AUTOMATICALLY-OPEBATENGT WEATHER STOP.

Application filed February 19, 1921.

To all whom t may concern.'

Be it known that we, JOHN Jarras Hrivrs and HENRY ROBERT WAY, citizens of Great Britain, residing at Halifax, in the Province of Nova Scotia and Dominion of Canada, have invented new and useful improvements Stops, of' which the following is a specification.

Our present invention pertains to automatically operating weather strips tor doors, windows and the like and it contemplates the provision of a device whereby when the window or door to which it is applied is closed, the weather strip will be automatically operated to prevent wind, draught, rain or snow from gaining access to the building or apartment equipped with our device.

The invention also contemplates means whereby the device may be made inoperative, such as for instance in mild or favorable weather.

The invention further contemplates the provision of a device that is readily applied and easily removed from a door or window, and one. that will lend quite a 'finished appearance and harmonize rwith otherl hardware at present used by builders in producing finished and up-to-date apartments and buildings.

The invention in all of its details will be 'fully understood when read in connection with the drawings accompanying` and 'forming part of' this specification, in which:

Figure 1 is a perspective view illustrating our novel device as applied to a door.

Figure 2 is a longitudinal Kectional view of the weather strip casing and illustrating the operating mechanism of the device.

Figure 3 is a sectional. view taken in the plane indicated by the line 33 of Figure il looking in direction ot arrows.

Figure 4 is a view similar to Figure 3 but taken in the plane indicated by line ot Figure 2.

Figure 5 is an end elevation ot the door showing in dotted lines portion of member The view for purposes of illustration eliminates the casing 2 but discloses the trip 18 as confined between the member 3 and door 1 when the door is closed.

Similar numerals of reference designate corresponding parts in all the views ot the drawings.

The door 1 and casing 2 are of the ordi- Speciication of Letters aterit.

Serial No. 446,352.

nary well known construction and secured in the door casing 2 is a trip 8.

Properly secured to the lower end of the door is the outer casing 5, having the upper flat portion in which are provided apertures for the reception of screws l or other fastening means Jfor the connection of said casing to the door. This casing 5 is merely a covering :tor the working elements ot' our invention, and may be provided with the lower rolled portion 6. This casing nat urally is stationary.

A stationary plate 5 is also secured to the doorI through the medium ot the fastening members or screws il and rests between the casing 5 and the door 1, and said tening` screws pass first through the casing 5 and then through the stationary or back plate 5 and finally are secured in the lower end of the door 1.. Secured to the back or stationary plate either by rivets or in any approved manner are ribsv 10 that by preterence are arranged in pairs equiedistantly throughout the length oi? the plate 5', and pivotally secured in the lower end oit the ribs is a rod 9 that supports the inner or movable casing 7 of my novel device.

Arranged between the series of ribs 1() are members 7 that are secured to and are movable with the rod 9 and the said members 7 form an integral part of the movable casing 7. These members 7 are cut away near the upper end as illustrated in Figure 3 and pivotally secured in the upper end of the ribs 1() are alined rods 18 and 131 on each of which is provided a member of the clutch v19. The rod 13 is surrounded by a spring .1 4 which in turn is secured at one end to the casing 7 and at its opposite end the said spring 111 is secured to a collar 1.6 tast on the rod 13. The rod 1.31 is provided with a spring 15 and on the extreme outer end of rod 181 we produce the trip 18.

The rods 131 and 13 may be operated as a unit by turning the trip 18 to the position shown in Figure 2 when the clutch will assume the position shown in said figure.

Our device is simple in construction and operation and may be quickly applied and when building` or other structure is equipped with the device, draughts are precluded entering` said buildingor buildings and hence the danger of colds and diseases to the tenants of the same is materially decreased.

The invention `is particularly adapted for in large oifice and school buildings and in company with the advantages set Vforth, it also tends to reduce the amount otv :fuel used in heating such buildings. Moreover, dust and dirt gaining access to the building is prevented by our device which. feature re-v duces the expensive outlay for labor now einployed for cleaning a large buildinp` as well as wear on the furniture and contents ot said building. t i

The igiullingof the rod 131 outwardly and turning of the trip 18 upwardly will prevent said trip from being oiieratively engaged by member 3 when the door is closed. The rods and 131 carry eccentrics 17 that rest between the sets of ribs l and these eccentrirs 1'? are adapted to engage the cut away endetx the portions 7. As .the portions r7" are movable `with the casing 7 and because lot the Acontact oit2 these eecentrics 1.7 with the upper-end of the portions 7, cloelrwise movement or the revolving' of the rod .13 with. respect to the lugs will naturally impart rotary motion to the eccentrics and in turn operate the casing' 7. The casing 'T is provided, when deemed necessary with the lower channel to `receive a strip 8 of rubber or other weather stripping` material.

4ln the practical useol the invention, when it is desired in cold weather to employ our invention, it is siinply necessary to push the rod 131,' inwardly to lock the clutch 19, The door is then closed and contact of the trin 5% with the trip .18 will cause the cam 18 toy assume the position shown in YFigure 5. This movement of trip 18 willvcause the rods 1? and 131 to rotate and the eccentricO 17 en gagine' the upper ends of the portions 7 wil l manitestly tend to rotate the casing 7 on its axis (the rod 9) and hence `the casing; will be i'orced downwardly toward the sill or Flooringand the strip o'l' rubber or other material. will snugly and iirmly tgrip said sill or floor. Upon release of the trip i8 `from its complementary 'trip 3, by opening of the door 1, the casing- 7 will be returned to its inoperative position due tothe action `of thesprings 1311- aiid 1 5 on rods 13 and 131 which `were under tension when the door was closed.

It will be manifest that the device is automatic in operation, and may either be set for use or the clutch 19 released to prevent operation of the device in mild-weather. It will also be. seen that because ot its auto matic arrangement, marring of' a floor or the diiflicult opening of the door is eliminated and this without the necessity of manually releasing the casing from its operative position.' Moreover, this arrangement re,- lieves the necessity oli' removing,` the device in warm weatheiI and the annoying replacing' of the entire device in cold weather.

W e would distinctly have itii-ndeistood our device is so constructed that the trip 18 simply throwing' the same so that it assumes a position opposite that shown inFigure 5 may be prevented from operating` when desired.
