12 Claims.

This invention relates to glazierspoints and particularly to a glaziers point for use in'the construction of the sloping roofs of hothouses, nurseries and similar structures.

In constructing sloping glass roofs for buildings of the kind mentioned above, it is customary to provide a series of parallel strips, corresponding to the rafters of a frame building, each extending from a ridge pole obliquely downward to a-horizontal frame member extending parallel to the ridge pole. The upper edges of these oblique parallel strips are rabbetted and glass panes are laid along in the rabbets in overlapping relationship in the manner of shingles. The parallel oblique strips provide the sole structural support for the glass panes.

In mounting the glass panes it is thus necessary to provide means which prevent lifting of the panes from their seat and also to prevent the panes from sliding downwardly along the supporting strips. Many devices have been pro posed in the prior art for" effecting these two ends, but none have been commercially successful and it is the usual practice in the practical art to drive brads into the strips at, opposite sides of the pane above the glass and to drive other brads into the strips at opposite sides of thepane immediately below the lower edge of each pane to prevent downward sliding movement.

Prior art fastening devices proposed to accomplish this dual purpose have either been inadequate from the standpoint of rigid securement or have been of such nature as to require right and left-hand fastening devices at opposite sides of the pane or have been subject to both infirmities; In any event, despite the eifcrts of priorinventors to provide a satisfactory securing device the accepted commercial practice at the present time is the brad method described in the preceding paragraph.

According to the present invention, a fastener is' provided which adequately and firmly restrains the panes both against any lifting move,- ment and against any downward sliding movement. Further, fastening devices constructed according to the present invention may be used either left or right-hand interchangeably. The nature of building constructions of this kind and the numerous fasteners required in constructing a hothouse or nursery, render it practically out of the question to employ fasteners which must be furnished and selectively usedeither right or left-hand only. Further, the fasteners of, the present invention may be manufactured in mass production either entirely by stamping from sheet metal or by a combination of extrusion and stamping, whereby production of the fastening devices may be accomplished at a cost which renders their use commercially attractive.

Many other objects and advantages will occur to thoseskilled in the arts concerned from a study of the formsof .my invention shown by way of example in the accompanying drawing and described in detail in the following specification. It is to be understood, however, that the scope of the invention is not limited to the precise forms shown by way'of example nor otherwise than as defined in the appended claims.

In the drawing:

Fig. l is a fragmentary perspective View of a portion of a hothouse or nursery roof employing one form of the fastening device of the present invention;

Fig. 2 is a detailed perspective view of the form of fastener illustrated in Fig. 1; and

Fig. 3 is a detailed perspective view of a modified form of fastener,

In the several figures of the drawing like characters of reference denote like parts and, referring to Fig. 1, the numerals l0 and H designate a pair of parallel slanting strips having their opposite upper edges rabbeted to receive the edges of glass panes as at I2, i3 and I4. In.Fig. 1 the numeral 15 designates a glass pane which seats in the rabbeted edges of strips II] and I l and overlaps the next subjacent pane I3. Pane I5 is held. securely, both against a lifting movement from its seat in the rabbets and against downward sliding movement, by means of a pair 7 of identical fasteners designated generally ll. One of the fasteners H is shown in detail in Fig. 2 and comprises a flat oblong base portion 26, a downward flange 2|, and lateral projections 2?. and 23 at the end opposite downward flange 2i. Projections-22 and 23 preferably lie in plane of body portion 20 and are pointed so that they may readilybe driven into wood or the like. Downward flange 2! also has pointed

lateral projections

24 and 25 which lie in a plane at right angles tov the projections Hand 23.

Body portion 20 is provided with a medial vertical flange 26 upon. its upper surface. The fastener I1 is driven to its assembled positions at opposite sides of pane [5 as shown in Fig. l by hammering against flange 26. The efficacy of the fastener of the present invention is enhanced by reason of the fact-that the opposite side edges of the body portion 20 abut the sidesurfaces .oftherabbetsof stripsv l0 and II when the fastener is driven home. This insures that all fasteners be driven in an optimum amount, neither too much nor too little. It further insures proper ultimate alignment of all of the fasteners. If a careless workman should drive the fastener so that one or the other of its projections is fully driven before the other, further hammering will drive the other projection home and square up the fastener.

It will be noted that, in the case of the lefthand fastener I! of Fig. 1,

projection

22 and 24 comprise the nailing portions. In such case the

projections

23 and 25 serve a useful purpose since they extend the bearing surface of the fastener over pane l to insure adequate holding. This may be particularly important where the immediate corner of a pane is chipped or broken, so that it might not otherwise be held.

The form of the fastener of Fig. 2 i such that it lends itself readily to mass production. One manner of producing the device is to use as a starting material a continuous extruded bar of T cross section, the stem of the T comprising flange 26 in the final product. The stem of the T may first be notched to form individual flanges 26 along the bar and the bar may then be blanked or notched and subsequently flanged, all in a manner which is common in conventional sheet metal fabrication.

The modified form of fastener illustrated in Fig. 3 is such that it may be fabricated entirely from sheet metal according to conventional practices. This form of fastener comprises a central oblong body portion 30 having a pair of upturned hammering flanges 3| and 32 along its opposite longitudinal edges. Hammering flanges 3! and 32 also serve as depth gauges as previously described in connection with the fastener of Figs. 1

and 2.

The fastener of Fig. 3 likewise includes a downward flange 34 having lateral

pointed nailing extensions

35 and 36 and at its opposite end the body portion 30 has a pair of lateral pointed nailing extensions 38 and 39 lying in the same plane as body portion 39. The manner in which the fastener of Fig. 3 is employed is identical with that of the fastener of Figs. 1 and 2.
