To all whom, it may concern:

Beit known that l, CLARENCE L. Coller, a citizen of the United States, residing in the city of Richmond, in the county of Wayne and State of Indiana, have invented new and useful Improvements in a Combined Door and Automatic Closing Means Therefor, of which the following is a com lete and exact exposition, suoli as will enab c others skilled in the art to which the invention relates to make and use the same, when taken in connection with the accompanying drawings.

' My present invention contemplates more particularly the combining of a doorof the character shown with independent and automatic means for closing the door under ex traordinary conditions, as in the event of ire, at the same time leaving the door free to be o erated at all times without interference of t e parts.

Another object is to provide a fire-door applicable to o enings leading into brick or otherI iireproo elevator-shafts and also being applicable as a freight-house or factory doorl Another object is to provide a door involving simplicity of construction, ease of operat on, requiring small space for its installation and operation, occupying only,T a space equal to the thickness ofthe door plus the track above the opening, and providing a doorand automatic operating means therefor which canbe made at a comparatively low price. 1

One manner of carrying out the objects of my invention is shown in the accompanying two sheets of drawings, in Which- Figure 1 shows an elevation ofxny invention with thedoor open and the automatic mechanism set ready for operation. Fi 2 is a detail Sectional view taken on the line X X of Fig. 1. l' Fig. 3 shows an elevation of my invention with the door closed and the automatic mechanism released and in the position in which it would be after having per formed its work. Fig. i is e detail front view of the releasin device. Fig. 5 is a detail side view of the re easing device, and Fig. 6 is a detailsectional View taken on line Y Y of `vertical side Wall B, the door-opening C, the

Hoor-line, and D the upper oists of the bniidglhe numeral 1 denotes my ire-door adapts ed to close the opening B. Extendin up vertically from the lloor (I to the top oipand on the right and leithand of the opening B and permanently secured to the face of the wall A are the channel- tracks 2 and 3, respeetively. Extending out horizontally arallel with the joist D and extending from t 1e level of the to s oftthe channel- tracks 2 and 3 and of a less istancc apart are the tracks 4 and 5, which are substantially of saine length as is the door 1. The inner ends of thc tracks 4 and 5 are secured to the wall A, and their outer ends are supported by one or more hangers 6 and 7, which are suspended from the joists l). The

-said tracks 4 and 5 are spaced spart and held in proper relationship with cach other by the rods 8 and 9.

`Mounted on the respective right and left upper corner portions of the fece of the door A1 are the vertical straps 10 and 11, which extend slightly above the upper edge of the door and are rovided with horizontal ivot openings in t ieir upper extension, as s iown, to receive the pivote bolts l2 and 13, respectively.

Monnted on the tracks 4 and 5 ere the rc- `spec-tive pairs of trucks 14 and i5, each heving its dependent hanger-bar 16 and .17, respectively, and the lower ends of said bars 16 and 17 are pivoted on the respective bolts 12 and 13, whereby the door 1 is suspended suhstantially as shown. Secured Khorizon tally to the lower right and left corners of the door 1 are the straps 18 and 19, respectively, which straps extend eronnd the door'the thickness thereof, which latter portions carry each an axle, on which axles are the respective rollers 20 and 21, said rollers being formed to neatly i'it the respective channel- tracks 2 and 3 in which they are adapted to travel, nach roller being rovidcd with a flange extending out around) from the inner edge of their oriphcries, shown most clearly in Fig. ti, W ereby the ends of the axles are prevented from contacting with their tracks. i

Mounted on the same axles with the rollers 20 and 21 between therollcr and the strap are the respective right and left links 22 and Secured in the upper ends of the respec Ytive links 22 and 23 are the ends of the re* spective cables or the like 24 and Upon the well A are permenently located the sheaves 26 and 27, over which extend the respective cables 24 and 25, as shown, and said cables then extend to and ere secured in IIO . door.

their respective counterbalance- weights 28 and 29 for the doors.

