6 Claims.

This invention has to do with a nail driver and it is a general object of the invention to provide a simple, practical, dependable and eieetive mechanism that is easily transportable and which serves to drive or apply nails, spikes, or like articles.

There are numerous situations where nails or the like are to be driven and where the usual driving by means of a hammer becomes a tedious and laborious task.

A general object of the present invention is to provide a simple, compact, manually portable device serving to handle a supply of nails and operating to drive the nails one at a time without requiring appreciable exertion on the part of the user.

Another object of the invention is to provide a device of the general character referred to in which the driving action is gained through a mechanism, preferably a cam mechanism operated by a small prime mover such as an electric motor.

It is a further obpect of this invention to provide a mechanism of the general character re ferred to which operates to deliver uniform blows at uniform intervals of time and which is such that the blow delivered may be adjusted or varied as circumstances require.

Another object of the invention is to provide a mechanism of the general character referred to including a driving device and means supplying nails thereto so that a quantity of nails can be stored in the device to be driven one at a time as the user desires.

The mechanism of the present invention involves, generally, a cylinder with a plunger therein. A driver is carried by the plunger and projects from the lower end of thecylinder to operate in a guide and a shock absorber limitsthe operation of the driver. A drive spring is carried in the cylinder and operates theplunger and a cap on the upper end of the cylinder is adjustable to vary the'action of the spring and the cap also serves as a mounting for a handle to be conveniently grasped by the user. Elevating means operates to lift or elevate the plunger against the resistance of the spring and is preferably a cam means involving a revolving cam sleeve around the cylinder. A drive for the cam sleeve involves an electric motor and a Worm gear mechanism between the motor and the sleeve. The cam mechanism is such as to lift or elevatev the plunger gradually and at a uniform rate and to liberate it suddenly to be driven downwardly under the action of the spring.

A supply means carries nails to be delivered to the guide in which the driver operates and may include a magazine in which nails are held. In a typical case the magazine may be helically formed and the nails may be advanced by a tape arranged in the chute and operated b y a spring motor or the like, the tape having a follower attached thereto to act on the nails in the chute.

A feed handles the nails from the magazine and delivers them/ to the guide and may involve a star wheel advancing the nails one at a time and a pusher synchronized with the star Wheel to push the nails one at a time into the guide. A check pawl prevents over-feed of the nails and a drive preferably synchronized with the action of the plunger operates the star wheel and the pusher.

The various objects and features of my invention will be fully understood from the following detailed description of a typical preferred form and application of the invention, throughout which description reference is madek to the accompanying drawings, in which:

Y

'I'he mechanism provided by the present invention involves, generally, a body A, a plunger B operating in the body, a driver .C carried and operated by the plunger, a guide D carried by the base portion of the body and guiding the driver, a shock absorber E cushioning over-travel of the driver and plunger, a drive spring F carried by the body and operating the plunger, elevating means G- operating to elevate the plunger in the will be hereinafter body and suddenly releasing it to be driven by the spring, power means H, preferably in the form of an electric motor, drive means J from the power means to the means G, means K supplying nails and advancing means L operating to receive nails from the means K and deliver them one at a time to the guide in which the driver operates.

The body A in its preferred form involves an elongate cylinder Il), closed at its lower end by a base II and at its upper end by means of a cap I2. The cylinder is preferably round in cross sectional configuration and the base I I provided at the lower end of the cylinder is preferably joined thereto as by a threaded connection such as is shown in Fig. 1 of the drawings. Through the construction provided the base is rigid with what may be considered the lower end of the cylinder and serves as a mounting or carrier for other elements of the structure, as described. The cap I2 is preferably attached to the upper end of cylinder I as by a threaded connection I4, and a suitable screw clamp I5 is provided for setting the cap against movement or rotation on the upper end of the cylinder. In the particular case illustrated the threaded portion of the cap is split at I6 (Fig. 1l) and the clamp I5 is carried by the split portion of the cap and has an operating knob I'I dle I8 is carried by or is provided to project from the cap so that it extends transversely of the cylinder and is located above the upper end of the cylinder providing a part that can be conveniently gripped by the user of the structure.

The plunger B is slidably carried in the cylinder l and in practice may be a simple body or block of suitable metal of such size and shape as to have considerable mass.

The driver C is carried by and depends from the plunger B so that it projects downwardly through an opening 2li in the base E and enters the guide D which depends from the base.l The driver is shown in the drawings as an elongate member of suitable size or diameter and it is shown releasably joined to the plunger by a threaded connection 2I so that it can be replaced or renewed as circumstances require. In the preferred arrangement the driver is located centrally of the plunger or so that it is concentric with' the mechanism generally. A shock absorber E, preferably a body or block of rubber or like material, is provided in the cylinder I to occur within the base II and beneath the plunger B. The shock absorber serves to cushion movement that might be considered over-travel of the plunger and thus prevents undue shock or hammering occurring between rigid parts of the structure.

