Application filed September 24, 1925. Serial No. 58,434fi The present invention relates to ironing -machines and an object thereof is to provide an ironing machine in which an ironing bed or roller and an iron are both operated through a motor and the connection between the motor and the bed is broken when the iron is positioned out of cooperative engagement with the bed. Anotherobject of the invention is to provide a construction- 0 in which the iron and the bed are both operated through a motor, and a shiftable gear in the driving connection between the bed and the motor is thrown through 'a motor driven cam out of mesh with a motor driven gear when the iron is out of cooperative engagement with the bed. Another object of the invention is to provide a bed and an iron both operated by a motor, the bed being free from the motor when the iron is out of cooperative engagement therewith. Still another object of the invention is to provide a construction in which a rotary bed begins to turn after an iron has come into engagement with the goods thereon but before final pressure between the iron and the bed is established so that the ironing of the goods is insured and, at the same time, the shock to the machine through the iron acting as a brake to the turning of the bed is eliminated. Another and still further object of the invention is .to provide an ironing machine in which the bed and the non are both moved through a motor and provision is made for permitting the iron to be operated ating the bed, so that the machine can be used for pressing goods as distinguished from ironing them. A still further object of the invention is to provide a machine which is speedier in action and simpler and less noisy in operation, and which also has a minimum number of parts. Still another and furtherobje'ct of the invention is to provide a machine in which the operating mechanism is readily accessible without dismantling the-machine. I

To these and other ends, the invention consists of certain arts and combinations of parts, all of wh ch will be hereinafter from the motor without oper 1 described: the novel features being pointed out in the appended claims.

Referring to the illustrated embodiment of the invention, 1 indicates a table having no supports 2 and provided at one end vwith a standard 3 .and at the opposite end with a goose neck standard 4. These two standards in this instance support ashaft 5 of a padded bed or roll 6, the goose neck standard 4 permitting the tubular goods to be amedv freely over one end of-the bed or rol er.

For cooperation w'rththis bed or roller,

/ 6 7 showing 7 ,there is provided an iron comprising, in this instance, an ironing surface 7 with a heating chamber 8 in rear thereof. This 1ron. has

arms 9 extending downwardly therefrom and pivoted at 10 substantially in a'vertical line with the axis of the shaft 5 with the ironing bed. The ironing surface 7 is curved to conform to the bed and the weight of the iron as a whole is such that it tends to move under gravity away from the bed.

The iron is heated, in this instance, by a pipe burner '11 which preferably is mounted to turn on the iron in rearof the heating surface 7, in order that the jet openings 12 may be thrown to play the flame on the rear surface of the iron when the latter is in cooperation with the rotary bed or away from such surface when the iron is moved away from the bed.

In this instance, the movement of the iron and of the burner is effected through a common means comprising two links 13 rigidly connected to the tubular burner 11 and pivoted at 14 to yokes 16 which are yielding ly and adjustably mounted .on the frame of the machine. In this instance, each of these yokes has a bolt 17- adjustable therein at 18 and guided longitudinally in the frame, the heads of the bolts 19 lying exposed for adjustment at the frontof the machine. These bolts are surrounded by helicalsprings 20 end of this link being pivoted at through a double arm lever 26. This double arm lever is in turn pivoted at 27 to a bifurcated swinging member 28 which is pivoted at 29 to the frame of the machine' Normally the swinging member 28 is held in the position shown in Fig. 6 by a detent 30 pivoted at 31 on the side frame 3 and adapted to enter a notch or recess 32 in the side of the swinging member, one end of this detent being extended at 33 to provide a handle by which the detent may be manually moved to hold the swinging member in the position shown in Fig. 6 or to permit this swinging member to shift the pivotal axis 27 of the double arm lever 26 to the position shown in. Figs. 7 and 8. This double arm lever 26 carries at the end opposite the pivot 25 a roller 34 which cooperates with a cam 35 mounted on the side frame 3. This cam 35 is so formed orshaped that it gradually causes the iron to a proach the bed or roller and to drop quic 1y away from the bed or roller. The

facilitated due to the fact that the cam com presses the spring 20 when moving the iron toward the bed and the expansion of this spring occurs on the movement of the iron away from the bed. At the same time the spring acts to cushion the iron at the end of the downward movement of such iron.

the end frame 3, and is also journalled in a cover member 38 which is secured over the cam to the inner face of the side frame 3 by bolts 39. This casing 38 also has bearings 40 and 41, respectively, for the pivot 29 of the swinging member 28' and the pivot 31 of the detent 30.

