CHARLES RIESENWEBER, OF ST. LOUIS, MISSOURI, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO UNIVERSAL IRONING MACHINE COMPANY, A CORPORATION OF MIS- sonar.

Application filed May 31, 1921.

To all whom it may concern:

Be 1t known that I, CHARLES RIESENWEBER, a cltizen of the United States of America,

and a resident of the city of St. Louis and,

State of Missouri, have invented certain new and useful Improvements in Ironing Ma chines, of which the following is a specification.

The primary object of this invention is to provide improvements in laundry working machinery and more particularly to the class of machines used for ironing garments and the like, and in which improved starting, stopping and braking mechanisms are provided.

Another object is in providing an improved safety reversing mechanism for safeguarding the hands of the operator against being fed between the ironing roller and ironing board so that the feeding direction of said roller and board will be quickly reversed when the guard of the safety reversing mechanism is engaged by a too forward projecting of the hands of the operator.

A further object is in providing an improved arrangement of parts relative to the ironing board and roller, when said parts are in a position for removing or placing the garment on or off the board, in which the operator can more readily carry on the work of removing or replacing of garments witliout danger of coming in contact with and being burnt by the ironing roller.

A still further object of the invention is to provide improved securing means for the "paddingof the ironing board and for drawing the padding material on the board and securing it in its drawn or stretched position on the board.

Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference being had to the accompanying drawings exemplifying the invention, and in which,

Figurel is a front'elevation of this improved ironing machine.

Fig. 11 is a fragmentary cross sectional view of the pad and its support taken on the line XI-XI of Figure 7.

Referring by numerals to the accompanying drawings, the frame 1 of the machine is comprised of side members 2 and 3, and connecting said side members are horizontally arranged cross members i. and 5, and supported by said side members 2 and 3 is a horizontally extending rock shaft 6, which is arranged on a plane beneath the cross member l, and rigidly secured on each end of said shaft, on the outside of said side members is a crank 7, and journaled in said cranks is a shaft 8 which is arranged parallel with the rock shaft 6, said shaft 8 having an upwardly extending throw arm 9 rigidly secured thereto and arranged intermediate of its ends, said throw arm 9 at its upper end being so formed as designated at 10 for the support of an ironing board 11.

Arranged above the ironing board 11 is a horizontally arranged ironing roller 12, said roller being rigidly secured to a shaft 13, said shaft adjacent each end being supported in bearings 14 and 15 which are respectively mounted on the side members 2 and 3. The roller 12 is of a hollow construction and has a series of gas burners 16 stationarily held therein, said burners receiving their fuel supply from a gas pipe 17 which is extended through the hollow end of the shaft 13.

Rigidly secured to the shaft 13 on the outside of the bearing 15 is a gear 18, said gear being in mesh with a spur gear 19 which is mounted on the stub shaft 20, said shaft being horizontally extended and supported from the side member 3, and in mesh with said spur gear 19 is a pinion 21 which is securely mounted to one end of a drive shaft 22, said shaft being horizontally 7 supported within the bearings 23 and 24 which are respectively supported from the side members 3 and 2, the end of said shaft 22 extending beyond the side member 2 bearing a pair of loose pulleys 25 and 26, and arranged between said pulleys is a drive ulley 27 which is rigidly secured to the drive shaft 22.

A reversing belt 28 operated from a power shaft, not shown, is adapted to normally engage the idle or loose pulley 26, and in engagement with said belt IS a belt shifter 29 which is borne by a horizontally extending rod 30, and for engagement with the loose pulley 25 is a forwardly driving belt 31 under the control of a belt shifter 32, which is secured to a horizontally extending rod 33, each of said rods and 33 being supported from arms 34 of a shifting inem ber 35, which is slidable on the drive shaft 22, and depending from said shifting member 35 is a finger 36, and secured to said member 35 beneath the shaft 22 is a link 37 which is secured at one end to an arm 38 of a bell crank 39 which is horizontally supported at 40 to the side member 2, and connected to the arm 41 of said bell crank is a link 42 which extends to the forward part of the machine, said link at its forwardly extending endbeing bent so as to form a guiding slot 43 for the reception of the upper end of a lever 44 which is provided with a hub 45, said hub being turnably mounted on the rock shaft 6, the lower end of said lever being secured at 46 to a treadle 47, said treadle also being supported on the rock shaft 6.

