1'0 ctZZ whom it may cmwcrn:

Be it known that I,WILsoN HARGREAVES,a citizen of the United States, residing at Chi cago, in the county of Cook and State of Illinois, have invented a new and useful Machine for Spacing Laths, forming series of the same into the form of gates and inserting lathingnails therein, whereby the lathing of buildings may be improved and the cost reduced; and I do hereby declare the following to be a full, clear, and exact description of the invention, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention consists in the construction, arrangement, and combination of the several parts and devices that will be hereinafter described and in the method or manner of moving the several parts by which the lathe are spaced, held, and fastened in the form of gates and by which the distributing, conveying, holding, and driving of the nails into the lathe are accomplished.

In the accompanyingdrawings of ten sheets, Figure l is a front elevation of my machine with the gate of laths and several parts of the machine in the position when the nails are driven and the tray and scoop are at their lowest position. Fig. 2 is a front elevation of the upper and lower pressure-slides with the several parts in position as shown in Fig. 1. Fig. 3 is a front elevation of the upper and lower pressure-slides with the upper slide raised and the several parts in the position when the nails have been driven and the lower pressure-slide is ready to be raised from the gate by the continued upward movement of the upper pressure-slide. Fig. 4B is a side view with the several parts to the left of the upright part of the frame in the position as The opposite side of the machine is similar to and symmetrical with the side here shown. Fig. 5 is a sectional side view with the several parts to the right of the center in the position as shown in Fig. 7. Fig. 6 is a sectional side view showing the several parts of the machine raised to their highest position, at which point the nails enter the feeding mechanism. Fig. 7 is a plan or top view with the rear part of the machine in the position shown to the left of the center of sectional view Fig. 5. Fig. 8 is a sectional plan view through the line 8-8 in Fig. 5, show"- ing the gate of laths in position in the machine when the nails are driven.

Fig. 23 is a back view of the upper and lower pressure-slides as shown in position in Fig. 2, the dotted lines showing the position of the upper pressure-slide in Fig. 3. This view shows the friction-springs affixed to the lower pressure-slide, the purpose of which is hereinafter explained. The recessesin the frame A are to receive the points of the friction-springs when the positions of the slides'are as shown in section Fig. 6. When said friction-springs enter said recesses, the pressure-slide E is held secure till the downward movement of the upper slide E forces down the lower pres- Fig. 14 is a side view of the sure-slide E and moves the friction-springs out of the recesses into the position shown herein. Fig. 24. is a detail view of the sectional parts shown in Figs. 21, 22, and 6.

In the several drawings, A designates the frame of the machine. B is the bed of the machine. B is a sliding frame constructed to hold and move the laths while they are being formed into a gate and receive the nails. 1) represents stops on the frame B to regulate the widths of the gate. B represents rocking bars held in the frame B by trunnions. b represents spacingslides in the rocking bars B b represents links connecting the spacing-slides. b represents stops on the spacing -slides. 19 represents flat curved springs attached to the spacing-slides., b represents arms on b in Figs. 8, 9, and 10. The foregoing parts are particularly shown in Figs. 9, 10, 11, 12, and 13.

0 represents laths spaced and held by the spacing-slides, stops, and springs, before described, and are shown in Figs. 1, 2, 3, 8, and 9.

0 represents crossbars, of which there may be two or more, containing sharp steel points set diagonally therein, which enter and hold the laths when the bars are pressed on to form the gate, as shown in Figs. 9 and 14:.

C is a gage fixed to the bed of the machine B to form a guide for the sliding frame B. (Shown in Figs. 1, 2, 3, and 8.)

D is a presser-bar which moves vertically in the front of the frame A and is used to press the cross-bars 0 onto the gate of the laths. D is operated by the racks (Z, the pinions (1, shaft (1 and the lever (Z These parts are shown in Figs. 1, 4, 5, 6, and 8.

