on Glove turners. Ser. No.fl3,837., led January i One object is to provide a glove turning machine that .requires but little physical exertion onthe part of .the operator and that functions to turn one, two.. three or four fingers of a glove in a very short period vof time, with little friction and vno .damage to the ,glove fabric. A further object is` to provide a .glove turning machine of sturdy construction that is partially operated by foot power and compressed air but that with slight alteration may be operated by motor power land compressed air.4

A still further object` is to provide a rotary type glove turning machine wherein one, two or more glovesmay be applied to the machine before the turning ,operation is initiated and upon starting the machine the several gloves may be turned without delay.

More specifically the invention consists in certain novel features and parts .and combinations of the same as will be more fully hereinafter described and pointed out in the claims. One embodiment of the invention is set forth in the ac companying drawings that form a part of this disclosure and wherein similar reference characters `denote corresponding parts throughout the several views.

The reference numeral I denotes a table suppor-t for the machine proper to the bed-.of which a base 2 is secured that receives and operatively supports thepl-unger rod 3 that extends through the table and that at its upper end sadjustably received in the tubular gooseneck A and secured in position by. thelset screw 5 carried by the goosef neck `collar. 6 .formed with a flange-.1 forming an abutment for the upper .end of the `expansion coil springV 8 .arranged uponrod 3 and .at its ilower end abutting. a tubular upstanding portion Aof base 2. Adjustably .secured to said gooseneck by the screw .orboltf is the .head |10 that carries the adjustable and .removable prongs vl l, preferably four in number, arranged .in an arc and secured in adjusted. position by the set `screws I3.

Welded lto the -gooseneck `4 is the horizontal end lt of the `auxiliary plunger rod l5, the vertical portion i-of which extends through the vbase 2 and through the table and carries at its upper end the collar |16 adjustably `secured thereto by set screw l1 that serves Vas an abutment for the .upper end of spring i8 coiled about said rod and resting upon base 2. Arranged upon the said rod 3 :below the `table is the small expansion spacer spring |.9 abutting the table .and the adjustable collar 2li. also iupon said rod, said .collar carrying the angular guide arm `2l that `extends up through said table and base and maintains -said arm and goosenecktrue :and against rotation.

Fulcrumed to .the :base '2.2 `of ya bracket 23 securedv to the vfront .of the table l is the angular flever :24 having one bifurcated .end freely receiving said rod 3 ,at a point inshort spaced relation to said collar 20.,norn1ally, but for engagement by said collar as said rod moves downwardly to `move said .leyerV downwardly from full line to .dotted line position, Fig. l. lastV upon rod .3 is the .collar 25Min spaced `:relation to the .adjacent end of .said `lever .24 corresponding to that .o'f collar 2i) above `said lever @its normalposition.

'The lower .end .of 4lever :24 is ,formed with-a alledem 3 plurality of perforations 26 affording adjustable selective connection therewith by link 21 carrying in 32, said link pivotally connected by pin 53 to the pawl carrier 28 whose pawl operates the ratchet wheel 233 fast to the axis 29 operatively supported in said bracket 23, said axis being connected by the meshing bevel gears 33 to the vertical shaft 3! of the rotary carrier 36, said carrier being supported by said bracket 23 and said shaft 3l mounted for rotation in bearings in said bracket, A contractile coil spring 33 connects pin 53 to pin 34 carried by bracket 23, said pins in the normal position of the moving parts being disposed upon a common side of the shaft 3| with the pin 313 in a relatively elevational and forward position.

It will be noted that the rotary carrier is disposed in a position slightly forward of the bed of the table. Arranged upon said carrier in a circle concentric with shaft 3| are a plurality of upstanding linger tubes 35, open at their upper ends, each containing a iioating tubular plungerV 31 of materially lesser diameter than said linger tubes and having fast upon its topmost end a head d@ of greater diameter than the plunger tube but smaller than said linger tube so that in the retracted position kof said plunger said head may be snugly received within said linger tube; said head being formed with a cross recess 38, the bore of said plunger continuing through said head and opening into said cross recess. The linger tubes are formed interiorly with longitudinally extending recesses 60.

The said recesses 60 form air passageways about the head l0 in its retracted position and about a guide block 33 freely received upon said plunger within said linger tube, said guide block being formed exteriorly with a plurality of vertical recesses lll, preferably four in number, as air and dust passageways and with small oppositely disposed recessed areas 45, Q into which the ends of the headless set screws d1, 48, removably carried by the linger tube, extend to anchor said guide block. A guide wire 49 secured at one end to the plunger tube contiguous to head 43 extends downwardly passing through guide block 39 to the enlarged base 5i), also vertically recessed, of Said plunger to prevent plunger rotation. A guide rod 5i secured to the inner end of the linger tube extends upwardly centrally through said plunger and carries thereabout an expansion coil spring 52 receiving the base end of said full floating plunger; said linger tube being formed at its lower end with an air vent perforation 90.

