My glove turning machine, the preferred design of which is illustrated in my drawing, cornprises finger tubes I0, finger rods I! and a stripper plate I2 normally disposed about the finger tubes III. The finger rods I I are reciprocally movable in a first direction into the ends of the finger tubes I and in a second direction out 'itsnormal position in the second direction to a position about the finger rods II and then in the first direction to its normal position.

v The finger rods II are reciprocally moved in the first and second direction by an air pressure operated cylinder, designated in m drawings by the letter B. The stripper plate I2 is similarly moved reciprocally in the first and in the second direction by an air pressure operated cylinder, designated b the letter A inmy drawings. The finger tubes I0, and the cylinders A andHB may be supported in cooperative relationship by a suitable framework 53. v.

The finger rods II are carried by a piston rod I4 which extends from and is actuated b the cylinder B. The finger rods II and, the finger tubes! are constructed of a length whereby they may cooperate to turn the fingers 26 of, the glove I 9 inside out. without ripping the glove. The stripper plate I2 is carried by a piston rod I5 which is actuated by the cylinder A. The finger rods I I are kept in alignment .by an align ment guidefarm- IB. This arm fastens the-fin; ger rods II to the piston rod I4 of cylinder-"-13 and is reciprocally movably mounted on the pis ton rod I5 of cylinder A. Th stripper plate I2 iskept in alignment by slot means 30 which engage a slide projection 3| of the framework I3'.

It is to be understoodthat although I describe the parts of thestructure of my preferred glove turning mechanism with a certain degree of particularity, numerous changes and details may be incorporated therein without departing from the scope of my invention.

The finger tubes I and finger rods II in my preferred glove turning machine are placed in a position to accommodate either a left-handed glove or a right-handed glove, as is best illustrated in Figure 3. The finger tubes I0 comprise individual finger tubes 80, 8I, 82 and 83 placed. in a straight line with a thumb tube 84 placed between the end finger tube 80 and the next adjacent and finger tube 8| of this line of tubes and in front of this line of tubes. For a glove for the opposite hand the thumb of the glove 'is placed over a thumb tube 85 located directly behind the line of finger tubes 80, 8|, 82 and 83.

The actual turning of a glove inside out may be best explained by referring to the Figures 4, 5, 6 and 7 of my drawings. I designate a glove I9 as having fingers 20 and a wrist body portion H. To turn the glove I9 inside out the operator places the glove I9 over the finger tubes J0. A finger tube IEI extends into each and every one of the fingers 20 of theglove I9. The wrist body portion of the glove extends toward the stripper plate I2 which is normally positioned about the finger tubes I0. When the operator has placed the glove I9 over the finger tubes I0, he merely has to move a lever 66 to start the operation of the glove turning. machine which will completely turn the glove I9 inside out.

The finger rods II are moved in the first di rection into the finger tubes I0. As each individual finger rod moves into its respective finger tube, it engages the end of the finger which is over that tube and pulls thefinger into the tube, thus turning the finger inside out. The position of the glove l9 on my glove turning machine just after the fingers have been pulled into the tubes is illustrated in Figure 5. V

The next step in the operation of my glove turning machine to turn the glove I9 completely inside out is to move the stripper plate I2 in the second direction from its normal position about the finger tubes Ill to a position about the finger rods II. The finger rods II are held in the finger tubes In to hold the fingers 20 of, the glove therein while the stripper plate I2 is moved in the second direction to turn the wrist body portion 2| of the glove I 9 inside out. Figure 6 of my drawings best illustrates the position of the finger tubes II], the finger rods II, and the stripper plate I2, just as the stripplf plate has stopped moving in the second direction to turn the wrist body portion H of the glove I9 inside out.

The stripper plate I2 must now be movedin the first direction past the glove I9 to its normal position about the finger tubes II]. To permit the stripper plate I2 to move past the glove I9 without catching the wrist body portion 21 thereof and bunching the glove up or ripping it, I have constructed the stripper plate I2 with two half portions 25 and 26. These half portions 25 and 26 are normally disposed to lie substantially in a plane to form a fiat surface with the center portion cut out whereby they may extend about the finger tubes II]. The half portions 25 and 26 may be fastened to a perimetrical support means 2'1 by hinges 28. The perimetrical support 21 extends about the finger tubes Ill and is carried by the piston rod I extending from cylinder A. The half portion 25 is hingedly fastened on one side of the finger tubes l0, and the half portion 26 is hingedly fastened on the opposite side of the finger tubes l0. As shown, springs 29, fastened by welding or other suitable means to the support 21, hold the half portions 25 and 26 in substantially a fiat surface. It is understood that any suitable perimetrical support 21 and hinge 28 together with a spring 29 may be employed for the purpose of normally holding these half portions 25 and 2B in a substantially fiat plane to produce the stripper plate I2.

