Jan 6, 1931. D. J. FINUCANE LEADER PIPE STRAP 1 Filed Sept. 6. 1928 all:

ATTORNEYS Patented Jan. 6, 1931 I PATENT ()FFICE DANIEL J. IINUCANE, OF BROOKLYN, NEW YORK LEADER-PIPE STRAP Application filed September This invention relates to straps or hands adapt-old for use in the attachment of waterconductor or leader-pipes to the walls of buildings and is in the nature of an improvement upon the invention disclosed in Letters Patent of the United States Number 1,676,485, granted to me on J uly 10, 1928.

Leader-pipes, in accordance with a practice widely followed, are supported by placing the sides thereof between the arms of a U-shaped staple or bracket having a central prong adapted to be driven into the wall. A Wire attached to the outer ends of the staple arms and spanning the front surface of the leader-pipe holds the latterin its position in the staple. In'order to conceal the staple and wire, a metal band which embraces the front and sides of the leader-pipeis then i the wall of the building.

ferred to above, disclosure is-made of a band yet adaptable placed over the fasteningwith end portions of the bands folded outward to lie flat against In my patent reof thecharacter indicated and suitable for this purpose, said band comprising embossed ornamental. ends and successive body portions having reinforcements embossed therein, the body portions being separated from one another and fromthe ornamentalends by bending zones adapting the strap to be a bent into conformity with the leader-pipe and with the wall of the building. These features are also utilized in the illustrative embodiment of the present invention.

It'is an object of. the present invention to a provide a strap capable of effecting a more complete concealment of the leader-pipe supporting staple and wire than heretofore, and to installations varying through a considerable range.

It is a further object to provide a construction in which the end and body portions are a more rigid than heretofore and in which the bends between the side body portions and the ends of the strap are adapted to be more sharply defined so that the body portions and ends maynot merge through a curved portionof large radius but be each in its separate plane. Because of these features the strap is adapted to grip the pipe more securely than the prior construction and to 6, 1928. Serial No. 304,211.

serve more effectively as a support for the pipe, whether used in conjunction with the staple or other spacer or used separately for gripping the pipe directly against the wall.

Leader-pipes are generally standardized so that a line of supporting straps suitable for all usual installations may be confined to a small number of standard sizes so far as the requirements imposed by variation in leader-pipe dimensions are concerned.

It is common practice, however, for architects to specify that the leader-pipe be supported at a distance outward from the wall of the building, such installation being in some cases necessitated by irregularities in the face of the building and in other cases considered desirable for other reasons. Such spacing requirements on different jobs vary considerably. It is, accordingly, an important aim of the present invention to provide a strap which is adaptable to all usual spacing requirements and which therefore can be made in one standard size for a given size of leader-pipe.

It is a further object of the invention to provide flanges along the edges of the strap in order that a housing or boxing may be formed when the strap is bent into conformity with the leader-pipe to completely conceal the staple and wire. Such flanges are designed to extend continuously throughout the length of the strap except at the particular points at which bending is desired, and therefore cause the bends to be sharply delined and prevent deformation elsewhere than at the lines of bending.

Other features of the invention relate to the cutting of these flange-s in the bending zones between the side and end portions, and to the offsetting of adjacent ends of the flange sections between the front and side body portions so that the flanges will be situated in such relation to one another that they will not interfere with the desired bending of the strap. I

- Otherobjects and advantages will hereinafter appear. 7

In the drawings forming part of this specification,

Figure 1 is a plan view partly in section and partly broken away, showing a leader-pipe supported on a wall and surrounded by a strap embodying features of the invention;

