jflhisinvention relates to driers and particularly to curtain drie-rs,

The 'primary object of the invention isto `provide a drierhaving an article carrier so constructed that the article to be dried may be conveniently attached to and removed from the carrier `without danger of injury to the operator. It is also the purpose f o'f .the invention to provide a drier wlth the carrier uponV which articles may be placed or removed while others are drying.

The invention also contempla-tes the proi vision of means `for conveniently and ciently handling eurtains, the` illustrated embodiment of the invention `being Ashown as a curtain drier and to this end the invention consists in certain lnovel parts and-combinations of parts, all 'of which will be specifically destribed hereinafter, 'reference being `had to the accompanying drawings, 1n which Fig. lis a perspective' view ,of a drier constructed in `laccordan'ce withrny invention.`

` ig. 2 is a cross sectional view'through the drier casing, the carrier being shown in end elevation and the heating coil being shown in section. y i

Fig. 3 is a `perspective sectional view through the side 'bars of the adjustable frame.y i

Fig. 4 a `i!ragmentfarly `plan view of one of the side bars showing the detent `for holding the side bar in fixed position. Y 4ig. 5 is a perspective View of the stay braceff'or holding the curtain supporting bar `from sagging, and Y Fig. 6 is a cross sectional view through one of the bars of the curtain supporting frame.

The casing 1 of the drier consists of a substantially hollow rectangular structure having a. cover Q with a central opening` 3 there in, the edge of the opening being bounded by an opstanding inwardly directed iiange el which extends entirely around the four sides of the opening. In the bottoni ofthe casing is shown heatingcoil 5.` The heating coil may be of any appropriate construction so it is considered unnecessary to specificallyr describe it.

`l\ lounted, in end bearings 6 and 7 in the ends of the casing is a longitudinally disposed shaft 8 carrying a rectangular frame having three sides 9, 10 and 11 connected to the shaft by the

spider arms

12, 1S and 14. Each side is substantially the width of the opening 3 and .each side' carries a1 fabric supporting structure particularly adapted for supporting curtains. Each frame is a counterpart of ythe frames carried by thc other two `faces of the triangular carrier so it will `be necessary only to describe one of them. l

' Each frame Aconsists of two fixed end bars and `16, one (15) having a plurality of uplstanding pins 17 adapted toproject through the curtain @fabric to hold it to the frame, the other (161) being a uide `bar in the form of `a VFZI-bar to support t ie endsof the

adjustable side bars

18 and 19 which :like the bar 15 are provided with upstanding pins 20 and 21 Itopass through the curtain Vfabric to hold it on the frame. The lower ends of the bars 18 and 119 aresupported by the fiange 2Q carried by the bar 15. Therefore the bars `18 and 19 may slide toward and away one from the` other transversely across the carrier. r

In order that the

bars

18 and 19 may move in unison, I have provided two endless `

belts

23 and 24. The belt Q3 passes around pulleys 25 and 26. The belt `24: passes around pulleys` 27 and 28. The bai" 18 is fastened to the belts 23and Qd at 29 and 30. The bar 19 is fastened to thcbel'ts 23 and 2i at 31 and Therefore if one bar is moved away from the longitudinal center, the belts will inove theother bar a corresponding distance and vice versa. One of the bars is provided with a detent.

In Fig. 4 I have shown the bar 19 as carrying an elbow lever 33, one arm 34 of which is -pivoted to the bar at The other arm constitutes a grip or handle 36 whereby the elbow lever can be rocked about the pivot 85. The arm 34 of the elbow leveris connected to a spring actuated bolt- Bfby a. link 38 passing through guide 38 on the bar 19; `The spring bolt is of ordinary construction, the bolt having a shoulder against which one end of a spring `(not shown) bears, the other end bearing against the end of the barrel or sleeve 439. This spring bolt construction is well `known so it is deemed unnecessary to show it in detail or specifieally describe it.

O ad

the teeth of the rack -bar 40, then the

bars

18 and 19 can be spread apart to stretch the curtain after the curtain is fastened to the

bars

15, 18 and 19.

