'7 Claims. (01. 68-9) The present invention relates to clothes pressing machines, and particularly to power operated mechanism for applying final pressure to the goods being pressed. More specifically the invention pertains to a difiierential gear connection between a motor and a toggle mechanism, a safety device controllin this connection whereby the. application of final pressure is inhibited until such time as the movable press head is so closely spaced with respect to the press buck that the operator is unable to insert his hands or fingers between the cooperating presselements.
is, therefore, the principal object of this in"- vention to provide means for locking the differential when it desired to apply final pressure to the elementstogether with a cam which prevents actuation of the locking means untilthe press head has been lowered to a position immediately above the buck and in proximity thereto.
It is a further object of the invention to provide for automatic locking of the press head in its final pressure position to permit application of heavy pressure for as long a period as desired and means for thereafter releasing the locking mechanism to allow the head to be elevated.
Another object of the invention is .to permit preliminary lowering of the head by the power mechanism, this. preliminary movement being limited, however, by other cam means which pro-- vents final application of pressure except by the means specifically provided for this purpose.
Still another object of the invention is to pro vide means for releasing the differential lock if, for any reason, the lock should be thrown into engagement with the differential except by the operator-operated means for actuating the lock.
Other details and their functions will be understood from the following description from which the operation and relation of the main features of the invention will be apparent.
In the drawings there is illustrated a preferred embodiment of the pressing ma'chinein which the several mechanisms included in the invention are incorporated.

Fig. 11 is a perspective view, of brake operating means employed in the actuation of the power means during preliminary lowering of the press head.
Referring to the drawings, the press comprises the usual base frame having an. extension 21 thereabove to which is fulcrumed the press head lever 22 carrying the movablev press element or head .23. A stationary press ele-- ment or buck 24 is secured to the frame above the table 25. The press is closed by the usual toggle mechanism comprising links 26, 27 piv oted to each other at 28. The link26 is connected to the lever 22 through a bell crank 29,
the latter being pivoted to the press lever 22 at 31 and to an adjustable resilient connection 32 between the bell crank and the front of the press head lever. The link 2'7 is pivoted to the frame 20 at 33. Springs 34 and 35 are connected respectively to lever 22 and link 2'7; as well as to the frame 20 normally to maintain the toggle'broken and the lever 22 in its elevated position.v I
The power means for lowering the press head includes a motor 36, wormshaft 37, worm 38. and worm gear 39. The toggle is adapted to be connected to the motor through a link 4.-1 pivotally connected at one end to link 27 and at its other end to a-disc-42 keyed to shaft 43. Also keyed to shaft 43 is a spider a l carrying planetary pinions l5 Whichmesh' with the differential gears 46, 47, both of which are free to rotate on shaft 43. gear 39 and since the motor runs continuously gear 46 is also a continuously rotating element.
Gear 46 is secured to worm Keyed to a boss on gear 47 is a locking ring 48 having teeth 49 on its periphery. Adapted to cooperate with the toothed periphery of the locking ring is a chamfered bolt 51 which'is slidably mounted. in a cylindrical guide 52 in the gear housing 53. The m ans for moving the bolt will be described hereinafter. It, is a parent that if the bolt be elevated to disengage the toothed ring, the gear 47 and ring 48 will be rotated in a directioi opposite that of gear 46, the spider being re "'vely stationary due to the resistance of the toggle mechanism. When the bolt is lowered, however, ring 48 and gear 47 will be held againstrotatioh; at which time the spider 44, shaft 43 and disc 42 will be rotated. A 2 to 1 reduction between worm gear 39 and shaft 43 is thus effected, resulting in a very efficient utilization of the power input.
: obtained a lost motion connection between these depression so that the bolt 51 cannot lock toothed ring 48. Lever 69,,is also provided with 6 a substantially horizontal projection 81 having a stud 82 thereon and; between which and a lateral projection 88 on the bracket 72 there is interposed a spring '84. The purpose of this spring is to elevate the hand lever 69 when the operator releases the lever. Lugs 85, 86 on lever 69 are threaded to receive the adjusting screws 7'7 and 87, the former'of which determines the rocking movement of the lever 62 which coopercertain positions with respect to the axis of the disc. The greater portion of the outer cam surface is concentric with the axis of the disc, there being provided, however, two depressions 89, 9l'thereon, between which is a raised portion 92 in the form oi a tooth. The inner cam has a track 93in which the roller 64 is guided during the open or elevated position of the press head, the locking bolt 51 also being raised at this time. There is also an enlarged channel 94 disposed nearer the axis of the discto permit lever 62 to be rocked downwardly to lower the locking bolt. A depression 95 in the inner cam track is so spaced with reference to the connection of the link 41 with the disc 42 that lever 62 may be elevated to raise bolt 51 when the press head is in its lowermost or final pressure position. It is, therefore, obvious, that final pressure may be maintained for as long a period as desired,
since the toggle is straightened and the motor disconnected from the crank disc 42 when roller 64 rests'in depression 95. When it is desired to elevate the press head after application of final pressure, the hand lever is depressed whereupon the power mechanism is reengaged to rotate the crank disc and break the toggle.
