Application filed July 17,

This invention relates to improvementsin ironing machines or garment presses.

The objects of this invention are to provide a machine of this class with power actuated relatively movable pressing members together with a guard for preventing accidental insertion of the operators hands be-- tween the pressing members, and means for preventing closing of the pressing members until the guard member is brought to closed position; to provide means in this type of machine for preventing application of power for closing the pressing members until the guard member is closed; to provide means for permitting opening'of the pressing members from fully closed position upon raising of the guard member; to provide means for preventing raising of the shield or guard until the press is fully closed; to provide means for setting in operation the press opening means upon raising the guard.

Another object of this invention is to provide a power press with a guard memher, means for automatically stopping the motor upon the members being completely closed and means under control of the opening of the guard memberfor opening the press and automatically stopping the motor when the press has been fully opened.

Another object of this invention'is to provide an electric control switch-in con-nectionwith the motor for closing and opening the press, together witha guard memher whose closing and opening movements control the actuation of the electric switch, said switch being capable of adjustment so as to obtain proper timed relation between the actuation of the motor and the closing and opening of the guard.

Other objects of the invention will appear from the following description and claims when considered together with the accompanying drawings.

Fig. 1 is a side elevation of our device with parts broken away and parts in section; Fig. 2 is a detail sectional view of the latch means for maintaining the guard in closed position until the press has been fully closed; Fig. 3 is a vertical section taken on line 33, of Fig.7, showing the open and closed positions of the guard; Fig. ,4 is a detail elevation of the control switch with its casing wall broken away; Fig. 5

-casing partly broken away; Fig. 9 is an elevation of the rotary timing switch with part of the wall broken away; Figs. 10, 11, 12 and 13 illustrate diagrammatically the electric control system of our device showing the several successive positions of the switches during the complete cycle of operation,'Fig. 10 indicating the circuit when the press is in fully openposition and the motor is idle,-Fig. 11 indicating the circuit during the closing operation,--Fig. 12

indicating the circuit when the press is in fully closed position and the motor is idle,- and Fig. 13 illustrating the circuit during the opening operation.

The lower pressing member or buck 1 is supported by the frame or pedestal 2 which is provided with the upwardly extending arm 3 upon which is pivoted the lever arm 4 at the point 5. The arm 4 carries at its forward end the upper pressing member or head 6 which is adapted to be lowered into pressing engagement with the buck 1.

The motor 7, which is suitably mounted upon a bracket on the machine frame drives through its rotor shaft 8 and the coupling 9 the worm section 10 which meshes with the ear irovided with a crank arm 13 which drives the connecting rod 1 1 pivoted at its other end at 15 to the joint of'the toggle mechanism 11 on 'the shaft 12. The shaft 12 is which is adapted to be straightened for closing the press. This toggle mechanism comprises'the lower link 16 pivoted in the frame at 17 and jointed at its other end to the clevis 18 which is connected to the rod 1.9. The adjusting nut 20 on rod 19 provides abutment for one end of the spring 21, the other end of which abuts the rear end portion of the lever arm 4:. Therod 19 extends upwardly through the rear end of the arm 4 by means of a T-shaped swivel member, the I two side arms of which are swivelled in the lever arm 4 whilethe main arm of the swivel has the rod 19- extending therethrough. The rod 19 is provided at its upper end with the cap 22. The swivel connection between the rod 19 and the lever arm 4 is already known in the art. Thus upon actuation of the motor, the toggle mechanism will be straightened through the connections just now described and the press will be closed; and upon again closing the circuit through the motor, the toggle mechanismwill be broken to open the press, these two positions of the toggle mechanism being indicated in Fig. 3 of the drawings. r

The guard member 23 is mounted upon the rearwardly extending arms 24 the rear ends of which are pivoted on-the axis 5 so as to permit the guard member 23 to occupy either raised or lowered position as represented in Fig. 3. One of the arms 24 extends rearwardly so as to provide the arm 25 carry ng the pin 26 which is adapted for cooperation with the slot 27 provided in the clevis 28 carried upon the upper end of the rod 29. The lower end of the rod 29 is connected to the clevis 30 which in turn is connected at its lower end to the slide rod 31 which extends through the housing 32 of the control switch mechanism. Suitably mounted within the housing 32 is the insulating block 33 having mounted thereon the contacts 34, 35 which have electric connection with the binding posts 36 and 37. Suitably mounted upon the insulating block 33 is the bracket 38 upon which is rockably mounted the arm 39 carrying the spring contacting blade 40 adapted for electric contact at its two ends with the contacts 34 and 35. The binding post 39 is also provided. The coil spring 41 insulated from arm 39 is connected at its one end to the arm 39 and at its other end to the slide rod 31 so that upon reciprocation of the rod 31 the contact blade 40 will be caused to snap into either of two positions, one of these positions being indicated in Fig. 4 and corresponding to the upper position of the slide rod 31. Upon lowering the rod 31 the contact blade 40 will be snapped into engagement with the contact 35. The binding posts 36 and 37 are wired to the contact segments 42 and 43 respectively by means of the binding posts 44'and 45, while binding post 39 is wired to the motor. These electric connections are clearly illustrated in Figs. 10 to 13.

