manually rotatable, and without disturbing other parts of the machine. Ac cordingly, the stud which supports the hub at one end of the stencil cylinder is mounted in a bearing, the cap of which releasably holds the stud in place. One of a train of driving gears is preferably loosely mounted on the stud, said gear having a sleeve journaled in the frame of the machine, and a nut threaded on the outer end of the stud engages the sleeve to clamp the gear and hub between itself and a head on the stud, to enable the gearing to turn the cylinder.
Other objects and advantages will herein after appear.
In the accompanying drawings, Figure 1 is a side view, partly in section, of the invention applied to an Underwood revolving duplicator. Fig. 2 is an end view showing the cylinder locked to the frame. Fig. 3 shows the cylinder released.
The stencil cylinder 1 is of the usual type, and may be rotated either by a handle 2, Fig. 1, or a power shaft 3, by means of a motor 4, the latter being connected by a spring ratchet 5 to a ratchet collar 6 on the power shaft, to permit the stencil cyhnder then advance the sheets through the machine.
One end of the cylinder has a rim 11 running between trundles 103 mounted in the frame of the machine, and to enable the cylinder to be fed by hand, one end of said cylinder has a hub 94 in which is loosely inserted a stud 95 having a head 95 The outer threaded end of the stud projects through a journal boX 100 formed in a standard 20 of the frame and carries a nut 90, whereby the cylinder is secured to the stud. The gear 9 on the stud has a sleeve 99 seated in bearing 100 to form a journal for the cylinder, and by screwing the nut on the stud the outer end of said sleeve is engaged by the nut 96 to press the hub 98 of the gear against the hub 94 of the stencil cylinder which in turn is pressed against the head 95 of the stud, to clamp the gear and cylinder to the stud.
A cap 101 pivoted at 102 and forming part of the journal box may be swung up to release the sleeve 99 and stud 95 thus leaving the sleeve resting on the pillow of the journal to enable the stencil cylinder and gear to be removed and replaced. The gear 9 is readily disconnected from and meshed with the gear 8. A pin 104 passing through aperforation in the journal box 100 and through a registering perforation 105 in a tongue 106 on the cap, fitting in a recess 107 in the journal box, locks the cap in closed position to hold the cylinder against displacement. The nut 96 and gear 9 on 0pposite sides of the journal box prevent endwise play of the cylinder. Depression of the finger piece 109 on a lever 108 pivoted at 111, against the tension of a returning spring 110 withdraws the pin or bolt 104 to enable the cap to be lifted, when it is desired to remove the stencil cylinder. A key 98 on stud 95 engages a groove 9 to rotate the stud from the gear.
Having thus described our invention, we claim:
1. In a stenciling machine, the combination with a frame having a bearing, of a sleeve journaled in the bearing, a studprojecting through the bearing and sleeve, a stencil cylinder, the hub of which is mounted on the stud on one side of the bearing, a nut threaded on the stud on the opposite side of said bearing taking the thrust of said sleeve, an abutment on the stud against which the cylinder hub is pressed by said sleeve, and a gear on said sleeve between said hub and bearing.
2. Ina stenciling machine, the combination with a stencil cylinder having a hub, of a stud passing loosely through the hub, a gear on the stud having a reduced sleeve, a bearing in which the sleeve is journaled, the stud projecting through the sleeve and bearing, a nut on the stud to engage the sleeve and press the hub of the gear against the cylinder hub, and an abutment on the stud engaged by said cylinder hub; said nut and said gear holding said sleeve against endwise play in said bearing.
3. in a steneiling machine, the combination with a stencil cylinder having a hub and an axle on which the hub is secured, ot' a gear on the axle, a journal box in which the axle is mounted, said journal box including a cap pivoted to swing ofi from the axle to release the cylinder, and a driving gear on the frame releasably engaged by the gear on the axle.
t. In a stenciling machine, the combina tion with a stencil cylinder having a hub and an axle on which the hub is secured, of a gear on the axle, the hub of which contacts with the cylinder hub, a journal box in which the axle is mounted, a nut threaded on the axle, to press the gear against the cylinder hub, an abutment on the axle engaged by the cylinder hub, said journal box including a cap pivoted to swing off of the axle to release the latter and the cylinder, and a driving gear on the frame releasably engaged by the gear on the axle.
5. In a stenciling machine, the combination with a stencil cylinder having a hub, a stud on which the hub is loosely mounted, and a nut threaded on said stud, of a gear axially movable on said stud between the cylinder hub and the nut, a sleeve between the gear and nut to act as a journal for said cylinder, a journal box in which said jour nal is detachably mounted, and a driving gear on the frame releasably engaged by the gear on the stud.
6. In a stenciling machine, a stencil cylinder loosely mounted, a stud having an abutment against which the hub of said cyl inder is pressed, a nut threaded on the stud to connect the cylinder to the stud, a train of gears for turning the cylinder comprising a gear on the stud, said stud gear being axially slidable on said stud between the nut and the cylinder hub against which latter it is pressed by the nut, and a sleeve on the stud journaled in a bearing, said bearing including a releasable cap so that when the cap is lifted, the cylinder,'staul, gear, sleeve and nut may be removed from and replaced in the machine without disturbing other parts thereof.
