HARLES-r. MOTZ, or MONAQA, PENNSYLVANIA.
SAiND-BLAST MACHINE.
' To all whom it may concern I Be it known that 1,
CHARLES F. Mo'r z, a citizen of the-United States, and residcntof Monaca, in the county of Beaver and-State of Pennsylvania, have invented anew and I useful Improvement in Sand-Blast Machines;'-and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to sand blast ma chines, and more especially to a class ofmachines for sanding or frosting glassarticles.
.Heretofore, in the operation of san'drblasting glassware, such as shades and globes, the
article to be sanded interiorly has been op- "This drum-is supphed with air at suitable pressure for the sanding operation, and 'for erated on singly, and generally in separate mach nes; in some instances of exterior sanding of such articles, a pair of artlcles have been operated on simultaneously in a single machine.
The present invention aims to provide a sanding machine in which a large number of pleces of ware are simultaneously operated on, and in whlch the operatlon of feeding the ware to, and removing the ware from the machine is. of a continuous character,
from a fixedposition. That is to say, the
pieces to be operated on, and the finished pieces, are fed by the operator to the machine and removed therefrom separately,in succession and alternate fashion.
A further object of the invention. is to provide a machine of the above character. in which all Of the ware is handled at one point of the machine.
A further object is to provide means for the automatic regulation of the air blast for sanding and for other operations of the machine.
, The invention consists in the novel features of construction and in the combination and arrangement of parts hereafter described. I
The invention is illustrated in the'accompanying drawings, in which Figure 1 is a vertical sectional view of my machine; Fig.
2 isa plan view; Fig. 3 is a horizontal sec-v tion and part plan View of the sanding hopper, showing the flexible sanding nozzles; Figs and dare-enlarged detail views of "automatic devices for actuating-the valves controlling the supply of air to the machine;
6 is a detail of one ofthe above-mentioned valves for'controlling the supply of air a cylinder for raising and lowering Specification of Letters Patent.
' Application filed Api-il9, 1917.- Serial No. 160,708..
of the receptacle is covered with a revoluble w'are-carryingplate 4 which is supported on and rotated by a vertical shaft 5. The shaft is j ournaled in the standard centrally of the receptacle, and is driven'by the worm-gearing 6, Secured to an extension of the shaft above the cover-plate is the air-drum 7.
other operations, as'will hereinafter be described. The air enters the drum through Drum 7 forms a bearing for the support of a spider-member 10 to which is fastened the main ware-revolving gear 11.
Thespider is rotated by a tubular shaft 13 which is fast to the spider and is driven by gearing 12.
The ware-table or cover-plate 4 is pro- 'vided with a number of openings 14; these openings ,are uniformly spaced apart, and he in a circle concentric with the spur-gear 11.. Each opening represents a ware posi{ tion of the machine, and in this instance,
six of such positions are shown. It may be desirable with some kinds of ware to provide a machine with a greater or a less number of ware positions, and Ida-not wish to limit my invention to any particular machine capacity. Each opeii'ing forms a circular bear- PatentedOct. 1.1919
section of the swivel carrier or,
ing into which is fitted a ware-revolving gear 15, the gear ofeach opening meshing with the main drive-gear 11-. These gears are provided with internal flanges 16 for the support of .a ware-supporting member or seat, 17 Thisseat, preferably, is a wooden plate or disk formed with a central opening 18, through which the sand blast is directed, and in the particular instance illustrated the seat is adapted to support an inverted lobe for internal sanding. Modification o the opening adapts this seat'fo'r. use for external sanding. For instance, the ware may be fitted into or suspended from such an opening to be acted on by the sand blast. Other forms of seats and means for centering and supporting the ware may be used, and I do not wish to restrict the invention to any paron the piston-rod'20 ticular form of Ware support.
The ware is he d to its seat during the sanding operation by an air-actuated holder 2-2, which is adapted to be raised and lowered automatically at the operators'stand for the removal of the sanded piece, and for replenishing the holder as the revolving;
table brings each ware-holder in succession to this position. The holder is actuated by an air cylinder 20. A cylinder 20 is prO- vided .at each ware position of the machine, thepiston-rod of which carries the holder.
The holder comprises a plate or disk 22 provided with cushioning means 22, and has the spring fingers 23 for gripping the ware, as clearly shown in Fig. 9. The holders are detachable, and are made in va-- rious forms and sizes to suit the different kinds of ware for which the machine is adapted. A sleeve 24 and bolt 24? connect the holder to a swiveling connection 25 i This connection i loosely journaled on the piston-rod and 'bolt 2%,and is adapted to rest on the sleeve of theholder during the sanding operation or when the holder is lowered to act as a weight g to hold the ware to its seat. By the above arranged connection, it will be seen that the seated ware is free to rotate as the. gear 15 rotates, Cylinders 20 are mounted on cesses is adapted when the plug is turned to operative position to form a communicat ing passage'between the inlet and one end of the cylinder 20, while the other recess forms a passage between the exhaust pas-' sage 32 and the opposite end of the cylinder.
