UNITEDl STATES 1,603,678 PATENT OFFICE.
FREDERICK I. FUBEY, 0F LONG BEACH, CALIFORNIA.
Gamme.
Application led December 11, 1924. Serial No. 755,161.
This invention relates to gratin such as is used for basement covers, manho e covers, fire escapes, stair case treads, etc.
It is an object of this invention to provide a grating4 of this character which will be superior to other gratings, inasmuch as it will possess great stren th. The grating of my invention is especia ly designed to have a minimum of flexure, either in a transverse or a longitudinal direction. I .accomplish this object by roviding a grating having transverse mem ers and longitudinal members which cross one another and are secured together. I
It is a further object of my invention to provide a grating 'of the character mentioned having a novel joint for securing the transverse and longitudinal members together, this joint being extremely durable. 'Ifhe transverse members of a grating of my invention are wave-shaped and are arranged so that alternate points or crests of adjacent transverse members engage. At the point of engagement I provide slots ,and openings in a manner to form bridges. The longitudinal members are provided with openings defining longitudinal bridges abovesaid openings and securing lugs situated adjacent to and below said openings. The longitudinal and the transverse members are assembled in such a manner that the bridge portions of the transverse members extend through the openings in the longitudinal members anduso that the lug portions serve to securely retain the bridges in the openings.
tIt is a further object of my invention to provide a grating of the character mentioned which may be produced at a small cost. I accomplish this object by providin grating of such a design that it may be rea ily made by a few simple operations.
Other objects and advantages .of the invention will appear in the following description. l
Referring to the drawing in which I show a preferred form of myv invention solely for illustrative purposes,
Fig. 1 is a fragmentary perspective view of a grating embodying the features of my invention.
Fig.l 2 is a section taken on a line 2-2 of Fig. 3 is a section taken on a line 3-3 of Fig. 1.
Fig. 4 is an enlarged fragmentary perspective detail of certain members of the grating shown in Fig. 1, these members being disposed in a position previous to the .previous to the locking together thereof.
Fig. 6 is 'a view similar to Fig. 5, but
owing members locked together.
With particular reference to Fig. 1 of the drawing, the form of my invention shown comprises transverse members 11'and longitudinal members 12. The transverse members 11 are waveshaped as shown, and are arranged so lthat alternate points or crests 13 of adjacent transverse members contact, thus forming diamond-shaped openings. At the points 13 of the wave-sha ed transverse members 11 slots 15 are .provi ed, these slots being cut from the top edge of' the members 1l in such a manner as to -provide lower transverse bridge portions 16, the slots of the adjacent transverse members aligning as ed with openings 18 defining upper longitudinal bridge portions 16 and the web portions 19 below the openings 18 are sheared at 20 so as to provide securing lugs 21. When the members 11 and 12 are assembled as shown in Figs. 1, 2, 3, 5 and 6 of the drawings, lower transverse bridge rest iii the openings 18, these ridge portions 16 being retained in the openings 18 by m'eans of lugs 21 engaging beneath said bridge portions. A rim member 23 is extended around the ating, the ends of the transverse and longitudinal members 11 and 12 being secured thereto as by welding as indicated at 24 in Fig. 1.
In constructing the grating of my invention the lugs 21 are bent as indicated in Fig. 4, these lugs being bent substantially on dotted lines 26 of Fig. 3, so as to provide a receiving throat 18a affording access to the openings 18.
After the transverse members 11 are po sitioned as shown in Fig. 1 they are assembled with the longitudinal members 12 substantially as shown in Fig. 5 of the drawbent into securing position beneath the bridge portion 16 as showny in Fig. 6, thus retaining the bridge portions 16 of the transverse members 11 in the openings 18 of the lon itudinal members 12 With the side Walls of t e slots 15 embracing the upper longitudinal 'bridge portions of said longitudinal members. Experience has proven that the lug members are suiiciently strong to endure any stresses applied on either of the members tending to separate them. However, ii desired, the lug members after they are bent into securing position may be Welded.
l am able to provide an extremely strony grating due to the tact that 'the longitudine and the transverse members cross one another and are rigidly secured together. rEhe securing of each ot these members with one another provides a grating which presents a maximum resistance to tlexure, either in. a transverse or a longitudinal direction.
lThe construction of the grating is simpley and the mechanical Work necessary is very small; therefore, the grating may be produced at a 'fairly 10W cost. lt is obvious that the shaping oi' the parts and the assembling and securing ci these parts require but small labor.
l claim as my invention:
l. lin a grating o'f the class described, the combination ot: longitudinal members having relatively spaced transverse openings each defining an upper longitudinal bridge portion and a lower web portion split to form locking lugs; and Wave-shaped transverse members slotted from their upper edges downwardly at the crests ot each alternate bend and to a depth to leave adjacent lower transverse bridge portions, the members being assembled so that the lower bridge portions ot the transverse members extend through said openings in the longitudinal recaen members with the side walls of said slots embracing the upper .iongitudinal ybridge 2. lin a gratin f of the class described, the
combination of: ongitudinal members havingl openings which connect with slits which extend through the edges of said members.; and transverse members slotted in one edge thereof and adapted to be received in said openings throu h receiving throats 'formed by bending asi e the material adjacent the slits, said transverse members being retained in said openings by said material when saine is rebent to normal position and beneath the unslotted edge of sald transverse members.
3. ln a grating ot the class described,7 the combination of: a longitudinal member having an opening formed therein; cooperating lugs formed adjacent to said opening, said lugs being adapted to be positioned to iorin a receiving throat connecting said opening with an edge of said longitudinal member; and a transverse member slotted in one edge thereof and adapted to be extended into said opening through the throat connecting said opening and said edge, said lugs being movable into a position to close said opening and to engage beneath the unslotted edge or" the transverse member to secure said transverse member in said opening.
ln testimony whereof, l have hereunto set my hand at Los Angeles, California, this 6th day of December, i924.
