My invention is designed principally for laying the top or finish flooring over large surfaces, such as in churches, public halls,factories, and similar large floors.

Said invention consists of a machine operated by hand-power and by means of which the nails may be driven automatically at certain distances apart as said machine is moved continuously in a lateral direction lengthwise of and parallel to the edges of the boards by turning the hand-wheel of said machine, as will be hereinafter more fully set forth.

To enable others to better understand the nature and purpose of my said invention, I will now proceed to describe it more in detail with reference to theaccompanying drawings.

In said drawings, A represents the bed of Fig. 5 is a vertical section taken on j the machine, upon. which are mounted the two vertical supporting-stands B B. Between said vertical stands are arranged the large bottom gear 0 and the smaller gears D E above said large gear, each being respectively mounted upon a horizontal transverse shaft 0, D, and E, fitted to turn in suitable hearings in stands B B". To the outer ends of the upper shaft E are secured hand-wheels F F, each respectively providedwith a handle G G for turning the same. The object of having a wheel upon each side will be described later. Uponthe bottom shaft 0 are mounted the sprocket-wheels H H, which are secured to the shaft next to the stands B B, and outside of said sprocket-wheels are also secured to said shaft 0 the eccentrics 11, one upon each end, and which are fitted to turn in an opening 1 between the top and bottom plates J J 2 of frame J for the purpose hereinafter described.

Just inside of each end of the machine-bed areformed boxes A A, open at the bottom, in which are arranged transverse rolls K K, fitted to turn in suitable bearings at the ends of said boxes. Said rolls are adapted to travel overthe surface of the flooring lengthwise of the floor-boards. Upon each roll K K is respectively mounted a toothed'wheel L (see dotted lines, Fig. 5) in alinement with the sprocket-wheels H H on shaft 0', and over said toothed wheels and sprocket-Wheels are respectively arranged the endless chains M M By the foregoing construction and arrangement it will be seen that by turning one of the hand-Wheels F or F the rolls K K will also be turned through the various connections described, and the whole machine is thereby moved laterally over the floor. Said operation at the same time causes certain devices on said machine to be automatically operated for clamping each floor-board up tight against the edge of the flooring already laid and also for driving the nails therein at equal distances apart to fasten them after having been thus clamped in position.

In laying the floor-boards they are first placed in position by hand in advance of the machine, with their grooved and tongued edges fitted together and their ends abutting. The machine then follows and clamps said boards up tight in position and drives the nails therein automatically, as aforesaid. They are thus automatically clamped in the following manner: Upon the side of the large gear 0, near its periphery, is formed a cam projection N, which as the gear turns impinges against a cross-bar O and forces it longitudinally to one side. The ends of said cross-bar are secured to longitudinally-operating slide-bars P P, fitted to slide in bed A, and'the outer ends of said slide-bars carry horizontal friction-rolls Q, adapted to bear against the edges of the floor-boards. Therefore it is obvious that when the cross-bar O is forced longitudinally to one side by the cam projection N, as aforesaid, said frictionrolls are likewise moved in the same direction and force the board being laid up tight against the one previously laid and nailed in position ready to be also nailed in place. The slide-bars P P and parts connected therewith are drawn back after each movement imparted by the cam projection Nby means of suitable springs P P, attached at one end to said bars P P and at their other ends to some fixed point on the machine. The last board laid having been clamped in position, as aforesaid, it is nailed down while itis still clamped by means of devices which automatically feed and drive the nails as the machine is continuously moved laterally forward on its carrying-rollers K K',as previously described. Said nail feeding and driving devices are constructed and arranged to operate in the following manner: The feed devices R, of which there are three shown in this instance upon each side of the machine, each comprise a hopper m for holding a quantity of nails, a 1ongitudinally-corrugated cylinder n, arranged in a suitable chamber under said hopper and mounted on a shaft 17., fitted to turn in suitable bearings, and a ratchet wheel 0 and pawlp for operating said cylinder 91. An oblong opening q is formed at the bottom of hopper m, through which the nails one at a time discharge from said hopper onto the corrugated surface of cylinder n, one nail dropping into each longitudinal groove or corrugation n as said cylinder is intermittently rotated. It is thus kept filled around one-half of its periphery, and as each groove or corrugation arrives at the bottom the nail lying therein drops down therefrom onto the downwardly-inclined interior surface '1' with the drive-point of the nail pointing downward, and in this position slides down through the guideway s'to the edge of the board, as is indicated in Fig. 6 of the drawings, ready to be driven by the driver 25 or 25.

