JAMES C. FERNALD, OF PHILADELPHIA, PENNSYLVANIA.

WEATHER-REPELLING DEVICE FOR DOORS.

SPECIFICATION forming part of Letters Patent No. 639,026, dated December 12, 1899.

Application filed December 10,1897. Serial No. 661,419. (No model.)

To @ZZ whom t may concern.'

Be it known that I, JAMEs C. FERNALD, of Philadelphia, State of Pennsylvania, have invented a new and useful device to be iuserted in a channel plowed in the bottom edge of hinged or sliding doors, whereby thev joint or aperture of whatever size beneath them is automatically closed upon shutting the door, and upon opening it the device is raised clear of the aperture, leaving the door free to pass over all obstacles in the path of its motion back and forth; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reterence being had to the accompanying drawings, making a part of this specication.

My invention has reference to weatherrepelling devices for doors and it consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide, the lower portion of a door with an adjustable and automatically operated weather strip which is positively depressed when the door is closed, so as to fit down upon the sill or floor, and automatically raised when the door is opened, so as to clear all obstructions or irregularities in the surface of the door.

My improvement has special advantage in such doors as those employed in re-engine houses, where the doors must have considerable clearance to tit over the tracks and also to permit the swinging of the doors where the floors are considerably inclined. By this improvement such doors are made perfectly weather-'tight when the door is closed and yet permit of a great deal of clearance when the doors are being opened.

In carrying out my invention I provide the door with a veriicallyfmovable carrier-frame furnished at the lower part with a rubber tloor-strip adapted to come in contact with the ioor. The weather strip and carrierframe are connected with a reciprocating bar by means of suitable pin-andslot connec tions or equivalent cam-actuating devices, whereby when the frame is reciprocated the weather-strip is raised or lowered according to the direction of movement of said bar. I

further employ a spring for automatically shifting the bar, so as to cause the Weather strip to be raised, and a stop, preferably adjustable, for moving the bar in the opposite direction against the action of the spring for the purpose of depressing the weather-strip when the door is closed. The reciprocating bar, spring, `carrier-frame, and Weather-strip are carried on the bottom of the door, and the adjustable stop is arranged in the doorframe.

My invention will be better understood by reference to the accompanying drawings, in whichM Figure l is a sectional elevation of my improvement with the door removed and showing the Weather-strip in its elevated position and just about to belowered. Fig. 2 isa crosssection of same on line :c oc, showing the Weather-strip devices applied to the door. Figs. 3 to 6 are elevations of portions of the apparatus, and Fig. 7 is a perspective 'view of my improvement with the weather-strip depressed.

The bottom of the door His grooved, as shown in Fig. 2, and arranged therein with provision for longitudinal movement is the reciprocating bar B, having at intervals the downwardly-extendin g wings b, provided with slotted o'r cam parts K.

The end of the bar B adjacent to the hinged part of the door is provided with a guide e, working in an end plate E, provided with a vertical slot I in its lower part. The said end plate E is properly secured to the lower inner edge of the door. The other end of the bar B has a tongue d formed thereon, and said tongue is inserted within a coil-springD,

which has its other end secured to or carried by the end plate F, itted to the outer and lower end of the door, saidplate being also provided at its bottom with a slot J. Spiked portions f may be employed to iit into the wood on the bottom of the door to more firmly hold the plates E and F from being shifted.

A is a U-shaped carrier-frame preferably formed of sheet metal and is guided between the end plates E F and adapted to move through the slots I J thereof. This U-shaped carrier-frame A is provided with transverse pins c, which are acted upon by the cam win gs or portions b, part or all of which may ICO , frame A.

have portions so as to form, in effect, slots K, into which the ends of the pins c extend.

The weather-strip proper is formed of rubber and may be made of the shape indicated at a, having the upper parts of its arms clamped in the lower part of the carrier- The weather-strip is thus preferably hollow, so as to be perfectly flexible, and thereby adapt itself to any irregularity orincline in the floor.

It will now be observed that if the bar B is shifted (from the left to the right in Fig. l) the carrier-frame A and the weather-strip will be depressed to the position indicated in Fig. 7. If, on the other hand, the bar B is released, the spring D, reacting, will shift the bar from the right to the left and raise the vweather-strip into the position shown in Fig.

l. The means for accomplishing` this result is the screw stop or abutment C, which is screwed into the frame of the door and in alinement with the guide e, so that when the door is closed the said guide strikes the end of the stop and causes the bar B to be shifted longitudinally against the action ofthe spring D. By adjusting the screw-stop C to the requisite depth in the frame agreat-er or less action upon the bar B may be secured, and in this manner the weather-strip may be depressed to a greater or less distance, as required. 'Ihe end of the screw-stop C is formed with a head by which to turn it for adjustment, and the end plate E has a recess into which the said head may be received when shifting the bar B by acting upon the end of the guide e thereof.

W'hile I prefer the construction shown, I do not limit myself to the minordetals thereof, as they may be modified without departing from the principles of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a weather-repelling device, the combination of a vertically-movable strip or clamp placed in the bottom of a door between two retaining-plates and heldin position by means of slotted clips, and a guiding strip or rod to which the clips are attached-one end of the rod or strip projecting through the retainingplate against a regulating-screw in its path; the other end jutting against and acting upon a spring held in position and attached to the opposite retaining-plate. j

2. In a weather-strip for doors the combination of a vertically-movable carrier-bar provided With laterally-extending projections and carrying at its bottom a strip of soft material, with a cam-frame longitudinally movable and provided with downwardly-extending parts forming Vertical guides between which the carrier-frame moves and provided with cam slots or surfaces foroperating upon the projections of said carrier-frame, a spring to move the cam-frame in one direction, and an abutment to move the cam-frame in the other direction.

3. In a weather-strip for doors the carrierframe made with downwardly-extendingjaws, combined with a rubber door-strip made U- shaped and having its center hollow its bottom grooved and its upper part clamped between the jaws of the carrier-frame so as to press the two opposite edges of the rubber together. j

4t. In a weather-strip for doors, the combination of a vertically-movable carrier-frame provided on the lower part with soft material, and at the top with laterally-extending pins or lugs, a longitudinally-reciprocable actuating frame or bar having oblique cams acting on the pins or lugs for moving said carrierfraine vertically, a spring to move the said cams and bar in one direction, and an adjustable stop attached to the door-frame acting as an abutment for shifting the said bar in the opposite direction.

5. In a weather-strip for doors, the combination of a vertically-movable carrier-frame provided on the lower part with soft material, end plates adapted to the door and acting as guides for the carrier-frame, alongitudinallyreciprocable Vactuating frame or bar having oblique cams for moving said carrier-frame vertically and also having an extended or exposed end extending through a hole in one of the end frames said hole being enlarged on the outer side to form a socket, a spring to move the said bar in one direction arranged between the other end i'rame and the actuating frame or bar, and an adjustable stop attached to the door-frame to act as an abutment against which the end of the bar works for shifting the said bar in the opposite direction and consisting of a screw having an enlarged head by which it is adapted to be rotated for adjustment and also adapted to be received into the socket in the end plate.

G. The combination of the two end plates E, F,a recprocable barBhaving downwardlyextending Wings b provided with oblique slots K, a carrier-frame A arranged between the wings and provided with transverse pins c working in the slots and a soft iioor-strip on the bottom, a spring D interposed between the end plate F and the end of the bar B and an abutment carried by the door-frame adapted to operate upon the other end of the bar B.
