VAU'LT-VESTIBULE.

v Specification of Letters Patent.

Patented Aug. 10, 1920.

To all whom t may concern:

Be it known that we, Mosns MosLER and CARL BARTnLs, citizens of the United States, residing at Cincinnati, Hamilton county, Ohio, and Hamilton, Butler county, Ohio, respectively, have invented certain new and useful Improvements in Vault-Vestibules, of which the following is a specification.

This invention, pertaining to the vestibules of vaults, relates to a construction of steel castings, and the improvements will be readily understood from the following description taken in connection with the accompanying drawings in which Figure 1 is a front elevation of a square door vault vestibule embodying our present improvements, portions appearing in vertical sections in the plane of line a of Fig. 2:

Fig. 2 a horizontal section through a portion'of the vestibule wall and door in the plane of line Z2 of Fig. 1, the door appearing as not being entirely closed: and

Fig. 3 a rear elevation of the juncture between one of the side walls of the vestibule and the contiguous vault wall.

A diversity of scales is employed in the drawings.

In the drawings Y 1, indicates the wall of the vestibule:

2, the door thereof, the door being illustrated in the exemplication, as square:

3, the front wall of the vault, which is joined by the vestibule at the doorway:

il, the stepped janib of the doorway:

5, one section of the vestibule wall, the same being a steel casting with its rear eX- terior joining the wall 3 of the vault:

6,'a typical means for uniting the section 5 to the vault wall, the same consisting of dovetailed keeper blocks engaging dovetails on the contiguous portions of the vault wall and the vestibule wall:

7, the second section of the vestibule wall, the same seating against the front of the section 5:

8, the thirdsection of thevestibule wall the same seating against the front of the section 7: Y

9, the frontsof the several sections 5, 7 and 8: f

9', dovetailed grooves formed in the fronts of the sections 5 and Z 10, dovetails formed 'at the rear of the sections 7 and 8 and fitting looselyin the dovetails 9' i 11, filling strips driven tightly between the side engaging surfaces of the dovetails uniting the several sections:

V12, the front section of the door:

13, the next inner section of the door:

14, the inner section of the door:

15, thebolts of the door: and 16, filling strips driven into the spaces between the succeeding door sections, these door sections being dovetailed to each other in a manner similar to that in which the vestibule sectionsjoin each other; and 17, packing of yielding material at the face of one of the steps. l

lhile the vestibule and the door may be formed each of any desired number of sections, the illustration assumes three sections in each, the door-j amb, and the door-margin being formed with three steps. Each vestibule section is formed of an integral steel casting, and the rear section 5 is to be'joined, in any desired manner, to the front wall 3 of the vestibule, as for instance, by means of the keeper-block 6. The contiguous sections of the vestibule wall engage each other by loose dovetailing, the looseness being later taken up by the filling strips 11 which are tightly and permanently driven' in place. The steps 4L of the door-jamb are beveled, and the beveling of these jambportions serves in providing portions of the dovetailed junctures between neighboring sections.

The door is formed of sections dovetailed together in a manner similar to that employed in joining the vestibule sections, the tapers of the steps on the margin of the door forming elements in the union of the door sections. 'By this system of construction, any desired thickness of door and door-jamb may be secured while maintaining comparatively thin individual wall sections.

In assembling'the vestibule the casting constituting a given section, say the section 5, is first taken in hand, this section forming the top, bottom and both sides of one step of the doorway. The neXt section 7, similarly constructed, is then to be placed in its dovetail connection with the section 5 and the filling strips are to be tightly driven, thus securing the two sections of the doorway firmly together. The next section is 8, to be similarly joined to the preceding two sections. A similar method of assembling is to be employed in connection with the door,

each section of which' embodies the top, bottom and two sides of one step of the door.

. strips shallower than the depth of the groove in which they fit, the front of the groove being filled with the packing which would project a slight distance beyond the face of the step. Y

By means of the described systemof construction not only may the doorway and door be built up to any vdesired depth, but it is our preference that hollow manganese steel castings beemployed in building up the structure and in thel drawing we illustrate the sections of door and wall as being hollow. lt is preferable that the hollows of the sections be strengthened by means of girts cast across the cavities, as shown.A -By thus employing hollow sections formed of manganese steel castings, the. walls of the cavities, may be comparatively thin,rthus permitting of the satisfactory heat treatnient of 'the kmanganese steel, In case the sections be formed' of hollowcastingsY the cavities in them may, if desired, be filled with any suitable fireproofing or otherinaterial.
