-8 Claims.

l *FIhis :invention is a division/of a pending application Serial No. 594,028 filed .by .me on February 19, 1932,,and relates to magnifyingattachments intended more particularly .for circular or dial -;5 looping machines such as are used'in hosierymills to-close the toeendsflof stockings.

In-operating machines of the kind lreferredito, the loops along the terminal .edges .at opposite sides of l the stocking toes aresuperposed .and impaled by handupon the radially-projecting.points of the looper dialas said points move past-the operative, the superposed loops-beingafterwards united as they advance through the sewing mechanism of the "machine. This running-on operation is not only very exacting, but tediousbyreason of the fineness. and closeness of the fabric loops.

The aim of my invention is to facilitate the work of the operators of looping machines, and at the same time relieve eye strain, through provision of a magnifying attachment which is simple and inexpensive in construction; which is easily applied to the machines; which permits universal adjustment of the glass in the line of vision for clear magnification of the dial points as they pass so that the fabric loops can be run onto the points with the utmost ease and quickness without attendant danger of loop dropping; and which is moreover shiftable to and fro about the axis of the machine to permit allocation of the glass over the points at any position of the dial.

In the drawing, Fig. I is a fragmentary plan view of a circular looping machine fitted with my improved magnifying glass attachment.

Fig. II is a fragmentary side elevation of the organization; and,

Fig. III is a detail view showing how the magnifying glass is secured to the supporting arm provided for it on the looping machine.

With more detailed reference to this drawing, the numeral 5 designates the dial ofthe looping machine; 6, the fixed vertical. stud about which the dial rotates; and 7, the supporting bracket for the stud;

In the illustrated embodiment, my improved magnifying glass attachment comprises a split collar 8 with bolts 9, 10 whereby it is frictionally clamped to the upper end of the stud 6; and a longitudinally extensible arm 11 which is fulcrumed on the bolt 9 of the collar 8 so that it, together with the parts supported thereby, may be swung upward out of the way from the normal illustrated position horizontally over the dial 5. As shown, the arm 11 consists of two relatively adjustable bar sections 11a, 11b, both of which are cit-5 longitudinally slotted, and which are securable after adjustmentbya .pair of screw bolts -12 with Winged clamp nuts :13. .At itsiouterend the arm llcarries a ,vertical b-racket member ,lflwhichis longitudinally slotted for adjustment vertically andalong said arm,.:the adjustment being fixedlby arscrew bolt 15.and wing nut 16. In turnsecured tothebracket member labymeans of BECIGWzbQlt l'landwing nut.18.withcapacityforup and down and angular adjustment, is the magnifying glass 19. Also. associated withthe-arm .11, isanother longitudinallyslotted vertical bracket memberQZO, which, at its lower end, has a 1 roller :21 to on the topisurfaceof the dial .;5 of the-looping machine. A screw bolt 22 :andwing nut .23.=sery.eto adjustably secure the bracket imember .todthe arm.-11. i

The several described adjustments obviously permit very accurate focal positioning of the magnifying glass 19 in the line of the operators vision over the radially-projecting points 24 of the dial 5. Thus, with the arm 11 positioned as shown in Fig. I and held against rotating with the dial 5 by the frictional restraint of the collar 8, the dial points 24 are magnified as they pass in front of the operator thereby greatly facilitating impalement upon them of the fabric loops. Furthermore, the operator may, if necessary, swing the arm 11 in one direction or the other horizontally about the axis of the'looping machineby virtue of the yielding frictional connection of the clamp collar 8 with the stud 6, to bring the magnifying glass 19 over the points 24 at different portions of the dial 5 for detection of any dropped loops before the stockings enter the sewing mechanism of the machine. Also, as hereinbefore stated, the arm 11 and its appendages may, when required, be swung up out of the Way about the fulcrum 9.

From the foregoing it will be apparent that I have provided a simple and inexpensive magni- A fying attachment which will greatly relieve eye strain and thereby render the operation of looping easier with corresponding gain in the output of the looping machines.

Having thus described my invention, I claim:

1. A magnifying glass attachment for looping machines, including a dial, comprising an extensible arm horizontally overreaching and in part sustained by the looper dial, and means 19 supporting the magnifying glass from said arm with provision for universal adjustment in the line of the operators Vision over the dial points.

2. A magnifying glass attachment for looping machines, including a rotary dial, comprising a -=1;10

supporting arm overreaching the rotary dial, said arm being fulcrumed at its rear end so that it may be swung up and down and being normally sustainedhorizontally by a roller running on the top of the rotarydial; and means'securing a magnifying glass to the outer end of the arm with provision for universal adjustment in the line of the operators vision over the dial points. 3. A magnifying glass attachment for looping machines, including a rotary-L dial,icomprising a 1ongitudinally-extensible horizontal arm over-' reaching the rotary dial, said arm being fulcrumed at its rear end so as ,tobe swingable up and down and being normally sustained horizontally by a roller running on the top of the rotary dial; and means securing a magnifying glass to the outer end of the arm'with capacity for universal adjustment in the line of the operators vision over the dial points. 1

4. A magnifying glass attachment for loopingmachines, including a rotary dial, comprising a supporting arm horizontally overreaching the rotary dial, said armbeing fulcrumed so that it may beswung up out of the way when required; a bracket member vertically. adjustable relative to the arm and carrying a roller at its lower end torun in contact with the top of the rotary dial; and means securing a magnifying glassto the outer end of the arm with capacity forfuniversal adjustment in the line of the operators vision over the dial points.

5; A magnifying glass attachment for looping machines, including a rotary dial, comprising an arm overreaching and in part sustained by the rotary dial; a bracket member secured to the outer end of the arm,said bracket member being adjustable lengthwise as well as vertically of the arm; and a connection whereby a magnifying glass is secured to the bracket with capacity for angular adjustment in the line of the operators vision over the dial points,

' 6. A magnifying glass att chment for looping machines, including" a rotary dial, comprising an extensible arm overreaching and in part sustained by the rotary dial to support a magnifying glass in the line of the operators vision over the dial points, said arm' being swingable horizontally about the axis of the machine to permit allocation of the glass-over the points at difierent portions of the dial.

' 71A magnifying glass attachment for looping machines, including a rotary dial, comprising an extensible arm overreaching and in part sustained by the rotary'dial to support a magnifying glass in the line of the operators vision over the-dial points, said arm being frictionally fulcrumed on the fixed axis of the dial with capacity for being swung upward out of the way when required and laterally thereabout to permit allocation of the glass over the points at different portions-of said dial.

8. A magnifying glass attachment for looping machines, including a rotary dial, comprising an overreaching arm resting on the rotary dial, and means supporting a magnifying glass in the line of the operators vision over the dial points, said arm being frictionally fulcrumed on the fixed axis of the dial and thus normally held from rotating with the latter, but with capacity for being shifted to and fro for allocation of the glass over the points at difierent portions of the dial.