Contact segments 42 and 43 are suitably mounted upon the insulating segments 46 and 47 which are in turn adjustably mounted within the casing 48. This adjustment consists of the screws 49 and 50 which extend through slots 51 and 52. The casing 48 is'in turn a'djustably mounted about the shaft 12 and is securel in adjusted position by means of the slotted ear 53 which is adapted to be clamped by means of a screw bolt extending therethrough and engaging the wall of the machine frame. The insulating collar or hub 54 is secured to the shaft 12 by means of set screws 55 and is provided with the contact ring 56 which has electric connection through thestrips 57 withthe bracket 58 upon which is rockably mounted electric contact shoe 59 held by means of the spring 60 in engagement with one of the contact segments 42 and 43. Suitably mounted on the inner wall of the casing 48 is the insulating block 61 having mounted thereon the bracket arm 62 upon which is rockably mounted thecontact 63 held by the spring 64 in contact with the ring 56. A binding post 65 for contact 63 is provided upon the bracket arm 62. It will be noted that the contact segments 42 and 43 are curved inwardly at one end so as to provide quick breaking of the circuit as the shoe 59 leaves one of the segments.

With the machine in open idle position as indicated in Fig. 1 and also by full lines in Fig. 3, the contact shoe 59 is in the position indicated in Fig. 10 and the control switch is in lower position as also indicated in Fig. 10, so that the circuit through the motor is broken. Then upon lowering the guard 23 to the dotted line position indicated in Fig. 3, the pin 26 will move to the upper end of the slot 27 and raise the rod 29 so as to move the control switch to the upper position or in other words to snap the contact spring blade 40 into the position indicated in Fig. 4, which corresponds to Fig. 11 of the drawings. The motor is then set into operation and will continue to operate so as to straighten the toggles and close the press head, at which point the traveling contact shoe 59 will leave the corresponding contact segment 42 and cause the circuit to be broken, the shoe 59 passing on to the contact segment 43 which as will be seen from Fig. 12 is not in the motor circuit. The press is then in fully closed position and will remain in such position until the motor is again energized, or in other words, until the contact segment 43 is placed in the motor circuit. This is accomplished by raising the guard which causes the contact blade 40 to close the circuit through the contact 35, as indicated in Fig. 13 of the drawings. The motor will then be set in operation to break the toggle and to open the press to the full line position, causing the contact shoe 59 to return to the segment 42, at which moment the circuit through the motor is broken since the segment 42 is in the motor circuit as illustrated in Fig. 10. Thus the cycle of operations is completed.

As a safeguard against raising the guard 23 until the press is fully closed we have provided the rearwardly extending rod 66 connected to the guard at 67 and extending through the swivel 68 which is moun.ed upon 125 the bracket 69 of the machine frame. The rear end of the rod 66 carries the nut or collar 70 providing abutment for thesprmg 71, the other end of which presses against the swivel 68. The swivel 68 is provided with an opening for the lock pin 72 which is adapted to engage in the notch 72 in the rod 66, so as tonormally maintain the guard in the raised position. The lock pin 72 is provided with the spring 72 and the screw plug 7 3 closes the opening for the same. As the guard is closed or lowered the rod 66 will be drawn through the swivel 68' which will rock upon its pivot and when fully closed or lowered the notch 74 in the lower side of the rod 66 will snap over the stud 75 provided upon the upper end of the thrust pin 76 which is mounted at its lower end in the trip lever 77. The rod 76 extends through the bracket 69 and is forced upwardly by the spring 78 and engagement of the stud 7 5 in the notch 74 will prevent raising of the guard until the press head has been fully closed, or until the projection 80 upon the arm 4 has been lowered so as to engage the trip lever 77 and thus Withdraw the stud 75 from engagement with the rod 66. v