The cylinder 11 is turned, as aforesaid, to carry around the nails and intermittently deposit them one-after another into the guideway or chute s by the operation of one or the other of the eccentrics I I, which cause the vertical pawls p p to be elevated and lowered, through suitable connections hereinafter described, and thereby turns its respective ratchet-wheel 0 or 0, which is mounted on the same shaft 12. as cylinder 71. The eccentrics I I not only impart the power to turn cylinders n, but also to operate the naildrivers t t. The means for supporting said nail-drivers and the pawls for operating the cylinders 11. are difierent upon one side of the machine from those upon the opposite side of said machine, for the reason that in laying and nailing down the first few boards of the flooring it is necessary to place the machine upon the under or lining floor, close to the wall or partition, and drive the nails into the flooring being laid between said machine and said wall or partition in a direction inclined outward from the machine, as is best shown in Fig. 6. The floor-boards are fitted and the nails driven therein with the machine in said position until sufficient flooring has been laid for the machine to rest upon it. Said machine is then moved onto the top flooring already laid, with the feed devices and naildrivers just over and forward of the outside edge of the last line of boards laid. The nails are then driven at an incline, pointing inward toward the machine, as is also shown in said Fig. 6. In order to thus drive the nails outward from the machine upon one side thereof and inward upon its other side, it is obvious that the supports for the nail drivers 25 must be different upon one side from those upon the other side, as aforesaid. The driver t, which points outward for driving the nails into the boards next to the wall or partition, is mounted upon a carriage S, fitted to slide up and down on stationary inclined guide-rods S S. Said carriage consists of the top and bottom horizontal plates to 'u and sleeves to w, attached to said plates 11. o and fitted to slide on the guide-rods S. The drivers t are each pivoted at their upper ends to the outer edge of the top plate u, and each passes through a guide-opening v in the plate 1). The bottom end of each driver works up and down in an inclined guide-opening s, which is made at the proper incline to drive the nail into the edge of the floor-board just above its tongue, as is shown in Fig. 6. The top plate u constitutes a part of the bottom plate J of frame J. Therefore when said frame is elevated and lowered by its eccentric I the drivers t are moved up and down endwise with quick intermittent movements to drive each nail passed down under the end thereof. Each pawl 19 is attached at its lower end to the plate 42, and consequently when the carriage S is moved up the upper end of each pawl engages with its respective notch in the ratchet-wheels 0 and turns the same one notch forward, which is just sufficient to move each cylinder n the distance between one nail-groove and the next.

In practice it will be understood that the various parts are constructed and adjusted so as to feed each nail into position to be voasos driven just after the floor-board hasbeen clamped in place and just prior to the driver descending to drive said nail.

All the pawls p and drivers t upon one side of the machine being attached to the same carriage S they of course operate togetherin feeding and driving the nails. In this, instance three of said feed devices and drivers are shown upon each side of said machine,as previously stated; but, if desired, a greater or less number may be employed in practice. The feed devices R upon the opposite side of the machine from feed devices R are made and operate to feed the nails substantially in the same way as said devices R; but the supports for the nail-drivers t are different from those of the nail-drivers t. In this instance levers T T, pivoted at T T to a fixed bearing and carrying the cross-bar T on their outer ends, are employed instead of the carriage S, as in the other instance. The drivers 25 are pivoted to said cross-bars T and the upright pawls p are secured-to another cross-bar T on said levers T T. The inner ends of said levers T T are each pivoted to the ends of short linksU U, which are in turn pivoted to studs U U, secured to the ends of vertically-reciprocating frame J. By the above construction it is obvious that when said frame J is elevated by its eccentric I the outer ends of the levers T T are depressed, and thereby cause the drivers t to be moved down to drive the nails, and when lowered said drivers are drawn up again into the position shown in Fig. 6.

