DOOR.

Specification of Letters Patent. Patented June 3@, 1914.

Application filed June 14, 1913. Serial No. 773,588.

To all whom it may concern Be it known that we, FRANCESCO Roman and PASQUALE Ronnnri, both subjects of the King of Italy, both residing at Fitchburg, in the county of Worcester and State of Massachusetts, have invented a new and useful Door, of which the following is a specification.

This invention relates to a door and the casing therefor and comprises a substantial construction of door, casing and means for connecting them whereby the joint between the door and casing will remain closed in all positions of the door so as to prevent the passage of light and also to a large degree to exclude noise and dust and yet to provide an extremely simple construction and one which can be dismounted very readily without the use of special tools.

Reference is to be had to the accompanying drawings in which,

Figure 1 is a front view of a door and casing constructed in accordance with this invention; Fig. 2 is a sectional View of the same on enlarged scale on the line 22 of Fig. 1; Fig. 3 is a similar view showing the door partly open; and Fig. at is an inside view of a portion thereof showing one of the hinges.

The invention is shown in a form in which the casing is made up of an outer member 10 and inner member 11. At the end of the outer member is located an upright member 12 which forms the vertical wall of the casing visible from the outside. The joint between the members 10 and 12 is shown as closed by the plate 13. A. plate 14 similar to the plate 13 is shown on the inside for covering the edge of the casing at 11. Beyond the upright member 12 and between the members 10 and 1a is a space 15. The inner vertical edge of the member 12 isprovided with a shallow groove 16 for a purpose that will appear hereinafter. On the inner edge of the member 12 are secured the socket members 20 of the hinges. Each of these is provided with a socket 21 consisting of a hollow cylinder. The sockets 21 are located in the groove 16 and fit the same. The other members of the hinges comprise in each case a plate 22 and a housing 23. This housing has a cylindrical passage therethrough opening at the bottom and also if desired at the top. Below this housing isanother housing 24: which has a similar passage. The space between these two housings is commensurate with the length of the socket 21 so that when the two parts of the hinge are placed together these parts form a continuous cylinder. At this time also the two housings 23 and 24 fit the groove 16. In the housing 23 is a bolt 25 and adapted to be projected down through the socket 21 into the housing 2st when the parts are in the position shown in the first three figures. For the purpose of operating this hinge pin readily without the use of special tools, it is provided with an arm 26 extending out at right angles through a longitudinal slot 27 in the housing 23. At the top, of this slot it is provided with a horizontal offset 28 which supports the arm when the hinge pin is moved up as shown in Fig. l. These hinge members 22 are fixed to the edge of the door 30. This edge of the door is made slightly slanting and it is provided with a projection 31 which extends in back of the rounded surfaces of the housings 23 and 2 1 and is continuous from top to bottom. This obviously projects in beyond the edge of the groove 16 when the door is closed, as shown in Fig. 2.

On the inner face of the door 30 are hinges 32 each made of any ordinary character and of small size. These hinges support a member 33 which is thus pivoted to the inner edge of the door and capable of sliding in and out of the space 15 as the door swings. This sliding member is provided with an edge groove 34 to permit it to pass over the cylindrical portion of the main hinges. When the door is closed this brings this member 33 up into the position, indicated in Fig. 2, so as to close the opening entirely. When the door is partly open it also closes the opening except for any space between the hinges 32. At no time is there any possibility of an opening appearing at the edge of the hinges 20-22 for this space is filled by the construction of the hinge, door and casing. When it is desired to take the door olf, the hinges 32 are first taken off the door, which can be done easily as the heads of the screws are readily accessible. The member 33 is then moved back into the space 15 and the arms 26 manipulated to raise the bolts and hold them raised. Then the door can be lifted 02d. It-will be obvious that it can be moved back into place in a very simple manner without any danger of disarranging the hinges by which it is supported.

itrlthongh We have illustrated and described only a single form of the invention, we are aware of the fact that many. niodifications can be made therein by any person skilled in the art Without departing from the scope of the invention as expressed in the claim. Therefore, We do not Wish to be limited in these respects, but

What We do claim is 10 The combination with a door casing having a transverse upright extending only part Way across the casing and havinga space behind the upright, opening at the edge thereof, of a door hinged to the edge of said upright and a free vertical member pivoted 15 to the door on the side thereof opposite said upright and movable freely With the door through said opening and in said space as the latter swings.

In testimony whereof We have hereunto 20 set our hands, in the presence of two subscribing witnesses.