It is now apparent that the door being closed, as in Fig. 3, by ulling forward `onthe door its upper end wil be carried out on the tracks 4 and 5, while its lower end will be carried up in the tracks 2 and 3 until it shall have assumed the osition shown in Figs. 1 and 2, where it wi be retained by the said weights and will be entirely out o'r' the way.

For securing the door when closed a spring catch 3() .ma be used, as showiniwhich. is attached to t e upper central `portion of the Secured in the center ,of the face of the door is the ear 31, in which is pivoted one end of the spring-arm 32. When the arm 32 is not in use, it ma be folded flat against the door and retained Viiy the keeper 33 over the head of which .the arm passes, as shown. By means of said-arm the door may be ieasily opened andclosed manually and when closed is automatically secured by the catch 30.

I nowicome to the descriptionof the mechanism for automatically operating .the `door for fire purposes.

Secured to the wall A -slightlyto `the lett of the sheave 27 is a sheave 50, over which passes the cable `or the vlike 51. The numeral 52 denotes a screw-eye located inthe side of the weight 29, through which screweye extends one .end `of the cable 51, and secured to the cable 51 below'the screw-.eye 52 is the small weight 53.. The `opposite end'of the cable 51 is secured to the intermediate weight 54. Secured to the left of the sheave 50 on the wall A is one of the releasing devices shown in detail in Figs. 4 and 5 and which will be prese'ntly described in detail. To the left of said releasing device is a pair of loose pulleys 55 and 56, which are suspended from some stationary point, as the wall A.

The numeral 57 denotes a wire or the like, and numeral 58 denotes a wire orthe like, said wires being united by a fusible link, as is indicated.

The wire 58 extends thro h the pulley 56 and is then secured to the wei ht 59. A central longitudinal apertureis ormed through the weight 59, and through said aperture loosely extends the wire or `cord v60, which also Aextends through the pulley 55 and has one end secured to the upper end of the lever 67 of the releasing device, and on. the other end of the cord 6() is a small weight 61. Extending up from the weight 54 is a short cord 62, in the upper end oi" which is the ring 63, which ring is adapted to be placed over the hook 66 ol' the releasing device. Saidreleasing device consists ol' the body 64, having the arm pivoted vertically thereon, as shown, and on the lower ciid of the arni 65 near its pivotal point is the hook 66. Pivoted vertically near the center of the body 64 and then extending upward is the lever 67, in the upper end and near the conter of which are lon cated the eyes c and l), respectively. In the upper endof the bod 64 is a horizontal bar 68, behind which the ever 67 passes. On the upper end of the arm 65 is a catch 69 'for enga ement behind the lever 67, as shown.

he numeral 70 denotes a helical s ring secured at one end iii the eye b, with t e other end secured to some stationary point. The tension of the spring` 7U is such as t0 allow the lever 67 to be turned to the left to release the Weight 54 and after said weight is released to return said lever to the position shownn in the drawings.

This arrangement of sheaves, cable, and releasing device is du heated on the right of till; door, as indicate by the primed numera' Lt will now be seen that the door being up, or o en, as in Fig. l, the wire 57 bein exten ed to the desired point with fusible inks located at desired intervals, and the other parts being located substantially as shown in ig. 1 in case of the fusible links being dainaged by lire or otherwise, the wire 58 being freed, the weight 59 will be dro ped on the small weight 61, the Wire 60 willlpull the lever 67, and it in turn by the wire will pull i the lever 67 to the left, causing the arms 65 and 65 to drop forward, releasing the weights 54 and 54. The weight of the wei hts 54 and 54. will then be exerted to over alance the weight of the Weights 28 and 29, whereby their weight will be added to the weight of the door, resulting in the closing of the door automatically;

My invention is ositive in its operations and accomplishes t e objects above stated, and it is evident that changes therein may be made whereby to accommodate the invention to varying conditions without departing from the principles of the invention, and it is understood that various changes therein may be made as would suggest themselves to the ordinary mechanic.

Havingenow fully shown and described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. A counterbalanced door operative on a vertical and a horizontal track, in combination with sus endedauxiliary weights, and devices wherdb the auxiliary weights may be .released andy add their weight to that if the door to close it automatically, substantially as set forth.