The drive spring F is carried in the cylinder I0 between the upper end of the plunger B and the cap I2 and in the preferred form of the invention it is a heavy, helical spring that operates under compression. In the particular form. of the invention illustrated the plunger B has a central vertical extension 26 projecting upwardly into the lower end portion of the spring F. The extension 26 serves to add mass to the plunger and it also serves as a guide centralizing the spring in the cylinder.

The guide D is carried by the base portion of body A and depends therefrom. The guide has an elongate tip portion 30 extending downwardly a substantial distance below the base II and it has a central opening 3| in which the facilitating its operation. A hanportions 40 and 4 driver C operates. The upper end portion of the guide is provided with a side or lateral nail receiving opening 32 which opening is of such vertical extent as to readily receive nails so that they enter the guide to be positioned ready for driving by means of the driver C.

The elevating means G operates to lift or elevate the plunger B against the resistance of spring F and in the preferred form of the invention it c is a cam means. In the particular case illustrated the cam means that elevates the plunger involves a rotating cam member 35 in the form of a sleeve surrounding the cylinder Iii and a follower 36 projects from the plunger B and cooperates with a suitable cam opening in the sleeve. In the case illustrated in the drawings the cam sleeve 35 nts around the cylinder III with suitable clearance and is supported for rotation relative to the cylinder by suitable bearings 38.

Ihe cam sleeve 35 is intended to rotate, for instance, at a uniform or consistent speed when the mechanism is in operation, and the cam opening or cam faces provided thereon may be such as to impart any desired motion to the plunger B through the follower 36 which projects from the plunger. In the case illustrated the cam faces or parts of the sleeve 35 are such as to elevate and release the plunger once for each rotation of the sleeve. The nature of the cam slot or groove provided in the sleeve 35 is illustrated in Fig. 8 where it will be seen that the cam slot has an inclined or helically pitched portion 4E! that extends substantially 360 around the interior of the sleeve and a vertical or longitudinal` portion 4I which extends between and connects the ends of the helical portion 4U which are spaced a substantial distance apart longitudinally of the sleeve by reason of the pitch of portion 8.

The follower 35 projects from one side of plunger B and is shown provided with an antifriction member or roller 135 which operates in the cam groove provided in the interior of sleeve 35. The roller I5 is so proportioned to the cam 4I as to operate freely through the cam groove. The cam follower 36, in extending from the plunger to the cam groove in sleeve 35, extends through a vertical or longitudinal guide-way in cylinder Ii). The cooperation of the follower with the guide-way 5d holds or maintains the plunger B against rotation relative to cylinder IQ while at the same time it allows for free full longitudinal movement of the plunger in the cylinder.

In thepreferred form of the invention a housing or jacket 53 is provided to encase the mechanism just described. The particular housing 53 shown in the drawings is carried by and projects upwardly from the base I I and its upper end portion rits closely around the earn 35, as clearly shown in Fig. 1 of the drawings. The motor H is preferably a typical or simple electric motor such as is commonly used to operate hand tools of the general character under consideration. In the case illustrated the motor I-I is shown mounted on the` upper portion of the housing 53 at the exterior thereof. A suitable power line III) is shown connected with the structure for energizing motor H and a handle I I I is shown on one side of housing 53 projection from a point where a suitable switch S is located. An operating trigger II2 for the switch is located at handle III.

The drive J from motor I-I to the cam sleeve 35 may be any suitable mechanism that will result in the desired rotation of the cam sleeve when the motor is energized. In the form of the invention illustrated the means J involves a worm gear 55 on a shaft 56 supported in the housing 53 and directly coupled to and driven by the shaft of motor H. A Worm gear 51 is fixed to or pivoted on the sleeve 53 and is engaged by the gear 55. With the construction just described and which is illustrated in Figs. 1 and? of the drawings the cam sleeve 35 rotates at a suitable speed when the motor H is in operation.

The means K provided for supplying nails to the driver and guide may be any suitable structure or device that will serve this purpose. In the particular case illustrated the means K involves a magazine that carries a supply of nails and which is made up, essentially, of a helical chute 60. The chute is carried by the .base portion of body A and surrounds the upper end portion of the guide D and is located so that .it is generally concentric with the guide. The outer Vend of the chute .is open to receive nails and the inner end of the chute is open to or communicates with the feed L so that vnails are supplied thereto for delivery into the guide.

The particular chute illustrated in the drawings has an upper channel 6| carrying the heads 62 of the nails N and it has .a lower channel 63 which carries the shanks or body portions 64 of the nails. Advancing means serves to operate the nails in the chute, and in .the case illustrated this means involves a follower 65 located in the chute outward of the nails and operable in the channel 63 of the chute to press or urge the nails inwardly or toward the inner end of the chute. A handle 65a (Fig. 10) depends from follower 65 through a slot 65h in the bottom of the chute 60 so the follower lcan be operated manually. A tape or flexible band 66 is attached to the follower 65 and extends through channel 63 of the chute. The tape emerges from one side of the chute at the inner end portion thereof and enters a suitable winding device -61 which may be a spring operated device tending to normally yieldingly operate the tape in the direction indicated by the arrow in Fig. 6.