As this stripper plate l2 moves in the first direction past the glove I9 and to its normal position about the finger tubes I0 after turning the wrist body portion 2I of the glove I9 inside out, the half portions 25 and 26 separate to increase the distance therebetween to permit the stripper plate I2 to travel over the glove I9. As soon as the stripper plate I2 has traveled past the glove I9, the springs 29 cause the stripper plate half portions 25 and 26 to return to their normal positions constituting substantially a fiat plane. This hingedly separating of the half portions 25 and 26 of the stripper plate I2 prevents the stripper plate from riping or damaging the glove I9 as it travels in the first direction to its normal position about the finger tubes I0.

When the stripper plate I2 has again reached its normal position about the finger tubes I 0, and the glove is completely turned inside out, the finger rods II move in the second direction out of the finger tubes Ill and to their original position, as is illustrated in Figure 70f my drawings. The operator may remove the glove from the glove turning machine after the finger rods II have moved in the second direction from the finger tubes It! to their original position.

The finger rods II are terminated in ballshaped knobs I! which engage the ends of the fingers 20 of the glove I9. The knob provides for a large end of the finger rod to engage the end of the finger without the finger rod filling up the tube and thus prevent injury or damage to the glove finger as it is being pulled into the finger tube. The finger of the glove may partially crumple about the finger rod above the knob as it is being pulled into the tube.

The pressure system for operating the cylinders A and B to cause the glove turning machine to turn the glove I9 placed thereon inside out may best be described by referring to Figure 8 of my drawings. Although other pressure'systems, such for example oil pressure, may be used, I have found that air pressure is the most convenient and satisfactory for my glove turning machine. This air may be supplied by an air pressure supply line 57 from any suitable air pressure unit.

My preferred air pressure control system which operates the cylinders A and B, comprises in general a master control valve 55, a valve 5I,'a trip valve 52, a first sequence valve 53 and a second sequence valve 54, all of which are connected by suitable conduits to form the system. I have illustrated my preferred control system for the air operated cylinders A and B symbolically in Figure 8 of my drawings. The master control valve 59, illustrated symbolically in my drawings, has an inlet opening 55 connected by a conduit 56 to the air pressure supply line 5 The master control valve 58 also has outlet openings 58 and 59 and an exhaust port 69. The valve may be said to be a two-position valve. When the valve is in the first position, the inlet opening 55 is connected with the outlet'opening'58; and the outlet opening 59 is connected with the exhaust port 60.

When the valve is in the second position, the inlet opening 55 is connected with the outlet opening 59, and the outlet opening 58 is connected with the exhaust port 66. A conduit 6|, connected to the top of cylinder A and to the outlet opening 58 of the master control valve 50, transmits air therebetween. A conduit 64 connects the outlet 59 of the master control valve 50 to the top of the cylinder B.

An air pressure operated valve positioner 62 is connected by suitable mechanical means, as illustrated by the dash-dot line 53, to the master control valve 50 to position the master control valve 50 in the first or in the second position. The valve positioner 52, which positions the master control valve 50, is illustrated in my drawings as a cylinder with a suitable piston movable endwise therein. The piston is mechanically connected, as is symbolically shown by the dash-dot line 63, to the control portion 14 of the master control valve 50 for positioning the control portion 14 in either the first or the second position. In actual practice, the master control valve 50 and the valve positioner 52 may be constructed as a single unit.

The valve 5i has an inlet opening, an outlet opening and an exhaust port 61, and may be operated by the lever 65 or other suitable means. The inlet opening is connected to the supply line 51. The outlet opening is connected by conduit 65 to one end 32 of the valve positioner 52. When the valve 5| is not held in open position to connect the valve positioner 62 directly to the air pressure supply line 51, the valve connects the conduit 65 and thus the valve positioner 52 to the exhaust port 61.

