NITED STATES l PATENT FFIC SPINNING-LATHE FOR HOLLOW METALLIC OBJECTS.
SPECIFICATION forming part of Letters Patent No. 596,675, dated January 4, 1898.
Application filed April 23, 1897.
To all whom, it may concern:
Be it known that I, CARL COLLIN, a subject of the Grand Duke of Hesse, and a resident of Offenbach*on-the-Main, in the Grand Duchy of Hesse, German Empire, have invented certain new and useful Improvements in Spinhing-Lathes for Hollow Metallic Objects, of which the following is an exact specification.
This invention'refers to lathes of the kind in whichhollow metallic objects of circular section may be shaped by spinning them and exposing them at the same time to a radial pressure. My improvements in lathes of said kind consist in some arrangements and combinations of parts, as are fully described hereinafter; and the purpose of my improvements is to effect the shaping of the respective metallic object on an automatic way, or letting the respective too] be actuated automatically, parallel to the longitudinal axis or axis of rotation of the object, as well as rectangularly or radially thereto.
The shaping-tool is secured to a slide, and the guide-piece of the latter is also attached to a slide. This slide is moved to and fro along the frame of the lathe, whereas the firstmentioned slide is moved in the direction of .and pressed against the object to be shaped.
Means are provided for letting the tool advance for a short way every time the second slide or main slide changes its direction.
In order to make my invention more clear, I refer to the accompanying drawings, in which similar letters denote similar parts throughout the different views, and in which- Figure 1 is a front View of my automatic spinning-lathe. Fig. 2 is a side View, and Fig. 3 a plan, of the same. Fig. 4 is a front view of the main slide, together with the lower part of the support for the tool-carrying slide and the adjacent part of the frame of the lathe, these parts being drawn on a larger scale. Fig. 5 is aside View of the shaping-tool, (shap ing-roll,) together with its holder andthe respective slide, the latter being in section and these parts being drawn on a still larger scale. Fig. 6 is a plan of the parts shown in Fig. 5, and Fig. 7 is a rear View of these parts.- Fig. 8 is an enlarged side view of the means for operating the tool-carrying slide, and Fig. 9 is a plan of these means.
In the form of construction shown the shap- Se'rial No. 633,508. (No model.)
ing-tool is formed by a roll 1', Figs. 5 and 6, which is arranged in the forked end of the slide h 72.. The latter consists of a bolt h and a'shell h. The bolt may be displaced within the shell and fixed in position by means of a screw h The length of the tool-carrying slide 71 It may thus be adjusted as requisite.
The tool-carrying slide, or, more precisely, the shell h of the same, is located within a guide-piece or hearing to, Figs. 1, 2, and 8, supported from the main slide q, Figs. 2, 3, and 4, by the standard g. To prevent rotation of the circular shell h of the tool-carrying slide Within the bearing a, the latter is provided with a head-screw y, that takes into a longitudinal groove 72, Figs. 5 and 6, of said shell.
The main slide q is supported and guided by the girders 7t, Figs. 1 to 4, of the frame of the lathe and is reciprocated from a disk (1 by aid of a connecting-rod e e. The latter consists of the two parts e and e, that are connected by screws e and may be adjusted in' length according to the distance of the place where the slide q is to pass to and fro or where the shaping-tool is to act, respectively. To regulate the length'of waywhich the slide q is to pass through, the disk cl is provided with a radial slot at, Fig. 1, and the respective end of the connecting-rod e is attached to a slide at, Fig. 3, located within said slot. The slide 46 may of course be fixed in the position chosen.
The disk (1 is secured to a shaft b held by brackets 19 A worm-wheel I), also secured to the shaft b meshes with a worm b, Fig. l, fixed to a shaft If. This shaft has pulleys Z, by aid of which motion is imparted to the lathe. If thus the shaft b is rotated, the worm 12 rotates the worm-wheel b and the disk (I, and the latter reciprocates the main slide q (with the standard q, the bearing a, and the tool-carrying slide 7?. h) by means of the connectingrod e e, the extent of movement of the main slide being regulable by the slot d and the slide at of the disk (1 and the place of work being regulable by the connecting-rod e 6, consisting of two parts, as aforedescribed.
The object to be shaped consists, of course,
of a ring-like or tube-like part, which is putupon or shoved over an internal model or form having the shape which the respective object is intended to receive. Said model or form is held in any known manner between the centers t t of the mandrel t of the fast head-stock a and of the mandrel t of the loose head-stock u and is rotated from the pulleys l by aid of a driver and carrier or by any other of the devices used for such a purpose.