The forwardly extending end of the link 42 adjacent the slot 43 thereof is provided with a disengaging lever 48 which is pivotally mounted thereto intermediate of its ends at 49, the end 50 of said lever 48 being arranged above a pin 51 which is extended through the upper end of the lever 44 which is borne by the rock shaft 6, each extending end of said pin adapted to engage within a respective recess 52, said recesses being provided on the underside of the paralleling portions 53 of the link 42 which provides the guiding slot 43 of the lever 44, and secured to one of the portions 53 of the link 42 is a retractile coil spring 54 which is secured at its opposite end to the cross member 5.

Connected to the end 55 of the link is an upwardly extending rod 56, the upper end of said rod at 57 being connected to a lever 58 which is rigidly secured to a turnfrom the link 42 is a reversing member able bar 59, the ends of said bar being journaled at 60 in respective brackets 61, one of which is secured to each of the bearings 14 and 15. Adjustably depended from said bar 59 on each side of the ironing roller 12 is'a leg 62, and secured to the lower end of each of said legs is a U-shaped tripping member 63, the horizontal portion thereof being aranged in a plane above the ironing board 11.

Located on the drive shaft 22 intermediate of its ends is a pinion 64, and in mesh with the underside of said pinion is a gear segment 65, and for holding said segment in mesh with said pinion is an underslung boxing 66 which is supported from the shaft 22 by the pair of ears 67, and located in said boxing is a wearing plate 68 which is adjustable by the screws 69, said segment at its forward end being flexibly supported to the throw arm 9 of the ironing board 11 by the horizontally extending pin 70, and secured to said pin on one side of the said throw arm is a cam 71 having a forcing portion! 2, said cam at its opposite end being supported at 73 to the rear end of the segmental gear 65. Secured at one end to the pin of the throw arm 9 is a strap '14, said strap atiits opposite end being secured to the bolt 73 which is carried by the rear end of the segmental gear 65, and formed at the rear end of said strap adjaeent said bolt 73 is an angularly extending portion 75 bearing a compression spring 76, which is secured to said extending por tion by a slidable plunger 77, and in travelng alinement with said spring is a movable aw 78, which forms part of a brake 79, which is mounted over the shaft 22 adjacent the pinion 64, said jaw 78 being pivotally mounted at 80 to the stationarily held aw 81, which is supported from the arm-82 which is extended from the cross member 4 of the frame 1. Secured to one side of the throw arm 9 is a st "iking arm 83, and arranged in the path of travel of said arm and extended 84, and secured to the throw arm 9 beneath the pin 70 is a pin 85, and mounted at one end to said pin is a link 86, said link at its opposite and lower end being secured at 87 between a pair of parallelly extending links 0 a, said links at their opposite ends being secured at 89 to a brake beam 90, and can ried between said pair of links 88 at the ends thereof adjacent the pivot 87, is a stop pin 91. The brake beam 90 is pivotally secured at one end as designated at 92 to a horizontally arranged sill 93, which forms part of the side member 2, the opposite end of said brake beam being slida'bly supported on the horizontally arranged sill 94 of the side member 3, and connected to said slidablc end of said beam is a rod 95 which is slidable within a bearing 90, and adjustably mounted on said rod is a nut 97 hearing against a washer 08, and mounted on said rod between the bearing 96 and the washer 98 is a coil spring 99.

The crank 7 which is located adjacent the side. member 2 is provided with an up wardly extending portion 100, and secured to said portion is a vertically extending lever 101 which is held at its upper end within a. guiding member 102, and pivoted at 103 to said lever is an operating handle 10 1, said handle intermediate of its ends being pivoted to a link 105 which is secured at its opposite end to the side member 2, said handle 104 when operated, being adapted to elevate or lower the ironing board 11 relative to the ironing roller 12.

In carrying out the operation of this improved machine in mounting garments to be ironed upon the pad of the ironing board (which will hereinafter be described in detail) the handle 104 is engaged and pressed downwardly in which the opposite end of said handle, which is connected to the link 105, will be forced upwardly upon the pivot 108, thereby breaking the lock provided by the handle 10 1 and link 105 when said handle and link were arranged approximately parallel to one another, and the lever 101 will be moved rearwardly by 1 the rocking of the shaft 6 as the weight of the throw arm 0, which is carried by the shaft 8., forces the crank 7 downwardly thereby lowering the ironing board 11 from contact with the periphery of the ironing roller 12 so that the garments can be mounted on the ironing board.

The stopping position of the ironing board 11 is normally in the position shown in dotted lines in Fig. 2, and in this position the cut away portion 106 of the ironing roller 12 is above the ironing board. This cut away portion is for the purpose of providing access to the rear end 107 of the ironing board 11 so that the operator will be provided with ample room for placing and adjusting the garments over said rear end 10?- without coming in contact with the heated ironing roller 12.

