Specification of Letters Patent.

Patented April 30, 1907.

Application filed February 18, 1905. Serial No. 246,324.

1-"0 (LZZ whom, it may concern.-

Be it known that I, DANIEL SOIIUYLER, a citizen of the United States, a resident of San Diego, in the county of San Diego and 5 State of California, temporarily residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a new and useful Semi-Metallic \Yall Structure for Sliding Doors, of which the following is a specification.

This invention is an improvement in a wall structure heretofore invented jointly by Homer Laughlin Jr, and myself and set forth in our application for Letters Patent of the United States, filed July 25, 1904, Serial No. 218,060 which so far as I am aware sets forth the pioneer steel structure for purposes of this kind and which application contains basic claims dominating the invention set forth in this application.

This invention is particularly designed for increasing the perfection of the system of sliding doors known as the perfect sliding door system.

An object of this invention is to improve the invention set forth in said joint application by increasing the strength and rigidity of portions thereof without increasing the cost and without greatly adding to the weight 3 of'the structure, and at the same time making improved. provision for fastening to the metal portion of the structure, the timbers of wood or other material which rec uire to be fastened thereto in completing the wall for practical use.

Another object of the invention is to so construct the wall structure having a pocket for a sliding door, as to avoid any liability of injury from shrinking, warping or twisting of 40 any wooden portions which may be applied in completing the structure.

This invention is designed to be embodied in a structure, the skeleton or main frame of which is principally or mainly of sheet steel 5 or other sheet metal reinforced and supple mented to a greater or less extent by parts made of wood or other suitable material.

An object of this invention is to provide a structure for the wall pockets and doorways of sliding doors whicl'i can he finished with narrower casings than has heretofore been possible with sliding doors; also to make provision for the most ready and convenient l manner of fastening the timbers and exterior finishing parts such as the casings, jambs and stops to the metallic f nine of the structure.

Another object is to provide a sliding door pocket structure of superior rigirilitysmoothly lined on the inside and adapted to wooden and metallic lath iml'iseriminately. In this connection the invention includes the combination with the wall-pocket frame, of fluted siding which is preferably matched or tongued and grooved and which may be fastened to the frame with the flutes or channels running diagonally, horizontally or vertically, the diagonal arrangement being deemed preferable forthe wooden lath and the horizontal arrangement for metallic lath.

An object of this invention is to bring into one solid, firm and practically unitary structure all of the elements essential for the in stallation and themaintenance in operative condition of any of the closures of the perfect sliding door system; provision being made whereby said structure, though originally constructed for the gravity closing sliding door, can by the removal of certain parts be adapted for the reaction closed door or any other form of door of said sliding door system; provision also being made for adjustment of the rail of said structure, both as to height, inclination and tension, also providing for most ready removal and replacement of said rail; and also to improve the structure over other forms in particulars which will hereinafter be more fully detailed.

The invention is applicable in the construction of wall pocket structures for both single and double doors.

Another object is to provide a semi-metal lie door-pocket wall-structure in which a greater or less number of the metal parts may be applied with other portions made of wood or other material instead of metal to form substantially the same mechanically effective structure, so that the metal portions of a structure having a wholly metallic frame and of a structure having a frame partly of metal and partly of some other material may be made with the same set of rolls and dies. That is to say, with this invention it is not necessary to construct the entire frame of steel; although that character of structure is deemed preferable, except where the user may prefer for economical or other reasons to make the structure partly of wood or other material. a

Another object of the invention is to provide a sliding door structure adapted for use inter-changeably for the gravity closed door having an inclined rail, and for the doors having a horizontal rail.

Another object is to provide improved means for mounting the rail at both ends of the structure and giving greater stability to the rail and supports in said system than has heretofore been possible.

A further object is to provide means by which the rail can be easily taken out of the structure and replaced at any time which has heretofore been impossible without destroying portions of the wall and other parts of the'structure.

Another object is to provide means for adjusting the cantaliver pressure to the rail after the closure is mounted, without removing any part or parts whatever of the structure, closure, or fixtures. Heretofore this has been impossible.

Another object is to provide for greater up and down adjustments of the'rail than has heretofore been possible.

Another object is to make accessible the centerbrackets and hangers where double doors are used, to such an extent thatthey can be quickly and easily taken out or replaced.

A further object of the invention is to so construct the structure as to insure the appropriate mounting of the same and to avoid the liability of misassembling or misarrangement of the parts, frequently occurring through ignorance or malice of carpenters in installing the former wooden structures.

