WHITMAN, OF DETROIT, MICHIGAN.
' WORK-FEEDING DEVICE.
Application filed June 3,
To all whomit may concern:
Be it known that I, Jnssr. D. CROSSLEY, a citizen .of the United States of America, residin at Detroit, in the county of Wayne and tate of Michigan, have invented certain new and useful Improvements in Work Feeding Devices, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to a clutch or feeding device that may be advantageously used. for gripping and shiftin stock which extends axiallyof the feeding evice, and as an instance of such use I may mention a single or multiple spindle automatic screw machine in which a gripping device automatically engages a piece of stock and intermittently advances the same, .so that pieces of the stock may be operated upon or used for various urposes. I
In my Patent 0. 1,367,589 granted Feb. 8, 1921, there is disclosed a feeding device consisting of two or more parts and this in vention aims to provide a more simple feeding device which" will be just as positive in its action and may be designed for feeding stock of various cross sectional shapes.
My invention further. aims to provide, as a new article of manufacture, a clutch made of a hollow piece of material having inbent walls providing gripping members adapted to frictionally engage a member placed axially of the clutch to cause a piece ofstock to move with the clutch, unless the piece of, stock is otherwise held. -The co ruotion entering into my inven-' tion will e hereinafter described and then claimed, and reference will noyv be had to the drawing, wherein Figure 1 is a longi tudiifal sectional view of a portion of an automatic machine provided with a clutch 'or feeding device in accordance with this invention, the feeding device being shown in side elevation;
Fig. 2 is an enlarged longitudinal sectional view of the clutch or feeding device;
Fig, 3 is a crpsslsectional view of the same, "and T Figs. 4 and 5 are similar views showing in cross section different pieces of stock that may be fed or manipulated by my clutch or feeding device.
" The clutch or-feeding device is preferabl made froni a single piece of tubular materia and comprises longitndk'ally alining" gitudinal 1921. Serial no. 474,?39.
the fe ding device, unless the stock is other- 7' wise held, when the jaws or members 3 will slide on the piece of stock and eventually obtain a fresh purchase thereon. The intermediate portion has slits or'slots 5 extending longitudinally thereof between the rigid end portions 1 and 2, and the materialbetween the slits 5 is somewhat flat-v tened and bent inwardly, so that the members or jaws 3 will be bowed and present convex faces within the bore of the feeding de vice. It will therefore be possible to spring the members or jaws 3 outwardly and the device may be temporarily, elongated by such action, but the resiliency of the members or jaws is at all times sufiicient to cause a frictional engagement of themembers o1: jaws with the piece of stock 4 to permitv-of the feeding device shifting the piece of stock.
w As shown in Fig. 3 there may be a multiplicity of slits or slots 5, so as to provide an intermediate portion which is su stantially hexagonalin cross sectionv and the plurality of jaws or members are capable of frictionally engaging a cylindrical piece of stock, as shown in Figs. 2 and 3, or of stock, as shown in Fig. 4. In some 1nstances the number and spacing of the 1onof grippin sectional shape of the intermediate portion of the device. This is shown in Fig.5 where the f eding device has opposed members or jaws adapted for gripping a piece of stock a hexagonal piece slots 5 will determine the number 1 members-or jaws and the cross which is rectangular in cross section.
Since the end ing device are-rigid, it is possible to clamp or otherwi e engage either end portion for portions 1 and 2 of the feeda bodily shifting the feeding device, and as an instance of the connection for the feeding device, the rigid end portion 2 has an xteriorly screwthreaded nipple 7 and this inplepermits of the clutch or feedlngdevice eing used in an automatic machine, a por-' tion of which has been shown in Fig. 1 as an instanceof .a commercial use'for the clutch.
or feeding device. I
The machine-includes a bearing 8 foraattaching plate 33 is preferably of single piece construction, as in the form illustrated in Figure 1, and the equalizing devices em ployed in connection with the form shown in Figures 5 and 6 consists of bars 4:1 sup ported by cushioning springs 42 and traversed by wings 43 depending from the table top and having a pivotal or rocking mounting thereon as shown at 44, the intermediate portions of said wings forming runners 45 having a tongue and groove engage ment with the bars 41 so as to compensate for the angular relative movement in any direction of the table top and supporting frame and serve to prevent the swinging or prolonged vibratory movement of the table top due to the movement of the surface by which the frame of the structure is supported.
from the axis thereof and to said legs at a distance above the bases of said legs, and said supports being disposed respectively in planes passing intermediate the terminals of the legs supporting them.
In testimony whereof I affix my signa ture in presence of two witnesses.
