The object of my invention is to provide a novel form of saddle and fascia plate and fascia plate connections, and also a method of grouting under the metal to secure the same, so that these parts may be accurately positioned and easily inserted. These and other objects are accomplished by my invention, one embodiment of which is hereinafter more particularly set forth.

For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which Figure 1 is a longitudinal section of an elevator shaft embodying my invention, the bottom showing the saddle grouted and in place, and the upper view showing the saddle ready for grouting, except for an end form board to keep the grouting in place;

Figure 2 is a plan View of a saddle;

Figure 3 is a front elevation of a fascia plate;

Figure 4 shows an end view of a saddle supported by a bracket;

Figures 5 and 6 are side elevations and front views respectively of a spacer and holder for the lower edge of the fascia plate;

Figure '7 shows a bolt and end of a saddle and a portion of a bracket together with a plate shown in perspective in Figure 8.

Throughout the various views of the drawings, similar reference characters designate similar parts.

An elevator well has doors between parts of the frame of a building such as I-beams 1 supported at any suitable level. Each elevator door 2 func-- tions in the conventional manner opposite a doorway 3, which has the usual trim 4. All of these are conventional and form no part or" my improvement.

Each door sill is called a saddle and is designated by the character 5. In each saddle is the usual guiding groove 6 on its upper surface, and on its lower surface is a second groove 7 which runs longitudinally from one side flange 8 to the other and in this groove is placed a rod 9 on which is pivotally mounted an inner fascia plate 10 which remains permanently in place and holds grouting 11 under the saddle until the same has hardened.

This grouting l1 rests on the ordinary concrete 12 which is placed about the beams 1 in the conventional manner. Before the grouting is inserted, each saddle 5 is supported by

brackets

13, 14 and 15, which are alike, so that a description of one will answer for all. Each bracket has a horizontal base 16 and a slotted upright 17 with teeth 18 on each side of each slot, over which rides a washer 19 with a horizontal and a vertical flange 20 and a central slot 21, as shown in Figure 8. The purpose of these flanges 20 is to guide the washer with regard to the teeth 18, and give a suitable bearing for a head 22 of a bolt 23, which passes through the flanges 8 and holds the saddle 5 at a proper elevation. As the saddle 5 is larger at one end than at the other, and reduced at the middle, it is advisable to use three of these brackets. Each base 16 has a longitudinal slot 24, through which passes a bolt 25 for holding the bracket in place prior to the grouting.

A hook wire 26 (see Figure 1) extends from the rear of the bracket to the front of the inner fascia plate 10 to hold the same, when the grout is poured.

It is obvious that forms of some sort must be used to confine the grout within proper limits at the ends of the fascia plate 10 and about the

brackets

13, 14 and 15, but as these are conventional, no further description is necessary. Enough has been said to showthat the saddles may be set true and without difliculty prior to the grouting, and thereafter the grout may be inserted to secure them in place. If the forms are placed beyond the support brackets, these brackets may be also grouted in place and securely held, because they will be firmlyembedded in the concrete of the building.

The saddle 5 carries no outer nose or anything 35 of that kind, but has a front edge 27 perforated at each end to receive a screw 28, as a thumb screw, which may be mounted so as to pass through a washer 29 below its head, and the lower end of this screw 28 passes through a bar 90 30 which runs parallel to the edge 27 and supports the outer fascia plate 31 which is bent, as shown in Figure 1, so as to be held by this bar 30. The lower end of this outer fascia plate 31 is bent upwardly and inwardly as shown at 32 to engage and downwardly project the end of an adjustable spacer 33, and be pressed against a vertical extension 34 which projects upwardly from a laterally extending portion 35 of the metal trim 4 of the door-way 3.

The spacer 33 has several peculiar elements which will now be described, particular reference being had to Figures 5 and 6.

