FEEDING MEGHANISM.

Application led May 16, 1921.

used in connection with machines for constructing st-iened fabric such as wall board, etc., and it has particular relation to that port-ion of the device which receives reinforcing strips from the chute or hopper and conveys and delivers them to the supporting backing or fabric upon which they are deposited for further treatment.

In my copending application filed on the 17th day of May, 1921, Serial No. 470,471 I designed a feeding device which is well suited for the purpose intended. The present invention is designed as another form of device which has been found particularly efective in practice.

With these and other objects in view which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention, may be varied in construction, proportions, and arrangement, withoutdeparting from the spirit and scope of the appended claims.

In order to make my invention more clearly understood, I have shown in the accompanying drawing-'s means for carrying the same into practical effect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been made the subject of illustration.

In the drawings: 1

Figure 1 is a side elevation of my device.

Fig. 2`is a plan view of the power transmission shaft and its connections for operating the feed for the reinforcing strips, showing also in section the vert-ical supports extending up from the main frame of the machine upon which the transmission shaft is mounted. c

Fig. 3 is a plan view of the conveyor and feed, showing the sprocket wheels and the Serial No. 470,060.

sprocket chains cooperating therewith to push the strips upon the conveyor.

Fig. 4 is a diagrammatic perspective view of the chute with reinforcing strips therein.v indicating also diagrammatically the lugs or flights upon the sprocket chains as they travel past the chute and push the lowest strip into position over the slot in the bottom whence it falls into its proper position upon the conveyor.

Fig. 5 is a detail enlarged view of the right hand sprocket wheel and adjusting mechanism shown in Fig. 1.

Upon the main frame of the machine (not sh wn) are located vertical supports 2, one on each side, with a transverse bar 3 connecting together the two vertical supports. Said bar acts also to support a platform or table 4 over which the conveyor travels.

Mounted on the vertical support 2 and attached thereto by bolts 6 is a bracket 5 from which extends a curved arm 8 (see Fig. 2), whose free end supports a bearing 9, for the shaft 10 extending transversely of the machine. 0n the other side of the machine is a similar bracket 5', from which extends a similar arm 11 whose free end supports a bearing 12 through which said transverse shaft 10 extends. The farther end of shaft 1() is mounted in bearings 13, adjacent which and secured upon the shaft is a pulley 14.

One end of the shaft 10 is provided with a toothed pinion 15, which intermeshes with a. like pinion 16 upon a vertical shaft 17,

` the lower end of which rests in a bearing 18 Secured by bolts or rivets 31 and ex.-y

tending towards the right from the vertical support 2 are two U-shaped arms or members 24 and 25, and mounted so as to be capable. of horizon-tal movement therein are caps 26 and 27 forming bearings for the ends of a stud shaft 29. Upon said shaft and revolving with it is the sprocket wheel 23. Secured by bolts 31 to each ofthe members 24 and 25 is a yoke 32 formed with a boss 35 which is apertured to receive an adjusting bolt 4l.

Suitably fixed on the caps 26 and'27 and extending outwardly therefrom in the same plane are bolts 36., the outer ends of which are adapted to pass through apertures in lugs 36 of a metallic strap 37, shaped similarly to the yolre member 32. The outer end of the stra-p 37 has a screw threaded aperture 40, located opposite the boss 35, and by revolving the screw 41 therein, the sprocket wheel and the stud sha-ft upon which it is mounted can be shifted towards or fromthe support 2 and the sprocket chain 4l correspondingly loosened or tightened.

Each of the caps 26 and 27 are provided with apertured ears 26 and 27 and each of the lugs 36 is provided with an eye 28 .l and between the ears and the lugs is in! serted a coiled spring 28 the ends of which extend through the eyes 28 and the apertured ears 26 and 27. The purpose of the spring is to afford a resilient connection between the stud shaft 29 and the adjustable strap 37.

As the sprocket wheel 60v on the opposite side of the machine is mounted for horizont-al adjustment in a manner exactly similar to the sprocket wheel 23, furtherdescription thereof is considered unnecessary.

Referring again to the shaft l0 the upper part of Figure 2 shows the connection of this shaft on the farther side of the machine with its source of power.4 As will be seen in said figure the pulley 14 is con-v nected by means of a belt 42 to a pulley 43 upon the shaft 43 mounted in bearings 44 and 45. The pulley 43 by means of a belt 46 is connected to a pulley 47 mount ed upon a shaft 48, which receives its power from any suitable source. The short transverse shaft 43 on the end adjacent to bear- `ing 44 is provided with a pinion 48- engaging an intermeshing pinion 49 mounted upon the lower end of the vertical shaft 5() similar' to the pinion 16 on the other side of the machine. The mechanism just described drives the sprocket 50 (Fig. 3) o-n the opposite side of the machine and its companion sprocket wheel 60 to theleft by means of the sprocket chain 51, it being understood that while the respective sprocket chains travel in the same direction on opposite sides of the machine, the edges adjacent the reinforcingstrips are traveling in opposite directions.

Mounted upon the main frame of the machine and extending transversely and obliquely across thel same is a chute or hopper 52 plainly seen in Figs. l and 3. The base plate 53 of this chute and the manner of aligning the strips 54 therein with respect vto the slot 54 in the base is best shown in Fig. 4.

line from end to end when it falls through the slot 54 in the bottom of the chute.

l(lne of the elements 58 of the conveyor 59,

is'coordinated to arrive opposite the slot 54 at the moment and the strip falls upon it and is carried along` by the conveyor to a point where it is further acted upon by the fabricating machine, of which thel Y mechanism forming the subject of this application constitutes a part. 1
