DIVIDING AND BANDIE'G MACHINE.

Specification of Letters Patent.

Patented Aug. 23, 1910.

Application filed April 8, 1910. Serial No. 554,245.

To all whom 'it may concern:

Be it known that I, Auous'r G. BAUER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Dividing and Banding Machines, of which the following is a specification.

My invention relates to the. improvement of dividing and banding machines of that class which are particularly adapted for use in facilitating the decoration of china plates or other disks, and the objects of my invention are to provide a device of this class wherein is combined improved means for dividing the surface of a plate or disk into uniform spaces through the production of radial lines, cords, circles and other divisional indications thereon.

A further object of my invention consists in providing improved means for supporting a plate against undesirable rotation or movement and for centering the plate upon the supporting drum.

1 These objects I accomplish in the manner illustrated in the accompanying drawing, in which- Figure 1 is a plan view of my device, Fig.'

2 is a side elevation thereof, Fig. 3 1s a sectional view on line 33 of Fig. 1, and, Fig. 4 is a detail section on line 44 of Fig. 1.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention, I employ a supporting frame which consists in a horizontal member 1 from the forward end portion of which rises a tubular standard 2 and from the base of which extends radially a desirable number of supporting legs 3. About the tubular standard 2 is provided a horizontally disposed drum 4, the top member of which is formed on its underside with a central downwardly extending bearing pin 5, this pin extending within the central socket or opening of the tubular member 2. The weight of the drum, however, is supported by bearing balls 7 which are arranged in a circular cage 8 between the enlarged head of the pin and the upper end of the tubular member 2, these balls having their upper sides in contact with the underside of said pin head enlargement and having their lower sides in contact with the upper end of the tubular standard 2.

In the construction of the drum 4, I provide the otherwise flat upper face thereof, with a plurality of circular grooves 9 which are struck from the center of the drum head. Through the upper side of the drum, are formed radial lines of vertical pin holes or sockets 10, these sockets being arranged to intersect the grooves 9.

In the outer end of one of the legs or base frame arms 3, is supported the lower end of an upright post or bar 11, the latter having formed therethrough a vertical line of equidistant pin openings 12 either one of which is adapted to receive the stem of a suitable pin 13. Through the vertical cylindrical wall of the drum 4 are formed straight, curved and inclined lines of pin openings or sockets 14, which openings are in horizontal alinement with the pin openings 12 of the post 11. The openings 14 are so arranged with reference to each other, that the distances between all of those openings which are of equal height from the bottom of the drum, represent equal divisions of the circumference of the drum. For example, the space or distance between any two of the highest openings 14 on the drum, is equal to one-third of the circumference of the drum, while the next lower horizontal row of openings 14, divide the circumference into fourths and the lower openings near the bottom of the drum, divide the circumference of said drum into sixteenths.

Upon the outer end of the frame member 1, is pivoted the vertical pin extension 15, which depends from one end of a horizontal bar 15 in the outer or remaining end of which is pivoted the vertical pin termination 16 of an upright standard 17 This standard is adapted to be rotated to the desired position and held in such position through the medium of a set screw 18, which passes through a threaded opening in the outer end of the bar 15, while a similar set screw 19 in a like manner, passes through the outer end portion of the frame member 1 and engages the pin 15. The standard 17 has slidably connected therewith, the outer hookshaped end of a horizontal arm or bar 20, which is adapted, as shown in the drawing, to extend over a portion of the upper side of the drum 4. This arm is held at its desired height on the standard 17 by a set screw 21. Adjacent to the periphery or on the outer marginal portion of the horizontal drum top, I provide upwardly projecting I side or face of the arm three eqnal spaces.

- 5 post 11, the pin is pins 22, these pins being arranged diametrically opposite each other and being connected by rubber bands 23, which are under tension, said bands crossing each other at the center of the drum top.

In utilizing my improved device for dividing a plate into desirable divisions or spaces, the plate is supported centrally upon the drum and upon the crossed rubber bands 23, and in order to insure the retention of the plate in its central position, retaining pins, are inserted in the corresponding pin holes 10, these pins contacting with the edge of the plate and insuring its central support on the drum. Owing tothe fact that the plate rests upon the rubber bands, any tendency of the plate to rotate upon the drum, 1s obviated.

It will be observed that for the production of radial lines on the plate, the arm 20 and itsgsupports are so set as to cause said arm to extend radially over the upper side of the drum and beyond the center thereof, one being substantially inalinement with the drum center and plate center. Wewill assume that it is desired to produce upon the plate, radial lines whereby the face of the plate, will be divided into In order to attain such a division, the pin 13 which is supported in the upper opening 12 of the post 11, is drawn out of engagement with an upper drum opening sufliciently to permit a rotation of the drum. 7 When thedrum has been manually moved-or-rotated until the pin 13 is opposite the next succeeding opening 14: which is of corresponding height on the drum with that occupied by the pin in the pressed into said opening 14; to temporarily lock the drum against further movement. third of a completev rotation of the drum, has been attained and'at the beginning and ending of this operation, radial lines are center of the plate to the drawnfrom the outer margin thereof by means of a pencil which is held, upright and in contact With onefface of the guide arm 20. By thus successively withdrawingthe pin 13. and inserting the same in the upper openings, as the drum is. revolved and: utilizing the arm 20 as astraight edge, it will be understood that the; upper face of the plate will be divided by the-pencil lines intothree equal divisions. Byutilizing} the next lower set of pin holes 1'4: for the reception of the pin 13, it is obvious that thesurfaceof the plate may be dividedinto fourths and in a. like manner other-divisions of theplate may be made by the insertion of theopenings.

Itis-obviousthat the ingcircles on thepin 13 into said lower operation of producplate or of impartinga j marginalba-nd, thereto, may be accomplished by holding a brush vertically against the shown and described ,cumference of said from the frame adjacent to the periphery of the body and having openings therein in horizontal alinement with the pin holes in said body, and an arm connected with said standar 5 and extending above said rotatable body- Bythis operation, one- 5 the combination with r circular rotatable body mounted thereon and provided with lines holes, there being circles formed on the upper face of said rotatable body, and means arm 20 at the desired point. It will also be understood that by swinging the arm 20' and its standard 17, the arm may be made to extendover portions of the drum at different angles, thus admitting of the production of lines in different directions on the plate and aiding in the production of certain desirable designs thereon. This movement of the arm 20 for the purpose of producing cord lines on the plate and other design lines, is facilitated by the employment of the bar 15 which may be swung to such position as to admit of a desirable intersection of the arm 20 with the circle described by the drum.

From the foregoing description, it will be seen that simple and eflicient means areherein provided for accomplishing the obj ects of the invention but while the elements are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but

includes within its purview such changes as may be made within the scope of the appended claims.
