Specification of Letters Patent; Patented Dec, 24, 1912, applicati@ mea January 27, 1910. serial No. 540,348.

To all 'whom it may concern: t

Be it known V'that I, VACLAV CERNY, a

citizen of the United States,-'and a resident-- of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hinges; and I do` hereby declare that the following is a full, clear, and exact descriptionthereof, reference being had tothe accompanying drawings, and to the characters of reference marked thereon, which form a part'vof this specification.

This invention relates to improvements in hinges for side walk trap doors and other generally like uses, and the invention con sists in. the matters hereinafter set forth and. more particularly pointed out in the appended claims.I l Amongl the objects of the invention is to provide an improvement in hinges for this purpose in which the arrangement of the hinge and the door frame is such that the connection of ,the hinge to the frame rein-- forces and strengthens the latter, and to provide means for connecting the hinge fand frame in such manner that the hinge meme ber carried bythe frame may be removed without disturbing the frame or the cement in which the frame may be partially embedded. Other objects of the invention are to produce an exceedingly strong and durable hinge which may be made at small cost i and which will require no `special machine operations to assemble Athe hinge members.

enlarged vertical sectional view of the hinge on line 3-3 of Fig. 1.- Fig. I4 is a face view of the fixed hingemember attached to the.

door frame bar. 4Fig. 5 is a detached view of the swinging member of .the hinge As shown in the drawing, 10- designates the door which fits in a horizontal rectangular frame that is supported in the side walk around an opening therein in any suitable manner. Said framev is shown 'as composed of angle bars 11, 11,1 the upper horizontal flanges 12 of which are arranged flush with.

the upper face of the side walk, and the vertical webs 1,3 of which extend into the side walk opening at the side thereof. Stops 14 are attached to the inner `sides of the frame bars to support the door in its closed position. Two hinges swingingly connect the door with the frame and the following descrip'- tlon is directed to a single hinge.v

' Each hinge comprises a'ixed member 15 60 and swinging member 16. .The latter mem# ber is attached to the door near the edge of the door, and the former is attached to thev angle frame bar at one sideofthe door opening. The swinging member 16 of the 65 hinge comprises a flat .attaching web orplate 17 that fits flat against the under side of the doorl and is attached thereto by the screw bolts 19, and a downwardly and rearwardly curved bearing arm `20 which ex- 70 tends beyond the outer edge of the door and is provided at its outer end with oppositely extending lugs or pintles 21 arranged trans,- versely-to theplane of the arm. l

The fixed hinge member comprises a holl75 low shell-like bodythat is open at its top and also at its frontto receive the arm 20 of the swinging member. Said fixed member extends outwardly through an opening in the vertical web of the 4angle`frame bar 11 80 and fits atits flat open upper side against the lower face' lof the'horizontal ange of the angle frame bar. -Itis formed at its frontl` side with a flat flange 22 which fits against the front face of the web 13 of the 85 'near the top thereof with interior. semicylindric, upwardly facing bearing sockets l 25, 25. These bearing sockets receive the lugs or pintles 21 of the rearwardly curved bearing arm of the swinging member of the hinge, said bearing sockets and the lugs or pintles constituting the hinge axis about which e the swinging member turns. The body is hollowed out below and at the outer side of said bearing socket to receive thev curved bearing arm when the hinge is in its closed position, as shown in Fig. 3. The

fixed member of the hinge is attached to the angle frame bar after the swinging member thereof has been interlocked therewith, and when said fixed member is inserted through the opening in the web'of theframe bar 11,9

theA rearwardly extending 90 and fixed with its open side fitted up against the fiange of saidbar, the lugged bearing arm will be locked in the hollowfixed member of the hinge.

The flange 22 at the front side of the fixed hinge member extends fro-m the upper to the lower side of the vertical web 13 of the frame bar so as to cover the opening in the frame bar through which the fixed hinge.

member extends. It will be observed that the upper open side of the fixed hinge member fits with a relatively wide bearing against the under 'face of the flange of the ,tion indicated in dotted lines in Fig. 3.

It will be observed that the door or swinging member of the hinge is located below and is entirelysconcealed by the door; so that the side walk has no projecting parts that extend above the level of the door against which the foot may strike. Furthermore, the said hinge, being located lbelow the door, does not receive the wear to which an exposed hinge is subjected when placed upon the side walk level. Another advantage of the hinge is the ease and facility in which it may be assembled, there' being no parts requiring machining to assembleor to apply the hinge in place. It therefore becomes possible to very materially cheapen the cost of producing the hinge, as 4compared to hinges requiring the parts to be machined and having a number of parts to be assembled. The construction of the hinge and the manner of its attachment to the frame bar is such that the fixed member ofjthe hinge stiffens or reinforces the frame bar Y at its notched part which receives said fixed part of the hinge.

I claim as m invention: l I

1. The combination with a trap door and its fra-me, Athelatter composed of angle bars having vertical webs and horizontal, outwardly directed fianges, of a hinge'therefor comprising a hollow fixed member, provided at its inner side with a slot, and a swinging member, the web being provided with an opening o-f a width to permit the fixed member to pass therethrough and the fixed member extending outwardly through the opening of the web and having means accessible from the inner side of said web to removably attach it to said web, and the swinging member being attached to the under .side of the door and provided with a bearing armthat extends into the hollow xed member through its slot and is pivoted vto said fixed member.

2. The combination wit-h a trap door and its frame, the latter composed of angle bars, thel webs of which are vertical and have openings to receive the fixed members of the hlnges and the horizontal anges of which are unslotted and are directedv outwardly and arranged in the plane of the door, of hinlges therefor, comprising hollow fixed members havingv end, rear, front and bottom walls and open at their to-ps and fitted to theunder sides 'of the fianges in the angles between the flanges and the webs of the,

frame barsl and extending through said openings of the web, the inner walls of the fixed members .-bein slotted and extending at their ends beyon said end walls to coristitutevflanges which. lap over the front faces; of said webs and are removably attached thereto, and swinging 'members attached to the under side of. the door and extending through the slotsvin the inner walls lof the fixed members for pivotal connection having vertical webs and outwardly extending flanges, of a hin e therefor comprising a hollow fixed mem er and a' swinging member, said fixed member extending outwardly through an opening in the vertical web of the frame bar, and being open at its top and providedat its inner side with a slot and at the sides of said'slot with flanges whichfit against and are attached'to the inner side ofthe web of the frame bar, the upper open side'of the fixed member fitting up against the lower side of the horizontal flange of the frame bar and provided with interior bearings and the swinging hinge member comprising an att-aching plate or flange attached to the under side of the door and an outwardly extending arm which exv tends intov the hollow xed member and is VACLAV CERNY.
