MEGHANISM'FOR OPENING DOOR-S;
Specification of Leas Patent, P t ted O; Q 1
Application filed January 30, 1917. Serial No. 145,382. i
To all whom it may concern."
Be it known that I, GUsrAv A.-AN'nnnsoN, a citizen of the United States, residing at Baltimore, in the State of'Maryland, have invented certain new'and useful Improvements in Mechanism for Opening Doors; and I do hereby declare thefollowingto be a full, clear, and exact description of'the invention, such as will enable others skilled in the art to which it appertains to'make and use thesame. g 1
My invention relates to mechanism for opening doors. One object of myinvention is to provide a spring operated mechanismforopening the doors. I Y I 1 Ileretofore doors similar to those shown in the accompanying drawingshave been I opened through the 'instrumentality of weights but owing to the accelerationfof gravity upon these weights,-undue stresses have been applied to the leaves of the doors and their sup-porting"hinges; I v V I find by the use of my improved spring opening device hereinafter illustrated and described,'that I cansecure a very rapid opening of the doors and reduce the stressesupon theleaves thereof and their supporting; hinges to minimum, thus greatly increasing the life, of these parts.
In carrying out myinvention, I make use of the instrumentalities illustrated in the accompanying drawings, wherein Figure 1 is a view of a pair of folding doors equipped with my improved devices, the doors bein shown in the closed position;
Fig. 2 is a side elevation of my improved pulley;
Fig, 3 is an inverted plan view of said pulley;
Fig. 4 is a side elevation of the support for the spring pulley;
Fig. 5 is a section along the line 0-9 of Fig. 3, looking in the direction of the arrows; and
Fig. 6 is a plan view of the support shown in Fig. 4.
In the drawings, 10-10 represent the side posts of the door, and 11 the lintel thereof.
To the side posts 10-10 are attached in any approved manner, the fixedmembers of the hinges 12-12-12-12. The hinges 12 are of any approved construction and these may be any suitable number of same l 1 v I Movable members 28-28-28-28 of the hinges, are'secured to the leaves 29-29 of the folding doors.
The leaves 30-30 of the folding "doors are hinged to the leaves 29-29 by hinges such as 31-31, the hinges 31 being of any approved construction.
t The side-posts 10-10,'the leaves 29-29, the leaves 30-30, and the various hinges are so arranged that when the leaves are in the position shown in Fig.1, their edges will fit together and form a good closure.
The bolts 32-32, 35-35, the levers 37-37, the various supports for the bolts, and the mounting of the levers, areall old and well-known in the art. i
, Cords 38-38 areconnected to the upper end of the bolts'32-32, and a cord 39, provided at one end with a pull ring 40, passes over the pulley 41, and has its other end connected to the cords 38-38. lVhen theleaves 29 and30 aremoved into the position shown in Fi 1, they. canbe secured in this position applying the hands to thehandlcs 42-42, and moving the bolts 32-32downwardly until their lower endslprojectinto the holes This downward movement of the bolts'32-32 alsomoves the bolts 35-35 upwardly until their upper ends project into the holes 36-36.
In order to guide the free edges of the leaves 30-30 when the door is being opened, I attach guiding trolleys 42-42 to the upper portions of the leaves 30-30 near their free edges, and mount the rod 43 upon the lintel 11 in any approved manner, so that the trolleys 42-42 can be guided by the rod 43 and thus guide the free edge of the leaves 30-30.
In order to provide for the opening of the door, I mount brackets 4444 upon the side posts 10-10 near the juncture with the lintel 11. Upon the brackets 44-44, I secure the base piece 45, (see Figs. 2, 4 and of pose hereinafter referred to. Formed integrally with the upper end of the cylindrical portion 49 is a threaded stud 51, and a nut 67 threaded thereon secures the spring pulley in place upon said stud.
My spring pulley is formed of a disklike portion 52, with a hollow cylindrical portion 53, and flanges 5454. My improved pulley is also provided with an inner hollow cylindrical portion 55, having the slot 56 formed therein. The edges of the slot 56 are beveled as shown at 57 in Fig. 6. My improved pulley is also provided with a hole 58 which is of such a size that the small cylindrical portion 49 of the support 45 can revolve freely therein. The large cylindrical portion 48 is of such a size as to revolve freely in the interior of the hollow cylindrical portion 55 of my improved pulley. My improved pulley is also provided with a hole 59 for the reception of a cord 60, the latter having a knot 61 on one end which rests in the space between the cylindrical portions 53 and 55 of my improved pulley.
I use one of iny improved pulleys for each pair of leaves 29 and 30 and each of the cords 6060 has its free endattached to the trolley 42, each of the trolleys 42 being mounted near the upper end of the free edge of the leaf 30.
In order to provide a spring pressure, for a purpose hereinafter explained, I provide the spring 63 which has its inner end 64 bent inwardly and mounted in the slot 50 of the cylindrical portion 49 of the support 45, and has its outer end bent outwardly as at 65, and mounted in the slot 56 of the pulley.
The operation of my improved spring pul leys is as follows When the leaves 29 and 30 are in the position shown in Fig. 1, the cord 60 has about the same relative position to the cylindrical portion 53 of the pulley as is shown in Figs. 5 and 6. In this position, the spring 63 produces its maximum pull upon the cord 60.
Hence when the ring is pulled and the bolts 32-32, 3535 are removed from the holes 33 33, 36-36, there is a maximum outward pull uponthe trolleys 4242 and this causes the leaves 29 and 30 to move rapidly from the position shown diagrammatipally in Fig. 3 to that similarly shown in IVhen the leaves 29 and 30 are as shown in Fig. 4, the spring 63 is so arranged that there is practically no pull upon the cord 60.
Hence it is evident that by this arrangement, I am able to have a maximum pull upon the leaves 29 and 30 at the beginning of the opening movement, and insure that there shall not be any violent shocks of these leaves and their supporting hinges when the opening operation is completed.
I claim The combination with a spring operated pulley comprising a disk like portion provided with a hole, an outer cylindrical portion for supporting a cord, and an inner cylindrical portion forming a spring housing, of a support for said pulley comprising a base, a disk like portion forming a bearing for the interior of saidinner cylindrical portion, a small cylindrical portion revolubly mounted in said hole, a slot in said small cylindrical portion and a spring having one end secured in said slot, and a slot in the inner cylindrical portion of said pulley securing the other end of said spring.
In testimony whereof, I aflix my signature.
GUSTAV A. ANDERSON.
