Specification of Letters Patent.

Patented Dec. 12, 19115.

Application filed June 12, 1916. Serial No. 103,665.

To all whom t may concern Be it known that I, SAMUEL J. Win'rnns, a citizen of the United States, and residing at Plymouth, in the county of l/Vayne and State of Michigan, have invented a new and Improved Door-Sill, of which the following is a specification.

This invention relates to a metal door sill, and among its important features is the provision of a hollow sill of such nature as to rest flat upon the upper surface of the rough flooring and to overlap the top flooring whereby extra carpenter worlr is avoided; the invention also consists in provision of nailing blocks in the outer ends of the hollow sill whereby the door jamb may be readily secured in place without special cutting and tting.

rlhe invention further consists in the details of construction shown, described and claimed.

ln the drawings, Figure 1 is a transverse section through the sill showing its relation to adjacent elements. Fig. 2 is a plan view of the sill, parts being broken away. Fig. 3 is a fragmentary perspective view of the sill taken from a position which corresponds to a point in the interior of the building or room into which the door opens.

1 and 2 indicate, respectively, the rough flooring and the top or finish flooring-as will be observed, the former preferably extends substantially to the front face 3 of the wall wherein the sill is to be used, whereas the top flooring terminates at about the inner face of the door t which swings inwardly (to the right, Fig. 1) in the customary manner.

Resting on the upper surface of the rough flooring is a hollow sill, preferably of metal, comprising a base plate 8 and a tread plate 9 that are joined by an inner longitudinal wall 10 which may abut against the face of the top flooring. These plates are also joined by an outer wall 12 which may be extended below the plate 8 at 13; the plates 8, 9 and the wall 12-13 may be extended laterally at each end of the door opening for a distance substantially equal to the corresponding dimension of the front board 14 (Fig. 1) of the casing and may merge into the end wall 15, thus forming a box-like projection, the inner face of which is in line with the outer surface of the wall. A short distance from each end the

plates

8, 9, 10

and 12 are connected by the cross walls 16-thus open chambers are formed wherein wooden nailing blocks 18 of appropriate size and shape may be inserted, these blocks being preferably retained by nails or screws 19 that pass upwardly through holes in the plate 8, whereby loss in shipment may be avoided. The plate 9 is preferably inclined upwardly and inwardly to a point somewhat to the rear of the front edge of the door when the latter is closed, which gives water an opportunity to freely drip from the door and prevents it from driving in beneath the latter; and the upper surface of this plate may be roughened or corrugated as shown at 20 (Fig. 2) for obvious reasons. At its inner edge the plate projects over the upper surface of the top flooring in the form-of a tapered lip 21.

For the purpose of further strengthening the tread 9, it may be connected to the wall 8 at intervals by abutments 22; and it is obvious that the lateral extension of the

plates

8, 9 and 13 beyond the edges of the door opening may be omitted-this co1i struction being, for example, particularly adapted for freight cars. Other changes in the details of the device may, of course, be made, and I do not therefore wish to be limited except as indicated by the subjoined claims.

1. A door sill comprising a base plate and a tread plate spaced from each other and connected together, and nailing blocks interposed between the plates at their ends whereby the casing of the door in which the sill islfo be used may be readily attached to the s1 2. A metal door sill comprising a base plate and a tread plate spaced from each other and connected together, nailing blocks interposed between the plates at their ends whereby the casing of the door in which the sill is to be used may be readily attached to the sill, and means for retaining the nailing blocks in position in respect to the plates whereby they are prevented from dropping out in transportation.

3. A door sill comprising a base plate and a tread plate spaced from each other and connected together, nailing blocks interposed between the plates at their ends whereby the casing of the door in which the sill is to be used may be readily attached to the sill, and

a tread plate spaced from each other and,

connected together, nailing blocks interposed between the platesy at their ends whereby the casing ofthe door in which the sill is to be used maybe readily attached' tothesill', andl a cross wall joining the plates near each end whereby the nailing blocks. arev Vprevented from being driven inwardly.

5. A hollow door sill` comprising, a base plate and. a tread plate spaced therefrom, a`

nailing piece interposed between the plates, an outer longitudinal wall joiningjthebase plate and tread plate, said outer wallv and said tread plate being extendedjbeyond the nailing block and being joined by a transversely extending end wall Vwherebyl the outer portion of theV nailing block is concealed when the sill is in use.

Y6. Asfan article of manufacture, a. door.. sill comprising a metal. tread plate and wooden nailing pieces `located beneath thc ends of said tread plate and means whereby said nailing pieces are prevented from movement relative to said tread plate whereby the casing of the door in which the sill is to be used may be readily nailed to the sill.

7,. As. an article of manufacture,v a metal door sill including a tread plate, said sill being shaped to, form sockets at its ends for the reception of wooden nailing pieces to which the casing of the door in which the sillis to be used may be readily nailed.

8. As, an (nticle of manufacture, a door silly comprising a metal tread plate,y and a wooden nailing piece located; beneath, the tread plate and terminating substantially at one end face thereof, and means whereby said nailing piece is prevented from movement relative to said tread plate, whereby the casing ofy the door in which the sill is to be used may be readily nailed to the sill.

In testimony whereofl I sign this specilication.
