(ol. 1er-162) This invention relates to an improved lap stick adapted for use in a lapper picker, intermediate picker, one process picker, carding machine, and in fact in any machine where va lap roll is formed or used in ñbre preparation. " Y - A lap roll in a lapper picker is usually formed on a hollow lap pin. When the lap is placed in other fibre preparation machinery such as inter I mediate pickers, or carding machines for exam ple, the lap pin is removed but a lap stick re mains in the lap roll for‘facilitating the handling of the lap roll, as in processing the same in sub» sequent machines, the lap stick serves as a stay or a guide for the lap roll and ‘in machines such as intermediate pickers and' carding machine the lap stick ‘engages a suitable guide or standard to prevent bodily movement of the lap roll vas the lap is drawn therefrom. ‘ » Lap sticks heretofore have been >provided for the insertion in the lap pins so that the lap pin can be removed from the lap roll, leaving the lapï stick in position. The- lap sticks in general use heretofore, have been of the type shown in Pat , ent No. 355,508, issued on January 4, 1887. This 25 type of lap stick has a cast'iron handle riveted thereon and this handle Very often would break, necessitating another handle being placed there on. When a lap roll is removed from a picker, for example, the lap, rolls are stood on end with 30 the head of lap pin being disposed downwardly next to the floor or container in which the lap ' roll is placed. Very often it happens that the cast iron head of the lap pin when placed upen the floor with undue force, will crackand in sub 35 sequent operations this cracked cast iron handle would become separated from the lap stick and would cause the lap roll to creep into the process ing machinery and sometimes results in destruc 40 Ation or serious damage to the machine for proc essing the'iibres, such as, for example, the broken lap stick entering the feeder or licker-in of a card or by passing through the fluted feed rolls of the carding machine. I have devised a simple and yet very 'efficient 45 lap stick which remedies all of the above-named defects of the lap stick heretofore in use. I pro vide a one-piece lap stick formed of an iron rod which is bendable and which iron rod has one end thereof bent into a circular portion whose plane is disposed at right angles to the longitudi nal center of the lap stick. This provides an in tegral handle member of the same material as the lap stick, which handle will not break and be come separated from the lap stick, and'there 55 fore, provides a lap stick vhaving a much longer life than thejold type heretofore employed and one which makes it practically impossible for any damage to occur to the machinery due to the breakage ofthe lap stick. It is therefore, an object of this invention to I.. provide a lap stick formed of a bendable iron rod 'Y having one end thereof bent into a circular han dle portion disposed at right angles to the main body of the lap stick. ' Some of the objects of the invention having been stated„other objects will appear as the de scription proceeds when taken in connection with the accompanying drawing in which:-V Figure with the Figure Figure ' 1 is an isometric View of my lap stick lcentral portionthereof broken away; 2 is an end View of the lap stick; 3 is a View of an intermediate picker showing my lap stickin use thereon; - Figure 4 is a top plan view of Figure 3; Figure 5 is a longitudinal sectional View o through a lap roll and lap pin and showing my lap stick in position; ' Figure 6 is a view of the right-hand end of Figure 5 but sho-wing the'position of the lap stick as the lap pin is being Vremoved from the lap roll. Referring more speciiically to the drawing, the numeral l5 indicates the lap stick proper which is bent as at ll, at right angles and after being bent outwardly a suitable distance is then bent laterally and formed into a complete circle form- ¿ ing a handle member l2. The lap stick is usually inserted in a lap pin i3 disposed with a lap Vroll I4. ’I‘heY lap roll is formed on a picker and is laterV employed in intermediate and finisher pickers, such as shown by reference character I5. In one process pickers, of course, the fibres are CO Cl passed from the breaker to a series of pickers to the ñnisher picker where the lap roll is formed, but in other forms of pickers the breaker lapper forms the lap rolls on the lap pin and then they are transferred to the intermediate picker as shown in Figure 3. YThis intermediate picker has an endless chain l5 for feeding the laps` from the lap rolls It. It will be seen in Figures 3 and 4 that the lap sticks l@ rest behind the standards l1 and the lap stick is usually much longer than the lap width and projects laterally from one side andthe handle member l 2 serves as a guide with relation to standard i 'l on one side so that creep ing of the lap stick from the lap roll is avoided. When the lap roll is formed on the picker and is transferred to other machines such as another intermediate or a. finisher picker or into a card ing machine from the finisher picker only the lap stick remains._ The lap pin is removed from 55 2,105,064 2 the lap roll as shown in Figure 6, leaving the lap stick to serve as the guiding means and handling means for the lap roll. It is seen that in any of the above-described machinery that should the handle portion become separated this would allow a creeping away from the observer in Figures 3 and 4 and would allow the lap roll along with the broken lap stick to be carried forward into the beater 20 of the inter mediate picker in Figures 3 and 4, doing serious damage if not irreparable injury to the beater. The same damage might occur in a carding ma chine as previously explained. It is therefore seen that I have provided an in tegral one-piece lap stick formed of a relatively non-breakable material so that the probability of breakage and resultant damage to the machine is avoided. ' In the drawing and speciñcation there has been set forth a preferred embodiment of the invention and although specific terms are employed, they Cil are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claim. I claim: A lap stick formed from a rod or iron having one end bent laterally at right angles to the rod and then bent into a circular portion occupying a plane at right angles to the longitudinal center ` of the rod. 15, JAMES R.
