APPARATUS FOR APPLYING WATERPROOF BANDS FOR `GLAZING AND THE LIKE Filed Feb. l0, 1932 5 Sheets-Sheet 5 www Patented pr. 3, 1934 APPARATUS FOR APPLYING WATERPROOF BANDS FOR GLAZING AND THE LIKE Lon Joseph Sagit, Paris, France, assignor to Paix & Cie, Douai, Nord, France, a French Company Application February 10, 1932, Serial No. 592,091 In France March 17, 1931 6 Claims.

In the construction of glazed roofs (sheds) for instance, in order to obtain a waterproof joint between the glass panes and their supports or frames, it is known to cover the joint with a waterproof band consisting of cloth or other bands coated with layers of bitumen or analogous material. Hitherto such bands have been put in place by hand. The band is rst softened by heating it by means of a soldering lamp or a blowpipe, and the workman then applies the band by hand, causing it to assume the proper shape by pressing it with the ngers. For this reason, the work is long and expensive, and the appearance is unattractive, especially when the bitumen melts by an excessive heating and thus flows upon the glass panes.

In other cases, bands are applied by the use of an adhesive substance which is coated on by a brush according as the band is applied.

The present invention relates to an apparatus for applying waterproof bands for glazing and analogous Works, which is chiey characterized by the fact that it comprises one or more bending members xed or rotatable, of a suitable 25 shape, and assuming such positions that the band will be properly bent and applied against the surfaces of the support such as a T-iron bar or the like.

According to another feature, the apparatus comprises a roller or a similar member which serves to support the band and which is mounted infront of the said bending members in the directionoi travel of the apparatus and is adapted to form in said band an inclined sheet which may be readily heated or coated with an adhesive substance before it is applied.

In the accompanying drawings which are given by way of example:

Fig. 1 is an elevational view of the apparatus,

Fig.` 2 is a section on the line 2-2 of Fig. l,

Fig. 3 is a sectional end View of the apparatus,

Fig. 4 is a partial section on the line 4-4 of Fig. 2,

Fig. 5 is an end view or a bending member, according to another construction,

Fig. 6 is a front View of the same,

Fig. 7 is a section on the line 7--7 of Fig. 6.

In the form of construction shown in Figs. 1 to 4, the apparatus consists oi a frame 1 upon which is mounted a curved member 2, screwed to said frame or formed in one therewith; in the middle of said curved member is situated a rod 3 upon which is tted a handle 4.

The frame l rests upon two tubes 5 formed in one with the frame. At respective ends of said (Cl. Iii-3.5)

tubes are mounted two screws 6 (or like adjustable device) whose heads rest directly upon the glass panes 7. Two cylindrical arms 8 extend forwardly of the frame 1.

Below the said frame are situated two bending members, such as rollers 9, having a suitable form so as to fit into the angle between the web of the T-iron bar 10 (or the like) supporting the glass panes "l, and the panes themselves. Each roller is mounted on an axle 11 which is screwed into 65 one of the bossages l2 of the said frame; the rollers are held upon their axles l1 by a respective wing nut 13 screwed upon a threaded sleeve 14, or by like means.

The two axes 11 intersect, the angle Z between 70 them (Fig. 2) being of 90 degrees in the present example; this angle may obviously vary according to the shape of the iron bar or other support.

Preferably, every axle is not situated in a transverse plane, such as the plane of Fig. 2. It is inclined from this plane by a small angle y (Fig. l) which may for instance be 5 degrees, the inclination being directed upwardly from front to rear of. the plane of Fig. 2.

The cylindrical arms 8 (Fig. 1) carry two collars 15 which may be secured to the said arms by a set-screw 16. At the top of said collars is mounted a threaded pin 17.

A roller 18 of suitable shape is screwed to the central part of the pin 17 and is held in` this position by a pair of lock-nuts 19. On either side of the roller 18, a respective end-plate 20 is screwed to the pin 17. Each plate is held in position by a lock-nut 2l for example. On the smooth parts 22 of the threaded pin are pivotally mounted two arms 23. At their opposite ends, the said arms 23 (Figs. 1 and 2) are screwed to the two threaded ends 24 o1" the smooth axle 25.