After the garments have been properly adjusted on the ironing board 11, the handle 10% is engaged and elevated and the pivot 108, which secures the link 105 to said handle, will provide the fulcrum therefor so that said handle at its pivot 103 will forwardly move the lever 101 until said handle assumes an approximate straight or horizontal position with the link 105, and in which the pm 109 carried by the rearwardly ext-ending portion of said handle will engage with the link 105, thereby providing a lock between the handle 101 and link 105 so that the ironing board 11 which was raised by the cranks 7, during the return or forward movement of the lever 101, will. be held in its elevated position for engagement with the periphery of the ironing roller 12. For assisting the raising of the ironing board by the arm 10-t and levers 101and 105 pertaining thereto, a balancing spring 110 is provided beneath the cross member 4, and bears thcreagainst, the opposite end of said spring engaging a short lever 111 which is secured to the shaft 6, said spring assisting in rocking said shaft 0 during the elevating of the ironing board.

In operating the ironing board and roller relative to ironing a garment after it has been mounted on the board, the treadle 4:7 is engaged and depressed by the foot of the operator, and inasmuch as the lever 4a is secured to said treadlc, said lever will be moved towards the operator and on account of the pin 51 being engaged within the recesses 52 of the link e2, said link will be moved forwardly thereby exerting a pull on the arm 41 of the bell crank 39, in which the arm 38 of said bell crank will exert a pull on the link 37 which is secured to the shifting member 35, and move said member outwardly on the drive shaft 22, in which the rods 30 ant 33 carried thereby and bearing the belt Shifters 29 and "2 will respectively shift the power belts 28 and 31 outwardly, in which the belt 31 will be forced over onto the drive pulley 2? from the loose pulley and the reverse drive belt 28 moved farther over on its loose pulley 26. The shifting of the belt 31 onto the drive pulley 27 will cause the shaft 22, on which said pulley 27 is mounted, to revolve and the pinion 61 will impart motion to the segmental gear 65, and as said gear 65 is secured to the throw arm 9 of the ironing board 11 by the pin 70, the ironing board 11 will be moved rearwardlv, and at the same time the periphery of the ironing roller 12 will be moved in contact with the garment on said board by the gears 18 and 19, which are in mesh with each other and the pinion 21, which is mounted on the shaft 22, and in mesh with the gear 19.

As the throw arm 9 nears the end of its rearward stroke the striking arm 83 carried by said arm 9 will engage the reversing member 84: of the link 42 thereby shifting said link rearwardly, in which the bell crank 39 connected thereto will be returned to the position from which it was moved by the forward travel of said link, and the shifting member 35 will be moved inwardly along the shaft 22, and the finger of said member will engage against the dwell portion 112. As the member 35 was moved inwardly, the rods 30 and 33 of the arms 34: of said member bearing the belt shifters 29 and 32 respectively will move be driving belt 31 from the drive pulley 27 on the loose direction, and, incid'ently, the pinion 6 1 will operate to return the sear segment 65 and the throw arm 9 ope "ated thereoy,

During the return travel of the throw arm 9, as said throw arm nears the end of its stroke, the finger 36 of the shifting member 35 will be engaged by the inclined or forcing portion 72 of the cam 71, and said member will be moved outwardly a distance thereby until said finger engages the portion 113 of the cam, said movement to said member 35 being great enough to cause the rod 30 to shift the reversing belt 28 onto the loose pulley 26, and in which the belt 31 will merely be moved to one side of the loose pulley with which it is engaged, the distance of the movement of said member caused by the inclined portion 72 not being great enough to carry the belt 31 onto the drive pulley 27, the travel of the throw arm being then completed by the momentum thereof as there is no power on the drive shaft 22, and onv account of said return movement of the throw arm 9 bearing the ironing board 11, completing the cycle of operation in which the throw arm is to be stopped, improved braking means are provided for resisting the momentum: of the parts in operation after the reversing belt 28 has been shifted from the drive pulley 27. This improved braking means consists of two sets of mechanisms, one of which is adapted to operate on the shaft 22 vand the other to operate on the throw arm 9, the braking mechanism for the shaft 22 comprising the brake 79' having the movable jaw 78, the lower end of said jaw 78 beingengaged by the spring 7 6 which is carried by the gear segment 65, said jaw being forced againstthe shaft 22 on its pivot 80, said spring engaging said jaw as the throw arm 9 nears the end of its return stroke, the braking mechanism which is related to the throw arm 9 being comprised of the links 88 which are connected at one end to the brake beam 90, and also to the link 86, said link 86 being connected to said throw arm so that when said throw arm nears the end of its rearward travel, the links 86 and 88 will tend to assume positions of longitudinal alinement with each other thereby creatii'ig a pull on the brake beam 90, which will resiliently yield on account of its co-operation with the compression spring 99, as shown in Fig. 2, said straightening out operation of the links 86 and 88 becoming more effective towards retarding the returning throw movement of said throw arm 9, and when the stop pin 91 of the links 88 engages with the link 86, the limit of movement of links relative to one another is completed, in which a resilient holding force will stop the return throw movement of the throw arm 9, the braking movements relative to the shaft 22 and the throw arm S) operating simultaneously.

