Patented Nov. 10, 1936 PATENT OFFICE MARKED RUBBER GOODS AND METHOD FOR PRODUCING THE SAME Walter L. Kauffman, 211, Erie, Pa., assignor to Lovell Manufacturing Company, Erie, la., a corporation of Pennsylvania Application July 11, 932, Serial No. 621,9l9 s Claims. (01.101-8) With many rubber articles it is desirable to mark the article, as for instance; with a trade .mark and the present invention is designed to form such a mark so as to give a pleasing appearance and be practically permanent. The invention also contemplates'a simple and eifective method of producing the mark and an apparatus by which it may be readily produced. The-invention further contemplates the application of the mark on wringer rolls. It is desirable to have some indication on wringer rolls by which the operator may *be readily apprised of the fact that the rolls are in motion and the direction of motion. Heretofore it has been suggested to form wringer rolls'of different qualities of rubber so as to contrast different portions of the roll for this purpose. In carrying out the present invention the roll is marked so as to give an indication of the direction of rotation and in carrying out this purpose the mark is preferably in the form of a symbol which may have the function of a trade mark. An apparatus is Fig. 2 a side elevation of an apparatus for marking the roll.
Fig. 3 a section on the line 3-3 in Fig. 1.
Fig. 4 a plan view of one of the'pattern plates formarking the roll.
Fig. 5 an end elevation of a modified apparatus for accomplishing the marking.
Fig. 6 a front elevation of this apparatus.
Fig. 7 a view of the marking roll and shaft detached.
Fig.8 a side elevation of a further modified apparatus for accomplishing the marking.
I marks the wringer roll, 2 the shaft of the wringer roll, and 3 the marking which is placed upon the roll which may be and preferably is in the form of a symbol, or marking in the nature of a trade mark.
The apparatus shown in Figs. 2, 3, and 4 for accomplishing the marking comprises a frame 4. This has a guide track 5 over which the wringer rolls are rolled. Along the path of the guide-way are pattern plates 6 having thereon in raised portions 1 the symbols, or mark which it is desired to impress upon the wringer roll except that the pattern is in reverse from the mark as impressed. This plate is electrically heated by any form of electric heating element 60. getting current from wires 8. The guide-way has an incoming chute 9 and above this guide-way a belt I!) is arranged which engages the rolls and advances them forward and rotatively over the guide-way and over the heating plates. The belt is carried around pulleys II. The pulleys are mounted on ,shafts I2. The shafts l2 are 'journaled in bearings I3 and one of the shafts is provided with a driving pulley l4. Along the lower reach of the belt, or that part of the belt engaging the rolls there are back plates l5 which are carried by cross plates l 6 and the cross plates l6 are carried by posts ll, these posts also carrying the journals 13 for the shafts.
In the operation of the apparatus as the rolls are passed over the heated pattern plates, the rubber coming immediately in contact with these heated portions is slightly indented and the rubber for some depth isvulc-anized to a greater ex-' tent than the surrounding rubber so that the marking can be followed below the original surallowing a blooming rubber to bloom, or by dusting sulphur on the surface. This sulphur acting under the heat is affected so as to give it a light brown color. The action may be said to be accomplished by the burning of the sulphur and the marking being effected in the rubber by a burning action, but the heat involved is not such a burning action as to seriously involve a deterioration of the immediately surrounding rubber although the mark slightly indents the surface. The effect can be accomplished by heating the pattern plate to a temperature that is usually referred to as blue bordering on a straw color, such a temperature being at, or slightly above 600 F. This heat is suflicient to convert the sulphur to a rich brown color which seems to incorporate itself with the rubber and become a substantially permanent coloring on the surface. There is thus impressed'in the rubber a slight indentation following the pattern and a sulphur discoloration of pleasing color which is-practieffective and attractive manner and at the samerights and shafts 20 are journaled in these boxes. Cylindrical pattern plates 2| are fixed on theshaft and have the pattern outline 22 thereon.
The shaft also has rotating contacts 23 and 24 arranged adjacent to each pattern plate. The pattern plates are supplied with electric heating elements and brushes 25 and 28' operate on the rotating contacts 23 and 24 and receive current from wires 21 and 28 leading to supply wires 29 and 30. Connections 3| and 32 lead from the elements of the heating p'lates through to the contacts 23 and 24 soas to supply current to the elements and the plates and contacts are properly insulated from the shaft.
A gear 33 is fixed on the end of the shaft and this meshes with a gear 34 which is supplied with a crank 35 by meansof which the shaft 20 is rotated and with it the pattern plate. A driving roll 2|! is also arranged on the shaft 20 and is adapted to drive the wringpr roll I.
A rocking support 36 is pivoted on a pin 31 extending between the posts I8. It has a socket 38 which is adapted to receive the shaft 2 of the wringer roll. An arm 39 extends from the rock arm 36 and a link 40 extends from the arm 39 to a treadle, or similar mechanism, by means of which the rocker 38 is swung upwardly carrying with it the roll into engagement with the pattern plates where the roll is rotated and receives the marking from the heat of the pattern plates acting on the rubber and the sulphur, as above described.
In the modification shown in Fig. 8 a frame having a guide post 4| is provided with an arm 42. A sliding support 43 is mounted on the post 41 and is carried by a cable 44 which extends over a pulley '45. The cable leads to a foot treadle, or other device, by means of which the block 43 may be raised and lowered.
A pattern plate 46 is carried by the block 43 and the wringer roll I is mounted on this plate.'
What I claim as new is:-
1. The method of color-marking rubber surfaces which consists in applying to the surface a sufflcient excess of sulphur and suiiicient heat to permanently color the surface alorig the lines of a pattern desired.
2. The method of color-marking rubber surfaces which consists in applying through an apof the article'forming the mark being indented and vulcanized to a greater extent than the surrounding rubber, the surface of said indented portion provided with surface sulphur for coloring purposes.
