PRESSING AND IRONING MACHIN 1E.

Application filed. July 1, 1926. Serial No. 119,886.

This invention relates to pressing and ironing machines such as are used in laundries, and particularly to the type of such machines wherein the pressing members are brought into engagement with the Work by hant, power means being subsequently applied during the actual pressing operation.

Generally, this invention embodies improvements over the pressing machines described in the co-pending application Serial No. 119,086 filed June 28, 1926, by Dana H. Benjamin and which on June 19, 1928 became Patent No. 1,674,274.

Specifically, the objects of my invention are to provide additional safety features in such a machine and means for increasing the speed of operation of the machine; and in eluding automatic latching means for holding the parts in full open position of the machine, starting means for the power motor semi-automatically actuated as the press is closed, and automatically timed mechanical braking means for positioning the press members in open or closed position.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

Fig. 1 is a side elevation of a pressing machine exemplifying my invention, the press being shown in full open position; Fig. 2 is a similar view of the machine in closed position with the pressure fully applied, parts being broken away to show construction; Fig. 3 is a similar detail section of the lower portion of the machine showing the parts in closed position of the press and before the pressing power is applied; Fig. 4: is a horizontal section on the 1; Fig. 5 is a horizontal section on the line 5-5, Fig. 1; Fig. 6 is a horizontal detail section taken in the plane of line 6, Fig. 1; F ig. 7 is a detail of the braking mechanism in the position appearing in Fig. 2; Fig. 8 is a detail section of the braking mechanism taken in the plane of line 8 of Figs. 2 and 7; Fig. 9' is a plan view of the balance weight; Fig. 10 is a section of the balance weight in line 10 of Fig. 9; Fig. 11 is a detail plan view of the machine showing the latching mechanism for the pressure arm and head; Fig. 12 is a detail section in the plane of line 12, of Fig. 11; Fig. 13 is a de-.

tail of the latching mechanism taken in the plane of line 13 of Fig. 11; Fig. 14 is a horizontal detail section of the latching mechplane line 44, Fig.

anism taken inthe 1 and 13.

Referring now to Fig. 1 the principal parts of the pressing machine are the base or frame 1 upon which is fixed the padded garment support or buck 2 and movably mounted the heated ironing member 5 adapted to co-operate with the buck 2 to press or iron articles placed between them. The ironing member is carried by an arm 4 pivoted at 4 upon the extension 1 of the frame of the machine, for movement to open or close the press.

Pivotedupon the arm 4 at the point 7 and adjustable with the arm by means of the handle 10 fast upon the screw 12 which extends through the threaded web 11 of the arm, is a member 7 provided with a depending arm as shown. Upon the rear end of the arm 4 is a weight 6. It will be seen that the arm 4 carrying the ironing member 5, the counter weight 6 and the member 7 form a unit movable about the pivot point 4 and balanced to seek the open position of the press.

A handle 13 is provided for convenient hand operation of this unit to close the press; and to thedepending arm of the member 7 is operatively secured power means for applying pressure to the ironing member in closed position of the press as will be described.

Upon the base of the press is a motor 14. connected through the coupler 17 to drive plane of line 14 of Figs.

through a gear reduction indicated generally by the rcference numeral 18 a shaft 19 on which is mounted a plate carrying the crank pin 20 which may beprovided with a roller as shown. Pivotally mounted at 21 is a pressure lever 22 the lower arm of which is provided with a slot in which the crank pin projects so that oscillation of thelever 22 would result from continuous rotation of shaft 19. To a laterally extending arm on the lever 22 at the point 23 is connected the link 24 which in turn is connected through the pair of links 25 to the member 7 at the point 9, the arrangement of the links 24 and 25 being obviously that of a toggle. Pivotally mounted at 27 is a hook shaped member 28 provided with a cam surface 29 adapted by suitable movement of the hook to engage an extension such as the roller 26 at the joint of the toggle referred to. A link 30 extending between the hook and the upper extremity. of the lever imparts motion to the hook upon movement of the lever, in a manner to be described.

What has thus far been described appears in the patentabove referred to.

The press is provided with suitable yielding and ajustable latch means adapted to normally and positively maintain the pressing head in open position, capable of actuation by a normal method of closing a press of this kind to release said latch and permit the head to descend to closed position. For this purpose the frame extension 1? has pivoted thereto a latch lever 36 provided with an abutment 36 and a limiting finger 36, said latch lever being yieldingly advanced toward latching position by a spring 37, and having one of its arms connected to a rod 38 extending to the front of the machine, where it has a fold or projection extending through a slot 39 in an arm pivotally mounted for actuation by the usual press closing handle 13. On the swinging arm 4 is mounted a stop member 34 adjustable by a screw 35, the stop 34 being adapted to wipe over the curved portion of the latch arm 35 and to also cooperate with the latch ing abutment 36.

