' PULLEY GUARD AND HANGER Filed Oct. 23, 192
This invention relates to pulley guards and supports, with special reference to types used in "connection with single grooved sheaves for supporting clothes lines and other small ropes or cords. An object of the present provide a simple but effective device of unusual strength, due to its design and absence of joints as in built-up or pieced construction.
A further feature is in the provision of hanger of unitaryconstruction, made in any exceptionally economical manner from a sheet of suitable material, substantially without waste. Another purpose is ,Figure 2 is, a plan vlew of one ofthe blanks as sheared from a sheet of the ma 7 terial.
Figure is a planview df'the blank as flanged and pieced preparatory tobendingQ into the completed shape asshown in Fig ure 1.
y of metal, such for instance, as sheet steel, having the ductility and strength required,-
over all length of duced.
' Theblank comprises a straight central v I element 6, cut diagonallyof the sheet,'of
which it occupies the mid portion, and
formed at the ends of this element are arms Z8, of uniform length which extend at right angles to the bar element 6 and in opposite directions;
' '50 All these elements are of uniform width t V 7 across. invention is to I I which s multaneously produce flanged edges to produce a unitary hanger of pleasing appearance, readily formed andeasily assembled-With a pulley. These objects are attained by the novel 20 design, combination and arrangement of secured, as by spot welding, to the flats 16 In greater detail the drawingsshowin, Figure 2, a fragment of a sheet or strip5 the width of the sheet being equal to the,
the zig-zag blank pro- T 1 pretedas illustrative rather than limitative of the invention, of which embodimentsmay andlength and canbe sheared without pro-o 1 I ducing a kerf or waste of any kind, except small triangles at the endsof the arm's,g I which are finished at right angles squarely These blanks are struck between dies 91() the former extending, at 11,along the adjacent edge of the "arm 7 and the flange 10, is continued at 12 along the adjacent side of thearm 8.
It is to be noted that the outer corners of the bar element 6, at the intersection of the arms 7- 8 are levelled leaving flats 15- 16, which contain central perforations '17- 18', and similar perforations 19-20 are formed in the arms 7+8 near theirends,
If preferred, acentral groove 21 may be produced inthe barelement 6, the same 7 tending to stifien the structure when given itsfinal shape, being then disposed at the V bight of the 'loop' 22 formed by bending the 1 element to produce parallel sides 6-6. x
The arms '78' are similarly bent to produce loops; 7,' and 8-8, bringing the per forations17-20 and 18+19 into register, whereupon the ends of the" arms 78 areand 15 respectively,thus providing a firm and rigid structure of greatstrength and good appearance. V a When the pulley is to bev assembled it is entered between the sides of the framethus produced and a spindlepin'passed through the alined pairs of perforations to act as an arbor 'on which'the pulleymay freely f rotate. 7 190 The foregoing description is to'be interstamped from a single piece of sheet metal 9 to present a central bar member having extensions reaching in opposite directions at right angles from its ends, said bar being bent to produce an open 100 extending up- Wardly and said extensions eing looped to encompass the sides of the pulley, the free ends of said side lo ps being overlapped and ecured to the jun i n of the connected ends, and means to receive a pulley pivot through the double thickness of the end loops.
In testimony whereof I aifix my signature.