Then the

bars

18 and 19 are moved the proper distance apart, the operator will release the grip on the handle 36v and' allow the bolt 37 to engage the teeth so the bars will be held in proper adjusted position. On opposite sides of the frame are upstanding channel shaped walls 41, 42 having

perforations

43 and 44 to receive a transverse rod 45 adjustable longitudinally of the frame. The rod 45 has two constricted ends 46 and 47. The openings 44 are the size of the constricted end 47. The openings 43 are the size of the greatest diameter of the rod 45. There is al supplemental locking bar 48 in the channel of t-he'bar 41. It has perforations 50 vthe size of the constricted end 46. The locking bar 48 is normally urged against the web of the channel bar 41 by a spring 52 on the stud 58 carried by the lug 54. Therefore in order to insert the bar 45, the end 46 is passed through the perforations 43 and into the perforations 50, then the rod may be projected through the perforations 43 far enough to allow the constricted end 47 to engage one of the openings 44.

Upon releasingr pressure against the bar 48 the spring 52 will force the rod 45 longitudinally into the perforation 44 so that the parts assume the position shown in Fig. 3, then the rod 45 is held in proper position. The rod 45 is adjusted longitudinally of the frame to take care of curtains of different lengths, it being understood that the purpose of taking out the bar 45 is to permit it to pass through the hem at the top of the curtain after the manner of a curtain pole, so really the rod 45 constitutes a curtain pole or rod for supporting the upper end of the curtain, the lower end being fastened to the bar 15.

By adjusting the rod or pole 45 longitudinally of the frame, the curtain can be stretched to the desired amount and by adjusting the

bars

18 and 19 transversely of the frame, the crosswisc stretch on the eurtain can be effected. Obviously the longitudinal pull on the rod 45 would tend to sag it in the middle so in order to provide against sagging and in order to support the i' curtain at itslongitudinal center. I have provided a fixed longitudinal rod 55 carried by the ends of. the frame. On this rod is a sliding stay brace. It consists of an open link member 56 (see Fig. 5) carried by a plate 57 slidable on the rod 55.

The perforation 59 of the plate 57 is substantially equal to the diameter of the rod 55 so that a pull by the link 56 will cause theedge of the opening 59 to impinge upon the rod 55 and thereby prevent sliding of the plate. Therefore it will be observed that the stay brace can be adjusted longitudinally of the rod 55 so as to hold the middle part of the rod or pole 45 from sagging.

As above explained, each face of the triangular carrier, carries a counterpart of the structure shown at the top of the casing in Fig. 1, and inasmuch as it is desirable to hold the carrier rigid while the fabric is being attached to the frame presented to the operator or while the fabric is being detached, I have provided a detent or locking means comprising a vertically reciprocatory member 60 slidable in one end of the casing and normally urged upwardly by spring 61 attached to the member land to the end of the casing. The member has au offset finger 62 which may abut against one of the

faces

63, 64 or 65 of the bars 9, 10 and 11 as clearly seen in Fig. 1. The member may be moved out of engaging position by pressing down upon the end 66. It will be observed that the flange 4 fits relatively close to the carrier so that liability of the operators hand being caught when the carrier is rotated will be eliminated.

It will be observed that curtains on two sides of the carrier, for example 10 and 11 will be drying while the operator is removing or placing curtains upon the remaining face exposed to view. Therefore the heat will be evaporating the moisture upon two sides at all times. Consequently the capacity of the machine will be increased over that where a single frame is used and that in view of the construction shown, the operation of the machine can be practically continuous as it requires a very short time to dry the curtains in the casing as shown. By continuous of course I do not mean that the frame is continuously operated because obviously it must be intermittent for the purpose of putting on the curtains and taking them off' It will also be apparent that the curtains can be stretched in a convenient manner and expeditiously applied and detached from the carrier.

What I claim and desire to secure by Letters-Patent isz- 1. In a. drier comprising a casing, a carrier, and means on the casing for supporting the carrier. curtain frames supported by the carrier, each frame comprising fixed end bars having offset shelves, adjustable side bars slidable on said shelvesa curtain. rod parallel with said fixed end bars, means for adjustably supporting the curtain rod, and means for bracing the intermediate portion of the curtain rod comprising a longitudinal rod and an adjustable stay brace on the longitudinal rod for engaging the curtain rod.

Q. In a drier, a carrier, and curtain stretching means supported by the carrier including perforated rigid side bars, a supplemental spring-pressed bar adjacent one of the side bars and having perforations smaller than those of the adjacontrsido bar, 1L curtain rod having reduced ends oppositely receiv able respectively in ay side bar and `in said supplemental. spring-pressed bnr, the bar od jacent Said spring-pressed bar having en# izu'ged perforations to receive the body por# tion of said curtain rod for admission of tho reduced end of said rod to the spring-pressed bar whereby the spring-pressed bar may l latch the` curtain rod in position supported by said rigid side bars.
