To mZZ whmn itpmy concern: I
Be it known that-LJoAonIM Irnason, a subject of theKing of Sweden and. Norway, re-
sidingatlndianapolis, in the county of Marion andstateof Indiana, have invented certain. new and useful [Improvements in. Pneumatic Bag Turning Machines, oi which the followhigh a specification.
-. The object of my invention is to providean' improvement in means for pneu matically turn- 1mg bags by an air-blast insteadof an air-suetion, as has heretofore been customary.
The accompanying drawing," which is a cen- .tral vertical section ofa machine embodying my invention, clearly illustrates the same.
The machine consists of an air chute or caslng 10, at the mouth of which are arranged suitable bag opening and supporting fingers 11, over which the mouth of the bag is to be placed. Atthe rear or discharge end of the casing is a roller 12, which is continuously rotated in the direction indicated by the arrow by any suitable means. Arranged above a roller 12 is a coacting roller 13, which is jour naled on the upper ends of sliding arms 14, which may be moved up and down by means y of a cam 15, so that roller 13 may be moved firom and toward roller 12, for a purpose which is sleeved the lower end of a suitable supply blast-pipe 25, the arrangement being such that the spout 22 may be swung upon its pivot without disconnecting it from tube 25.
Mounted in pipe 25 is a suitable valve 26, which is arranged to be automatically oper ated by a link 27' and an arm 28, the arm 28 carrying a roller 29, which is engaged inter- The shaft which carries cam 15 also carries a cam 31., which is adapted to operate a suit able delivering-fly 32 in a well-known manner. in operation the normal position of the parts is that in which roller 13 is down against roller 12, fingers 11 are thrown inward toward the medial line of the receiving end of casing 10, and spout 22 is thrown upward away from said receiving end. With the parts in these positions the operator places the mouth oil a bag over lingers 11, and a rotation of the cam 15 by its shaft throws roller 13 up to the position shown in the drawing, spreads fingers 11, drops spout 22 to the position shown,
where it may delivera blast of air onto the bag and into the casing 10, and opens valve 26 so as to allow such blast of air to pass through pipe 22, the several movements taking place in the order named. The blast of air coming from spout 22 strikes the outer side of one wall of the bag and turns the bag and blows the same into casing 10, whereupon roller 13 begins to move toward roller 12, and valve 26 is closed. The further movement of roller 13 downward withdraws cam 16 from arm 17 so that fingers 11 return to normal position, spout22 is thrown away from casing 10, and the bag is grasped between the two rollers 12 and 13 at or near the closed end or bottomand by them delivered to the fly 32,
whereupon the operation is repeated.
It may be desirable under some c1rcumstances to cause the blast-tube to follow the turning bag, so that the blast may be more directly applied at the point of turning. For that purpose the discharge end of the tube 22 is sleeved upon the rear end and-connected by a link 33 with a lever 34, engaged by a properly-timed cam 34, so that the discharge end of the blast-tube will follow the turning bag into the. casing. I
The method of turning bags pneumatically, which may be effected by the use of the abovedescribed machine or by hand, is embodied in a companion application, Serial No. 174,041, filed September 21,1903.
mittently by a cam 30, carried by arms 14. 1 The guard 13 is located in front of the roller 13 and parallel therewith anc serves to guide the rear end of the turned bag to pass between the rollers 12 and 13.
1, In a bag-turning machine, the combination,with a receiving-casing against the mouth of which a bag may be supported, of a blasttube mounted to discharge a blast of air into the mouth of saidcasing, for the purpose set forth.
2. In a bag-turning machine, the combination, with means for supporting the mouth of abag,of a blast-tube arranged to direct a blast of air upon one'side of said bag toward and through the mouth thereof.
'3. In a bag-turning machine, the combination, with a receiving-casing having an opening adjacent which the mouth of the bag may be supported, of a blast-tube arranged to direct a blast of air into said opening, for the purpose set forth.
4. In a bag-turning machine, the combination, with a receiving-casing having an opening adjacent which the mouth of the bag may be supported, of a blast-tube arranged to direct a blast of air into said opening, and means for discharging the turned bag from the end opposite said opening.
5. In a bag-turning machine, the combination, with means for holding a bag-mouth distended, of a blast-tube arranged to direct a blast of air upon one side of said bag toward and through the distended mouth thereof from the closed end of the unturned bag, and means for moving said tube in the direction of turning at the time of turning.
6. In a bag-turning machine, the combination, with means for supporting and distending the mouth of a bag, of a blast-tube arranged to direct a blast of air ,upon one side of said bag toward and through the mouth thereof. V

8. In a bag-turning machine, the combination with a receiving-casing having an opening adjacent which the mouthof the bag may be supported and distended, of means for supporting and distending the mouth of a bag adjacent the mouth of the casing, and a blast- ,tube arranged to direct a blast of air into said opening, for the purpose set forth.
