BUILDING CONSTRUGTION.

SPECIFICATION forming part of Letters Patent No. 52,219, dated .iune 19,1900.

Application filed August 19. 1899. Serial No. 727,760- (No model.)

To all whom, it may concern.-

Be it known that I, J OHN CoTTER PELToN, a citizen of the United States, residing at New York, in the county and State of New York,

have invented certain new and useful Improvements in Building Construction, of Which the following is a full, clear, and exact description.

My invention relates to improvements in to building construction, and particularly to the construction of a floor that shall possess unusual firmness and strength, while at the same time being unusually light in consequence of the economical employment and I 5 distribution of the several parts thereof. In

addition to the abovefeatures the floor possesses the advantage of being fireproof.

My object, therefore, is to provide a flooring for buildings that may be simply and rapeo idly constructed and that shall combine the above advantages.

In the drawings, Figure 1 is a sectional View of a portion of flooring, said section being taken on a line parallel with the iron beams commonly employed. Fig. 2 is a side elevation of one of the details of construction, partly in section. Fig. 3 is a side elevation of another detail. Fig. 4 is a side elevation .of a detached strengthening-core of .what I shall hereinafter term a lintel-block. Fig.

5 is a sectional modification. Fig. 6 is a section of a portion of a lintel and strengthening-core.

A is a floor block or tile. B is an internal 3 5 metallic strengthening-core in the form of a perforated sheet of metal, the opposite edges of which may, if desired, be upset or swelled or wrapped around a rod B, by which said edges may be anchored. In constructing this floor-block any suitable material which can be molded-for example, concrete-may be employed to envelop the perforated strengthening-strip B, which material when once set is anchored through and through said strip, thus making the addition to the swelled edges merely an additional means of security. It is because the core 13 is captured by the material of the floor-block A at so many points that.in many instances said core may comprise merely a comparativelythin sheet of metal. While it is preferable to have the perforated sheet-metal cor'eB flat, or substantially so, the same may, if desired, be concaved. These blocks A in my pre- -ferred construction have their ends downwardly and inwardly inclined and have a fiat, even, and comparatively-smooth bearing-surface to take up uniformly against the supporting member, termed the lintel-block, which will now be referred to. The lintel-block F is shown in detail in Fig. 2, in which its position is illustrated with reference to the iron supporting-beams such as I prefer to employ.

D D are iron beams, cominonly termed I- beams, which derive their support in the usual manner. Between these beams D D the lintel is placed, and as many of them may be employed as may be determined is necessary. The lintel-block comprises a central strengthening-core E of suitable material, preferably metal, in which core are arranged rows of obliquely-faced perforations, by which I mean rows of perforations which are inclined in opposite directions away from the center of the arch, the pitch of which gradually decrease toward opposite ends of the core E, which may be readily understood by referring to Fig. t. Around this core is formed an envelop of concrete or other suitable material, which preferably entirely covers the core and passes through the perforations therein, so as to form a secure anchorage for said'core at each perforation, as shown in Fig. 6, which view merely illustrates a portion of a lintel F, said section being taken upon a line to indicatea perforation in said core through which the enveloping material passes. The finished lintel-block is of a shape which in general may be best seen by reference to Fig. 1, in which it will be observed that the lower portion thereof is the thickest and preferably of an angular outline. The sides of the lintelblock converge toward its upper edge at an angle corresponding as nearly as possible to the ends of the floor-blocks A which are to be supported thereby. If desired, abrupt shoulders F may be formed on the outer surface of the lintelF at a point adjacent to the lower abutting surface of the floor-blocks, which arrangement will be found very de- I00 sirable in fireproof construction. It is preferable that the web or core E, by which the No. 652,220. Patented June 19', woo.

To aZZ whom it may concern: the button-trough, and the end of the yield- Be it known that I, EUGENE M. PHELPS, a ing material-supporting tongue, which is secitizen of the United States of America, recured beneath the table.

