SPECIFICATION forming part of Letters Patent N 0. 679,983, dated August 6, 1901.

Application filed November 28, 1900. Serial No. 37,997. (No model.)

T @ZZ whom, it' muy concern:

Be it known that I, CHARLES E. ONEIL, of Toledo, county of Lucas, and State of Ohio, have invented certain new and useful Improv-ements in Decorating-Machines; and I do hereby declare that the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which it appertains to make and use the ro same, reference being had to the accompanymachines, and is designed to be employed in ing drawings, and to the'igures of reference marked thereon,which form part of this speciaication.

My invention has reference to decoratingthe production of what is variously known as relief-Work,7 gunwork, dac.

The object of my invention is to provide a device for the production of relief-Work in a no more perfect and uniform manner and with 3o inder having thereon a nozzle and containing a piston, to which is attached a rod having on the end thereofa handle, by which the device is operated. In this device the cylinder is held in the left hand, while the right oper- `ates the piston and forces the plastic material out of the cylinder through the nozzle. All of these devices have proven unsatisfactoryintheiroperation. In'usingthelast-mentioned device (the gun) the great objection 4o has been that the right hand is employed to invention overcomes these objections and pro- 5o same during operation.

operate the piston, while the left hand,which holds the cylinder, traces the design. This has naturally resulted inimperfect Work, due to the imperfect control of the left hand. My

vides certain novel features of construction hereinafter shown, described, and'claimed.

In thedrawings, Figure 1 is a View of my machine, showing the manner of holding the Fig. 2 is a perspective view of the frame of my machine, the working parts being removed therefrom. The

clamp for holding the cylinder in position is shown released. Fig. 3 is a View of the cylinder removed from the machine,.showing a section cut therefrom to disclose the interior. Figs. 4 and 5, respectively, are sectional views showing the operation of the mechanism of the machine.

Referring to the drawings, 1 is the frame of the machine,having the parallel sections 2 and 3 connected by a semicircular section 4. Section 3 is formed with a hinge connection on the end thereof at 5 for the attachment of a clamp 6, having a clasp 7 adapted to engage a hook S on the end of section 2. Clamp 6 has a tube 9 passing centrally therethrough,

on the end of which is secured the ejectingtube 10. Tube 9 is preferably tapered, as

shown at 11, to enter an opening 12 in cylin-l der 13. Between the sections 2 and 3 is secured the annular member 14, having the i beveled edge 15, into which the beveled end..i Y

16 of cylinder 13 is designed to enter. The annular member 14 has the same inside diameter as the cylinder 13, so that when the cylinder -is placed in the frame 1 and securely clamped down, as shown in Fig. 1, member 14 is practically an extension of cylinder13. Framel is divided at 17 into two sectionslS and 19, occupying parallel planes, between which are secured the Working parts of the machine.

2O is a rack-bar, to the end of which is secured in any suitable manner a piston 21, which snugly ftst-he inside of cylinder 13, and consequently member 14. Meshing with the rack-bar 2O is the pinion 22, to which motion is imparted by a lever 23, fulcrumed at 24 and having on the end thereof a pawl 25, hinged thereto at 26 and held normally iu contact with pinion 22 by a spring 27.

28 is an extension of the pawl 25, to which t root ` I provide the pawl 33.

in the hand, with the thumb resting upon the lever 23, Fig. 1. The position of the mechanism at the beginning of the operation isshown in Fig 4. The lever 23 is then depressed, which will cause the pinion 22 to advance in the direction of the arrow because of engagement with the pawl 25. The movement thereof will, however, be limited by the arc of rotation of the short end of lever 23. As the pinion 22 advances, the rack-bar 20, meshing therewith, and consequently piston 21 on the .end of the rack-bar, will advance in cylinder 13 and force the composition contained in the cylinder through the nozzle 10. The lever 23 is then released by raising the thumb and will again assume the position shown in Fig. 4,because of spring 30,-connected therewith. As the lever 23 is depressed at successive intervals, the cylinder 13 is entirely emptied of its contents. To prevent back motion of the rack-bar 2O and pinion 22, because of the reaction of thematerial inthe cylinder, After the cylinder is empty the machine is held upside down in the left hand, with the little finger resting upon the extension 2S of pawl 25 and the other fingers depressing lever 23. Pawl 25 will then be in the position shown in dotted lines a and pawl 33 in the position b, also shown in dotted lines, falling to this position through the force of gravity, Fig. 5. Since the pawls have now been 4detached from the pinion, the rack and piston are easily drawn back to the position with which the operation commenced. Clamp 6 is then released and the empty cylinder removed from the machine and replaced by another cylinder which has been filled with the composition. By

Vemploying two or more cylinders no time is lost in lling the machine. While the operator is working the machine his helper is cleaning the empty cylinders and filling the same with the composition. y

From the foregoing descriptionthe improved operation, construction, and advantages Will be apparent.

Having described my invention, what I 55 claim, and desire to secure by Lei ters Patent, 1S 1. In a. decorating-machine, the combination with the frame, of cylinder, removable therefrom, the clamp for holding the cylinder inposition, the piston movable in the cylinder, and means foractuating the piston, substantially as shown and for the purpose specified.

, 2. Ina decorating-machine the removable cylinder secured' in the frame and held in position by a clamp, an opening in the end of the cylinder to register with an ejectinga tube integral with the clamp, the piston and rack movable in the cylinder, the pinion meshing with the rack, the lever having the pawl on the end thereof to actuatethe pinion, rack, and piston, the spring to return said lever to its normally raised position, the pawl in engagement with the aforesaid pinion to prevent back motion of the piston, substantially as described and for the purpose specied.

3. In combination the frame, the remov able cylinder, the nozzle registering with an opening in the end of the cylinder, the vrack and piston movable in said cylinder,

the pinion meshing with the rack, the lever with the pawl on the end thereof to normally engagethe pinion, and extension on the pawl, for disengagement of the pinion, a spring having one end thereof attached to the frame and the other end attached to the aforesaid lever to raise the same when released, and a pawl normally in engagement with the aforesaid pinion, to prevent backmovement of the piston, and adapted to Afall by gravity when the machine is inverted and thereby disengage the pinion substantially as 'described and for the purpose specified.

' In testimony that I claim the foregoingas my own I affix my signature in presence of two witnesses.

CHARLES E. ONEIL.