This axle 25 connected by springs 26 with the frame l, carries at its middle part a roller` 27v held in place for instance by two rings 28 fastened by pins. On either side of the roller 27, the axle 28 carries two respective end-plates 29 whose lower ends are adapted to rest upon the frame l, and whose position can be adjusted by two set-screws 30, or otherwise.

On the ends of the arms 8 (Fig. 1) are mounted collars 3l. whose position can be adjusted by setscrews 32 or otherwise. The collars carry a roller 33 which is pivotally mounted on the axle 34. This roller is grooved so as to roll upon the web oi the T-iron bar 10.

To one of the arms 8 is secured in any suitable manner, for instance by an upright 35 and a collar 38 a receptacle 37 (Fig. 3). This receptacle is provided at the top with a pressure pump 38 and is connected by a tube 39 fitted with a cock 40 with one or more blow-pipes 41 which can be regulated by milled wheels 42. The blowpipe or blowpipes are held by a collar 43 secured to the receptacle 37. The said receptacle can be removed by means of a handle 44 secured to the same.

The operation is as follows: The apparatus is placed upon the glass panes 7 by means of the tubes 5, and the roller 33 rests 'at 4the front part upon the web of the T-iron bar 10. The end of a waterproofing band is inserted into the appa ratus in the followingl manner. The end-plates r 29 are first adjusted according to the width of the band in use. These plates are then fixed upon the axle 25 by the set-screws 30. The same operation is performed for the end-plates 20. The band is then inserted below the stretching roller 27 (Figure 4), after that upon the intermediate roller 18. The band 13 is then brought between the rollers 9.

The apparatus is moved forward in the direction of the arrow f while pressing downwards upon the handle e.

The band thus travels forward, and is accurately applied to the supporting bar 10 and to the glass pane 7, by means of the bending rollers 9. Each roller 9 commences to act upon the band at a point A and leaves it at a point A. Due to the inclination y ofthe axle 11, the roller 9 exercises a transverse 'traction upon the band during the whole of this period, and thus the band is exactly fitted to the supporting bar i0 and to the glass pane 7.

The roller 27 which presses upon the band permits to exercise a practically constant force upon the apparatus for the forward feed, irrespectively of the physical state of the band (whether more or less soft according to the temperature), and also to exercise a practically constant force in the direction of the arrow f-, due to the weight of the remainder oi' the band to be applied, or to the resistance of the band to the forward travel.

In fact, according to the said force or to the physical state of the band, the roller 27 will rise more or less against the action of springs 26, whereby the length of the curved part will be varied.

If a band impregnated with a bituminous substance or the like is employed, this band is softened by the flame of the blcwpipe or blowpipes.

Figs. 5 to 7 show a modified forni the inembers used for the bending of the said band, and herein the member adapted for the bending of the band in order to apply it upon the inverted T-iron bar 10, or the like, consists of a metallic sheath 5l having a LI-shaped cross-section, and its external and internal outline abcdef (Fig. 7) corresponds practically to the very section of the bar 10 which is to be covered. The inner edges 52 are preferably bevelled or rounded at the front part where the band enters, as shown in Fig. 5, so as to afford a gradual bending action upon the band 50.

The sheath 51 may consist of lead or other suitable metal, latter being preferably of a sufficiently plastic nature to avoid damage to the band.

The said sheath 5l may be properly secured to any support, for instance to the frame 1.

The fastening may be realized for instance by holding the sheath 51 in a support 5S consisting of cast or wrought iron, or like metal. The

sheath will be provided with lugs or analogous parts 54 by which it may be secured to the support.

The sheath 51 provided with its holder or support 54 may be substituted for the rollers 9, or it may be used in the same apparatus in combination with these rollers.

The aforesaid apparatus is well adapted for bands which are thin or very pliable, but which will not be softened to such a degree that they will be torn ofl' when put in place.

The blowpipes 41 may be replaced by a spraying device by which an adhesive substance is supplied to the band.

As will be observed, the said apparatus affords lthe approved results, and the band is applied at a much higher rate than usual, this being at least ten times the customary speed.

Obviously, the present invention is not limited to the forms of construction herein described and represented, these being given solely by way of example.
