MCLAUGHLIN HARDWARE ATTACHING MEANS Filed May 18, 1953 l 2 Sheets-Sheet 2 gw 21 l' Snnentor limited ttes Owens-Ford Glass Company, Toledo, Ohio, a corpo-IV ration of Ohio Application May 1s, 1953, sonar No. '355,567 1 claim'. (C1. iss-s6) This invention relates broadly to panel construction, and more particularly to novel means for attaching articles of hardware to glass panels for use as toilet stall partitions and the like. A l

It is conventional practice to construct partitions, doors, and facing members for toilet stall enclosures of laminated panels of opaque structural glass or like material. Problems are encountered, however, in attaching articles of hardware, such as .hinge members and door stops, to the laminated glass panels, that is, due to the brittle nature of the glass panels, the articles of hardware may not be screwed, bolted or nailed thereto, as in the case of wood and metal panels.

It is, therefore, a primary object of this invention to provide novel means for attaching articles of hardware to glass panel constructions wherein undue vstresses will not be placed upon said panel construction. f It is another object of this invention to provide hardware attaching means of the type described whereby said hardware may be secured to the panel construction in slightly spaced relation thereto.

Still another `object of this invention is to provide hardware -attaching means of the type described in which the panel construction is provided with ay permanently disposed metallic socket member for receiving-a complementary portion of said hardware,

Fig.rl0 is a sectional view of the facing member panel construction shown in Fig. 3, illustrating a step in the construction of the hardware attaching means therefor.

Referring now more particularly to the drawings, there is shown in Fig. l a typical toilet stall 10 situated adjacent a wall 11, above a floor 12, andrbelow a curtain wall 13. This stall 10 is enclosed by partitions 14, facing members or stiles 15, anda swinging door 16. The door 16 is mounted for swinging movement from the rightmost facing member by hinges 17, and a door stop 18 is attached to the leftmost facing member for limiting the swinging of the door 16 outwardly of the stall.

Each of the facing members, partitions, and doors may comprise, as shown herein, a panel construction made up of threesheets 19 of opaque structural glass which are laminated together by a suitable mastic 20. However, this construction, although conventional, is not meant to b e a limitation on .the sc ope of this invention. To the contrary, each of the aforementioned members may be made of a single sheet of glass or, if desired, a pair of laminated sheets.

In any case, however, the panel construction making up the' facing members or stiles 15 is provided with through openings 21 (Figs. 2 and 3) or recessed open'- ings 22 (Fig. 4) for receiving the novel attaching means of this invention. If the panel constructions are formed.l of laminated glass sheets 19, as shown herein, matching holes are drilled through said sheets prior to thelamination thereo'f. In the case of the panel construction of Fig. 4, in which recessed openings 22 are formed therein, holes are drilled in only two of the sheets.

Dealing iirst with the hardware attaching means for the door hinges 17, the legs of a stirrup 23 of said hinge grip opposite sides of the facing member 15, asshown in Figs. 2 and 3. Each of the legs is provided with-op positely disposed `openings which are adapted to be 'substantially aligned with the spaced openings 21 in said facing members. Suitable hinging means (not shown) are disposed at the other ends of theV hinges 17 for at-v tachment to the door 16, but, for the purposes of illustration, only the details of the hinge attachment to the facing member 15 are shown herein.

In assembling one form of the hinge attaching means ofthis invention in the opening 21 through the facing member 15, a pair of opposed bushings 24,forming a socket member 24a, Figs. 2 and 8 are threaded onto the elongated stem 25 of a threaded bolt 26 and positioned within said opening, as shown in Fig. 8, while an enlarged head 27 o'n said bolt is held ush with the ad-v jacent surface of said facing member surrounding said opening. The stem 25 of the bolt as well as the length of the pair of bushings 24 are slightly longer than the depth of the opening 21 through the facing member 15 such that, when said bushings and bolt are positioned as shown, the upper ends thereof which arev oppo'site from the bolt head 27 project slightly above the upper surface of said'facing member.

` As shown in detail- 'n Fig. 5, one end of the bushing 24 is enlarged as at 28, for a purpose' to be explained hereinafter. A substantial length of the inner diameter of the bushing is -threaded for engagement 'with the threaded stem 25 of the bolt as well as to provide Athreaded Vsockets within the opening 21. Also, as best shown in Fig. 6, the venlarged head 27 on the bolt 26 is provided with a circular concentrically arranged rim 29 having an outer. diameter v.corresponding .tothat of `thi;

said head is held ush with y said rim. In this manner, when the bolt 26 and bushings t 24 are properly positioned within the openingV 21, as shown in Fig. 8, the lower end of the lowermost bushing as well as the portion of the stem adjacent the head 27 will project slightly below the under surface of the facing member 15. The amount of this projection, as well as that of the upper ends of the stem and uppermost bushing above the upper surfaceV of said facing member is preferably about 07.005 to 0.010 inch.

