GRINDING OR POLISHING MACHINE.
SPEGIFICATION forming part of Letters Patent No. 765,105, dated July 12, 1904.
Application led February 21, 1902. Serial No. 95,042. (No model.)
To all whom, it may con/067%:
Be it known that I, MICHEAL SETTER, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grinding or Polishing Machines, of which the following is a specification.
My invention relates to machines for polishing various substances or materials and different articles of manufacture, and particularly to machines for polishing carbon. For example, in the manufacture of telephonetransmitters it is the practice to provide these instruments with highly-polished electrodes, usually in the form of small disks of carbon, having their opposing surfaces, as stated, highly polished. It is important that these disks or. carbon electrodes be given a high polish and also that the polished surfaces be vperfectly at and even and without flaws or scratches.
It is the object, therefore, of my invention to provide an improved machine whereby any substance or article of manufacture can be given a smooth and evenly-polished surface, and particularly to provide an efficient machine for polishing' the said carbon electrodes for telephone-transmitters.
A special object is to provide an improved construction and arrangement whereby a number of Athese carbon disks or electrodes can be polished or operated upon at the same time.
Another object is to provide an improved construction and arrangement whereby the disks or electrodes can be readily inserted in and removed from the machine.
A further object is to provide an improved construction and arrangement of relatively movable members whereby the direction of the abrasive or polishing action on the carbon is constantly changed, so as to insure highly polished surfaces without scratches or grooves.
It is also an object to provide certain details and features of improvement tending toV increase the general efliciency; and to the foregoing and other useful ends my invention consists in matters hereinafter set forth and claimed.
In the accompanying drawings, Figure l is a side elevation of a polishing-machine embodying the principles of my invention, the receptacle for holding the water and which incloses the polishing-wheel being shown in section. Fig. 2 is a plan of the machine lshown in Fig. l. Fig. 3 is a detail plan of the rotary holder which carries the carbon. Fig. 4 is a detail section through the said holder on line l 4 in Fig. 3. Figs. 5 and 6 are large detail views showing the pivotal connection between the body of the machine and the arm upon which the rotary holder is mounted.
As thus illustrated, my invention comprises, preferably, an uprightA standard or body structure A, adapted to support the operative parts in a suitably-elevated position. y The rotary polishing or abrading wheel B is preferably mounted on top of this standard or body structure and arranged to rotate about a vertical axis. As a simple and eiicient arrangement for rotating this polishing or abrading wheel, the latter can be provided with a downwardly-extending spindle L, and this spindle can be provided with a belt or pulley o. This spindle has a bearing a in the upper portion of the standard or body structure and is provided with a step-hearing b2. This step-bearing is adjustable, so as to permit the wheel B to be raised and lowered slightly. Preferably the said wheel is inclosed by a receptacle C, which is adapted to hold the water usually employed in grinding and polishing operations of this character. The rotary holder D is also arranged for rotation about a vertical axis, and is preferably carried by a swinging arm d, which is a part of the standard or body structure. As a meansfor communicating power and motion from the driven polishing-wheel to said rotary holder the upper end of the Spindle I) can be provided with a pinion b3, adapted to engage an idler (Z2. This idler, it
will be observed, is also carried by the swinging arm Z and is arranged to engage the gearwheel d, mounted on the upper end of the spindle which carries theholderD. The said holder, it will be observed` has a fiat under side adapted to rest upon the upper surface of the rotary or abrading wheel B. Then the abrading or polishing' wheel is driven, power is transmitted through the said g'earing to said holder, and the latter is rotated about its axis. rlhc said holder is preferably provided with carrying pockets or openings cli, adapted to receive the carbon disks or eleetrodes,and also with springs d, which are adapted to bear upon and hold the said disks or carbon electrodes firmly in contact with the polishing' or abrading wheel. The arm earrying the holder can be locked in the position shown in the drawings by the locking-pin d, which is adapted to engage a socket in the pivoted end of the said swinging arm. It will be readily understood that the rotary abrading or polishing wheel B can be .of any suitable substance or material, accordingI to the degree of polish desired and in accordance with the materials or substances to be operated upon. rl`hus constructed the machine can be employed for grinding' or polishing diiiferent articles-fas, for example, the disks or carbon electrodes involved in the construction of certain kinds of telephone-transmitters. These disks or carbon electrodes, as stated, are placed in the pockets d", and the belt around the pulley 7/ is then started for the purpose of rotating the abrading' or polishing' wheel B. The rotation is also communicated to the carrier or holder D, and in this way the direction of the abrasive or polishing' action on the carbon is constantly changed. This prevents the abrading' or polishing wheel from scratching' or cutting grooves in the surface of the carbons and insures a perfectly smooth and iiat surface having a high polish.
lf claim as my inventionl. The combination of a rotary polishing'- wheel, a vertically-swinging' arm,a rotary disk mounted upon said arm and arranged at one side of the center of said wheel and provided with devices for pressing' the articles to be polished against the flat upper surface of said wheel, and gearing whereby the wheel and disk rotate in the same direction.
