MEIER PIERSTEIEN, or BROOKLYN, NEW YORK, ASSIGNOR T0 SAMUEL WEISGLASS, or NEW YORK, N. Y.
To ail whom it may concern:
Be it known that I, MEIER PIERSTEIEN, a subject of the Czar of Russia, residing in Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Tube-Surfacing Devices, of which the following is a specification.
My present invention relates to animprovement in machines for surfacing tubes, and is especially adapted for creating a transverse satin finish on brass tubes, such as are used in the manufacture of bedsteads.
A further object of my invention is that owing to the construction of the machine, it is not only possible to finish the surfaces of straight tubes, but is more'particularly adapted to surfacing tubes of any reasonable bend or contour, as well as being adjustable to tubes of various diameters.
In the accompanying drawings, Figure 1 is an end elevation of my device with the cover removed at the opening 11, Fig. 2; Fig. 2 is a sectional view taken on the line 2--2, Fig. 1; Fig. 3 is an end elevation; Fig. 4: is a diagrammatic representation of a curved or bent tube with the transverse surface markings thereon; Fig. 5 is a side view, slightly reduced, of the complete apparatus.
As shown in Fig. 2, the device is comprised of a pair of standards or supports l1, suitably arranged at the foot pieces 22 to be bolted or secured to any convenient stand, as by means of bolts 8-3, Fig. 2. A pair of felt guards 4-4 are suitably attached to openings 5-5 of the said side frames 11, the said guards being arranged to prevent marring or scratching of the surfaces of tubes being finished. At the upper end of the said side plates and back of the said guard members 44:, are arranged hollow extensions 6G, the same being so located to form a bearing for the surfacing pulley member 7. The cylindrical portions 6(3 have arranged thereon a pair of flanges 8--8 which are engaged in suit-- able grooves 9-9 arranged in the said surfacing pulley member 7. Suitable retaining rings 1010 are arranged in the said grooves and secured therein by any suitable means, such as pins, so as to permit the taking apart of the device when this becomes necessary.
It will be noted that the pulley member 7 is comprised of a pair of members 11 and 12.
Specification of Letters Patent.
Application filed July 27, 1912.

Serial No. 711,818.
The member 12 is recessed and has a plui'ality of bushings 13, 141, 15 and 16, which Y bushings have in turn a series of spring actuated plungers 17, 18, 19, and 20 therein. These spring actuated plungers are recessed at one end to receive therein springs 21, 22,
23 and 24. The lower ends of these plunger members are conveniently arranged so as to receive and maintain in operative position a plurality of surfacing members 25, 26, 27 and 28. These surfacing members may be composed of any suitable resilient material, such as felt, rhinoceros hide or the like, the contacting surfaces thereof being covered with a suitable abrasive, such as corundum 0r emery, held thereon by means of glue or other suitable fixative' In Fig.1 it will be noted that the.last said members are partly adapted to the contour of the tube 29, the said tube being in position for operation. From the foregoing it is obvious that the said surfacing members are so mounted as to be capable of exerting more or less tension upon the tube during the rotation of the entire pulley member 7 and its component parts in the standards 1-1, the tube being held stationary. It is also obvious that it becomes necessary when surfacing tubes of difierent diameters to retract the surface members 25, 26, 27 and 28, so as to permit the introduction of the tube to be surfaced therelietween. This is accomplished by means of a member 30, said member having a plurality of cam-like arms thereon, one for each of the said surfacing members, and each of the plunger members 17, 18, 19 and 20, are equipped with a stud or pin 31, 32, 33 and 34, respectively, the extending ends of said pins resting in their properseats on the edges of the said cam member 30. A means, such as an out-standing lug 36, is arranged upon one of the arms of the said cam member 30 in such a manner as to enable the operator to rotate the cam disk 30, thereby. forcing the pins, and with them the plungers to which they are attached,-backwardly or by moving the same in an opposite direction. permitting them to come together toward the center under the action of the springs behind the said plungers. A cover plate member 37 is suitably affixed to the cam side of the pulley member and has arranged therein a slot 38 through which protrudes the previously mentioned lug 36 in such a manner as to permit it to be engaged for operating, so as to retract or close up the surfacing members 25, 26, 27 and 28.
any convenient source of power may be utilized to cause this device to be rotated and in the drawing a preferred and simpler form is shown as being comprised of a belt 39 which may be driven from any suitable rotating means, such as a line shaft.
For the purpose of keeping the rotary surfacing on the tubes, as they are passed through the device, in a practically transverse direction, as shown in Fig. i by the lines 40, a pair of platform members 41 and 42 are arranged on opposite sides of the opening, the said platforms being adjustable up and down as indicated by the dotted slots 43, at the lower end of the platforms, and as at i t. An ordinary hex bolt 45 may be used so as to be readily lowered by the use of a wrench and the platform shifted up and down, as indicated by the dotted lines 46 in Fig. 5.
Uwing to the narrowness of the faces of the surfaces 25, 26, 27 and 28, as shown in Fig. 2, it is possible to surface tubes of very short radius of bend, as indicated in l ig. as well as ordinary straight tubes, and while the platforms 41 and 42, Fig. 5, are not absolutely necessary for surfacing straight Work, it is obvious they are very useful when surfacing tubes of the contour shown in Fig. 4.
Having thus described my invention, 1 claim 1. .ln a surfacing device comprising a frame having a journal portion, an annular member rotatable in the journal of the frame, a series of surfacing elements in the interior of the annular member, and means for simultaneously adjusting the surfacing elements in a radial direction.
2. ln a surfacing device comprising a frame having a journal portion, an annular member rotatable in the journal of the frame, a series of surfacing elements in the interior of the annular member slidable in a radial direction, springs for forcing the elements toward the axis of the annular member, and a member engaging each surfacing member to limit its inward movement, said limiting member being shiftable to simultaneously vary the limit of inward movement.
3. A. surfacing member comprising a ring member, a pair of supports having means engaging the interior of said ring member on opposite sides thereof respectively to form a bearing for the ring to permit the the ring having a series of radial channels in its interior, a plunger slidable in each channel and carrying a surfacing body on the inner end so that all cooperate to err gage an article inserted therebetween, a ring carried by the said ring having cam faces, a pin on each plunger engaging the cam faces respectively and a spring on each plunger forcing it inwardly to cause the pin justable to vary the position of the plunger-s.