While the bushings and bolt are so held and positioned with respect to the facing member 1S, the entire assembly is placed face down on a plane support 30, as shown in Fig. 8, and suitable spacers 31 are disposed between said support and the facing member adjacent the head 27 so as to maintain said assembly in a substantially stable position. While the assembly Yis in this stable position, a filler material may be placed within the annular space in the opening 21 surrounding the bushings 24. For this purpose, I have found it desirable to use as a ller material a product known as Cerrobase composed of approximately 45% lead and 55% bismuth. This material has a melting point of approximately 255 F. and may be readily poured into the annular space about the bushings 24 at a temperature of about 485 F. It has` been found especially ywell-suited to applications of this type as it sets up or hardens rather quickly. y Y i Although the filler material will set up rather quickly, it will still completely fill the annular space surrounding the bushings 24 in the opening 21. In this manner, when said material hardens within said space, it forms an anchor 32 for permanently holding the bushings 24 in place. Portions of the anchor adjacent the bolt head 27 will project slightly below the lower surface of facing member 15 so as to surrround the similarly projecting portions of the lowermost bushing 24. As well, prior -to hardening, the upper surface of the filler material may be planed off even with the upwardly projecting portions of the -uppermost bushing 24. It will also be understood that the adjacent enlarged portions 28 of the bushings form additional anchoring means for retaining said bushings within the hardened filler material 32.

When the facing member I15, with its hardware attaching means now formed in the openings 21, is lifted from the support 30, the bolt 26 may be removed from the bushings 24 by means of the knurled surface 33 on the bolt head 27. With the bolt removed, the bushings form a socket within the facing member 15 having oppositely facing threaded openings which are adapted to receive bolts 34 (Fig. 2) for attaching thereto the stirrup 23 of the door hinge 17, or other article of hardware. Since the oppositely facing openings of said socket member project a slight distance beyond the adjacent outer surfaces of the facing member 15, the legs of said stirrup will be held slightly spaced from said surfaces, thus lessening the possibilities of undue pressure being applied thereto.

Dealing now with another form of this invention in which a door stop 18 is attached to the opposite facing member 15, it can be seen from Fig. 4 that the door stop is of an angular construction,` one flange of which is adapted vto be A secured to a hardware attaching means in said facing member. For this purpose, the flange 35 is provided with an opening which is adapted to be disposed in substantial alignment with the recessed opening 22 in the facing `member 15 4when the leg 36 of said'stopis in operative flush engagement with the edge of said member; shown. An oppositely disposed fiang'e 37 of the stop is adapted to engage the door 16 in itsclosed position.

Inasmuch as this type of hardware article is only attached lto one side of the facing member 15, the openings 22 for receiving the bushings 24 do not extend all the way through said member. Thus, holes may be drilled in only two of the glass sheets `19 and the smooth and uninterrupted finish of the opposite surface of the facing member is preserved.

This particular embodiment of the novel hardware attaching means of the present invention involves a slightly different assembly procedure. That is, only the two glass 4 sheets 19 which have been drilled are laminated together prior to the positioning of the hardware attaching means in the opening 22 formed by the holes in said sheets. When, however, these two rdrilled sheets have been laminated together, a bolt 26 (Fig. 6) having a single bushing 24 threaded over a short stem 2S thereof is positioned within the recessed opening 22, similarly to the manner in which the bolt 26 and bushings 24 of the earlier described embodiment were positioned within the through opening 21. That is, the single bushing 24 on the short stem 25 is centrally aligned within said opening by means of the rim 29 as the bolt head 27 is held flush against the facing member 15, as shown in Fig. 7. Also, the portion of the head 27 of the bolt 26 within the rim 29 is recessed to a depth slightly below that of the portion of said head surrounding the rim.

lIn this case, however, it will be noted that the stem 25 of the bolt 26' is considerably shorter than the stem 25 of bolt 26 and terminates short of the end of the bushing 24. As well, only a single bushing 24 is used with the enlarged portion 28 thereof disposed inwardly of the opening 22. It will be yfurther notedin this respect that, despite the differences in construction between the bolts 26 and 26', the bushings 24 may be used interchangeably with either of the disclosed embodiments of this invention. Of course, if desired, the bushing means forming the socket in the hardware attaching means of Fig. 2 may comprise a single integral bushing, rather than a pair of the interchangeable bushings 24.

