MEANS FOR EXCLUDING FLIES FROM BUILDINGS.

the present specification is confined may beemployed in connection with fly-proof entrances differing in construction from those set forth in said companion specification.

The leading objects of the present-invention are to prevent the entrance of flies into a building or an apartment by way of wickets for the delivery of goods, or of the exit doorways.

Other objects will be set forth in the general description which follows.

Three sheets of drawings accompany this specification as parts thereof.

Figures 1 and 2 are perspective views of an oscillating wicket constructed according to this invention; Figs. 3 and 4' are horizontal sections of the same, showing its doors in the positions represented by Figs. 1 and 2 respectively; Figs; 5 and 6 are horizontal sections thereof showing the doors in other positions; Figs. 7 and 8 are detail views of its latch on a larger scale; Figs.

9 and 10 are large-scale detail views showing respectively the spring hinge and telescopic construction of its secondary door; Figs. 11 and 12 are. plan views of a rcvolv ing exit door for persons, constructed on the same principle.

Like reference characters refer to like parts in all the figures.

The wicket a and exit 6, whichtogether constitute the means of the presentljnvem tion for excluding flies from bu'i dings or apartments, are constructed; in common, with a vertical axis of motion; and with radial main doors, 1 and 2, or l 2' 3 and 4 rigidly united by a pivot post, 5, forming sector-shaped passageway spaces between Specification of Letters Patent.

them, and turning within a suitable housing formed in part by a segmental wall, 6 or 6'; together with secondary swinging'doors, 7 or 7 ,-between the main doors. The secondvarydoors, 7 or 7, are also, in common, provid'ed'with peculiarly operated latches, 8, hereinafter more particularly described, one of which'is shown in detail by Figs. 7 and 8, andwith spring hinges, one of which is represented at 9 in Fig. 9, by which each secondary door 7 or 7 is normally held against the back of the main door to which it belongs, and is restored to this position after being temporarily detained in its fly: excluding position, while the main door moves away therefrom; the unlatchingcon tact of a main door with the secondary door being ada ted to kill any flies that maybe between t e two. Said latches 8, common to both devices, are of the following construction: (See Figs. 7 and 8.) A housing, 10, adapted to be fixedly attached to the secondary door 7 M7 and suitably recessed, guides a horizontally slidable bolt, 11, the protruding end of which is or may be beveled, and which is provideclwith a longitudinal spur rack, 12, engaged by a pinion or sector, 13, forming the hub of a lever arm 14.- A coiled spring, 15, keeps the bolt 11 normally protruded; and the lever 'arm 14 and 'rack and pinion connection are retracting means. The spring hinges -9, Fig. 9, may be of any suitable known or improved construction; as may also said latches 8; neither of them forming any part of the present invention, as regards their details of construction.

The housing of the wicket a, Figs. 1 to 6, inclusive, shown at 6,. is adapted to be sup ported upon a sales counter, 0, Figs. land 2, 1n juxtaposition to an o ening fitted thereto and formed in a vest1bnle.wall, d, or the like, which is further provided with a conveniently located cash slot, 0, as represented in the same figures. The housing is sectorrshaped and opematboth radial sides thereof; itinclhdes horizontal top and bottom members, '16 and 17, in addition to its segmental wall 6; and its pivot post 5 has I bearings in said top and bottom members. Its inner and outer main doors land 2 are l j i provided respectively witha handle, 18,

and with a latch-retracting projection, 19,

adjoining which a recess admits more or less of the latch as required. Its latch 8 is carried by the opposlng side or back of its secondary door 7, which is pivoted with 4 the aid of one or more of said spring hinges seco ndary door 7, the latter is constructed fwit'li a telescopic free edge, 21', shown in detail by Fig. 10; which see. The outer edge portion" (21) is projected by the customary springs 22, .and its projection is limited by stops 23. The overlapping portions may position of rest, Figs. 1 and 3, into the re-- ceiving position represented by Fig. 5; the

secondary door 7 being in contact with the vto preferably be made of thin sheet metal so as .to be substantially flush.

