Stearman, Enid; Okla; assignor to Stearman Aviation, Inc., Enid, Okla, a'corporation of Oklahoma Application July 14, 1943, Serial No.-494,727 4 Claims. c1'.51- '1s) This invention relates to new and useful improvements in the art of sandblasting objects and more particularly to a turntable upon which the article to be sandblasted or otherwise treated is supported. I
- An important object of the present invention is to provide a turntable for supporting articles to be treated whereon a number of article supto provide a turntable of the character stated which can be manipulated either from manual or powdered means and wherein means is provided permitting the turntable to be tilted when the need arises.
-Other objects and advantages of the invention will become apparent to the reader of the following description.
In the drawings: Q
. Figure 1 represents atop plan view ofthe powered form of turntable.
Figure 2 is a side elevational view with a'portion in section, showing the'form of the'invention disposed in Figure 1.
Figure 3 is a fragmentary vertical sectional view through the central .portion of the turntable. Figure 4' is a fragmentary elevational view showing the means' for rotating the individual article support.
Figure 5 isa fragmentar vertical sectional view through the upper portion of one of the individual article supports.
Figure 6 is a fragmentary top plan view of the manually operated form of the invention.
Referring to the drawings wherein likeg numerals designate like parts, it can be seengthat numeral 5 generally refers to a supporting frame having end structures 6, 6, each provided gwith a bearing 1 at its upper portion. Numeral 8 denotes a bar-like swing or cradle member of substantial U-shape and having trunnionsg, .l l
all
Rising from the intermediate portion of the,
swing member 8 is a neck 13, flanged at its upper end as at 14. Numeral l5 denotes a substantially large horizontally disposed wheel 'upon the central portion of which is located a plate l6. Bolts n pass downwardly through thc'plate l6 and wheel l5 as well as the flange I4 and are equipped-with nuts it. Thus the wheel I5 is positively secured to the neck I3 and also has an upstanding stationary stub-shaft [9 which projects upwardly into a vertical sleeve ZUwhich is closed at its'upper end as at 2 I The lower end of this" sleeve extends downwardly through an opening 22 in a turntable 23 and may besecured. to. or formed integral with a plate 24 which is secured to the underside of the turntable 23 by bolts 25.
Fulcrumed upon the trunnion II, as shown;
in; Figure 2, is. a substantially diamond-shaped frame 26fthe same being fulcrumed as at 21. A flexible shaft in 'a conduit 28 extends through this frame and the shaft'is journaled through a bearing 29 to a drive roller 30 which rides a rim 3| at the periphery of the turntable 23. A brakeblock 32 is supported by the frame 26 just under. theroller 30 by a bracket 33. A spring 34 is provided between the bracket 33 and the swing member 8; as shown in Figure 2, to serve topull the roller30 downwardly into driving engagement with the rim 3|.-
A cable or like member is attached to the eye end 35 of the frame 26, to the end that when desired, the frame 26 can be rocked, to lift the corresponding portion of the shaft 38 above the barrel 3! is disposed a cross pin or bolt 4|, which obviously rides the upper end of the barrel 31 as the shaft 38 rotates. Obviously, articles are disposed over the support'36'orfin any way desired carried by the upper end of the shaft 38, so that they will rotate individually as the turntable 2a is rotated by the drive roller 30.
A V-shaped rim 42 is provided on the wheel l5 and this engages in the 'V-grooves 0f the wheels 39 and serves to rotate these wheels and their corresponding article supporting shafts 38.
A modification of the invention is shown in Figure 6 and this represents a manually operated mechanism. In this form of the invention the reference character 5a denotes a frame structure having end structures 6a equipped with bearings i trunnion Ila, which is hollow, and connects to 10 one end of the bellcrank 4B. The other end of the bellcrank 46 is connected by a spring 49 to an arm 50 projecting from the trunnion Ha and this same end of the bellcrank 46 i provided with a pivotal pusher element 5| forengaging teeth 52 at the periphery of the turntable 23a.
The cable 41 may extend to a crank 53 at one end of an elongated shaft 54 equipped with a treadle 55. Obviously, a pull on the cable 41 will rock the bellcrank 46 and exert a push on the pusher element 5| which will effect a movement to the turntable 23a. Continual operation of the cable 41 will maintain the turntable 23 rotat- While the foregoing specification sets forth the invention in specific terms, it'is to be un-' derstood that numerous changes in the shape, size and materials may be resortedvto without departing from the spirit andscope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is:
ing movement thereof, article supports on the I shaped cradle member having end trunnions prising a. rotatably mounted turntable, article supports on the turntable and means for driving the turntable, said drive means comprising a rockable frame, a shaft extending into the frame and provided with a drive roller for engaging a peripheral portion of the turntable and means for rocking the frame upwardly to disengage the roller, and a brake element carried by rotatably mounted to rock about an horizontal an upstanding member in the center of the cradle member, a wheel fast on said upstanding member, a turntable rotatably mounted on said wheel to be driven relative to the same,- article supporting memberson said turntable .rotatably mounted in the turntable, friction drives between said article supporting members and wheel whereby said article supporting members are rotatable aboutaxes under rotation of the tumtable relative to the wheel, and means to rotate said turntable mounted on said cradle member to swing therewith.
4. In apparatus of the class described, a U- shaped cradle member having end trunnions rotatably mounted to rock about an horizontal axis whereby said member is swingable laterally, an upstanding member in the center of the cradle member, a wheel fast on said upstanding member, a turntable rotatably mounted on said wheel to be driven relative to the same, article supporting members on said turntable rotatably mounted inthe turntable, friction drives between said article supporting members and wheel whereby said article supporting members are rotatable about axes under rotation of the turntable relative to the Wheel, and means to rotate said turntable mounted on said cradle member to swing therewith comprising a. spring loaded frame vertically swingable in opposite directions, respectively, on said cradle member, coacting friction drive devices on said frame and turntable, respectively, rendered inefiective by swinging of said frame in one direction, and brake means on said frame operative against said turntable under swinging of said frame in said one direction.
