IRONING-PBESS BURN GUARD.

Application filed February 6, 1925. Serial No. 7,238.

This invention relates to laundry ironing presses and the like and more particularly relates to improvements in burn guards for protecting the operator from being acci dentally burned by the hot exposed polished metal'face of the-ironing head or buck.

A further object of the invention is to produce an automatically operating burn guard in the form of a fiat member adapted to cover the not metal ironing surface of the machine when open and this device may assume the form of a roller curtain which is designed to be drawn across the face of the ironing member as the press opens up and which similarly moves back away from the face of the member to expose its polished ironing face directly to the work when the from between the closing-ironer jawsin or means such .as a pedal 13 pivoted at 14 in the frame havingan upstandin bell crank 55:. r toggle link 15. A toggle 16 is ironer closes down upon the goods.

Among other things, a purpose-of'this in vent-ion is to. produce an improved gear or chain driven automatic burn guard curtain for the purpose aforesaid but it is understood how certain changes may be made in construction and operation without depart tion of the ironing press in closed position showing the burn guard .member removed der that the work may be directl treated by the exposed metal ironing hea face.

' Figure 3 shows an underneath fragmentary view of the head looking up against the polished face thereof, and this view is taken on the line 3-3 of Figure 2.

Figures 4 and 5 illustrate an improved curtain operating means in the form of a chain suspended to engage the main drive pinion and take the place of the gear rack 23 hereinbefore described.

Referrin further to the drawings for a more detai ed description of the invention, there is shown an ironing machine frame with a press lever 11 pivoted thereon at'12 and provided with any suitable operating The buck is usuall or cloth 19 and I to cover and uncover the ex ose Figure 2 illustrates a detailed side eleva-.

ably connected tothe toggle link 15 and to the press lever 11 which enables the operator to close the ironing head 17 down upon the ironing buck 18 supported by the frame 10.

covered with a canvas or that reason the hot steam heated buck 18 is protected and will not accidentally burn the operators hand while spreading the work thereon, but the head 17 must necessarily carry an exposed as hotmetal ironing surface. 21 to impart a domestic finish and gloss to the work. My improved burn guard for ironing presses of conventional type just described may {be manufactured in the formof an attachmentm and installed on pressing machines in use, and this burn guard automaticall operates polished metal face 21 of the press cad 'inorder that it may effectively coo erate -witli the cloth covered ironing memher 18.' I By way of explaining the principle of my invention and. one form of structure thereof, there is shown a stationary gear rack 23 suitably anchored in this instance to the frame. One gear rack 23 is suificient though A two may be employed if desiredbyplajcing' one at each end of the

pressing members

17 and 18. A shaft 24 carries a drivcn gear 25 anchored to the shaft and'meshin with 5 the gear rack 23 which rotates the sai gear" 25. Each'end of'th e shaft-24 is fitted with a sprocket 26 anchored thereto.- A. support bracket 27 is fixed to each end of the ress head 17 and the aforesaid shaft 24 is ]0UI- ,90, naled in these two brackets 27 and the brackets serve to hold the shaftin proper osition with the One gear 25' in mesh with t e rack- 23 andso'it. follows that an \ip'and down motion of the head 17 subjects the gear 25 and the two sprockets26 to rotation; Front brackets 29 are fixed to each from corner end of'th'e press head-17 and these brackets journal a shaft 30. A sprocket wheel 31 is anchored to each, end of the loo shaft 30 and a suitable light weight chain 32 is carried on both sets of

sprocket I wheels

26 and 31 which provides two parala lel spaced chains 32.. This arrangement places a chain 32 at each end of the pressing ead 17 and this chain-serves to "draw a burn" guard back and forth across the head pressing face 21 and theguard may con-. sist of a roll-up curtain or otherfimeans.

One ofthe operating shaftsas -24- or 30 .v

is adapted to carry the aforesaid burn guard curtain and in this instance a curtain drum 34 is shown freely mounted on the front shaft and adapted to undergo slight rotary motion relatively to the shaft 30. Though this shaft is carried freely in the drum 34, a spring 38 encircles the shaft 30 and has one end thereof anchored to this shaft at 28 and the other end fixed to the drum at 22. Thus the shaft and drum are connected together by the spring only which acts something like a flexible key. The shaft, being the original driving member, drives the drum through the spring because the s rin is installed under a torsion strain sufficient to exercise a driving relation over the shaft.

The innermost end. of ,a curtain 35 is attached to the drum as is done with any ordinary roller curtain device. The outer free end of the curtain 35 is attached to a draw rod 36 which is preferably made somewhat longer than the width of the curtain. 35'so as to reach out beyond the brackets 29 and be attached as at 37 at each end thereof to the chains 32. It follows that the traveling motion of the chains 32 cause the curtain 35 to unroll from and roll back upon the curtain drum 34 and the spring 38 acts to kee the curtain tautly drawn. This improved construction in the spring connection existing between the shaft and drum removes strain from the spring which exists in ordinary curtain roller devices because the spring is notcalledsupon to Wind up the curtain'for the chains 32 perform both func tions, the rolling up and unrolling curtain action.

In operation, the ironing machine operator depresses the pedal 13 which brings the two ironing

jaws

17 and 18 together. This downward head movementinitiates counter clockwise rotation of the drive pinion 25. which causes the lower section of the chain 32 to move forwardly towards the operator thereby causing the burn guard curtain 35 to be wound upon the drum 34 by the pulling movement of the chain which uncovers the ironing surface 21 thereby permitting direct engagement of the bare metal ironing face 21 with the work upon the buck -18. After the ironing operation is completed theoperator may depress the kick-ofi pedal 40 which causes the toggle 1516 to bebroken rearwardly thereby allowing-the press head 17 to rise, the result of which is to reverse the direction of the chain 'movementthereby driving the curtain. 35 across the ironing face 21 to cover it up and protect the operators hand while the pressjaws are open.

his improved burn guard protectivev member shown in Figures 4 and 5 automaticallg moves across the ironing surface as t e n'omng head 51 rises and automatically moves back away therefrom as the ironer closes in order that the hot exposed ironing surface may directly engage the work and impart a gloss or domestic finish to the laundered goods.

scribed, the point of the difference being that I employ a flexible chain 53 which is passed oveia main drive pinion 54. The upper end of the chain is anchored at 55 to a frame bracket 56 and the other end of the chain is preferably connected; to a tension spring 57 which in turn is fastened to the frame at 58. i

The spring 57 serves to hold the chain 53 in positive engagement with the drive pin-- ion 54 in order thatthis pinion drive a shaft 60. A sprocket 61 is fixed to the shaft and a chain 62 is passed over the sprocket 61 as well as being passed over a sprocket 63 fixed to a shaft 64' and adapted to drive a curtain drum 65. A curtain 66 is rolled upon the drum with its outer edge fastened to the chain as at 67.

Thus in operating the last described formof the invention shown in Figures 4 and 5. it follows that an up anddown motion of the head 51 causes the drive pinion 54 to traverse the flexible suspended chain 53 which causes the curtain 66 to roll back away from and uncover the ironing surface 50 as the jaw 51 closes down on the work. Similarly, as the jaw opens, the drive pinion 54 acts to again draw the curtain 66 back across the ironing face to protect the operator from being burned while Working about the machine.