As previously described, the whole machine is moved bodily along the floor upon the long rollers K K when moving in the direction lengthwise of the floor-boards to nail the edges of each succeeding line of boards laid; but at times it is necessary to move said machine in the opposite direction or crosswise of the boarding to adjust the same into the proper position to bring the feed devices and naildrivers where they should come to properly perform their offices as the machine is fed along by the operation of the hand-wheels F F. It is also convenient to be able to move the machine in diiferent directions intransferring it from one position to another in using the same. independent device, one upon each side of the machine, operated by hand for thus moving the machine in directions at right angles to the movements imparted by turning the hand-wheels F F. As both devices are alike, it will be unnecessary to describe but one, which is constructed and arranged to operate as follows: To the bed of the machine is socured a bearing V, in which is fitted an cecentric V, pivoted to a transverse bolt V Under said eccentric andvertically in alinement therewith is arranged a carriage W,having small wheels W mounted thereon. Said carriage is arranged looselyin arecess in the under side of bed A, being held in place simply by two springs W W so as to keep the I have therefore provided an wheels W elevated a little above the floor. From the top of said carriage a bearing-hub W extends up to the periphery of eccentric V. Therefore when said eccentric is turned in one direction the carriage is forced down to bring its wheels W onto the floor, and when turned in the opposite direction, the pressure being released, said carriage and its wheels are forced up again by the springs WW into their normal positions off of said floor. The eccentric may be thus turned by means of a suitable bar W one of whose ends is adapted to be inserted into a radial opening in the periphery of the eccentric. By thus turning the eccentric and forcing the car riage-wheels W onto the floor the weight of the machine is by additional power on the bar W raised and transferred from the rollers K K to said wheels W, so that it may be moved thereon. The operation of swinging the bar W over to depress the carriage and its Wheels, as aforesaid, also causes the machine to be moved over the floor through the crank-arm X, connecting-rod Y, and barbed shoe Z. The crank-arm X is secured at its inner end to one end of eccentric bolt V and to its outer end is pivoted the connecting-rod Y, which is fitted to slide in a fixed guide-bearing Y. The shoe Z is pivoted to the outer end of said connectingrod and is adapted to bear upon the floor and hold thereon by means of its spurs Z when pressure is applied against the same to move the machine in the opposite direction. In practice it will be understood that when the handle of barW is moved in the direction indicated by the arrow in Fig. 2 the eccentric first forces the wheels W down and transfers the weight from the rollers K K to said wheels W, and immediately following said transfer the poweris transmitted through the connections described to the shoe Z, and the machine is thereby moved. Only short movements in this direction are necessary in the operation of the machine, said machine being arranged to travel principally on the rollers K K, as hereinbefore described. In moving the machine by the bar W it is done by short hitchesthat is, by swinging said bar forward and back, so as to alternately engage the shoe Z with the floor and move it back again into position for each intermittent forward movement of the machine.

In operating the machine in practice, after the first few boards have been laidacrossthe room or hall next to the wall-or partition, the feed devices, nail-drivers, and their connections with the driving power may be removed from the machine before adjusting said machine onto the top flooring preparatory to proceedin g with the floor-laying over the balance or main part of the floor-surface, and thereby considerably lighten the weight of the machine, or said parts may be left on, as preferred.

The right is reserved to make such modifications in the construction of the machine as circumstances may require and comin g within the scope of my invention.