,In order to drive the ironing roll and at the same time to operate the iron toward and from the bed or roller 6, a motor 42 is secured to a laterally extending bracket arm 43 on a two part housing 44, which is bolted to the side frame 3. This housing 44 has a shaft 45 journalled therein, such shaft carrying a worm wheel 46 which meshes with a worm-47 on a motor shaft 48. Also mounted on the shaft .45 is a member 49 which has gear teeth 50 providing a gear for driving the roller or bed 6 as Wlll be hereinafter de-- scribed and which also has a. hub 51 projectlng therefrom and adapted to enter the pocket 52 formed in a casting 53 secured to the shaft 37' on the outside of the side frame 3. This casting 53 abuts a washer 54 about the shaft and the washer lies against a boss 55 on the frame 3 about the shaft 37. The

members 53 and 49 act as clutch members for establishing driving connection between the shaft 45 and the shaft 37. The member 49 to this end has an annular series of pockets or openings 56 and the member 53 carries the movable clutch part 57 in the form of a plunger guided in the part 53 and adapted to enter any one of the pockets 56 in order to connect the shaft 37 with the shaft 45. Control of the clutch part 57 may be effected by a yoke 58 pivoted at 59 to the clutch part and at 60 to the hub of the cast ing 53. This yoke is moved in one direction by a spring 61 and in the other direction through a means which cooperates with a movement away from the bed or' roller is yjBCtiODS engages the cam 62, the driving con- These parts nection between the shaft 37 and the shaft will be broken to permit the iron t6 lie in a position away from the bed, while, when the other projection engages the cam 62, the

clutch plunger will be operated to break the connection between the, shaft 37 and the shaft 45 to permitthe iron to lie in cooperative engagement with 63 is, in this instance, pivoted at its upper end at 66 to an arm 67 so that the member is loosely suspended from the arm. This arm 67 is in turn pivoted at 68 and is connected to a finger bar 69 arranged in the recess 70 formed in the table over which the clothes are passed to the bed 6 in order to be carried in cont-act with the iron Normally, the finger bar is held in a raised position-through spring means 71' and holds the projections 64 and 65 in the path-of the cam 62 but with the depression of said bar, the projections 64 and 65 move downwardly and the one in engagement with the cam frees the yoke lever 58 so that'the' plunger 57 will move into one of the pockets 56 and establish driving connection with the shaft 45. The finger bar being immediately released causes the other projection 64 or 65 to move into position to engage the cam 62 and break connection between the shaft 37 and the shaft 45 when the cam will have moved about 180.

the shaft 5 is a bifurcated or yoke member 73 which straddles the gear 72 and has a shaft 74 journalled thereon and carrying a small pinion 75 meshing with the gear, 72. are held to the shaft by the taper pin 72 which holds the gear 72. This shaft7 4 also carries a gear 7 6 which is adapt ed to mesh in turn with the gear on the casting 49 so that from the shaft 45 the ironing roller 6 may be turned. The teeth of the gears 50 and 76 are beveled o r backed off so that they tend to mesh when thrown one in engagement with the other.

It is desirable to stop the rotation of the bed or roller when the iron is'away from the bed, so that the goods will not be fed over the bed before" they are. ironed, This result of stopping the turning of the bed is secured in this instance by making the surface of the casting 5 3 in theform of a cam or eccentric,77 and engaging this cam by av roller 78 j ournalled on'the swinging yoke 73.

This cam 77 is so formed and timed that the iron contactswith the bed to engage the goods to be ironed before the bed begins to move; but before the final pressure of the v iron on the bed takes placegithe gear 7 6 is in driving relation with the gear 50 and the bed begins to turn. '{Ihis time of the commeneementof' the turning of the bed is important, as a shockon the motor does not take the bed. The memberOThis result, in this instance,

is securedby providing a latch or'detent 79 pivoted at 8 0 .to' the side frame and having a handle 81' 7 through which .the detent may be operated.

Normally this detent lies in the position shown in dotted lines in Fig. 4 out (if engagement with the swinging member 73, but, after the cam 79 has shifted the gear 76 out of mesh with the gear 50,'this detent may be moved to the position shown "in full lines in Fig. 4against .theabutment 82, so that upon the dropping of the swinging frame 73 by means of the cam 77, a shoulder or abut- 85 ment 83 on the swinging member 73 will engage the" detent 79. and, with the detent, hold the swinging frame in such apositiom that the gear 7 6 is not in mesh with the gear 50,and, as a consequence. the iron may be moved toward and from the bed to perform a pressing operation as distinguished from an ironing operation when the bed rotates.

The operation of the invention. "will be summarized as follows: 7

Assuming that the parts are in the positions shown in Fig. 6 and it is desired to start ironing,-the motor being running, the

throws the lug 64 out of engagement with the. cam 62 permitting the clutch part 57 .to move into engagement with the member 49, thus effecting driving connection between the shaft 45 and the shaft 37 turning the camfl3'5 to theposition shown in Fig. 5. Just before the final pressure of the iron 7 on the roll 6, the cam 77 lowers the gear 76 i into engagement with the gear 50, so that b no the gear 72 on the shaft'of the roll- 6 is established, causing the roll 6 to turn. This turning continues due to the fact that the cam 77 stops rotating after itis turned degrees, because the cam surface 62 engages with the camming projection 65 and shifts the clutch member 57 out of connection with themember 49. This also stops the action of the operating mechanism f the shoe including the ream 35 and the p rts operated thereby and the shoe maintains its position 2 against the roll or bed. When it is again desired to separate .the bed and the'shoe, the fingerbar 69 is again depressed, 'causin'gthc out of engagement with the camming surface 62, so that the clutch member 57 willjshift into engagement, with the member 49,:' thus again turning both the cams 35 and77, the cam 35"effe'cting the and the cam 77 causing the gear 76 to be The housing 44 with the shaft 45 and partsmounted thereon forms a separable driving unit which may be quickly removed to view or repair interior parts, and the hub 51 by entering the pocket 52 tends to align the parts quickly when the unit is fitted to the machine.