Another object is to provide for the right construction and economical application of various, parts to the structure by means of which the rail supports or brackets of said structure may be adjustably mounted therein in the simplest, most efficient and satisfactory manner, and so as to insure the highest accuracy of exact positioning and the utmost certainty of maintaining true position.

Another object is to provide maximum adjusting space for adjusting the closure toward and from the rail with minimum depth of header, an object being to allow the clo sure to be raised to leave space for a rug when it is desired to place a rug over the threshold; or to bring the closure down close to the bare floor when so desired.

An object of this invention is to make provision whereby the trade may be furnished with a semi-metallic wall structure for sliding doors, of different grades, in some of which the frame of the structure will be entirely metallic and in others of which wood or some other material will be substituted for parts of the frame whichwill ordinarily be of metal. I purpose in some instances to substitute a wood back-post and a wood front door-post for the back-post and front doorpost which by preference will usually be partly or wholly composed of metal.

Another object of the invention is to so construct the sliding door structure as to enable any workman to readily insert and remove the rail at any time before or after the house is completed and also bring the rail to the rigid, firm and stable condition required of the rails in the perfect sliding door system.

Another object is to make provision for giving a greater or less thickness of wall with a single thickness and style of steel frame.

Another object is to provide an improved mounting for the buffer spring of the reaction closed door of said perfect sliding door sys tem.

Another object is to provide an improved mounting for the cantaliver rail brackets and at the same time provide for tying together, stiffening and strengthening the frame.

Another object is to provide for mounting the rail brackets adjustably at the slightest expense.

Another object is to avoid a difhculty which has heretofore existed in said perfect sliding door system towit:It has been found that with the character of screens heretofore employed tov form the side walls of the slots in which the bolts for supporting the closures move, the workmen were liable in installing the structure to so construct and mount said slot screens that they would interfere with the door hanger, thus preventing thesmooth anti-friction movement of the closure which is characteristic of the doors of this system when properly installed. For the purpose of avoiding such difficulty and of attaining various other advantages, I provide a novel slot-screen in the form of a thin metallic blade which is preferably provided with a flange, the blade and said flange being formed as an angle iron and the flange being provided with perforations through which nails or screws may be inserted for the purpose of fastening the screens to the head amb.

With ihe previous forms of door structure with which 1 am acquainted there is liability of injury to the same by careless and wrong handling of the closure in installing or ad justingthe same. An object of this inven tion is to pzovide against accidents of this nature and to make it more convenient for repairing any damage which may be done in this way. This I accomplish by constructing a metallic screen in the form of a thin blade as above stated and fastening the same to the inside of the head j amb. Said metallic screens are to be manufactured and carried in stock and while thin yet of such thickness IIC hanger is shown. Fig. 20 is a view showing joined fluted boards for the siding. Fig. 21 is a view of the blank for forming the body of the back bracket support.

In the present invention certain members of the structure may be designated in a general way as follows :A, front door post; B, back or rear post; C, header; D, mouth posts; G, iron stays.

1, 2, 3 are external sheet metal frame members made of channel iron, preferably sheet steel, to form a portion of the front and back posts and header, respectively, of the'structure. 4, 5 respectively designate in a general way means at the junctions of said header and said posts for supporting rail brackets which are designated in a general way by the characters 6, 7; said supporting means being fastened to the header 3 and to their

posts

1, 2 respectively and tying said header and posts together; and each of said bracket-

supports

4, 5 being provided at the lower end with a projection for supporting its bracket. Said projections are designated respectively by the

characters

8 and 9. 10 is a loop at the upper portion of the back bracket support, and 11 a bridge on the supporting projection 9 of said bracket support. The back cantaliver bracket 7 for supporting the rail 12 has a base 13 which extends above and below its bracket arm 14; the upper extension 15, of said base being provided with a perforation in the form of a slot 16 and the lower extension 17 being interlocked with said bridge 11 by means of a boss 18 and seat 19 on the bridge and lower extension. 20 is a fastener in the form of a rivet extending through the loop 10, the upper extension 15 of the base, the back bracket support 5, and the channel iron 2 of the back post. The cantaliver bracket 6 for the frontpost, is pro vided with a

base having extensions

21, 22 above and below its bracket arm 24 the lower extension 22 having a vertical screw hole 23. An adjustii'ig screw 25, having collars 26 engages in a slot 27 with the lower projection of the front bracket support, and

screws into the screw-hole 23 in the lower ex tension 22 of the front bracket 6 to raise and lower said bracket.