When the bushing 24 and bolt 26' have been so positioned with respect to the opening 22, the two sheets 19 of the facing member 15 and said assembled bushing and bolt are placed face down on the support 30, simi- Vlarly to the manner in which the facing member and hinge member attaching means of Fig. 8 were placed on a similar support. As shown'in Fig. 7, a spacer 31 may be used adjacent the enlarged head 27 of the bolt for stabilizing the facing member in its supported position.v

At this time, Cerrobase or other suitable filler material may be poured into the annular space Within the recessed opening 22 surrounding the bushing 24 as well as above the enlarged portion 28 of said bushing to at least approximately the level of the top of the uppermost glass sheet 19. When `the ller material has hardened to form an anchor 38 and while the facing member 15 is still resting'upon the support 30, the top sheet of glass 19 (shown in phantom in Fig. 7) is laminated to the middle sheet by means of the mastic 20.

Thus, the facing member 15 is completely formed with its hardware attaching means and may be lifted from the support 30. The bolt 26' is then removed from the bushing 24 to form a relatively short threaded socket in the facing member, which socket is adapted to receive a threaded bolt 39 forsecuring the door stop 18 to the hardware attaching means formed in said facing member, as shown in Fig. 3. Also, similarly to the stirrup 23 of the door hinge attaching means of Fig. 2, the ange 35 of the stop 18 is held `in slightly spaced relation to the adjacent surface of the facing member 15 (as shown in Fig. 4) by means of the projecting opening of the socket. A

ln Fig. 3, the door hinge 17 is shown as attached to the facing member 15 by still another form of this invention in which the bushings used in connection with the previously described forms are dispensed with and a stem 40 of a headed bolt 41 (Fig. 9) acts as the socketz forming member.

Referring specifically to Figs. 9 and l0, it can be seen that the bolt 41 includes, similarly to the bolts 26 and 26', an enlarged head 42 having a knurled outer periphery 43 and a concentrically arranged rim 44 for centrally aligning the stem 40 within the opening 21 through the facing member 15. As well, the portion of said bolt head 42 within the rim 44 and surrounding the base of the stem 40 is recessed to a depth about 0.005 to 0.010 inch below the level of the portion of said head surrounding the rim.

The stem 40 is very slightly tapered toward its upper end, for a purpose to be explained hereinafter, and is of a length slightly greater than the depth of the opening 21 such that the upper end of said stem will project slightly above the upper surface of the facing member 15 when the bolt 41 is held in its centrally aligned position within said opening. The assembled facing member and bolt may be placed upon the support 30 and Cerrobase or other suitable material may be poured into the annular spacing surrounding the stem 40 within the opening 21.' As in the case of the other forms of this invention, the filler material will entirely fill said space so that the portion thereof disposed above the recessed portion of the bolt head 42 within the rim 44 will project outwardly about 0.005 to 0.010 inch beyond the lower surface of the facing member 15. As well, prior to hardening, the ller material may be leveled off adjacent the upper end of the stem 40 to a plane approximately aligned therewith so as to form a similarly projecting portion about said upper end of the stem.

Due to the slight taper of its stem 40, the bolt 41 may be removed with minor effort from the bushing 45 formed by the hardened filler material within the opening 21. That is, upon a slightly forced turning Yof the bolt head 42, the stem 40 will be freed from the bushing 45 and may thus be pulled therefrom.

The stirrup 23 of the hinge 17 may at this time be properly positioned over the edge of the facing member 15 with the legs of said stirrup held in slightly spaced relation to the surface of said facing member by means of the projecting openings at opposite ends of the socket formed in the bushing 45. The legs of the stirrup are secured to this form of the novel attaching means by bolts 46 received through said socket and held by nuts 47. Of course, the threaded bolts 46 are received in slightly spaced relation to the socket formed in the bushing 45.

It will be obvious that this type of attaching means, in which the filler material itself forms the socket for securing the hardware thereto, may be also used in connection with the door stop 18. In such a case, of course, the stem of the bolt 41 used in forming the bushing 45 within a recessed opening 22 would be shorter. Also, if desired, the door stop 18 could be secured to the Cil socket formed in the bushing 45 by means of a selfthreading screw (not shown), rather than by the bolt 46 and nut 47.

It is to be understood that the forms of the invention disclosed herein are to be taken as the preferred embodiments thereof, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the following claim.

-I claim:
