Figure isv a transverse section taken 4substantially on line 5-A-5 of Figure 1, but illustrating a slightly modified form of saddle. t t t Referring speciically to the drawings the numeral 5 designates anA elongated metallic strap that is bent at ya right angle at its lower end to form a foot portion 6 wherein the 4concretelintel iswto be poured-and whereby to'accurately position the saddle at predetermined points for reception of the rafters or joists and with the saddle being-connected to an anchor strap that projects above and below the saddle and whereby the lower end will .be supported` in a position to be anchored within the` concrete to be poured within the formY and with the upper end `of the strap Abeing -apertured at spaced apart points for nailing engagement or bending engagement with the oorfjoists or rafters to be secured.

The invention contemplates an lanchoring and seating device that includes `a saddle and an anchoring strap and withthe saddle atits opposite ends being inwardly slotted ,forthe reception of securing, nails whereby the s addle will span the distance between form boards constituting that is to be embedded within the concrete of a lintel to be poured. The upper portion of the strap 5 is aper-Y tured -at spaced apart points as at 7 to provide nail holes whereby the strap may be nailed to the sides of oor joists, roof rafters or therlike. Substantially intermediate the length of the strap 5, there has been pivotally supported as at 8 a channeled saddle 9. The saddle- 9 is upwardly opening and its opposite ends areangular-ly projected as at 10for overlyingengagement with form boards 11 that constitute the formsor a lintel12, of poured concrete. The angularly disposed ends 10Y are notched as at 13 for the passage of Vnails 14 that are employed to temporarily support the saddle in supporting engagement upon the upper edges of the boards 11 during the pouring of the concrete. The saddle 9 has `a transverse width capable of receivingV a conventional wood beam that constitutes the ioor joistor the roof rafter. The form boards are supported against the Vopposite sides of a preformed Yand prefer-ably concrete 1 block wall 14 to project thereabove a distance correspondthe mold and with the form boards being subsequently plate Varound the vlintel to which is connected in various ways the rafters or joists and it is the purpose of this device to form a saddle and an' anchoring strap in a l sinliplegand-expeditious manner, `completely eliminating the wbodplte 'and'resulting in ai` very considerable savving in material and labor.

Novel features of construction and operation of the device will be more clearly apparent during the course of the following description, reference being had to the accompanying drawings wherein has been illustrated a preferred form of the device and wherein like characters of reference are employed to denote like parts throughout the several figures.

In the drawings:

Figure 1 is a perspective View of a tie-down device constructed in accordance with the invention,

Figure 2 is a transverse section taken through the upper portion of a preformed block wall having form boards disposed upon the inner and outer sides thereof and with the form boards projecting upwardly above the wall a distance vcorresponding to the depth of the lintel to be cast and showing the invention in operative relation thereto,

Figure 3 is a fragmentary top plan view of the structure of Figure 2,

Figure 4 is a fragmentary longitudinal section taken on line 4-4 of Figure 2., and

ing to the depth of the lintel to be poured. Thus the saddle will be supported in -a position defining the top plane of the lintel. Y

In the form of the invention illustrated in Figure 5, the saddle is provided with al double ventilated bottom wall v15 wherein air passages 16 are provided throughout the length of the saddle to prevent the passage of moisture to the beam that is being anchored. In this form of the invention, the saddle is preferably extruded from metal to provide the multiple air passages.

In the use of the device, the form boards 11 are positioned against the inner and outer sides of the wa-ll 14 and clamped thereto in any well known manner.V It then being determined the proper spacing of the oor joists `or rafters, the saddles and their connected straps are positioned on the top of the form boards in the position where the rafter or oor joist will normally rest. Nails 14' are then driven into the formboards through the. notches 13 Vand Aanchors the saddle in -a correct position of alignment for receivingthe rafters or joists. With Ythe saddle nailed in position, the strap 5 will be accurately `spacedintermediate thewidth of the form` and with the -lower portion depending into the form, with theflegs 6 in spaced v'relation to Ytheetop of the wall 14. Concrete is then poured into the form to the level of the upper edges of the form boards and the bottoms of the saddles. When the concrete has suiciently set, the form boards may be stripped away, pulling the nails out of the notches 13, and leaving the saddles securely held upon therupper side of the lintel 12 and with the strap 5 securely anchored into the concrete. The rafters or floor joists are then laid in a conventional manner and with their ends being disposed within the saddles. The upper portion of the strap 5 is then nailed to the adjacent sides of the rafters or joists and if desired, the strap may be bent over a rafter or a oorjoist after nailing to avoid cutting the extended end thereof.

It will be apparent 4from the foregoing that a very simple and highly eiiicient anchoring means has been provided for floor joists and roof rafters. The device is quicklyinstalled with a minimum of effort and in accurate spacing' relation to each other and forms a denite saddle for the resting support of the ends of the floor joists or rafters. 'Ihe use of the device -avoids the relatively expensive use of wood plates and the labor necessary in rst installing anchor bolts, then drilling the plate Patented Aug. 2, 196@V in order to engageover the several bolts that project above the lintel 4Diiliculty has been experienced with the use of anchor'bolts, sinee it becomes necessary that theanchor bolts be' forced into the poured concrete prior to'the settingzthereof Vand it'becomes diiicultto properly positionithe bolts'and maintain them liiralignment for subsequent bolting engagementjwith the wood plate. Thedevice results-in avery consider-ablesaving inlabor and presents an extremely novel `and effective tie-'down vdevice for buildingstructures. Asfbefore'stated the slotted ends of the saddle .permit thestripping away of the form boards without the necessity of withdrawing the nails 1f4.

` It is to'be understood that the inventionr is not limited to the precise arrangementshown, but that changes vare contemplated as readily fall-within the spirit of the invention as shall be Idetermined by' the scope of ythersubjoined claims.
