Application flied; July 2, 1924, Serial-No. 723,831, and in Germany July 12, 1923,
The present invention relates to multiple sole pressing machines, and more particularly to machines of this type which are employed for incorporating cemented soles in shoes by using pneumatic pads arranged on a rotatable carrier or table and operated sue-- cessively for pressing the soles to the shoes.
Heretofore it has been the practice with machines of this type to inflate one pad while another pad is emptying. As a result the time during which the pressure is exerted upon a sole is limited by or at least dependent upon the operation on another sole.
One of the objects of the present invention is to produce a inultiple'sole pressing machine with pneumatic pads in which the pads operate independently of each other. This object is accomplished by providing a stationary air supplying device which may be easily operatively connected with any one of the pads without afiecting the air-outlet valve of any other of the pads.
Other objects and features of the invention will be set forth in connection with the following description of the illustrated embodiment of the invention.
In the accompanying drawing the machine is shown in a side elevation, partly in section.
The table 1 of the press is rotatably mounted on the vertical shaft 2 fixed in the standard 3. Around on the table l are arranged the sole pressing and the last holding devices. For every shoe there are provided separate and identical pressing and holding means It therefore sutiices to describe the devices desi ned to operate upon a single shoe only.-
T3 the table 1 is fastened the van 4- adapted to accommodate the pneumatic pressing pad 5. The pad 5 communicates by a check valve (3 with the air inlet duct 7 leading to the spout 8 adjustably attached to the table 1. For the air outlet a separate valve 31 is provided.
A column 36 for supporting the cross-arm 35 is fastened in the eye 26 of the van 1. The cross-arm 35 slides with the sleeve 28 upon the column 86 and can be fastened at a suitable height by the set-screw 29.
A single air supplying device serves for successively inflating the pads This device is carried by the forked end of the sidearm 33 of the post 3 and consists of the member 11 showing the air channel 12 and the air pipe 32 attached thereto. A valve 13 may be operated by hand or by a pedal to v 1nterrupt or restore the communication between the channel 153 and the pipe The mouth or spout oi the channel 12 is formed by the rubber-washer 9 held in place by the cap 10. A spring 15 arranged on the member 11 between the adjustable bushing 14 and the collar 16 tends to keep the air feeding device in the position shown. But the member 11 can be moved inwardly by pushing down the treadle 23. The treadle 23 is connected by the rod 22 to the bell crank lever 19, 20 pivoted at 37 to the arm 83. The lever 19, 20 is held away from the member 11 by the compressed'spring 38 and is connected by the rod 34 to the valve 13 in such a manner as toopen it when the member 11 is pressed against the spout 8 of the air duct 7 by the arm 20 of the bell crank lever. The screw 21 may be adjusted for timing the movement of the member 11 with relation to the opening of the valve 13. The spout 8 and the member 11 are held in line by the locking bolt 2% carried by the short arm of the gravity lever 25.
The mode of operation is asfollows:
The table is turned as to bring the van t in front of the air feeding device. The table is locked in this position by the bolt 24. A lasted shoe is then placed with the stirrup 3O thereon upon the empty pad 5 and underneath the cross-arm 35. By pushing the treadle 23 down the member 11 is firmly pressed against the spout 8 of the air duct 7 and simultaneously the air valve 13 is opened. The air rushes into the pad 5. The inflated pad 5 presses the cemented sole against the margin of the lasted upper and the insole so that the sole conforms fully to the curvatures of the last-sole. By freeing the treadle the air-admission is interrupted and the member 11 is moved away from the spout 8. The bolt 24 may now be unlocked and the table turned to bring the next van or any other van 1 in front of the air supplying device. The pads 5 remain inflated until the cement becomes soles adhere firmly to the shoes. Finally the valves 31 are opened, the air escapes from the pads, which collapse and permit a ready removal of the finished shoes.
I claim 1. In a multiple sole pressing machine, the combination with a rotatable carrier having a plurality of inflatable pads thereon and means for holding lasted shoes on the pads in position to be united with the cemented soles by pneumatic pressure, a plurality of air inlet ducts onthe carrier each in communication with a pad, a stationary air supplying device outside the rotatable carrier, air controlling means in connection with the said air supplying device operable from without the carrier to afi'ordcommunication with the same at the will of the operator, and spring-controlled means to return the said air controlling means immediately after release. I
2. Ina multiple sole pressing machine, in combination a rotatable carrier having a plurality of inflatable pads thereon and each of said pads having an air inlet duct leading thereto, means for holding lasted shoes on the pads in position to be united with the cemented soles by air pressure, and air supply controlling means apart from and independent of the said carrier adapted for .movement toward the latter in communication with said ducts.
3. The combination, in a multiple sole pressing machine, of a rotatable carrler having a plurality of inflatable pads. thereon, means for holding lasted shoes on said pads in position to be united with cemented soles by pneumatic pressure, a plurality of air inlet ducts on said carriereach in communication with a pad, a stationary air supply ing device having an air duct movable toward and from said carrier for co-operation with. said inlet tubes to inflate the pads, spring-actuated means for holding said air duct normally out of inflating position, and
means adapted to act in oppos tion to said spring-actuated means for moving said air duct toward the carrier into positlon to discharge air into said inlet tubes in sequential order,
4. The combination, in a multiple sole pressing machine, of a rotatable carrier having a pluralit of inflatable pads thereon, means for hol ing lasted shoes on said pads in position to be united with cemented soles by pneumatic pressure, a plurality ofair inlet ducts on said carrier each in communication with a pad, a stationary air supply ing device having an air duct movable to ward and from said carrier for co-0peration withsaid inlet tubes to inflate the pads, spring-actuated means for holding said air duct normally out of inflating position, and means adapted to actl in opposition to said spring-actuated means for moving said air duct toward the carrier into position to discharge air into said inlet tubes in sequential order, together with separate and independ ent means for emptying the pads.
'5. In a multiple sole pressing machine,
the combination with a rotatable carrier having-a plurality of inflatable pads thereon and means for holdinglasted shoes on the pads in position to be united with the cemented soles by pneumatic pressure, a plurality of air inlet ducts on the carrier each in communication with a pad, a stationary air supplying device havlng an air duct movable toward and from the carrier for co-operation with said inlet tubes to inflate the pads, means for yieldingly holding said air duct normally in inoperative position, and manually operable means adapted to act in opposition to said holding means for moving said air duct into position to discharge air into said inlet tubes in sequential order;
said holding means being adapted to automatically return said air duct to normal position when released by said manually operable means.
In testimony whereof I have signed my name to this specification.