The said linger tubes are preferably arranged in live groups, each group comprising four tubes, a compressedair conduit 152 communicating with each tube of a group and having an air port d3 provided with an air valve operating to admit compresssed air from an air hose, air pump or the like. lThe extent of the arc in which a group of linger tubes is arranged corresponds exactly to that in which the prongs l i of head I3 are arranged and in the stationary position of carrier 35 one group of finger tubes is always disposed immediately beneath and in line with said prongs H. Since there are twenty linger tubes in all arranged upon the carrier said tubes will be eighteen degrees apart and the aforesaid prongs Il will be correspondingly arranged and spaced.

Referring now to Figs. l to 5 inclusive a foot pedal and compressed air operated structure is disclosed, the lower end of the plunger rod 3 having fast thereupon a collar 54 connected by linkage 55 to the foot pedal 56 hinged at 51 to the i table. In useJ one or two operators may attend the machine. If two are employed, one operator may apply the glove ngers, the thumb excepted, to the tubes of a group.

In the instant machine the operator may apply ve gloves, one to each group before the machine is started by the second operator, or he may apply only one glove at a time and after same has been serviced apply a second glove; or if but one operator is employed he may apply and remove the goves and operate the machine. After one or more gloves have been applied, wrongside out, the glove lingers being pulled well down upon the linger tubes until the heads 40 enter the linger tips of the glove, the pedal, from"Fig. 1 position, is depressed. This pulls plunger rods 3, i5 downwardly, compressing their springs 3, i3 and causing prongs l l to depress the plungers 31 with their heads 3 completely within the linger tubes 35; During this downstroke of the plunger rods Y 3, i5 the guide arrn 2l prevents rotation or play of rod 3. It will be noted that the space between collar 20 and lever 24 is the same as that between prongs Il and heads 4B before the beginning of this stroke. This is so in order that collar 20 may contact lever 24 at the same time that said prongs il contact said heads.

Collar 20 will now depress lever 24 to dotted line position and this being the idle stroke of said lever it will, through link 21 and pin 53 move the pawl of pawl carrier 28 idly over the ratchet teeth until said link and pin move to dotted line position with said pin 53 now disposed upon the opposite side of the vertical center line of said ratchet with spring 33 now having its terminals disposed upon opposite sides of said center line. The engaged glove lingers are now completely reversed but still upon their finger tubes; the pedal 56 is now released to permit the springs 3, I 8 to return their respective plunger rods. When said rods have moved an initial distance from their lowermost positions corresponding to that existing normally between collar 2l) and lever 24, prongs l l will have moved upwardly correspondingly from their lowermost position inside finger tubes 35, collar 25 will encounter lever 24 and move same well toward its full line normal position, said lever at its bifurcated end being iinally spaced above collar 25 by the action of spring 33 and link 21.

As the foot pedal is released the operator manually applies his compressed air hose to the port 43 of the air tube 42 to admit air into the finger tubes of the group then cooperating with the prongs i l, this air passing about the plungers 31, some passing out the vent in the tube 35, some passing through the recesses 44 of base 56 and block 39 and about head 40 and against the glove fingers still disposed upon prongs H, this air pressure assisting in the upward movement of the rods 3, I5 and the removal of the glove from the finger tubes when they may be readily removed by the operator from their position upon the prongs I i A complete stroke of the plunger rods comprises the down and return strokes and while the return stroke would be effected by the stout plunger springs alone it is materially facilitated by the application of compressed air.

As the lever 2li was being returned to normal position by the collar 25, the link 21 was returning the pin 53 and connected end of spring 33 to normal position upon that side of the vertical center line of the ratchet common now to it and pin 34. Spring 33 will, together with link 21 and the lever 24, have moved the ratchet in a work,

.esagero determines the extent of movement of the carrier 3d, whether from group to group of nger tubes orf a lesser movement.. This movement will take place-immediately after the prongs ll have. beten raised clear of the finger tubes. The application oi?4 compressed air to the finger tubes while-,same contain theglove fingers and prongs l i materially assists, and under a predetermined air pressure completely effects, their removal from said tubes and facilitates the operation and speed of the machine.

Referring now to Figs. 6 to 9 inclusive, a motor drive is provided wherein the pedal 62 is hinged and connected by spring 63 to the motor stand 6d whereon is supported the motor 85, the drive shaft thereof being connected by belt B6 to the fiy wheel el having the shaft S8 supported in a bearing in the bracket 69, said shaft having thereon a conventional type of single stroke spring bolt clutch lli that when the pedal is slightly depressed will cause one-half revolution of said crankshaft to depress the plunger rods 3a, I 5a corresponding in all respects to the rods 3, I5 of Fig. l.

It is of course understood that various changes may be made in the general form and arrangement of parts described without departing from the invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alteration-s as rightly fall within the spirit and scope of the appended claims.