In Fig. 2 the disc 42 is shown in the position it assumes when the press head has been lowered to within a short distance of the buck. The depression 91 in the outer cam surface underlies the roller 79 on lever 74 of the bolt lowering mechanism and permits actuation of this mechanism. It is also apparent thatwhen the parts are in the positions indicated in Fig.2 the operator may grasp handles provided on the press head to pat the goods lying on the buck preliminary to the" application of final pressure.v When the hand lever extension 73 is depressed the differential gear is locked to couple the disc 42 withthe'motor whereupon the disc is rotated in a direction indicated by the arrows in Fig. l andZ. As the toggle is straightened to apply final pressure, the tooth 92 on the outer cam engages roller 79, acting as a kicker to enable the operator to ascertain when final pressure has been applied. The lever ,73 is then raised by the cam action of tooth 92 against roller 79 whereupon the spring 63 which elevates lever 62 and roller 64 enters depression 95 to release the locking bolt. In the meantime the tooth 92-rides past roller '79 bringing this roller into alignment with depression 89 on the outer cam surface. The extension '73 can then be depressed to break the toggle and raise the press head.
The power mechanism may be utilized for lowering the press head to premilinary pressing cooperation with the buck. For this purpose there is provided a brake adapted to hold the gear 4'7 stationary with respect to the machine .frame. The brake comprises a brake shoe 96 having a brake lining 97 adapted to cooperate with a brake drum 98 bolted or otherwise secured to the toothed ring 48. The shoe 96 is provided with a pintle 99 slidably mounted in a guide 101 in the gear housing 53. Cooperating with a squared portion 102 andshoulder 103 on the pintle 99 is a forked arm 10 i fastened to shaft 105 mounted in a bearing 106 on the base frame of the machine. Also fastened to shaft 105 is an arm 10'? having an arcuate s1ot108 in its end. 'Integrally formed with the arm 107 on the boss 109 is an arm 111 forming with arm 10'] a bell cranklever. Arm 111is connected to a link 112, the other end of which is connected to a foot pedal 113 pivoted to .the frame of the machine at 114. 'A spring 115 interposed between the foot pedal and the base frame normally holds the foot pedal in elevated position, at which time the brake shoe is released. Depression of the foot pedal engages the brake shoe with the brake drum 08 thereby effecting rotation'of the disc 42. The toggle will then be straightened and the press head lowered.
In order that the press head may be brought into only preliminary pressing relation with the goods on the buck, means are provided for releasing the brake when the press head has been lowered a predetermined distance. These means comprise an arm 116, rotatable on shaft 105, having a roller 117 at lower end and a cam 118 on disc 42. Arm 11c has a pin 119 thereon cooperating with slot 108 and a lateral shoulder 120 adapted to abut an adjustable stud 121 threaded in a projection 122 on the arm 111. Cam 118 is so positioned with respect to the corn nection of the arm 41 with disc i2 that it strikes the roller 11'? when the head has been lowered to the position in which the hand lever '73 may be depressed. in other words, the initial outward movement of the arm 116 corresponds with the beginning of the application of final heavy pressure. When arm 116 is thrown outwardly by the cam 118, shaft 105 is rocked to release the brake from the brake drum and prevent further transmission of power from the motor to the disc 42. If it is desired to apply further power to the crank it is necessary to lock the differential by means of hand lever '73. In this manner power actuation of the press head is interrupted to prevent application of final heavy pressure by a movement of the foot pedal while the operator may have his hands on the buck. It is desirable that the operator have manual control over the press head lever during preliminary lowering of the lever and usually .its elevated position, the bolt may drop by gravity into engagement with the toothed ring 48. Under these conditions power would be applied to the press head. A safety device is, therefore, provided in the form of a flange 123 on the spider frame 124. It will be seen that the spider frame is made in two parts bolted together, one of these parts having the flange 123 thereon. The contour of this flange is shown in Figs. 5 and 6. The rise 125 of the cam corresponds to the open position of the press, while the low portion 126 of the cam corresponds to that phase of the operation of the machine wherein the locking of the ring 18 is effected by depression of the hand lever '73. It will be seen that if, for any reason, the bolt 51 should tend to drop by gravity at any time other than that during which it is supposed to be lowered by actuation of the hand control means, the high portion of the card which underlies the bolt will prevent it from dropping into the toothed periphery 49 of thering 48.
From the foregoing-description the operation and purposeof the several mechanisms will be apparent. application of, final pressure can be effected only when the press head has been lowered suifi ciently, either manually or by power, to prevent the operator from inserting his hands between the cooperating press elements. It will also be seen that the power means for lowering the press to. preliminary pressing relation with the buck is limited so that serious injury to the operator is obviated by releasing the power meanfor the interval "between the preliminary pressing and final application of heavy pressure; Accidental operation'of the power means by. any means other than the brake-operated means for power application or the hand actuation of the-differential loci: is prevented bythe cam which underlies the locking bolt.
While a specific form of the invention has been described, the arrangement of parts is subject to modification and it is, therefore, not in-.' tended to limit the invention to the embodiment herein illustrated and described. 1