When the plug is turned to the position as shown in Fig. 6, air is in communication with the top of the cylinder above the piston, and this figure represents the position of the valve-plug when moved to admit air to the cylinder to lower the holder. Air
' is maintained within the cylinder above the 'piston as long'as the valve remains in this position. The valve is provided withan operating arm 35, controlled by a spring 36.-
Mounted on the machine near the operators stand-is a stationary cam-plat 37. IAsthe table-rotates carrying thevalve with it, the' operating arm of the valve is brought into engagement with the cam-plate causing the arm to rotate the plug of the valve so as to bring into register the ports of thevalve which communicate with the bottom of the cylinder, causing the ware-holder to be elevated, displacing the air above the piston byexhausting through port 32, and thus providing cushioning means for the upstroke of the piston. The wareholder remains in elevated position as long aS-the valve-ar1n rides on the cam-plate, the plate being of such length as to providerample time for the operator to remove the sanded piece and insert into the holder a piece to be operated on before completion of travel of the arm over the plate. When the arm has moved off the plate, the spring 36 acts to return the plug of the valve to its normal position, directing air again into the top of the cylinder to lower the ware-holder in position for the sanding operation. It will be noted, air is maintained in the cylinder above the piston during the'sanding operation or for, that part of the revolution of the table when the arm of the valve is'not engaged bythe camplate" 37. Other valve structures may be employed to actuate the holder inwhich the air is cut off during the sanding operation, but I prefer to employ the structure as'shown, as in this instance,
- air is always instantly available for cushioning the upward stroke of the piston. Obviously, the vair maintained in the cylinder above the piston during the sanding operation may be employed to act as means for holding the ware to its sea-t, without change in the above-described structure of the cylinder and holder, in which case, the swivel connection acts as supplemental means for holding the ware down in case of cylinder leakage, and it is to be understood the invention contemplates the employment of such an air-actuated ware-holder.
' The sanding mechanism includes suitable sanding nozzles carried by the table beneath the ware-openings, and adapted to direct the sand as the table revolves so as to act on all portions interiorly of the ware. The
mechanism as illustrated inFigs. 1' and 5 comprises the air-pipe 40, which is 'suspend- -ed from a swing-joint 41 connecting to a pipe 42, which passes upthrou'ghthe table andis-tapped into. the air drum 7. Pipe 40 terminates. in a,T-union'43 to which the nozzle 44; is attached. This. union also has carries the sand suction-head 46.
The principle of sand ejection .is'as follows: p
Air is admitted topipe 40 from the pres- .sure drum 7 by opening a valve 47, mechanism being provided at a point near the operatorsstand for opening. the valve which is adapted to operate automatically after the ware is seated on the revolving table,
' attached thereto the flexible hose 45 which as hereinafter described. Air in passing through the union and nozzle to the atmosphere creates a vacuum in hose 43, which causes the sand to be drawn into the hose and into the current of air passing through the union, and ejected through, and directed by, the nozzle onto the Ware, all in a manner which is Well understood. -Various other sanding nozzle constructions may be employed and I do notwish to'restrictthe in- .vention to any particular .type of nozzle= These sandingnozzles are adapted to be '15 automatlcally controlled.
moved automatically so as to direct the stream of sand to act onall portions of the revolving ware, and the air for the blast is In Fig. 7 the sanding nozzle is illustrated in full and dotted lines indicating the swing or movement of'the nozzle to direct the sand to all portions interiorly of the. globe. To
' accomplish this movement astationary camtrack 48 is provided upon which the pipe l0 is adapted to travel, a roller 40 surrounding the pipe to relieve the pipe of Wear. track is stationary and is detachable, and is made of various forms for various kinds of.
ware. The -.track. as shown has astraight portion 48 which maintalns' the nozzle at the correct angle to direct the sand, inthe instance shown, to approximately half the.
height of the globe. As the table revolves the nozzle is carried off the straight portion and rides down'the inclined end 48 of the track to the position as shown in dotted lines, in which position it is held suspended at the swing-joint by an adjust ble chain 19 for directing the sand at the right angle to operate on the remaining. unsanded portion of the globe. ,The nozzle remains in this suspended position. until the revolving table brings it in contactrwith the opposite inclined end 48 of the cam-track whereupon it is brought again 'in position on the straight portion of the track. Completion of-travel of the nozzle on the straight portion'of the track completes the sanding operation; At 7, or near this position, the air-blast for sand-. ing is cut-ofl automatically, and the ware ele yated,"and removed from the holder, and
unsandedware-placed in the holder to be operated on. These operations take place as the table revolves," and when the unsanded ware is-low'ered intoposition, the table has moved so thatthenozzle is again} insuspended'position, and the air'is automatically,
turnedon for the'sanding operation. The mechanism for automatically controlling the sanding air comprises a bracket 50 located on the table near"eachwareposition. To this bracket is attached a bell-crank 51, one arm of which connects -by a rod .52 to an valve is asimpleplu'g-ya'lveor cutout cock and movement'ofthe arm 1n one dlrection turns on the air, and the reverse movement This cuts the air off. The bell-crank has an arm 54 which is adapted to be engaged by tri-p perwheels arranged in the path of the travel of the arm as the table revolves. The Wheels are mounted on fixed brackets 55 attached to the machine.
One of these Wheels- 56 is located in such position as to engage the arm of the bell-crank near the end of the travel of the nozzle over the straight. portion of the track. The Wheel being so positioned in respect to the arm as to cause the arm to be drawn under the wheel and depressed, the movement of the bell-crank at this time closes thevalve 4.7 and shuts off air to the sanding nozzle. As the table continues to turn, new Ware is inserted, and the holder lowered. The bell-crank having moved with the table is brought to a position where'the 'arm'54 is engaged by the wheel 57. The
arm at this position riding up over the wheel'movesthe arm of the valve to. turn I on the air for the'beginning of the sanding operation.
From the foregoing description of the machine and its operation it will be seen that I have provided a machine which by its automatic operation greatly facilitates'the handling of Ware. The continuous, successive operation of removing the finished ware and replenishing the machine from a fixed position as the machine rotates results in a large saving of time and in increased out-' put, as compared with the common practice Also, there are advantages i the'rotation of the table, sanding mechanism, and means for operating the sanding mechanism to sand the-ware of each support separately' throughout its movement on the table.'