28 is a loop fastened to the front bracket support 4 and through this the upper exten sion 21 of the front bracket 6 moves so that as the screw is turned, the frontbracketwill be raised or lowered.

29 is a rail socket in the back bracket; the same being lower than the top of the outer end of the back bracket when the base of said bracket is upright, so that when the rail 12 is resting on the inner or back cantaliver arm 14 and has its back end inserted into the rail socket 29 and its front end brought over and down toward the cantaliver arm 24 of the front bracket, it will be engaged at top and bottom by, and thereby cramped firmly in the bracket, but can be readily withdrawn and reinserted by simply lifting the front or outer end and then moving the rail endwise.

30 is a stirrup extending over the end of the rail which is above the front bracket arm and 31 is a set-screw, screwed through said stirrup and into a seat 32 in the bracket arm 24, so as to draw the front end of the rail downward by pressure on the top thereof. Said

bracket arms

14 and 24 are slanted upward toward each other with an open space between the front brackets and the end of the rail so that when the screw 31 is tightened, it will tend to bow the rail by straining it over the tips of the cantaliver arms, and will thus bring the rail and the several parts of the structure hereinbefore enumerated into tension.

By the means above described it is made possible to insert, remove and reinsert and adjust the rail at pleasure.

It is to be noted that the screw 31 engages the under face of the bracket and is below the bracket and readily accessible and that by this construction the trough-shaped rail 12 is fastened in place, although it chambers the bracket.

33 is a U shim of spring wire springing in between the side walls of the back bracket support above the rivet 20 between the upper extension of the back bracket and its support to bring the outer end of the cantaliver arm 14 downward slightly below where it would otherwise stand when the bridge 11 is used as shown in the drawings; thus to avoid the necessity of producing too great tension in the rail when said rail is arranged in its slanting position for the gravity closing sliding door. arms of the brackets are inclined upward at an acute angle with the upper extension of the base of the bracket, and the rail socket 29 is arranged in such position relative to the bracket arm 14 that when a straight rail is simply rested on the arm and its end is simply inserted into the socket 29 said rail will extend almost on a level; but Will have a slight upward slant outwardly, so that when its other end-is brought down to a level, there will be a slight tendency to arch produced in the rail thus to give superior supporting quality to the rail.

The stirrup 30 and its set screw 31 on the end of the rail engaging the under-side of the front bracket arm enables the workman to accurately adjust the tension of the rail so that if the weight of the closure should be sutlicient to cause a sagging deflection of the rail at its middle, such sagging may be remedied by screwing the screw 31 tighter, and vice versa.

' The rail may be adjusted as to level or inclination by adjusting the collar set screw 25.

It is obvious that when the tips of the bracket arms are in the same horizontal That is to say, the cantaliver plane, less tension will be given the rail upon bringing its front end down into position on the front bracket while the rear end is cramped by the rear bracket than would be by given by bringing said front end to the same position when the rear bracket is upheld by the bridge 11 as shown in the drawings. Consequently, when it is desired to use the same fixtures for mounting the door and yet mount it as an ordinary horizontal sliding door or as a re-action closed door in which the rail is mounted practically horizontally, it becomes desirable to lower the bracket 7, then the bridge 11 and the shim 33 must be removed, or which is just the same, should be omitted from the structure.

34 is a timber fastened by screws or nails 35 in the channel of the front post channeliron, 1. K is a block fastened to the upper portion of said timber by screws 36. To this block, the front bracket support 4 is fastened by screws 96. 37 is the jamb against which the closer, I, shuts. Said jamb appears in Figs. 8, 9 and 16. It is fastened on the timber 34 and fitted below the bracket block K.

38 is a cleat fastened by rivets 39 to the channel-iron 3 of the header and serving to gether with block K, wl 'ch it engages, the jamb timber 34, fastened in channel iron 1, screws 36 and 96, loop 28, rivets 4.0 and the rail bracket 6, and its adjuncts such as stirrup 30, to complete the means which unite the rail and the members of the external frame in a rigid unitary structure.

41. 1s a plate which forms the main body of the front rail bracket support. Its upper end engages the cleat 3S and fits between the sides of the loop 28 which slidably holds the upper extension 21 of the front rail bracket 6.