E and E are the upper and lower pressureslides. e represents links connecting Eand E. e represents racks fixed by their extensions to the slide E. 6 represents pinions on the shaft 6 which operate the racks e. e is a lever by which the slides E and E are operated. 6 represents rollenbearings back of the racks 6'. These parts are shown in Figs. 4, 5, and 6.

9 represents friction-springs fixed on the back of the slide E, designed to hold the slide E till the same is moved by the slide E. These are shown in Fig. 23.

6 represents pins in the slide E. F represents bell-cranks on the shaft 6 Grepresents telescopic connecting-rods pivoted to the bell-cranks F and to the tray I. H represents automatic lifting-rods, also pivoted to the bell-cranks F and constructed so as to fall of their own weight against the pins 1' on the side of the tray 1 when they are in the position shown in Fig. 5. These movements are shown in Figs. 4, 5, 6, and 7.

I is a tray in which the supply of nails is placed and is raised and lowered by the connecting-rods G and the lifting-rods H, as shown in Figs. 5, 6, 7, and 8.

'i represents the pins on the side of the trayI which engage the lifting-rods H. 1" represents straps on the side of the tray, which guide and limit the movement of the liftingrods H, as shown in Figs. 4 and 7.

J J are gravity-levers pivotallyaifixed to the under side of the tray I,the pivotal points being near the ends and to the side of the longitudinal center line of the levers. At the pivotal end of each of these levers a flat spring is affixed. The movement of these levers is limited by small stop-pins, against which the long ends of the levers fall with the rise and fall of the tray. In Figs. 1 and 4 the tray is shown in its lowest position, the long end of the levers resting against the stop-pins and the free ends of the flat springs at the short end of the levers being within the side lines of the tray. (See Fig. 1.) The levers and springs remain in this position while the tray is raised by the rods G to the, position shown in Fig. 5, at which point in the upward movement the rods H fallv under the pins '6. As the tray is raised by the rods H from the position shown in Fig. 5 to the position shown in Fig. 6 the long ends of the levers fall to the opposite stop-pins. By this movement the springs on the short ends are swung out. beyond the side lines of the tray and at right angles thereto. The levers and springs remain in this position while the tray is lowered. When the tray is part way between the highest point of elevation and the horizontal position, the rods H come in contact with the leversprings, as they project beyond the sides of the tray. From the first point of contact till the tray reaches the horizontal position the rods continue to press back the springs of the levers, which are held in position by the stoppins, against which the long end of the levers rest. As the weight of the tray is transferred from the rods 11 to the. rods G by the continued lowering of the tray the rods are drawn below, and thus released from contact with the pins 7} and are instantly forced from under and to the side of the pins 71 by the pressure of the gravity-lever springs. The levers thus freed fall to the opposite stoppins as the tray is lowered to the.position shown in Fig. 1, where they remain till the movements here described are repeated.

K is a scoop hinged to the frame A of the machine by the scoop-bar It is constructed to slide along the bottom of the tray I and scoop up the nails as the tray is raised from the horizontal position to its highest point. 7c represents slots in K, into which the nails fall and pass into the feeding mechanism of the machine. 70 represents openings in the scoop K, through which all nails not held in the slots 70' pass back into the tray. k is a bar hinged to the frame of the machine and to which the scoop is attached. L is a swinging shutter hinged to the scoop bar 70 Its purpose is to prevent the nails from jamming as they pass down the slots 7c through the openings Z in the bar 70* by partly closing the opening and by swinging out from the bar as the scoop is lowered with the tray, carrying with it as it swings all the nails resting against it back into the tray. The construction of the scoop K is shown in Figs. 4, 5, 6, 7, 18, and 19 and the swinging shutter in Figs. 5, 6, 7, and 18.

M represents guideways affixed to the frame of the machine, formingacontinuation of the slots when the tray is raised, as shown in Fig. 6.

