ATTACHMENT FOR WOODWORKlNG-LATH ES.
SPECIFICATION forming part of Letters Patent No. 569,197, dated October 13, 1896. Application filed May 5, 1896. Serial No. 590,281 (No model.)
To ctZZ whom it may concern:
Be it known that I, JOHN G. HALLSTROM, a citizen of the United States, residing at J amestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Wood Turning- Lathe Rests, of which the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to certain new and useful improvements in attachments for woodworking-lathes which are designed for various kinds of work and in which the various knives or cutters may be accurately adjusted and maintained in perfect position during the time the machine is in operation, and the attachment caused to slide longitudinally, by means of handle-pieces on the same, so that the cutter or cutters may-operate upon the stick with uniformity and precision throughout its length.
My invention consists, essentially, of a member secured to the frame of the lathe and I provided with a groove at one side only of the axial line of the work and a combined rest and tool-holder having a member to engage and slide in said groove, whereby the attachment may be manually slid longitudinally along the frame of the lathe and the knife or cutter adjusted with accuracy with relation to the object to be acted upon.
My invention also consists of the parts and the constructions and combinations of parts which I shall hereinafter fully describe and specifically claim.
Referring to the accompanying drawings, in which corresponding letters of reference indicate like parts, Figure 1 represents a perspective view of a lathe attachment and its adjuncts constructed to embody my invention. Fig. 2 is a front elevation of the same. Fig. 3 is a cross-sectional view on the line 00 w of Fig. 2. Figs. 4, 5, and 6 illustrate modifications to be hereinafter referred to.
In the present instance I have omitted to show the frame of the lathe andits usual head-stock, tail-stock, &c., and have simply illustrated my improved attachment as detached from the lathe, it being understood that said attachment is capable of use on most, if not all, of the types of woodworkinglathes now in general use.
To some convenient part of the frame of the lathe and extending longitudinally along the same and being fixedly secured to or an integral part thereof, if desired, is a bar or member A, of metal, having in its under side and extending the whole or the major portion of the bar a groove B, preferably of dovetail form in cross-section, as shown in Figs. 1 and 3. Within this groove, which is located upon one side only of the axial line of the work, is fitted and adapted to move the slide 0, from which arms I) extend and have their outer ends formed with bearings for a shaft or rod 6 5 D, which extends parallel with the slide and essentially in the horizontal plane thereof. Upon this rod the knife-holders E are hung so that they may swing about the same, said holders being of any desired number and form and adapted to securely and adj ustably hold the knives or cutters in any well-known and appropriate manner. In the present instance in Figs. 1 and 2 I have illustrated five of the holders, two of which are provided with knives or cutters; but it will be understood that any number and design of holders and cutters may be carried by the sliding ate tachment herein shown, and each knife or cutter may have its own handle extended upwardly, or there may be a handle-piece F fixedly secured to the attachment or to one of the holders for the purpose of furnishing a convenient means for manually moving the attachment and its adjuncts longitudinally along the machine essentially on the same principle as a feed-screw. operates upon the rests or stocks of both metal and wood work-' ing lathes.
To the rear side of the grooved bar or mem- 9o ber in which the rest and tool-holders are fitted are bolted angle-plates G, and to the lower horizontal members of the same is secured a pattern H of any desired form, said pattern being provided with slots a, in which 5 engage set-screws b, which adj ustably secure the pattern in position.
In Fig. 1 the holder which, carries one of the knives or cutters has secured to its under side a plate 0, to which is adjustably secured red by set-screws a second plate d, with a downturned arm d adapted to run in contact'with' a. the formative edge of the pattern, as shown, '1 whereby the holder to which these plates are secured will be automatically raised and lowered as the downturned arm (Z travels in contact with the elevations and depressions of the pattern. Each of the devices thus far described, except the pattern and the means for securing it, is mounted on and is to be moved with the attachment, the slide whereof operates freely in the groove in the bar or member A, as before described. The angleplates G, which secure the pattern to the grooved bar A, are also formed with slots 6, which are engaged by set-screws or bolts 6, whereby the distance between the bar A and the pattern and the relative positions of these parts may be adjusted as the circumstances require.
In Figs. 4, 5, and 6 an essential portion of my invention is shown in connection with'a knife or cutter for forming a rosette. In these instances the grooved bar A receives the head of the slide 0", the said slide having a rigid knife-holder at or near its outer end and provided with one or more set-screws for adjustably holding the rosette'knife or cutter Iof suitable form and construction. In these figures, aswvell as in Figs. 1, 2, and 3, the slide which carries, the knives or cutters and their adjuncts are maintained'in perfect position and areaccurately guided by the sliding engagement of the slide in the groove of the bar A or A. This attachment'of the slide and the free sliding movement it is permitted to have in the groove of' the bar and manipulation of the cutting appliances and renders the work of the cutters a matter of easeand certainty. By thedevices and arrangements'described I am enabled'to turn a piece of wood anywhere from one-quarter of an inch to two and one-quarter inches in diameter, after the'knives are once adjusted, without stopping the machinery or altering the positions or alinement of the knives, while the iron pattern shown in Figs. 1, 2, and 3, and the engagement therewith of the downturned extension of the adjustable plate d, gives to the knife or cutter with which it is connected such a-precise direction as is difficult to obtain by hand in the usual manner. By simply raising the handle the knife or cutter maybe made to cut into the block of wood as shown in Fig. 2, this being because of its fixed position in the slide and the latters attachment and slidable action in the groove of the bar or member A. This grooved member also serves as an accurate guide for the rod D upon which the knife-holders are pivotally hung, thereby maintaining the knives in proper position for best service, and this same groove in the .bar or member A provides-an easy, safe, inexpensive, and natural guide for the positions of the knives and all the tools used in turning apiece of wood combining the automatic method and the use of the hands.
Having thus described my invention, what I claim as new, and desire to secure'by Letters Patent, is
1. A lathe attachment to be manually operated and comprising a grooved bar at one side only of the axial line of the work, a slide mounted in said groove and having a head extending along the same, a knife-holder ex tending laterally from the slide and a knife in said holder, said slide and holder being so connected that they may be jointly and freely moved along the grooved bar, by hand, so that their relative positions may be maintained.
2. In a latheattachment designed to be operated by hand, the combination, with a fixed grooved bar or member upon one side only of the axial line of the work, of a rest comprising a slide to engage and to be moved, by