Fig. 5 is convex-headed bolt T thereon, whose head a plan view of the lower end of the pivoted engages said pulley centrally when said lever section of the button-trough. Figs. 6, 7, and is swung to force and hold the driving-pulley 8 illustrate different parts of the button sewagainst said hand-wheel E while the machine 0 4o ing and feeding devices in Various operative is running, and swinging away from the drivpositions relative to the button-trough and ing-wheel causes themachine tostop,as aforeon line a: acthereof, Fig. 5, and are fully desaid. Said clutching-lever is held normally scribed below, Fig. 8 also illustrating the manso that the said driving-pulley D is out of enner of making the two-loop stitch of this magagement with the hand-wheel E by a spring 95 chine. Fig. 9 isa vertical sectional view of W, supported on a post, as shown in Fig. 4. the button-hopper about on line 9 9, Fig. 1, A startinglever Z is hung on said table, (see showing a portion of the button-trough in Figs. 1 and 4,) one end of which extends unfront view and a section of the trough with a der said lever S, and a rod Y, connected to buttontherein onliney'y. Fig. 10 illustrates the outer end of said lever Z, forms a conloo 5 in perspective views the combined presserneetion with a suitable foot-treadle, (not footand button-holder,thelower extremity of shown,) so that by operating the latter the I clutching-lever S and driving-pulley D are actuated to start the machine, as aforesaid. A lever B, Figs. 1 to 4, inclusive, pivoted under said table, has its upper end extending opposite one edge of the clutching-lever S and has a shoulder X for engaging the latter to hold it in the position which secures the operative contact of said pulleys D and E. Said lever R slips out of connection with the clutching-lever S when free to swing. Therefore a lever 14, Fig. 2, is pivoted on said table, having an adjustable bearing-plate 15 on its longer arm engaging a pitman 4, which has a certain degree of vibratory movement, whereby said lever 14 is so caused to swing that its short arm is moved against the upper end of said lever B and so holds the latter temporarily in engagement with said clutching-lever S, and then in the opposite direction, leaving the said end of the lever R free to swing away from the lever S. The lower end of said lever. R extends opposite the side of a gear-wheel 0, Figs. 1, 3, and 4, which is rotated by a pinion N on said main shaft 0.

A roller-stud P is carried on said gear-wheel O, which once in a revolution of the latter trips said lever R and swings its said upper end out of engagement with the clutchinglever S, letting the latter swing to carry its .said headed bolt T away from the drivingpulley D and stop the machine. The movement of the said roller-stud P relative to the lower end of the lever R is so timed that during its movement after passing said lever (the machine being then started again) the number of needle movements for sewing six (more or less) stitches through the fabric and the button-eye will be accomplished. The said pitman 4 is connected by its upper end to the end of an arm 5, secured on a rockshaft 6, hung on the side of the machine-arm B. Said pitman carries on its lower end (see Fig. 11) a cam-yoke 3, in which are cam-engaging parts or surfaces normally at varying distances from the axis of the main shaft C, on which is the cam 2, which actuates said pitman forlongitudinally-reciprocat ing movements and correspondingly varies the extent of the rocking movements of said rock-shaft 6. The degree of the vertical movements of the presser-foot bar 9, on which is carried the cupped presser-foot 12, is also varied by the action of said cam 2. Said pitmau cam-yoke 3 is held in the position shown in Fig. 11 relative to the cam 2 by the engagement of said bearing-plate 15, (on lever 14,) and when the lever 14 is freed, as aforesaid, a spring 13 draws said cam-yokelaterally or in the direction of the arrow 49, Fig. 11, so that the more separated surfaces thereof are brought opposite the cam, and thus vary the movements of said pitman, as aforesaid. An arm 8 on said rock-shaft 6 is connected to said presser-foot bar 9, as shown in Fig. 1. Said presser-foot 12 has its lower end cupped or provided with a concavity of such depth and form as best adapts the same to receive, substantially, the entire upper convex section or face of the button, so that it may, as shown in various figures of the drawings, suitably engage and hold the button in a position vertical to the face of the fabric to which it is to be attached while the button is being sewed on.

A cross'shaft H is hung under the table, which is rotated by a bevel-gear connection with the main shaft 0, as shown. Said crossshaft has a grooved cam 46 thereon, which actuates the take-up 45, and to a crank on said cross-shaft is connected a pitman, and the latter is connected to asliding yoke I, to which the needle-bar J and the sh uttle-actuating lever M (engaging a crank on the shuttle-pivot) are connected, as shown, and whereby the needle 38 is given its requisite movements and said shuttle is reciprocally rotated, as usual.

The needle, oscillating shuttle 42, take-up 45, and tension 44, all of which are illustrated in Fig. 2 in their relative operative relations, constitute sewing devices of wellknown character for making a stitch embodying a needle-th read and a shuttle-thread inter-looped, as shown in Fig. 8, and are herein illustrated as one of the numerous stitchforming mechanisms which is preferred for the purposes of this invention and whose operation is well known to those skilled in the use of sewingmachines.