In the particular case illustrated the tape as it extends through the chute may engage or bear upon nails in the chute in which case a suitable support or nail slide 68 is provided in the chute opposite the point where the nails are engaged by the Vtape 66, see Fig. 9 of the drawings.

The adjacent convolutions of the chute 60 are preferably fixed or secured together as by welding W or the like, and the unit formed by the chute is detachable from the base l'l. The mounting means releasably securing the chute to the base is shown as involving an apertured bracket |20 on the upper side of the chute receiving a lug |2| projecting laterally from one side of the base. A simple spring-pressed latch bolt i 2 Ia is carried by the chute and engages an `opening |22 in the base diametrically opposite the lug |2l.

The feed means L provided by the invention serves to feed nails from the supply means K to the guide D, and in .accordance with the broader principles of the invention it may be any suitable mechanism that will serve this purpose. In the case illustrated .the feed means L involves, generally, a star wheel 7.0 (Fig. A6) designed to engage and advance the nai-ls .in a channel 'H which continues laterally from the lopening 32 provided in the side of the guideway. A pusher I2 engages nails advanced tor fed, by the wheel and a side of the guide D. The star wheel 'l0 is mounted on a vertical axis or so that its axis is parallel with that of the nails carried in the channel 1| and upon intermittent operation of the star wheel through suitable amounts the nails are advanced one at a time toward the guide D.

The pusher i2 is provided to engage the nails one at a time as they are advanced by the star wheel and acts to push the nails through the opening 32 and into the guide.k In the particular case illustrated the pusher 12 is pivotally mounted on a slide ymounted to reciprocate in .a direction normal to the longitudinal axis of the guide. A spring 0| is provided between the pivoted pusher and its supporting slide and is such as to normally yieldingly urge the pusher toward the nails in the manner illustrated in Fig. 3 of the drawings.

The check pawl 73 is pivotally supported to cooperate with the star wheel and pusher so that nails .are retained at the star wheel as the nail being fed is advanced or pushed by the pusher l2. The pawl 'I3 is supported on a fixed pivotal axis parallel with that of the pusher 'l2 and is normally yieldingly urged toward the nails `by means of a suitable spring 85.

A drive is provided for operating the s tar wheel i0 and the pusher 12 in suitable synchronism with each other and in synchronism with the plunger B. In the case illustrated the drive involves a pivoted rocker having projecting arms di and 92 operatively connected with the slide S0 and star wheel '|10 respectively. The arm Sil is slida-bly pivotally connected at 93 to .the slide t0 while the arm 92 is connected with the star wheel through a spring arm 94 that cooperates with a ratchet wheel 95 xed relative to the star wheel. A spring pawl 96 engages the ratchet wheel and checks reverse operation thereof.

The rocker 90 (Figs. 4 and 5) has a driving arm 91 projecting therefrom which is angularly related to the arms 9| and v92. A pivoted lever |00 has an arm |0| projecting into the cylinder i0 through an opening |02 and has an arm |03 to which a link |04 is connected. The link |04 connects arm `|03 with the arm 91 of the rocker 90. The arm |01 projects into the cylinder I0 so that as the plunger B reaches the upper end portion of its stroke the lever H10 is rocked a suitable amount, Vcausing the link lilll rto operate Ythe rocker .9,0 with the result that the star wheel and pusher are operated ,suitable amounts. It is to be observed that when the plunger B is at the upper end of its stroke operating the lever .|00 the driver is elevated so that it leaves the lateral opening 32 in conimunicaticn with .the opening 3| unobstructed and such as to receive :a nail vas it is advanced by reason of the operation of the pusher. As the pusher is advancing a nail into the guide B the starkwhe'el .is vadvancing la nail ready for the next operation, and the nails behind the one thus advanced are restrained by the pawl 113. A spring |04a anchored in sleeve 53 and coupled to the link |04 at the lower end thereof normally yieldingly tends to hold the mechanism above described in the position shown in Fig. l.

From the foregoing 4description it will be understood how a person using the `structure after suitably charging it with nails may introduce it with the opening 32 at the to parts to be nailed by grasping the handles i8 and Ill. To cause driving of a nail the trigger l I2 controlling switch S is actuated causing energization of motor H. When the motor is put in operation the cam sleeve 35 is rotated and through cooperation of theY cam sleeve 35 and follower 35 the plunger is elevated against the resistance of spring F. As the plunger reaches the upper end of its stroke a nail is fed into the guide D by the feed means L. When the plunger B reaches a predetermined elevated position it operates lever IBD which moves link |04 down causing the pusher l2 related to the link 104 to be operated. When the plunger finally reaches the extreme upper end of its stroke the follower enters the elongate portion il of the cam slot releasing the plunger so that it is driven downwardly by the spring F. The driver C operated downwardly by the plunger engages the nail in the drive D and drives it into the work W in the manner shown in Fig. l of the drawings. When the plunger leaves the up position the feed means L returns immediately to the unactuated position. As the cam sleeve 35 continues to rotate the action just described is repeated and between strokes of the driver the user may shift or advance the structure from one location to another so that successive nails are driven in dierent parts of the work W'.
