ALBERT E. CONVEBS, OF CLEVELAND, OHIO.
HEADER FOR NAIL-MACHINES.
To all whom t may concern.'
Be it known that I, ALBERT E. CONvnRs, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvementl in Headers-for Nail-Machines, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.
While the present invention relates, as just indicated, to nail machines and the like, the characteristic features thereof are equally susceptible of use in connection with anyv type of heading or upsetting machine, whether the article being manufactured is a nail, spike, bolt, or what not.
Such invention concerns more particularly the construction and mode of operation of the heading mechanism of machines of this general class, one object being to provide an actuating mechanism for the header, whatever the form or size of the latter, that will accomplish the desired upsetting operation with a minimum amountof movement. I-Ieretofore such header has generally been actuated through the agency of a crank shaft and hence, irrespective ofv the amount of movement actually required, a certain throw at least as great as the maximum movement and generally greater has been provided.
A further object is the provision of mechanism, that while strong and effective in operation, will nevertheless be extremely simple and little likely to get out of order under continuous use, such as is desirable, if any high degree of economy is to be attained in the operation of machines of this class. It will be understood, of course, that by cutting out all unnecessary movement of the header, the speed of the machine may be very considerably increased, since the mechanism already in use for feeding and gripping the stock may be speeded up far beyond the capacity of any prevailing type of heading mechanism.
To the accomplishment of the foregoing and related ends, said invention, then, c011- Speccation of Letters Patent.
Application led March 23, 1911.
Patented July 23, 1912.
serial No. 616,346.
sists of the means hereinafter fully described and particularly pointed out in the claims.
The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.
In said annexed drawings Figure l is a broken plan view of a nail machine showing the present improved header mechanism; Fig. 2 is partially a side elevation and partially a vertical section of such a machine on the line 2 2, Fig. l; Fig. 3 is a transverse section on the line 3 3, Fig. 2; Fig. 4 is a transverse sect-ion on the line 4 4, Fig. 2; i
Fig. 5 is a diagrammatic representation, four times enlarged, of the actual path of header travel in a machine adapted for heading eight-penny nails and Fig. 6 is a section on the line 6 6 in Fig. 4.
Only so much of the general frame work or bed 1 of the machine, as is essential to a showing of the mechanism now to be described, is involved'in the several figures of the foregoing drawings; and similarly the accessory parts of the machine, including the driving mechanism and the stock feeding and gripping mechanism have been largely omitted from such illustration, as forming no part of the present invention. The stock likewise not shown, but consisting of a wire rod, or bar as the case may be, is designed to be intermittently fed forwardly on the line w Fig. 2, being securely gripped at the end of each advance movement with a sufficient portion projecting beyond the line g/ Q which marks the inner face of the gripping dies 2, to provide the material for the head. The header or die 3, whereby 'such head is formed, is carried by a supporting member or carrier 4, that constitutes part of the present combination. First noting said tool, however, it may be remarked that it is interchangeably mounted on said supporting member and may take on any desired form so as to correspondingly upset and shape the head out of such projecting portion of the stock. The member e, which is thus seen to carry the heading tool, is itself carried by a second member 5, being pivotally attached thereto by a pin 6, so as to oscillate :freely in a vertical plane. Said second member is in turn pivotally mounted on the machine trame 1 about an axis 7 parallel with said pin, so as to also have an oscillatory movement in a vertical plane. rllhe movement ot the :forward end ot the header supporting member, and thus ot the header itself, will accordingly be compounded ot the oscillatory movement ot said member and that ot the second member 5 whereby it is in turn carried. Movement ot' said second member and ot said tirst member, so tar as movement of the latter is independent ot that oit the second, is derived from drive shaft 8 that is driven in any suitable fashion, as need not beexplained. rl`his shaft, it should be explained, has been omitted from the showing in lilig. 1, in order not to conceal certain details located beneath the same. The rear ends ot said members d and 5 are respectively extended below and above said shaft and carry rollers t), that are adapted to bear against corresponding cams 10 mounted on said shatt. ln order that operative strains may be properly distributed, the irst member l is biturcated at its rear end, but it. is not necessarily so, the respective arms 11, lying on either side ot the second member 5, as clearly shown in Fig. 1.
The itorm and angular location of the cams 10 on the shaft 8 which bear againstl the rollers 9 carried by the rear ends of the two members l and 5 will obviously vary, depending` upon the amount and character oit movement which it is desired to impart to the heading tool; accordingly in Fig. 2, merely the throw ot said cams is indicated by the dotted circles the irst, or header-carrying, member being represented in this same. ligure, as in its central position of travel.
The rear ends et the two members 4e and or rather the rollers 9, which are carried by said ends, are maintained in close Contact with their corresponding cams 10 on the shaft 8 by means ot suitable springs 12 and 13 illustrated in F ig. f2 as leatl springs, the iirst of which is recurved upwardly and forwardly and has its forward end connected by a link 14.- with a stay 15 that connects the two arms et the bifurcated rear end ot the first member; the second ot which is recurved downwardly and forwardly and is similarly connectedby means ot a link 16 with a hook 17 on the under side of the rear end ot' the second member. rlhe form and disposition ot these springs, however, is obviously merely a matter oit' design. rlhe torward end of the member 4: which carries the heading tool, is moreover supported, or rather guided, in a grooved guide-roller 18,
shown in detail in Fig. 3, the under side of said member being provided with a projection or rib 19 conforming with the groove 20 in said roller. lt has already been eX- plained that the movement ot' such forward end oi the first member, and of the heading tool carried thereby, is a compound one, and tor the purpose of illustration, a typical movement has been selected and plotted in Fig. The graph which constitutes suoli ligure represents the center line of header travel enlarged :tour times from the dimensions ot such travel in the case of a machine designed for heading eight-penny nails. rllhe forward movement, which performs the actual upsetting operation, is along the base line in the figure from point a to point 5,' thereupon the header is retracted to the point c, just tar enough to clear the head termed on the stock; then said header is raised and at the same time further retracted along the line c-(Z, being iinally moved along the line Z-c to a point directly over its initial, or starting, position. Thereupon it is dropped along the line c-c to such starting position. Then the magnification of the movement represented in Fig. 5, as just described, is taken into consideration, it will be appreciated how very slight such movements are. Not only is it possible, on this account, to perform the complete cycle of movements much more rapidly than heretofore, but, the full torce of the advance being concentrated into a short movement, as much power as may be required for any upsetting operation is always available. Owing to this same reduction in the length oit themovements ot' the several parts, the wear on the bearings is minimized and triction losses correspondingly reduced, and I have accordingly found a very marked economy is obtainable in actual use of machines constructed in accordance with the foregoing speciiic-ations.
An additional advantage gained by the present invention may finally be noted. In the prevailing type ot' nail machines, it is necessary to have mechanism for ejecting the nail as termed. In the present machine, however, the stock is fed forward below the header 3 when it is in its upper retracting position, and as the header descends, as may be seen in Fig. 5, it gently knocks the formed nail down into a receptacle which may be provided to receive the nails. The necessity for the usual clearer ll or kicker with its well recognized disadvantages is therefore entirely obviated.
@ther modes of applying the principle ot my invention may be employed instead ot the one explained, change being made as regards the mechanism herein disclosed provided the means stated by any ot the tollowing claims or the equivalent ot such stated means be employed.
in)y
I therefore particularly point out and distinctly claim as my invention.
