.577 @woah ATTORNEY Patented Nov. 19, 1929 UNITED STATES JOHN J'. BEI-IEN, OF SOLEDAD, CALIFORNIA COMBINATION "WEATHER STRIP Application filed .Tune 1,2.

My invention relates to weather-strips and particularly to that type adapted to seal the space beneath a door so as to exclude weather and dust, and if desired the threshold may be dispensed with; it further relates to a doorstop adapted to hold the door at any position of the opening arc; and furthermore, relates to an alarm bell which automatically gives warning when the door is opened.

The objects of the invention comprise the following desideratuinsz- To provide a vertically-operable weatherstrip member carried by a door between the bottom thereof and a floor or threshold said strip being provided with rubl er or other suitable yielding lower surface adapted to make close contact with a floor.

To provide bifurcated cranks forking a push-shaft to impart even up and down move- 2o' ment to a weather-strip; to provide dual means for axial displacement of said shaft, one means being automatic with the opening or closing of the door, the other operated by pressure of the foot upon either of two pedals,

one being disposed at each side near the swinging lower corner of the door.

To provide a bell that Will sound an alarm whenever the weather strip is raised or lowered.

3o' `With the foregoing and other advantages,

the invention consists in the novel construction, arrangement and combination of parts,l

particularly defined in the claims and illustrated in the accompanying drawings, in which Figure 1 is a longitudinal sectional elevation of my invention taken on the line 1 1 of Fig. 2.

.Figa 2 is a section taken onV the line 2-2 the lower portion of a hinged door and rela-A 507 tive components of my invention.

1929. Serial No. 370,335.

provided with the medial groove 4 milled up vertically for the full widthv thereof. Said groove being of suiiicient width to receive the frame of thedevice as is well shown in Figs. 1, 2, 3 and 4. Said frame comprises the upper structure 5 with the ends Gand 7 respectively. Said structure being a snug lit up into said groove; but the respective end plates 6 and 7 are preferably of sufcient width for the screws 8 to secure the structure 5 to the door structure at each side of said groove, as is clearly indicated by the dotted lines 6 6 in Fig. 2, the door structure being gained out to receive said plates.

rEhe

main bearings

9, 10 and 11, as Well as the plate 7 are suitably drilled to carry the main shaft 12 in axial alinement with the groove l and in a horizontal plane.

Said shaft being adapted for pre-determined aXial displacen'ient.

The cam-plate 13 is rigidly secured tothe shaft 1 2'by a pin as 14 or in other suitable manner.

ihe adjacent face of said plate and the bearing 9 Contact with the relative sides of the stop cranks 15 or 15a as the case may be.

In my preferred construction as shown in F 1 the pivotal axis 16 ofthe crank 15 is disposed beneath the lshaft 12 whereas, in a second embodiment, shown in Fig. 7, the crank 15EL is pivoted above said shaft 12.

Said pivot 16 is preferably of square section and passes transversely through the door and through a square opening in either of said cranks 15 or 15a with enough end projecting at each side of the door to mount the socketed Aflanges 36 and 36a. The hubs 351-351 of the pedal elements fit into the sockets 35h-35b and center the pivotal shaft 16, being held in place by the means 35-35e the projections 35 are stops to limit the pedalthrow in either direction beyond the required throw of the crank 15 or 15a.

To secure the crank 15 from falling to the horizontal-when the door is closed, which traverses the plate 13 to the left, I provide a retaining spring which may be as 37d in Figs. 2 and 3 or as 37zt thepreferred form shown in Fig. 4 wherein the ends of the spring 37a are secured to the

respective fianges

36 and 36a with the bight 37b of the spring passing round in to the front of the crank 15 so as to tighten when the crank is moved to the horizontal, thus constituting a yieldable check t-o prevent said crank falling down and thus locking the device when the plate 13 is remote, a situation which might occur when the door is shut.