42 designates metal ties connecting the end posts 1, 2, together below the channel-iron member 3 of the header. 43 designates sheet metal mouth posts on opposite sides of the structure, respectively fastened to said ties 42 and to the head 3.

44c, 45 and i6 designate ties connecting the mouth posts respectively to the back post.

47 designates re-inforcing sheet metal strips fastened to the mouth posts and provided with projections 18 extending transversely of the posts; said mouth posts and strips being perforated and timbers 19 provided for completing the mouth posts; the same being held by said projections and by nails or screws 50, 51 driven through the sto p 81, through said mouth posts and re-inforcing strips into said timbers. The transverse projections 18 form solid braces for strengthening the post. The strips 47 are desirably formed of flat strap iron bent over at the ends,- thus to form the braces in a simple and effective way without interfering with the placing of the timbers.

The lower channel-iron tie 46 has its channel upper-most and the upper channel-iron tie 4.4 has its channel dmvnward. 52 designates longitudinally grooved siding fastened Y in place in said channels and against said timbers 49 which may or may not be extended by furring 53.

54 designates brackets on the door-way side of the mouth posts, and 55, brackets on the outer faces of the front post. F designates the head timber mounted in said brackets on opposite sides of the frame.

56 designates the head jambs fastened to the timbers 1*. 57 designates sheet metal slot screens for said head jambs respectively, each comprising a metal plate fastened to and extending inward from its head-jamb 56 to form together a narrow slot extending along the mid-line of the rail.

58, 59, 60 and 61 designates anchor-plates extending across the bottom of the structure frame and connecting the mouth post and lower channel tie of one side of the structure with those on the other side of the structure.

It is very important that the closuresupporting rail of a sliding door structure shall be mounted with perfect central trueness in order that the closure can move in a cavity of minimum dimensions without liability of rubbing. The rail 12 shown is a sheet metal rail of an approximately trough shape; the same being described and claimed in an application filed by Homer Laughlin Jr., and myself, June 18, 1904, Serial No. 213,121.. in order to secure this absolute centering of the rail it is necessary to provide means by which the workman will be compelled to properly locate the rail bracket supports and this is done by means of the

loops

10 and 28, one of which accurately fits into the back bracket support and over and against the sides of the upper extension of the back bracket and between the same and the side walls of the back bracket support, and the other of which is used to clasp and centrally locate the front bracket extension. The rivet 20 for the back bracket is riveted through the bracket support and the back steel post or frame. The loop 28 is used to center and firmly clamp the upper extension of the front post bracket and is riveted by rivets 4 0 to blockK, which in turn is screwed fast to the wood lining or timber of the front post by the screws 3 6 through block K and also by screws 96 through plate 41, block K and into timber 34.

In constructing a reaction closed door, the buffer spring 62 is preferably mounted on a foot 63 formed of a sheet metal loop riveted to the channel-iron 2.

In case it is desired to use wooden front and back posts, such posts may be substituted for those shown.

64 designates a timber fitted against the channel-iron 2, flush with the sidesv thereof for nailing the back edge of the siding thereto.

designates upright stays connecting the

members

2 and 42 of the header substantially inthe manner shown in said application Serial No. 218,060. The sheet metal parts are preferably secured together by rivets 66.

The back bracket support 5 is preferably formed of a single blank steel sheet of rectangular form slit and bent to form the side walls 68, bracket supporting projection 9, laps 69 for sustaining the same and a head 70 for fastening the support to the header.

In Fig. 21 the solid lines 71 indicate the slits in the metal and the dotted lines 72 indicate the lines along which the bends are made for forming the completed support.

73 designates the base to which the wall structure above described will be fastened. The same may be a board or timber tempo rarily secured to the metal frame for holding the bottom of the door post during shipment, or it may be the floor of the building in which the structure is installed.

74 designates nails or screws through the anchor plates, fastening the frame to the base.

By the construction herein described, the wall pocket structure of which the rail, its brackets and the adjuncts thereto are thus made component parts is given great rigidity and strength with a minimum thickness of wall and at the same time the rail is made accessible and peculiarly adapted to adjustment and to removal and replacement.

hen it is desired to remove the rail from the structure, the set-screw 32 will be loosened and the stirrup 31 will be slid to the right beyond the bracket arm 24. Then the adjusting screw 25 may be screwed up, thus raising the bracket 21 until the screws 96 are exposed whereupon by unscrewing the same, the front bracket support 4 with the bracket 21 may be taken down, and thereupon the rail 12 may be withdrawn from its socket 29 and readily withdrawn from the wall pocket. It may be replaced by reversing the operation just describing; it being an easy matter to place the back end of the rail over the bracket arm 14 and insert said rail end into the seat 29 to then replace the bracket support 4 with the bracket 6 therein and secure it by the screws 96 and then bring the stirrup 31 into place and clamp it as before.