The lower end of the spacer has a shank 36 which takes back of the trim 4 and is embedded 105 in the concrete of the building, and this extends upwardly to a point 37 and then laterally at 38 to form a projection against the vertical part 34 and then is bent back on itself at 39 for an inch or so, and thence upwardly at 40 to form a vertical web 41, and at its top, this web is divided into three parts, two of which, 42, and 43, project forward so as to engage the lower edge of the fascia plate 31 above the hook 32, and the third part 44 is bent to form a U projecting laterally and downwardly so as to come over the upper end of the hook 32. For the purposes of adjustment, a thumb screw or other suitable device 45 passes through the web 41 and has a screw-threaded engagement with the part 44, so that the lower edge of the part 44 may be suitably adjusted to fit snug against the fascia plate 31 before it is elevated into place by the bar 30 which is raised by turning the screws 28.

In View of the foregoing, it is obvious that the inner fascia plate, together with the forms which are used, keeps the grout in position and the

end brackets

13, 14 and 15 hold the saddle true prior to, during and after grouting, so that the saddles may be laid with absolute certainty and with a minimum amount of labor.

Furthermore, as the grout is kept in proper bounds, there is nothing to interfere with the subsequent operations incidental to placing the outer fascia plate in position. The outer fascia plate is readily inserted without any difficulty in the registration of screw holes, and with a reasonable latitude of vertical adjustment, so that it may be placed with facility and accuracy.

While I have shown and described one embodiment of my invention, it is obvious that it is not restricted thereto, but that it is broad enough to cover all structures that come within the scope of the annexed claims.

Having thus described my invention, what I claim is:

1. A saddle and two fascia plates secured thereto, an inner one adapted to facilitate grouting and an outer one to cover the masonry of the building.

2. A saddle, brackets for supporting the said saddle, an inner fascia plate hung from the saddle, and a hook securing the fascia plate and saddle in proper relation for grouting.

3. A spacer for the lower edges of fascia plates, provided with a downwardly extending shank adapted to be held against the masonry of a building by the metal trim thereof, a laterally extending part adapted to abut against said trim, an upwardly extending portion with a part adapted to engage the vertical part of a fascia plate, and an upwardly and downwardly extending portion adapted to engage a hook of a fascia plate.

4. The substance of claim 3, when limited to an adjusting screw for positioning the hook engaging part.

5. In a construction of the class described, the

combination with several spaced slotted brackets of a support on which the brackets are secured, a saddle supported between the brackets, means for holding the saddle at a desired position in the brackets so that a space exists between the saddle and the support, a plate hingedly attached to the bottom of the saddle and dependent therefrom, and means projecting inwardly from the plate and engaging the brackets to cause said plate to close one end of the space between the saddle and the support and hold grout in said space.

6. In a construction of the class described, the combination with several spaced slotted brackets of a support on which the brackets are secured, a saddle supported between the brackets, means for holding the saddle at a desired position in the brackets so that a space exists between the saddle and the support, a plate hingedly attached to the bottom of the saddle and dependent therefrom, means projecting inwardly from the plate and engaging the brackets to cause said plate to close one end of the space between the saddle and the support and hold grout in said space, an outer fascia plate secured to the saddle and extending downwardly therefrom to conceal the first plate, and means for engaging and holding the lower end of the fascia plate.

'7. A means for positioning door saddles and the like comprising, a saddle adapted to be held horizontally and spaced from a support to permit the insertion of grout between it and the support, brackets resting on the support and adjustably engaging the opposite ends of the saddle, means for adjustably securing the brackets to the support, and a plate carried by the saddle for extending over and concealing the space between the saddle and the support.

8. In a construction of the class described, the combination of several spaced brackets, a base on which said brackets are secured, means for adjusting the positions of said brackets relative to the base, a saddle supported at its ends only between the brackets and at a distance above the base to provide a space between the saddle and the base in which grout is received, and means carried by the saddle for closing one end of said space and holding grout therein.

9. In a construction of the class described, a support, a saddle held spaced therefrom so that grout may be placed between the saddle and its support, means carried by the saddle for closing one end of the space and holding the grout therein, and means for permitting horizontal and vertical adjustment of the saddle relative to its support.