To the right of the bearing 9 the compres sionfspring 16h isslipped on the shaft 12, the doublefaced cam-block 17 is rigidly secured to said shaft so asto compress said spring' to a considerable degree and so as to present saidcamfaccs in vertical planes adapted for inter-'engagement with the bifurcated crank 18 whose lower limb 19 extends suitably to the left to make slotted inter-engagement with the` pin'20 yconnecting said limb with the member 21 whichcarries the left end of the weatherstrip element 22, the axis 23 of thelcrank 1S being carried transversely in the bearingrmember 24C depending vertically from the' structure 5 and preferably integral therewith. Passing to the right said shaft 12.is carried by the bearing 10 and 11. yThe spring 16C is under moderate compression between the bearing 11 and the cam-block 17a, the'interengaging crank 18a being a duplicate of the crank 18 previously described, it

ispivoted in the bearing member 211a by the aXis 23a, the ylower limb 19a of said crank making slotted inter-engagement by means of thepin 2Oa with the member 21a which carries the right end of said weather-strip element.

The right-hand portion of the shaft passes through a suitable perforation in the plate 7 `and: has sufficient end 25 projecting to cause suitable axialdisplacement of the shaft 12 by contacting with the abutment member 26 when the door 2 is shut, as will be further explained.

The abutment element comprises the shell 27 and the abutment member 26 which screws tightly thereinto well shown in Fig. 9, the head 28 fittinoF into the counterpart recess 29, said head being preferably concaved on its outer surface 33 and provided with the screw-driver slots 30. Said abutment element is fitted into the frame 3 so as to be in alinement with the center of the shaft 12 when the door 2 `is shut, the flange 32 being let in flush with theframe and is secured thereto by the screws 31, in which relation the concavity 33 can be regulated axially of the recess 29 by counter clockwise movement of the head 28.

The manipulation and action of my novel invention are as follows Assuming that the device is installedas described; then, with thedoor ajar as in Fig. 6 the weather-strip element is well up within the groove .4. If it .is desired to hold the door stationary in any opened position the corresponding limb 34 or 36b must be depressed unt-il contacting with the stop 35 thus movingeither said crank from a vertical to a horizontal position where it remains locked eitherby theenergy eXerted'by the springs 16b and 16c now compressedor by traversing beyondthe center ofltheaxis 1G to the stopI elementV 35, this describedaction of saidA crankmoves the -shaft112 to theleft, thus depressing limbs 19 and '19a of their ref lated cranks, thereby bringing the weatherstrip element 22 down hard against thefloor, causing the element to actas aperfeet doorstop, not merelyby pressing againsta point against the floor, as is the case with other door-stop devices but by applying a stop member to the floor surface which extends for the full width 'of the door. lnthis posit-ion the door will remain until pressure, as of the foot, is applied to the-releasing limb 34- or 36 as the case may be, whereupon the springs 16b and 16C, now released, force the shaft 12 back to the right toits normal position.

llJhen the door is closed the end `25 of shaft 12 abuts intofthe concavity 33 and'the'strip element simultaneously descends and presses onthe floor or threshold as the casemay be; forfloors of various levels from-the bottom of the door regulative adjustment of the throw ofthe

cranks

19 and 19a may be had by manipulation of the abutment member 26 bv screwing it out of the shell 27 said abut ment being adjustedto govern'the most eX- treme floor levels when seated in said shell as shown in F ig. 9. l

As a-means to prevent the crank .15 falling to the left when the door isclosed andthe plate 13 thereby removed to the left, the spring 37d isprovided having `sufiicient resistance tomaintain saidk crank in uprightposition until acted upon by a-Xial displacement of the shaft 12.

The spring 3711 is of a changed form from the spring 37 d, the ends whereof are secured respectively to the

members

36 and 36a with the bight 37 b passing behind the crank 15 under suitable compressionto hold said crank from falling involuntarily, yet being sufiiciently yieldable to permit Ythe proper throw thereof.

In a second embodiment the crank 15afnormally hangs downward until turned up slightly above center asshowninFig. ,7,shy

downward movement of the limb 36h, thus traversing the shaft 12 to the left.

The bell, B is preferably applied as shown somewhat diagrammatically in Fig. 6, this feature is old and needs no further description as a bell, sutlicient to say that it willring when the member 37 is moved horizontally, said member is connected with the cam block 17a by means of the shaft 38 working in the elongated slot 38 so that when the door is opened the extension of the springs 16b and 16c will rasp the member 37 past a means to sound the bell, the bell being sounded by means actuating a weather-strip.