The boards for the fluted siding may be of any suitable width. Preferably they are grooved or fluted to form three ridges; the edge ridge 75 being the same width, and the intermediate ridge 76 being twice that width and less in width than the grooves 77, respectively, so that when the boards are matched together the siding will present ridges and grooves of uniform width, respectively.

By the construction shown, the mouth posts of the wall-pocket may be sufliciently rigid without requiring so great cross-sectional dimensions as is required in the mouthposts of the wall-pockets for sliding doors heretofore constructed. I have constructed in accordance with this invention, mouthposts for wall pockets of a sliding door having an opening seven feet high, in which the crosssectional dimensions of each of the mouth-posts were two and one-quarter inches by one and one-half inches; and the same are more rigid. than the former mouth-posts, the cross-sectional dimensions of which were more than twice that stated. By this construction, therefore, I am enabled to use casings as narrow as three and one-quarter inches; and by means of the furring strips 58, the width may be increased indefinitely and the stiffness is, of course increased by the addition of such furring strips. When the tongued and grooved siding is fixed in the channel-irons and nailed to the posts or the furring thereonas the case may be, the rigidity of the wall is immediately increased; and with the addition of the lathing and cement or plaster applied thereto to finish the wall, the structure is more solid than it has heretofore been possible to construct a sliding door wall-pocket structure, of like dimensions.

By making the'wooden portions in sections an advantage is gained in that there is practically no liability of any such warping as can displace or interfere with the trueness of the metal frame. The projections or portions 48 bent at right angles to the main bodies of the strips or straps 47 help greatly in adding stiffness to the posts. Some of said projections 48 are respectively furnished with a further bent portion 75 so-as to embrace the lower end of the timber 49 which seats thereon. It is to be understood,- however, that the invention is not strictly limited to a structure in which the reinforcing straps 47 and the timbers 49 are in sections as shown.

' It is to be observed that the mouth posts are the portions of a wall pocket structure that are most subject to strain; and thatby constructing the same of angle iron with a reinforcement of strap iron 47 laid against the outer edge flange 76 of the angle iron upright, the angle iron may be made of the same thickness as the other parts of the sheet metal frame. The strap iron 47 and all the other sheet metal portions of the frame are preferably of the same thickness and their widths are preferably the same as, or are aliquot parts or multiples of each other sp that a sheet of metal of determined width made at the rolling mill may be slit to the appropriate sizes for the several parts respectively, and then run through the necessary rolls respec I tively, to form the appropriate parts of the structure.

The slot screens 57 are desirably made of angle irons each having one of its flanges 77 perforated for screws or nails 78 by which it is fastened to the inner face of the head j amb 56 that is detachably mounted on the head i and the front and back posts of timber F by screws 79. When the head jamb is detached, the screen therefor may be fastened thereon either longitudinally or aslant and when the head jambs are in place i the means by which the screens are fastened thereto, are completely concealed. The slotscreens 57 are oppositely arranged with a narrow slot between them, thus providing a slot immediately below the center of the rail, as clearly shown in Fig. 19, and each is provided with an upwardly extending perforated flange 77 by which it is fastened to the head jamb of the wall structure so that the means of fastening are concealed from view. The head stops 83 project underneath the joint between the head jambs 56 and the slotscreens so that said joint is concealed.

The bracket arms are wedge shape, widening from top edge downward and the edges of the trough shape sheet metal rail engage therewith and are sprung apart thereby when the pressure of the stirrup is applied on the top of the rail. Thus all looseness is avoided.

By omitting the post A with channel-iron 1 the remainder of the structure is adapted for one-half of a double sliding door structure which may be formed by uniting a like half thereto by any suitable splicing not shown.

The intermediate ties l5 are desirably llat where the siding is used and the siding 'lits against it so as to be supported thereby; but it is to be understood that for metal lathing the angleiron ties shown in said application No. 218,060 will be preferred.

S0 is the back jamb, 81 the back stop and 82 the front stop.

The rail held in tension in the metal frame forms a stay tending to hold the entire frame solid.