N is a finger-bar held in extensions of the frame of the machine and free to move laterallyin front of the lower end of the guideways M. n represents fingers attached to the tinger-bar N, constructed and arranged to check the run of nails down the guideways M and to take one nailfrom the guidewayat each move ment of the finger-bar. The construction and operation of the finger-bar and fingers are shown in Figs. 1, 4, 5, 6, 7, 15, 16, and 1.7. N is a trigger attached to the rack e in Figs. 5 and 6. n is a lever pivoted on the frame A, operated by the trigger N, as shown in Figs. 5 and 6. n is a small bell-crank pivoted on the frame of the machine and connected by wires to the lever 01' and to the finger-bar N, as shown in Fig. 1. n in Fig. 1 is a spring attached to the frame A and the bar N. These several parts are constructed and arranged to operate the finger-bar and fingers.

O is an apron arranged to throw the nails as they fall from the scoop back into the tray and to prevent them from passing into the working parts of the machine, as seen in Figs. 5 and 6.

P (shown in detail in Figs. 15 and 16) represents tubes firmly fixed to the frame A, each of which tubes has an opening near the top in line with the guideways M, which lead into them. In front of these tubes and through openings in the ends of the frames of the guideways M the fingers it pass and op-- crate so as to allow one nail at a time to pass into the tubes P.

Q, represents funnels attached to the bar g, which is hinged to the links 6, attached to the slide E. When raised, they form a continuous connection with the tube P. Their lower ends q are partly closed by the lips g which catch the heads of the nails as they fall. These parts are shown in Figs. 1, 5, 6,21, 22, and 24:.

R represents driving-bars attached to the upper pressure-slide E, constructed and arranged to descend behind the funnels Q, forcing the lips of the same from the heads of the nails and driving the nails into the laths C. The construction and operation of these parts are shown in Figs. 2, 3, 5, 6, 21, and 22.

S represents spring-cams affixed to the slide E, their position, construction, and operation being shown in Figs. 1, 2, 3, and 8.

T represents nail-holders pivoted on the lower pressure-slide E, so constructed and operated by the cams S as to hold the nails against the pins 6 on the slide E while the driving-bars R are forcing the lips of the funnel Q from the head of the nails and while they are being driven into the laths, as shown in Figs. 1, 2, 3, 20, 21, and 22.

The operation of the machine is as follows: The machine being placed in the position as shown in Fig. 4, a quantity of nails is put in the tray 1. The lever e is moved to the right, thereby operating the shaft 6 and the bell crank F, lifting the rods G and tray I and drawing down the rods H, which fall against and engage the pins t' in the sides of the tray I. Then in horizontal position, as shown in Fig. 5, the lever 6 being moved from right to left raises the tray I by the rods H to the position shown in Fig. 6. While the tray I is being thus raised by the rods H, the scoop K moves along the bottom of the tray I underneath the nails therein, and as the tray and scoop rise to the position shown in Fig. 6 a part of the nails falls into the scoop-slots 7t and the rest back through the openings 70 in the scoop K back into the tray I, (see Fig. 7,) the apron 0, Fig. 6, preventing them from falling into the other parts of the machine. As the lever e is again moved from left to right, drawing down the rods H and lowering the tray 1, the sh utter L swings from the scoopbar as shown in Fig. 5, throwing back all nails which may have been jammed in front of the opening Z in the scoop-bar k During the upward movement of the tray I from the position shown in Fig. 5 to the position shown in Fig. 6 the gravity-levers J fall toward the lowest part of the tray 1, the springs attached to the short ends of the levers projecting beyond the sides of the tray I, the reverse of the position shown in Fig. 1; As the rods H and the tray I are lowered these springs come in contact with the edges of the rods H and are pressed back by these rods till the position shown in Fig. 5 is reached, where the rods H are drawn a little below the pins t' and the pressure of the gravity-lever springs throw the rods H out of line with the pins 71 and allow the tray I to be carried down by the rods G to the position shown in Fig. 4, in which position the gravity levers and springs are entirely within the lines of the sides of the tray, as shown in Fig. 1. They remain in this position till the tray is lifted again to the horizontal and the rods H again engage the pins t' and lift the tray to the position shown in Fig. 6. When the tray I and scoop K are lifted to the position shown in Fig. 6, the nails which fall into the slots it slide downward, and as they approach the shutter L and scoop-bar 70 they are brought into a steady and npright position head up by the peculiar bevel on the inside of the slots 70. (Shownin section in Figs. 18 and 19.) Thus steadied, the nails pass under the shutter L, through the openings Z in the scoop-bar k and down the guideways M, which are continuous with the slots it, till they are stopped by the fingers n on the finger-bar N, as shown in Fig. 15. WVith the nails held in check in the gnideways M by the fingers n and the several parts of the machine being in position as shown in Fig. 6 a movement of the lever e to this vertical movement of the racks, slides,

