vTICKER STICK.y

To all whom it may concern Be it known that I, JAMES B. TATEM, a citizen of the United States, and a resident of Putnam, county of Vindhain, State of Connecticut, have invented certain new and useful Improvements in Picker Sticks, of which the following is a specification.

It has been the common practice to employ a picker stick constructed entirely of wood and, while this construction is of advantage in that it provides for a certain amount of desired resiliency and is a protection against serious damage to the loom in that the picker stick, being of wood, may break in thefevent that certain things should go wrong, thus avoiding more serious injury to other parts, all-wooden picker sticks are objectionable in that they crack and break under the normal strains to which they are subjected and, when they become bro-ken orunserviceable, it is necessary to replace the entire stick, although it may be broken or cracked at but one end. y l

The aim of the present invention is toprovide an improved construction of picker stick having a metallic section and a wooden section, the arrangement being such that, in the event the wooden section should break or become unserviceable, it may be readily detached from the metal section and a new wooden section substituted in its place.

The wooden section of my improved stick is relatively shorter than an all-wooden stick and may, therefore, be replaced atf a lesser cost than would be the case if the stick were made entirely of wood, and thus a material saving is had. y y

An object of the invention is to provide a picker stick of the character described having various features of novelty and advantage and which is particularly characterized by its simplicity Vin construction, its economy in manufacture, its effectiveness in oper ation, and the ease and facility with which the sections may be dissembled and assembled. 1

A. further aim of the invention is to provide means for taking up play .between the wooden and metal sections as, for example, where the wooden section shrinks in size.

Other objects will be in part obvious and -in part pointed out more in detail hereinafter.

The invention accordingly consists inthe gagement, as shown in Fig. i1.

features'of construction, combination of elements and arrangement of parts which will be exemplified in the constructionhereinafter set forth, and the scope of the application of which will be indicated in the appended claims.

,Fig. 3. is a transverse section taken on line 3-3 of Figel;

Fig. 4 is a section taken on line 4 4 of Fig. 1'; 1 y f l Fig. is -a view showing the lower end of BRIDGEPORT, CONNECTICUT, A Con-v the blank of metal from which the metal section of the stick. is formed; and

Fig. 6 is a viewv showing, on a reduced scale, another embodiment.

Referring vto the drawing inl detail, 10

designates the metal section, and 11, the

wooden section. In-'the present illustrative disclosure, the metal section is shown as being channel shape in cross section, but it is to be understood that, while this is the preferred form so far as certain features of the invention lare concerned, the metal section may have a shape other than that illustrated. Preferably, the metal section is formed from sheet metal by cutting out a blank to the desired configuration, and then bending or pressing. it to final shape. In the present instance, the lower end of the blank, as will rbe seenk most clearly from Fig. 5, has one corner rounded and its other corner cut away, as at 12, and then the blank'is bent along the dotted lines of Fig. 5 so as to form the flanges, the outer flange being curved at its klower end, as at 13, and the edgesof the notchor cut away portion lbeing in fen- 14, shown in dotted lines Fig. 1, and to which strap a spring is adapted to be connected, engages against the `rounded portion 13.

For the purpose of The strap maintaining the flanges e of the metal section in proper relation and to furnish a substantial bearing for the stud or bolt on which the picker stick is mounted or pivoted, there is pro-vided, adjacent the lower end of the metal section, a wooden insert or block 15 having a through opening 16. The flanges of the metal section are provided with openings in alinement with the opening 16 of the block and, preferably, the edges of the openings in the flanges are flanged inwardly so as to form bosses 17 which constitute substantial bearings for the bolt or stud. Since the bolt or stud has a long bearing in both the block and the bosses, there is but little or no wear between the parts, a feature of considerable advantage. From Fig. 1, it will be seen that the sides of the block l5 are cliannelled or grooved, as at 18, so as to accommodate the bosses. The bosses thus center the block and hold it in proper position.

'Ihe lower end of the wooden section of the picker stick lits between the flanges of the metal section and is secured in positioin in suitable manner as, for instance, by means of bolts 20 passing through the flanges and the wooden section. Preferably, there is provided between the metal section and the wooden section a wedge. 21, the purpose of which is to take up play or looseness between the sections as, for instance, when the wooden section shrinks, and this wedge is further of advantage in that it may be employed for adjusting the height of the lug or sweep-stick strap 22. In the present 1nstance, the wedge 2l is interposed between one of the flan-ges of the metal section and the opposed face of the wooden section and is slotted, as at 23, so as to accommodate the bolts 20. That face ofthe wedge which engages the wooden section is provided with teeth 24; which bite into the wood and thus hold the wedge in adjusted position and against vertical creeping. Preferably, the lug strap 22 is connected to the wedge so that the strap Vmay be adjusted by'varying the posit-ion of the wedge, and also to cause the wedge to be normally held and urged into tighter wedging position by the pull on the lug strap. To this end, in Figs. 1,

y 2 and 3, the wedge isv provided with an arm 26 which extends downwardly alongside of the metal section, and the lug strap 22 is connected to the lower end of this arm in any suitable manner, as byl means of a loop or hanger strap 27 In Fig. 6, the lug strap holder is separate from the wedge. VIt has a resilient arm 26 carried by an attaching portion 30 secured on the outside of the metal section by the bolts 20. 'Ihe attaching portion is slotted, as at 31, to permit the holder to be adjusted longitudinally ofthe picker stick when it is desired to change the position of the lug strap.

It Will be seenfrom the foregoing description, taken in connection with the drawings, that my improved picker stick is very simple in construction and may be economi-- cally manufactured. The wooden section is clamped in place in such manner that it may be readily removed. The metallic section may be easily and cheaply formed and is strong' and durable. The wooden section is secured in place in a simple manner, permitting it to be substituted by a new one when the old one has become broken or worn out. In the embodiment Vof Figs. 1, 2 and 3, the position of the lug strap may be changed by loosening the nuts on the. bolts 20, adjusting the wedge, and then turning up the nuts to clamp the wedge in position. It will be noted that the strains exerted on the lug strap tend to urge or pull the wedge downwardly so that play between the metal and wooden sections is automatically taken up. The wedge cannot move upwardly on account of the teeth 24 which, preferably, are in the form of saw teeth. The arm 26 provides the picker stick with a certain amount of resiliency which makes it more effective in operation.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is in*L tended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