To press the shaping-roll 1" against the piece of work and to cause it to advance according to the progress of the work of shaping, I make use of the device represented in Figs-8 and 9. Said device consists of a double-armed lever m, which is held by a bolt 10, extending downward from a table e. The latter is supported by an arm or a column 7;, which is fixed to the girder 7t of the frame of the lathe. A coiled spring 02', secured at its lower end to any suitable part of said frame and con nected at its upper end with the lower arm of said lever, tends constantly to press this arm against a stop m, secured to the column or standard z. The upper arm of the lever m has a pawl s, which gears with a rack g, guided by suitably-located projections of the table o. The lower end m of the lever m, Fig. 8, projects horizontally beyond the upper end of the stop m and takes into the way of a slotted plate 0, Fig. 4, which is attached to the vertical front side of the main slide q. There are in the form of construction shown two such plates attached to said slide, and I wish it to be understood that instead of using only one lever m and one pawl s and one rack 9 two sets of these parts may be employed. This must be the case if the object to be shaped does not exactly represent a ring, but rather a piece of tube.
The plate 0 aforementioned has a horizon- V tal nose 0, Fig. 4, and between this nose and the upper edge of the plate 0 is an inclined surface 0 which serves for raising the end m of the lever m or for turning this lever, respectively. Every time when the lever is thus turned the pawl 8 takes into the next notch of the rack g, and when thereafter the lever on regains its former position the rack g is displaced for the length of a tooth, this displacement being effected by the spring at mentioned.
To prevent the rack g from going back into its former position on the pawl 3 being withdrawn, said rack is furnished, besides the upper series of teeth, also with a lateral series that cooperates with a pointed bolt 0, Fig. 9. The latter is held by a casing 91. and is exposed to'the pressure of a spring arranged within said casing and allows of the rack g being displaced from the right to the left, but prevents any reverse movement.
In Fig. 9 I have shown the casing n provided with two pointed bolts. The other boltis to come into effect if the lathe is furnished with a second system of parts, such as represented in Fig. 8, the movable parts of said second system being then acted on by the second plate 0 of the main slide q, as aforedescribed.
To transmit the pressure from the rack g to the tool-carrying slide 72. h, there is attached to the table 12, Fig. 9, apattern corresponding to the shape of the model or form held between the centers 75 29. I prefer to construct this pattern of two partsafixed or stationary and a movable one. f is the fixed part, and f g the movable one. The latter consists also of two parts f and g, which may be firmly connected bya screw. The part g serves for transmitting the pressure of the rack g to the part f and" for adjusting the latter according to the position of the rack g, as well as to the extent of displacement of the tool-carrying slide. This may be brought about by slightly unscrewing the connectingscrew of the parts f g and turning this latter part for a smaller or greater angle, when the two parts in question are again firmly connected by the screw.
Having thus fully described the nature of this invention, what I desire to secure by Letters Patent of the United States is 1. In a spinning-lathe for shaping hollow metallic objects, the combination with the shaping-tool, a slide carrying said tool, and being adapted to be displaced in the direction of the object to be shaped, a guide for said slide and a standard for said guide, of another slide carrying said standard, and being adapted to be displaced along the object to be shaped, and means for reciprocating said other slide; a bracket extending upward from the frame of the lathe near to the tool-carrying slide, a table secured to said bracket, a movable pattern attached to said table, a vertical lever attached to the bracket, and adapted to press said pattern against the tool-carrying slide, and means for oscillating said lever by the other slide while this latter moves to and fro, for the purpose as described.
2. In a spinning-lathe for shaping hollow metallic objects, the combination with the shaping-tool, aslide carrying said tool,and being adapted to be displaced in the direction of the object to be shaped, a guide for said slide and a standard for said guide, of another slide carrying said standard, and being adapted to be displaced alongthe object to be shaped, and means for reciprocating said other slide; a bracket extending upward from the frame of the lathe near to the tool-carrying slide, a table secured to said bracket, a movable pattern attached to said table, a toothed bolt also attached to the table, and adapted to press said pattern against the toolcarrying slide, a vertical lever attached to the bracket, and means for oscillating said lever by the other slide while this latter moves to and fro, for the purpose as described.
3. In a spinning-lathe for shaping hollow metallic objects, the combination with the shaping-tool, a slide carrying said tool, and being adapted to be displaced in the direction of the object to be shaped, a guide for said slide and a standard for said guide, of another slide carrying said standard, and being adapted to be displaced along the object to be shaped, and means for reciprocating said other slide; a bracket extending upward from the frame of the lathe near to the tool-carrying slide, a table secured to said bracket, a movable pattern attached to said table, a vertical lever attached to the bracket, and adapted to press said pattern against the tool-carryin g slide, an adjustable projection attached to the other slide, and adapted to oscillateother slide; a bracket extending upward fromthe frame of the lathe near to the tool-carrying slide, a table secured to said bracket, a movable pattern attached to said table, a vertical lever attached to the bracket, and adapted to press said pattern against the tool-carrying slide, and means for oscillating said lever by the other slide While this latter moves to and fro, said pattern consisting of a stationary part, a movable part hinged to said stationary one, another movable part hinged to the first-mentioned movable one,and means for firmly connecting said two movable parts, for the purpose as described.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
CARL COLLIN.