The trip valve 52, also shown diagrammatically in my drawings, has an inlet opening 58, and an exhaust opening III. The valve is operated through suitable mechanical means, illustrated in my drawings by dash-dot lines II, the cam 34 and the boss 35, by the movement of the stripper plate I2 carried by the piston rod I5 extending from cylinder A. The boss 35 is fastened to the stripper plate I2, and the cam 34 is fastened to the framework I3. When the stripper plate I2 moves past the cam 34 the boss 35 moves the cam 34 to operate the trip valve 52. The inlet opening I58 of the trip valve 52 is connected directly to the air pressure supply line 5?. The outlet opening 69 is connected by a conduit I2 to the opposite end 33 of the valve positioner 52.

The first sequence or relief valve 53 is connected by a conduit I6 between the top of cylinder A and the bottom of cylinde B. The second sequence or relief valve 54 is similarly connected by conduit 73 between the top of cylinder B and the bottom of cylinder A. These sequence or relief valves 53 and 54 may be any suitable relief valve which will permit air to pass through the valve only after the pressure of that-air has reached a desired value. In my drawings, I have illustrated the valves symbolically and do not intend to limit the scope of my invention to the strict design of any particular valve used in my air pressure system.

In the operation of my glove turning machine, the operator places a glove I9 over the finger tubes l9 and raises the lever 66. The lever 66 operates the valve 51 permitting air to fiow from the air pressure supply line 51 through the conduit 65 and into one end 32 of the valve positioner 62, thus moving the piston I5 endwise therein. The valve 5| may be restored to its the valve 15 has moved endwise. When the pis ton 15 in the valve positioner 62 is moved endwise, the control valve portion I4 is moved to the second position, and thereby permits air to pass from the air pressure supply line 57 through the conduit 56, the inlet 55, and outwardly through the outlet 59 into the conduit 64 and the top of cylinder B. The pressure in the conduit 64 and also in the top of the cylinder. B builds up, thus forcing the piston rod I4 downwardly or in the first direction to move the finger rods I I into the finger tubes ID for pulling the fingers 20 of the glove I9 therein.

The valve 5 I, upon being returned to its normal position, exhausts the conduit 65 andthe one end 32 of the valve positioner 62 through its exhaust port 61. When the pressure in the cylinder B has built to a pressure substantially equal to the pressure of the air supply line 51, the second sequence or relief valve 54 operates to permit the air to enter the bottom of cylinder A through conduit 13. The air entering the bottom of cylin-, der A causes the piston rod I5 to move upwardly or in the second direction, thus causing the stripper plate I2 to move from its normal position about the finger tubes I I and thereby turn the wrist body portion 2| of the glove I9 inside out.

In turning the wrist body portion of the glove inside out, the piston rod 15, after it reachesa predetermined elevation, causes the boss 35,;on the stripper plate I2 to engage the cam 34 which operates through a suitable mechanical mechanism, illustrated by the dash-dot line I I, to move the trip valve 52 to connect the conduit 12 to the air pressure supply line 51. With the air valve 52 in this position, the air goes through the conduit 12 into the other end 33 of the valve positioner 62 to move the piston I5 back-to its original position and thus move the master control valve 50 to its first position.

With the master control valve 55 in its first position, the top of cylinder A is connected through conduit 6| to the air pressure supply line 51. At the same time, the top of the cylinder B and the bottom of the cylinder A are connected through their respective conduits and through the master control valve 55 to the exhaust port 60 to exhaust the pressure from those conduits. The air moving into the top of cylinder A cause the piston rod I5 to move downwardly or in the first direction to return the stripper plate I2 to its normal position. As the piston rod 15. moves in this first direction, the trip valve 52 isagain positioned to exhaust the conduit line I2 and the other end 33 of the valve positioner 62 through the trip valve 52 by means of its exhaust port Hi.

When the pressure in the cylinder'A is substantially equal to that in the air pressure supply line 51, the sequence relief valve 53 operates to permit air to travel through the conduit I6 and into the bottom of the cylinder B. This air, thus building up a pressure in the bottom of the cylinder B with the top of the cylinder exhausting through the control valve 59, moves the piston rod I4 in the second direction or upward to remove the finger rods II from the finger tubes ID of the glove machine. After the finger rods have moved in the second direction, theglo-ve I9 may preferred form with a certain degree of particu-- iai ity, it isunderstood that the present disclosure or the-preferred form has been made only by Way of. example and that numerous changes in the details of construction and the combination and arrangement of parts may -.be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