Under the table A of the machine a springtongue 33 is rigidly secured by one end, Figs. 1 and 3, which constitutes a yielding support on which are carried, beneath the usual throat-plate 50, the slotted work receiver or support 34 and the work-holding block Fig. 1 clearly illustrates the normal posit-ions of the last-named parts. The track of the needle while sewing is centrally through the button-space 36 between said parts 34 and 35, (see Figs. 1 and 10,) and the cupped presserfoot 12 has vertical movements centrally over said button-space.

Figs. 6, 7, and 8 each illustrate the different positions which the button, the fabric, and the lower free extremity 28 of the button-raceway assume, respectively, in sewing on the buttons. Therefore to meet the requirements of said varying or different positions, to provide an efficient and constant supply of buttons at a point over said needle 38, to provide a raceway having a vibratory movement between said fabric and presserfoot and in which the button is held while being sewed onto the fabric, and to provide for holding said raceway always in position over said work-receiver and for the convenient exit of the sewed-on button from said raceway through a side opening the button separating and feeding mechanism (illustrated in Figs. 1, 5, 6, 9, and 10) is provided and is constructed and operates as follows: The said button feeding and separating devices comprise a button-hopper 17, having button-conducting grooves 23 in the inner wall thereof, extending in opposite sides of the bowl from vent the stoppage of buttons therein.

by screws 26, one border of said cover be ing left open for free communication with buttons that may be in said groove to pre- Said covered portion of the raceway extends to a supporting-post 27, secured on said table. Buttons placed in said hopper 17 are acted upon for moving them to become engaged in said button-conducting grooves 23 by a series of brushes 18, as shown, secured in a carrier 20, the latter being hung on a shaft 19, extending through the wall of the button-hopper, and having a crank 21 on its outer end. An arm 7, secured on said rockshaft 6, is connected by a link 22 with said crank 21, and thereby the brush-body and brushes are given a swinging motion, whereby the buttons are acted upon, as stated. In Fig. 2 the upper end of said post 27, which supports the .lower end of said upper raceway-section 24, is shown in section and illustrates two fixed outside sections of said post and two next adjoining sections of the lower .end of said raceway-section 2 1, and pins 52 lock said last-named parts to said post. The lower or vibratory section 28 of the raceway is hinged by its upper end to said post 27,

said pins 52 also attaching it thereto, and.

they constitute the pintles of the uniting-joint of said sections 28 and post. A button-eye groove in said racewaysection 28 com muni cates with the like groove of said upper raceway-section 24: and extends nearly to the lower free end thereof, where the formation is as illustrated in Fig. 5that is, having no exit at its extremity in line with the button-eye groove, but having such exit at one side of said groove, whereby each button after having been sewed to the fabric is drawn laterally out of the raceway. Furthermore, on the under side of the part of the latter which lies operatively over said slotted work-receiver 34: is a projecting lip 81, Fig. 10, for engagement in the slot of said part 34, whereby when a button is drawn out of the raceway the latter is supported against lateral strain. Said lower raceway-section 28 is normally held with its lower end swung upwardly by a spring 29 thereunder, as shown in Fig. 1, whereby the eyes of the buttons therein are primarily held above the fabric 41, to which they are to be sewed. The degree of upwardly-swinging movement of said section 28 is adjustable by means of a restraining-hook 30, having an arm engaging the latter, and means are thus provided for permitting a vertically-swinging movement of said racewaysection in consonance with the movements of the presser-foot, thus causing the head of the button to be kept in engagement with the said concavity in the lower end of said presserfoot 12 to such extent as may be desired while the button is being sewed on. The lower screw-threaded end of said hook 30 passes through a vertical slot in said supporting-post 27, and a nut thereon (see Figs. 1 and 4) serves to hold the same when adjusted Vertically.

In Figs. 6 to 8, inclusive, the presser-foot 12, a button, a section of the raceway-section 28, the extremity of the loop-engaging hook 13 of the shuttle, the slotted work-receiver 34, and a part of the needle are shown, all somewhat enlarged, in order that the relative posi tions thereof in respect to the fabric 41 (there shown) in the different stages of the operation of sewing on abutton may be clearly understood. The said button-sewing operation is as follows, and the positions of the presserfoot 12, the raceway-section 28, the lower button therein, and the fabric tl, held by the operator,are such as the said parts are brought to during said operation. In Figs. 1 to 4, inclusive, the parts are shown in the relative positions of rest which they occupy prior to sewing on a button.