The main doors land 2 are connected at their lower edges by a bottom, 24, on which parcels are 'placed by the salesman after pulling the wicket by the handle 18 from its back of the inner door 1, and the entrance of flies prevented by the outer door 2' within the housing. The wicket is then moved by the salesman to its delivering position, Figs.

2 and 4, and the parcels are removed by the purchaser. The outward movement of the wicket is continued until it is arrested by a stop, 25. At the same instant a catch recess, 26, admits the bolt 11 of the latch 8 twin Fig. 4, and the secondary door 7 becomes 'fastened in the outer opening of the wicket housing, so as toexclude flies therefrom during the return movement of the emptied wicket, as represented by Fig. 6. Toward the end of this movement, the projection 19 of the outer door 2 comes in contact with the lever arm 1 1 of the latch 8, and retracts the latch bolt 11; permitting the secondary door" 7 tobe thrown into contact with the back of the, inner main door 1 by its spring hinge 9. I The movement of-the wicket from this position (Figs. 1 and 3) to its receiving position (Fig. 5) is limited by the wall d through which the passageway of the wicket' extends.

The housing of the fly-proof exit 6, Figs. 11 and'12,in addition to its segmental wall 6, has a nearly circular top, 27, Fig. 12, and diametrically opposite said segmental wall has a segmental guard, 28, whichmay preferably be a railing or grille, as 'indicated, and of larger radius that the segmental wall, so as to obviate making the second ary doors 7: telescopic. These secondary be otherwise of the same construction, excepting-dimensions, as the secondary door 7"'above described; having in common therewith latches 8 and spring hinges 9 as already described. For tripping the latches 8, each of the main doors 1 2' 3' and 4: is likewise constructed with a retracta mg projection 19 and a recess 20 adjoining the same similar to those above described. In this device the main doors 1' 2 3 and 4 are adapted to be revolved continuously by persons leaving the fly proof apartment from. which the exit passageway leads; the

latches 8 interacting successively with a striking plate, 30, attached to a post, 31, at the outer end of the segmental guard 28.

With the doors.1 2 3 4' and7' in the positions represented .by Fig. 11, the main door 1' has just released one of the secondary doors 7, from the post 31, and is about to leave in its place the secondary door 7 normally carried on the back of said main door 1. In this condition of the exit, both of the outer doorways, 32 .and 33, of the exit are closed by the main doors 2' and '1- respectively, and ersons may be supposed to be between the the doors 3, and 4 and pressing against the backs of said doors 2 and 3 respectively as represented by the arrows a: and 3 An instant later the parts would appear as shown in Fig. 12; the person or persons represented by said arrow :1: leaving the exit, and the oors 2 and 3' and between space between the doors 4 and 1' opening ed by the door 3 interacting with the fly-' proot segmental wall 6, and the doorway 33 -is closed by the secondary door 7 left by the main door -1. \Vhen the main door 2' reaches this secondary door 7 the projection 19 of the main door trips the latch 8 of the secondary ,door, and the latter is thrown by' its spring hinge, 9 into its normal position again, in contact with the back of the main door 1; the next secondary door, normally in contact with said door 2, taking its place .as the obstruction of the doorway 33 against the entrance of flies. The entrance-of persons between a main door and its secondary door is prevented by the uard 28; and as the doorway 33 adjoining t e same is always closed, either as shown in Fig. 11 or as shown in Fig. 12, said guard need not be flyproof. 7

' The exit 6 represented by the drawings is one of a pair made right and left respectively and arranged at the respective inner angles of the rectangular inner end of a vestibule, in connection with a separate fiyproof entrance, as set forth in said compan- 1011 specification.

For the purposes of the present lnventlon the fly-proof entrance or entrances may be of any known or improved construction.