Fig. 13 shows the parts in open press position, *ith the head latched up by the engagement of the abutment 34 beneath the abutment 36, finger 36 limiting latching movement of the arm 36 by its engagement with a side extension of the abutment 34. To close the press the hand is applied to the handle 13 with downward pressure, which turns latch 36 in the counterclockwise direction, Fig. 13, and releases or separates abutments 34, 3W, permitting the press head to be moved downwardly to closed position by continued downward pressure of the hand. As the head carrying arm 4 moves to open position the abutment 34 rides or wipes over the curved edge of the latch 36 until it reaches the position shown in Fig. 13, in latching engagement beneath the abutment 36. The lost motion resulting from the slot 39 in the handle is provided to make allowance for the varying angular relation between the parts.

Actuation of the motor 14 is initiated by the control handle 4.1 which controls the switch 32 through a bell crank lever 42 mounted upon the shaft 43, and the linkage illustrated. Mount-ed upon the shaft 19 is a timing switch 44 whereby actuation of the motor is interrupted upon movement of the crank pin 20 to the position shown in either Figs. 1 or 2-; with the parts shown in the position Fig. 1, movement of the control lever 41 upwards will thus effect movement of the crank pin in a clockwise direction, to the position shown in Fig. 2; and likewise return motion of the control lever 41 will return the crank pin in the-same direction,

which the crank pin link 30 owing to the lost motion to its originaliposition; this runaround motor drive arrangement being well known in this and many other arts.

It will be obvious that by the arrangement described movement of the control lever 41 will be immediately followed by corresponding movement of the ressure lever 22 to the corresponding position at one end of its throw.

In order to insure stopping of the lever 22 at the end of its throw I provide braking means as follows: Fixed upon the shaft 19 is a drum 45, which may be the disc upon 20 is mounted, and adjacent to which are mouted for co-operation therewith a pair of brake shoes 46 and 46; upon the lower extremity of the pressure lover I provide a projection 47 which is adapted to engage one of the brake actuating members 48 or 48 at the end of the lever stroke, to apply the bral'e and thus secure the shaft 19 and therefore the lever 22 in such position.

As the toggle moves from the position of Fig. 1 toward that of Fig. 3 movement of the hook member 28 is prevented by an arcuate finger 40 which may be integral with the hook as shown.

Secured upon the shaft 43 is an arm 49, its free end being secured, as shown, with the link 50. The link is provided at its opposite end with a slot through which passes a pin 51 secured in the hook member. By this arrangement when the parts are in the position shown in Fig. 1 movement of the control handle 41 to start the motor 14 is impossible. -When by closing the press the toggle attains the position shown in Fig. 3 however, upward motion of the control lever 41 to start the motor will cause through the linkage referred to, clockwise motion of shaft 43 and the arm 49, co-operating with the link 50, will force the hook to engagement with the extension 26 (Fig. 3) whereupon continued motion of the shaft 43 may initiate actuation of the motor. This mot-ion of the hook is independent of the connection shown between these two members.

As the motor causes rotation of the shaft 19 to move the crank pin from the position of Fig. 1 to that of Fig. 2 the pressure lever 22 is likewise moved from the position of Fig. 1 to that of Fig. 2. This causes through the link 30 movement of the hook to the position of Fig.2, which by means of the cam surface 29 straightens the toggle from its position of Fig, 3 to that of Fig. 2, to thus apply pressure to the member 7 to compress the article between the pressing members. This further motion of the hook is independent ofthe shaft 43 owing to the slot shown in the link 50. At the same time the pivot 23 is moved upward to produce further pressure, the arm of the lever Car between the points 21 and 23 forming a third toggle member, and with the link 24 a second toggle joint at 23.

After sufficient pressing time has elapsed the control lever 41 is returned to the position of Fig.1 causing in the manner described a return of the parts to their original position, the arm 4 returning to raised position as soon as the toggle is released by the hook, spring 52 acting upon fingers 53 projecting from the links 25 assisting in breaking the toggle in a manner which will be obvious.

In order to accelerate motion of the parts in operation of the press I provide a pair of springs 31 extending from the base of the press to the arm of the movable member whereby the pressing member 5 may be quickly raised to open position. A spring 32 connects with the hook to similarly return it to the position of Fig. 1; and a spring 33 is connected to the link 24 to cause the toggle to closely follow the closing motion of the press.

In actual operation of the press, after laying the article to be pressed upon the buck 2 the operator simply grasps the handle 13 and the control lever 41 and exerts pressure to move them together; the various parts of the mechanism functioning thereupon generally in the sequence in which they have been described.

To open the press however, it is merely necessary to lower the control lever to its original position.
