PRESSING MACHINE.
This invention relates to presses and especially garment pressing machines. More part-icularlythe invention relates to improvements in automatic press opening means.
An object of this invention is to produce an improved pressing machine having an automatic opening means or a trip means which causes the press to automatically open immediately following the release of the machine from high pressure.
In this class of garment pressing machinery it is usual to employ motive power to produce final high pressure subsequent to the closing of the press; and it is necessary to provide lockino' means to prevent an operator from releasing or opening the press `during the high compression period in order that the machine will not be damaged. It has been the practice to employ an operator operated device for opening the press immediately following the relief of high pressure, but in my improved pressing machine, there is provided automatically operated means for tripping the opening mechanism so that the press will open, in an automatic manner, immediately following the relief of the machine from high pressure, thus saving the operator the effort required in opening the press. s,
ln the accompanying drawings I have illustrated two practical embodiments of myinvention, but it is to be understood that I claim a right of protection as to all such changes as may come within the scope of my invention.
Figure 1 illustrates a typical garment press in side elevation with the improvements constituting my invention embodied therein. In this view the press is shown in high pressure position.
FigureQ is a similar view differing from Figure 1 in that the press is relieved from high compression, the position of the parts being such that the press` operating mech-.
anism is in the act of being released or kicked off to open up the press. Figure 3 is a sectional view taken on the line 3)-3 of Figure 2. Figure 4: is a fragmentary view 'of another form of my invention wherein automat-ic releasing means is combined with operator controlled releasing means; and Figure 5 is a sectional view on the line 5--5` of Figure 4 to show the relation of the release pedal with the closing pedal. l u A pressing machineconstructed in accordance 'with the plans of my invention has both an operator controlled and automatic press opening means. The automatic means is power driven or mechanically actuated and functions to open the press simultaneousl i with the release of the machine from high pressure so that attention and effort of thev operator is not required; and in addition to this automatic means, a kick-off device is employed whereby the operator, if he wishes, may open the press in case the automatic means for any reason fails to function or is not used.
The frame 6 of the pressing machine car-y ries the work support or buck 7 and a press lever 8 is fulcrumed at 9 on the frame. A press head 10 is carried on the front end of the press lever; and a toggle, consisting of pivoted links 11 and 12, is pivoted on the rear portion of the press lever yfor swinging the lever 8 to open and close the head 10 againstdown through a short movement to elevate and lower the vertical toggle 11-12.
A toggle comprising links 21 and 22 has its ends pivoted at 23 on the frame and at 24 on the vertical toggle. A pedal 25 is swung in the frame, and as shown in thedrawings,
is pivoted on the power shaft 17. A connecting rod 26 oins the pedal and horizontal toggle 21-22 in working relation. A coil spring Q17 has one end anchored to the frame and the other end anchored to the toggle for facilitating the lifting of the head 1() when the two toggles are broken.
Referring to Figure 4, a kick-off pedal 28 is pivoted in the frame on a pin 29, and this kiek-oft pedal has its rear end 30 sufficiently weighted to cause it to normally drop down against the floor or frame of the press, but
.for the purpose of this description it is shown held in horizontal position.
n The kick-off pedal has a projecting lug 31 which extends out under the lower edgey of the pedal 25 so that the lugstrikes the pedal causing it to move upwardly, thus breaking the horizontal.
the parts are show toggle 2l-22, which in turn collapses and draws inwardly on the toggle ll-l2 to rais the press head l0.
The cam tollower has an integral arm 35 projecting` upwardly and adapted to swing about the pin 16. il locking lever 36 is pivoted at 37 on the trame and has its upper end connected with the aforesaid arm 35 through a draw-rod 3S. The lower end oi the locking lever carries an adjustable screw or part 39 adapted to engage the rear end ot the kick-eti pedal 30 whereby this pedal is positively held against kick-oli movement during the time the press is under high compression, at which time the position ol" n in Figure el. rlh'is position of the lockingv lever relative to the kick-oliI pedal 23 is lnought about by the rearward swing,` ot tie arm 35 during the upward movement oit the cam 18 and cam vtollower l5 which draws tao rod 33 rearwardly and swings the locking lever part 39 into the path et the kickoff pedal 30.
As soon as the cam i3 is turned downwardly, the draw-rod 33 moves 'forwardly to swing the. locking lever 35 out or the path and away from the kick-olii pedal 23 so that an operator may depress the kick-oll pedal 23 producing an upward thrust on the pedal 25 to open the pressing` machine.
Describing` i'urther the .torni oit my invention shown in ldligure el, a release device 32 is pivotally carried on the pin Q3, and this device 32 has a lug` 33. A pawl i5 is pivoted on a pin 46 tothe pedal 25. This pawl is normally held in vertical position against a lug 4'? by a spring` 48. its the release device swings its lug downwardly, the lower end ot the pawl 4:5 pivots rearwardly to allow the lug,- 33 to pass, and immediately thereafter the pawl l5 springs back and stands in vertical position. A draw-rod 331L conneets the upper end et the locking lever 30 with the upper end ot the release devie 32 whereby the motion ot the locking` lever is transmitted to the release device. lln the operation of this particular form of the invention, the cam follower arm 35, during its rearward or lett-hand movement, pulls the rod 33a in the same direction to swing the lug 33 down` below the pawl or catch device and at this stage the machine under high compression. During` the nest cycle ol operation the cam 18 swings down and moves the draw- rods 33 and 33"l l'orwardly to drive the lug 33 up against the pawl 4&5 to quickly cause the press to open, and during` this movement it is noted that the lock part 39 moves away from the pedal 28 whereby the operator is :tree to depress the treadle 23 to open the press il' for any reason the automatic opening means 32 is not used.
Referring; now to the other ligures of the drawing, there is shown an automatic release lever l2 pivoted on a pin e3. The lower outer end of this release lever carries a iiXed lug or pin i4 which is in line with a pawl pivoted at 46a on the pedal 25, The pawl lo is held in normally vertical position against a. shoulder 47d through the agency ot a coil spring 48a. le lug 44; on the release lever `'freely passes the pawl l5 on its downward swingv because the spring yields and allows the lug` to tri p by until it assumes a position underneath the lower end of the nawl, as shown in Figure l. lilhen, however, lie release hui lll moves upwardly it impinges bottom end oi the pawl which causes the i edel 25 to be quickly driven upwardly, thus oreaking` the two toggles and opening the press. A drawe'od 49 connects the upper end et the release lever l2 with the arm 35 and is actuated by the cam follower l5 to swing' the release lug ill upwardly to open the press otter the cam is moved to its downturned position shown in Figure 2.
A garment press et this class is sometimes used without the motor, for the closing power olf the pedal 9.5 is substantially great, and produces pressure adequate for some classes ot work. lt is to be notedthereore, that on some occasions the machine would not be operated by power, and therefore the power release mechanism would not function. lhe kick-oil' pedal 23 is therefore provided for the purpose of opening the press by'footpower when the power means or electric motor drive is not employed.
The appartus comprising,v my invention is simple in construction and operation and provides a press with either a pedal opening means, or an automatic opening means, or a combination oiI both such means, and cilitates the work ot the pressing' machine.