' Figure 2 is a view similar to Figure 1 showing anv identical strap applied to another installation in which the spacing requirements are'different from those of Figure 1 Figure 8 is a fragmentary verticalsectional view through a leader-pipe and the support-Q ingstrap of Figures land 2 I 4 7 2 Figure 4 is an edge view of a strap of "the kind disclosed in Figure 1 showing .the strap in the form in which it'is received on the job;and p F igure. 5 is a plan Viewof the strap shown in Figuren L, I In Figurel aaleader pi peil is: shown snippor'ted from a building wall 2 by means a U-shaped bracket 3 'havinga central driving prong-N4 penetrating the wall. 'TIhe-leaderpipe is bound to the bracketby a wire 5 passed around the front. fac'e 'of the :leaderpipe and wrapped-at its'ends'around hooked ends 6 at the outer ends of arms? of the bracket "3. It will be observed ,that the bracket 3 does not have its shank 4 driven completely into the Wall but that it is spaced outward arshort distancefromzthe wall; The leader-pipe itselfmay be regarded, as one of standard size. 2 y

. The bracket, 3 and-wire 5-are concealed and substantially housed by a facing strap 8.

Such strap comprises flangedend portions 9 having ornamental-embossments 10 formed therein. Su-chstrap further comprises 'acentralbody portion 11 and side body :portions 12 and 1-3 which body'portions have reinforcing embossment-s 14:, 15, and 16, formed in their respective faces. The central body .por

tion 11 is provided with side flanges 17 :and

' the side bodyportions l2-and 13 areprovided with side flanges 18 and 19 respectively. These flangesarea'dapted-to form upper and lower housing walls and to engage the front and side faces of the leader-pipe when the strap is bent into conformity with theleaderpipe. Intermediate thecentral body portion 11 and the side body portions -12 and 13. the reinforcing enibossments are omitted-so'that flexible bending z'onesare provided to facil-i: tate application of the-strap to the leaderpipe. At the bending'zone 20-the flanges 17 are separated from the flanges 18 and at the bending zone 21 the flanges 1-7 are separated from-the flanges 19. Inbrderth-at'the flanges shall not interfere with "bending of the strap the inner ends of fiange s-1'8' and :19 are'formedrwith offsets -22and 23 to disalign them with respect'tothe flangesili'. x

It will be seen from a comparisonof 'Figures 1 and 2 thatineifectingdifferentinstallati'ons, it will be. necessaryto bend outward the ornamental end :lportions of the strap at different points. In order to-enable this to be done, orovision is. made "between the bodyportion 12 and one end portion 9 of an unembossed bending portion 2 1 and between body portion 13 and the opposite end portion 9 of an unembossed bending, portion 25. These bending portions 24 and 25 are made of substantial length suflicient to accommodatejall' of the variations ordinarily encountered in the spacingof leader-pipes outward from walls. As seen in Figure 1, for

example the leader pipe is located fairly close to the "wall and the strap is bent in portions ofthe bending zones 24 and 25 closely adjacent to the body portions 12 and 13. In Fig ure 2 on the otherhand, the leader-pipe is spaced a substantial distance outward from therwall-and the bending ispeflectcd in the bending zones 24,.and 25, at points'fclosely adjacent to the ornamental end portions9.

In order to effect this bending, the workman determines by measurement the locations inthe bending zones at which the bending is required by the particular. leader-pipein- 'stallation onwhich he is working and then cuts through the flanges 18 and 19 in the appropriate portions 0f the bending zone for permitting the bends to be formed at-the de sired points. The strap is then bent into the shape shown in Figure 1 or 2 and is either soldered to the leader-pipe or secured in place by nails 26 driven into the wall ofthe building. If desirecLit may be bothsoldered 'to the leader-pipe and nailed to the wall, to assist in supporting the leader pipe in place.

It will be-seen that thezflanges 18 and 19 should preferably be cut inorder to permit bending in thebending. zones 24 and 25 and that when so 'cutT'the bending is confined :in

each zone to 'a :line joining the cuts. 'The bends will, therefore, be:sharply defined so that theproduotion of :a neat, attractive,

workmanlike job will result asa'mat'ter of 2 course.

' WVhile I have illustrated and described in detail certain preferred forms of my invention, it is to beunderstood-lthat changes may be made therein andthe invention embodied in other structures. I do not, therefore, desire to limit :myself to the specific constructions illustrated, but intend to cover my invention broadly in whatever form its principle may be utilized.
