NAILING m onmn.
My present inyention relates to machinery and more particularly to 'nailingmachines and has for its object to improve thedriving mechanism of these machinesin such man'- ner that it will be self adjusting When perating upon work pieces ,of di'fierent' thicknesses Whereas it" has'hitherto' been necessary to make fixed adjustments of thenailing mechanism for each thickness of work or else raise the thinner pieces on the table of the machine. This'in ention is 'anhimprorement upon that shown in'myprior copending application- Serial Number 601,433 filed Noyember' 16, 1922, and it hasfor a further object to p'rovi de an improved Working relationship between the driverv and the nail chuck by rendering'the latter self adapting to the 'Work piece. 'To these'and other ends the inyention'resides in certain proveinents and combinations of parts alias will be hereinafter niore'fully described,'the novel features being pointed out the claims at the end ofthef 'specification.
In the drawings:

Similar reference nume'rels throughout theseve ral views indicate the same partsi The improvements are shown embodied in a nailing machine of a familiar type which 1' indicates the erticalsidje Ltra me provided "With .Ways 2 upon'Whichrecipro- H W I pheightibQf -the end piece; to turn these two 'oyfer' and thenapply the other top' and'nail it are greater h'eight or atone to Which its cate yertically the guides idiot the crossflhead i L constituting the driving head of the {driving mechanism. The head'i's reeiprocated Vertically by a pitman 5 connected to it by a wrist pin 6 and actuated by mechanism which does'not concern the present i'n 'en} tiohi Secured tothe front of the frame beneath the driving head is'a table"? for the Work which in the present embodiment and description We Will assume tobe boxes. Immediately above the table there is mounted en "the ifranie 1 by means of adjustable brackets 8, cross bars 9 uponwhioh the cast legs 10" containing the nail chucks are seheadt is adjusted by means not shown to carry the driver 14; on the driving stroke lust iar enough out of the mouth of the chuckto set the nail head the desired disin' the ork piece." f lkleret'ofore it has been necessaryito have thesurface in which u 'jnan isfdriven always inthe same plane for a given adjustment of the nailing mechan smbecausevthegdriyer was positivelydr'i'v- 'en on a 'setstroke and-1t WouId'not drive the'j'nails' and is et them uniformly in the Work unless this condition obtained. Therefore, in" cOnstifuctinQ'abox oi. the nature shown at ALin Figurese and 7' it was necessary/in first nailing one of the topsB to the ends C, to place the other unnailed top D beneath the said end to bring the surface of v13 up high enough for thedriver. The
boxwas then turned oyer'to the position of said iigures andthe top D neiled'inplace With the surface thereof in the same plane previously" occupied that of the top D. This, however, necessitated holding the three loose pieces together in a sort of balanced relationship on the table While the prelimi- "nary nailing was being done Which Wasdiffic'ult inconvenient, the manipulation of the un-nailed top during the nailing of'the other resulting in considerable lo'ssoftinie.
is obviously 'mucheasiei tEor the operator ,to merely place the end C edge "Wise on the t'able7;nai1 one top piece to it'at the h'eight o f its own thickness plus the following reasons:
Instead of mounting the driver 14 in fixed relationship to the driving head-4, 1 provide the latter with a hollow, tubular guide casing formed with lug 16 at its top by ineansof which it is retained in the head by the usual transverse locking bar 17. Inside. of this guide case is a block or head 18 to which the driver 14 is rigidly fixed and which comprises cylindrical extension 19 having a further bearing for limited sliding movement in the bottom of the case through which it projects. The, upper end of the guide case is closed by an adjustable threaded plug 20 having a cupped interior and interposed between this plug and the head 18 "of the driver is a compression spring 21. It 'will thus be seen that the driver is capable of yielding and that the driving head presses the driver downwardly only through the medium of this spring 21. i
The chuck 10 is of the usual split yielding type with spring jaws 22 through which the nail is forced by the driver after being deposited in the feed channel 23 from the nail tube 24. It is mounted for limited vertical reciprocatory movement on the supporting bars 9 for which purpose it is fitted with an offset guide strap. 2% embraced by a'yoke 25 (Figures 2 and 4) on a casting 26 that receives the bolt'll previously referred to. lVithin this casting 26 i s a spring socket or chamber 27 containing a. spring 28 resting on a plug 29 at the bottom and reacting at its upper end Where it pro ects from the casting against the shoulder 30 on the chuck recessed to receive'it as shown. The tendency of this spring 28 will be seen to be to hold thechuck raised on the supporting bars, the yoke 25 engaging a shoulder 31 on. the chuck to limit its movement. The chuck can be forced downward against its spring 28 by engagement of the projectlug-portion 19 of the driver head with the top surface thereof as shown in several of the figures, the spring 21 of course being superior tothe spring 28. hen so cooperating and the driver and the chuck descend together the point of the driver projects just far enough from the mouth of the chuck to set the nail below the surface of the work as the chuck rests on that surface. The operation is as follows:
The driver carries the. nail through and out of the end of the chuck in the usual manner. The stroke of the driving head 4 is adjusted to advance the driver, without compressing the spring 21, a maximum distance that will just'drive the nail home on the lowest working surface. Such surface would be presented in nalling the first cover ent elevations.
on the end piece C, the cover D being absent. The two angled pieces B and C re then turned over and the cover is applied as in Figure 6 which raises the working surface a distance equal to its thickness. Upon this stroke of the head and driver the mouth of the chuck 10, nevertheless, strikes the surface of the work and halts the driver 14; so that it drives and sets the nail only as far as the driver projects beyond the abutting end of the chuck. The rest of the normal travel of the driving head 4 is not effective upon the driver but is taken up by the compression of the spring 21. Of course the latter must be sufliciently strong to drive the nail without yielding until the chuck abuts the work but not strong enough to cause the chuck to injure the work, such iii-- jury being further provided against by giving sufficient area to the lower end of the chuck. Upon the return of the driver the chuck 10 follows it back under the influence of its own spring 28 the limited distance of its own travel in order to clear the next: work piece to be placed on the table the general idea being that when the driver and cnuck come down together the chuck is carried into engagement with the work and halts the driver at the proper point with a large enough bearing 011 the work to cause remaining movementof the driving head to be taken up by the driving spring 21.
The respective maximum and reduced strokes of the driver in another contingency are shown in a comparative way in Figures 2,.and 3 both of which show the driving cheadf l at its lower limit of movement as evidenced by its same position in the two figures while in the two cases the driver has completed its nailing stroke at two differ- Considering also Figure 1, in Figures 1 and2 a relatively thin element E is being nailed to an element F while in Figure 3 a relatively thicker element G- is being nailed to the same element F. Note that in Figure 2 the spring 21 has not been compressed at all while in Figure 3 it is partially compressed.
The yielding nature of the driver of my invention is also useful in preventing injury to the machine or the work piece in case a heavy nail strikes a strong obstruction or some impenetrable element is laid in the path of the driver.
I claim as my invention:
1. In a nailing machine, the combination with a support and a nail chuck independently mounted and having a reciprocatory movement thereon, of a driver extending through the chuck and adapted to operate the latter against the work, a nailing head having a cycle of movement through a fixed path, and a spring interposed between the head and driver and through which the latter is operated.