and funnels the trigger N trips the lever 02, the movement ofwhich communicated by wire connection and small bell-crank n to the finger-bar N moves it laterally to the right, the spring a drawing it back to its first position. In this lateral movement of the finger-bar the first fingers are withdrawn from the nails resting thereon, allowing them to fall on the lower or second fingers. The return movement of the bar N brings the first fingers between the first and second nails, (see Fig. 15,) checking them, while the second fingers are withdrawn from the first nails, which drop into the tubes P and through the funnels Q to the end q, where they are held,

as shown in Fig. 6 and in detail in Figs. 21 and 24. The feeding mechanism described operates with every movement of the lever e from right to left, while the scoop supplies the nails to the guideways M but once whenever the lever e is moved from left to right twice. The machine thus supplied with nails and in position as shown in Fig. 6 is ready for driving the nails into the laths. These are placed on the sliding frame B between the stops b and springs 5 the series of laths being forced within the stops b, as shown in Fig. 9. When thus spaced and held by the stops and springs in the rocking bars B the cross-bars O are placed across the laths C and the slide B is moved under the presser-bar D, which, operated by the lever (1 racks cl, pinions d, and shaft d presses the steel points of the cross-bars G into the laths. These steel points being set in diagonal form hold the laths firmly in the form of a gate, as shown in Fig. 9. The laths thus spaced and held on the sliding frame B and by the crossbars 0 are moved into position to receive the first series of nails. When thus ready, the nailing mechanism and feeding tubes and funnels are as shown in position in Fig. 6 and detail Fig. 21. The movement of the lever 6 brings the pressure-slide Edown till it rests on the lower pressureslide E, the latter being held in place by the friction-springs, which press into the depression in the frame A, Fig. 23. In this movement the cams S force the nail-holders T against the nails, pressing them against the pins 6, Fig. 2, thus holding the nails firmly while the driving-bars R are passing down behind the funnels Q, moving them outward away from the nails, as shown in Figs. 6, 21, and 22, till the bars R rest on the heads of the nails, as

in Fig. 22. The continued downward movement of the pressure-slides E and E forces the nails into the laths, as shown in Figs. 1, 2, and 5. The next movement of the lever e from right to left first raises the pressureslide E, with the driving-bars R and cams S. The latter striking the upper incline of the nail-holders T move their lower ends from the nails, as shown in Fig. 3, the lower pressure-slide E remaining in place, hold by its own weight and the resistance of the frictionsprings 6, Fig. 23, till it is lifted by the links e and raised to the position shown in Fig. 6, at which point the sliding frame is moved into position for the next series of nails, which are driven by again moving the lever e from left to right, as before described. When the several series of nails have been driven into the laths, the sliding frame B is drawn from beneath the pressure-slides E and E to the front extension of the bed of the machine B. The arms 12 of the rocking bars B are pressed down, raising the edge of the rocking bars on their trunnions, releasing the gate of laths from the stops and springs, and the gate thus formed and prepared with nails is set aside ready for the lather. These gates of laths are arranged in packing-frames constructed for their safe and quick conveyance from the nailing-machine to the rooms or building where they are required.