So that the operators hands will be prevented from being drawn or fed between the peripheral surfaces of the ironing roller 12 and ironing board 11, means are provided for reversing the feeding direction of said roller and board whenthe operators hands get into a dangerous position. his improved reversing means is comprised of the lever 18, upwardly extending rod 56, lever 58, turnable bar 59, legs 62 and the U-shaped tripping member 68, which is arranged in front of the ironing roller 12, adjacent the ironing board 11, said parts just mentioned icing co-operable with the link 12 which con nects with the bell crank 39, and in opera tion, assuming that the ironing board is traveling rearwardly, and the operator is straightening the garment, the hand of the operator is extent ed to a position near the roller 12 wherein it will be engaged against the tripping member 63, the legs 62 will be swung towards the shaft 13 of the roller thereby rocking the bar 59 and elevating the end of the lever 58, which is secured at 57 to the rod 56, said rod upon being moved upwardly will swing the lever 48 which is pivoted intermediate of its ends at 19- to the link 42, the end 50 of said lever 48 being forced downwardly against the pin 51 which is borne by the treadle lever 4: 1, said lever 48 on account of being pivoted to the link 42 elevating said link 42 so that the recesses 52, which are formed in said link l2 reception of the ends of the pin 51, will be elevated from said pin thereby releasing said link e2 so that the spring 5% will become effective on said link 4 and move it rearwardly thereby actuating the bell crank 39, and on account of the link 8? connecting said bell crank to the shifting member 85, the belt shifter 32 will shift the driving belt 31 from the drive pulley 27 to the loose pulley 25 and simultaneously therewith the reversbelt will be shifted from the loose belt 26 to said drive pulley 2?, thereby immeditely reversing the direction of travel of the ironing board 11 and roller 12, so that the direction of feed is outward from beneath the periphery of the roller 12, and in which the operators hand is, therefore, prevented from being fed inbetween the periphery of the roller 12 and the ironing board 11.

Eigures (3, T, 8 and 9 of the drawings disclose an improved arrangement for securing the pad 11a of the ironing board 11, there being a pan 115 mounted on the upper surface of said board by bolts 116, in which a pad layer 117' is mounted within the pan and a facing or surface cloth 118 is adapted to be mount-- for the ed over the padding layer 117, in which the ends 119 of said cloth will bedepended over the upwardly extending edge annular 120 of the pan 115, and drawn beneath the ironing board and engaged'on pins 121, which are depended from the bottom of the pan 115 Within respective recesses 122, provided in the side and end edges of the ironing board 11. Secured to the underside of one end of the ironing board 11 are a pair of horizontally extending portions 123, each being provided with an eye 124, each of said eyes adapted tobe engaged by a finger 125, there being a pair of said fingers secured to one end of a clamping band 126 which is mounted over the edges of the ironing board 11 and the surrounding edge 120 of the pan 115, the manner of mounting said clamping band being to tilt said band so that the fingers 125 thereofcan each be engaged in their respective eyes 124 of the portions 123, see Fig.9; the end 127 of said band then being lowered, and inasmuch as said band conforms in shape to the edges of the ironing board 11 and the pan 115, the interior surface of said band will engage the depending edge 119 of the cloth 118 thereby drawing said cloth taut over the padding layer 117, and for securing the end 127 of said band in position is a catching member 128, which is secured to one end of a leaf spring 129, said leaf spring at one end being secured to the upper portion of the throw arm 9 of the ironing board 11.

For sustaining the side portion of the band 126 in position relative to the ironing board so that said portions cannot be sprung or forced outwardly therefrom upwardly extending brackets 130 are secured to the underside of the ironing board 11.

Secured to the throw arm 9, beneath the ironing board 11, is a catch pan 131 for catching and supporting the depending or trailing ends of the garments.

A coil spring 132 is secured to the lever a4 adjacent its upper end, said spring being for the purpose of drawing said lever rearwardly so that the ends of the pin 51 carried thereby can be reengaged into the respective recesses 52 of the link 42after said link has been automatically moved rearwardly by the emergency tripping of the U-shaped member 63 of the turnable bar 59.