Operation: The treadle actuating the starting-lever Z is pressed, thereby lifting the end of the clutching-lever S, freeing the brake projection 51 thereon from the hand-wheel E, and at the same time carrying the drivingpulley D against said hand-wheel E. The lever S is now engaged by the lever B, as stated, and the lower arm of the lever R is subject to be acted upon by said roller-stud P on the gear-wheel O, as described. The positions now assumedby the last-named parts result in the movement of the lower end of the pitman 4 by the spring 13in the direction indicated by the arrow 19, Fig. 11, thereby bringing the free extremities of the cam-yoke 3 nearer the axis of the main driving-shaft C, thereby giving to the presserfoot 12 the extremes of movement illustrated in Figs. 7 and 8 and in which positions the sewing on of the button is efiected, after which the presser-foot is lifted sufficiently through the action of the cam 2 upon said open extremities of the cam-yoke 3 (substantially as shown in Fig. 1) to let another button come to position between the presser-foot and the fabric and over the track of the needle 38 to be operated upon for sewing on. In sewing the form of thecam 2, in which is provided a longer curved face, (shown on its lower side in Fig. 11,) provides for certain socalled dwells of the presser-foot at its extreme upper and lower positions, as in Figs. 7 and 8, during each of which dwells the needle completes a forward-and-backward movement at one time through both fabric and button-eye, (see Fig. 7,) and, next, for ward and back under said fabric. (See Fig.

8.) The buttons follow down the two raceway-sections, the lower button stopping at a point over the needle, as shown in Fig. 1. The rapid vibratory movements of the lower sec? tion of the raceway, caused by the action of the presser-foot, serve to so agitate the buttons that they slide freely down. Fig. 6 illustrates the position of the button supported said) passes through the fabric and buttoneye, the loop of the thread on the needle being looped by the sh uttle-thread in the usual way, and, as in Fig. 8, the needle is then drawn back. The presser-foot now rises, and the fabric and button, carried by the springactuated work receiver 34, move upward therewith high enough, Fig. 8, to allow the needle to pass once back and forth under the part of the fabric directly under the buttoneye, the shuttle-thread being disposed as before, and then the parts again come to the positions of Fig. 7. Thus several interlocking stitches are taken alternately through the button-eye and fabric and outside the latter by moving the button-eye and fabric into and to one side of the path of movement of the needle, and when the number of stitches for which the machine is set is completed the machine automatically stops, as described. The fabric and the sewed-on button are then moved backwardly, drawing the button away from the raceway through the slot or opening 32 in one side thereof, Fig. 5. The operator then moves the fabric again under the raceway to space the next button, and the sewing operation is repeated.

What I claim as my invention is- 1. The combination in a machine for sew ing shank-buttons to fabric, of sewing mechanism, button-feeding mechanism comprising a hopper, and a raceway conducting buttons from said hopper to the fabric, means in said raceway for retaining a button therein while being sewed on, means acting in conjunction with said raceway for retaining a button therein while being sewed on, consisting of a presser-foot engaging the upper convex section of each button, and means for moving the button-eye and fabric into and to one side for swinging said lower section upwardly,

and for adjusting the degree of said swing ing movement, substantially as set forth.

3. In a machine for sewing shank-buttons to fabric, sewing mechanism containing a presser-foot having a concavity retaining the head of a button therein while the latter is being sewed on, flexible fabric-supporting devices in the table of the machine beneath said presser-foot, a button-hopper, a raceway conducting buttons from said hopper to the sewing mechanism having a vibratory lower section, means on said lower section for engagement with said fabric-supporting devices, whereby said section is held against lateral movement, and means for imparting verticallyreciprocating movements to said presser-foot, of successivelywarying degrees, substantially as set forth.

4. The combination in a machine for sewing shank-buttons to fabric, sewing mechanism, flexible fabric-supporting devices in the table of the machine, a presser-foot having a concavity for receiving the head of a button, button-feeding mechanism, comprisinga hopper, and a raceway having a vibratory lower.

section conducting buttons from said hopper to the fabric, a part on said vibratory section engaging said fabric-supporting devices whereby said section is guarded against undue lateral movement, means for imparting vertically-reciprocating movements to said presser-foot of successively-varying degrees, and means for swinging the extremity of said vibratory section toward the presser-foot, substantially as described.
