MfPLlCATION FILED NOV. 2, 1916- Lgfiwe Patented 0017. 23,191?
I To all whom it may concern:
UNITED sTArEs PATENT orrron.
naenx H; surname :ernenrrnnn, wesnmsroixtn SACK-.HOLDEB.
Be it known that I, FRANK,H.IGILBER'II, acitizen of'the United States, and a resident of Rid'gefieldfCl-arke county,'State of IVashin ton, have invented a certain new and useful Improvementin sack Holders, of V which the following is a specification.
The object of my invention is to "provide a simple and "efficient sack-holding mecha nism especially such as wouldv be suitable for use in connection witha hopper, and. to so contrive such mechanism that t-he weight of the sack will .be utilized to hold and lock the sack-suspending means in their proper In the accompanying drawings:
Figure l is a front elevation of a hopper supported in any convenient way, and illustrates the manner in which my devices operate to hold the sack, and how the weight of the sack tends to securely, hold my device in its sack-holding position;
Fig. 2 is a side elevation of a hopper; and
Figs. 3, a and 5 are details of construction.
The hopper, a, is supported by a supporting bracket 6. At the sides of the hopper are secured bearing brackets c, in the bent ends of which is journaled a shaft (Z. This shaft is provided with sack-holding prongs e, and an arm f, a corner f of the latter being rounded, as shown, and provided with an eye for attaching thereto the link 7, which link supports a chain g. The upper end of the chain is connected to a crank arm h of the shaft 5, this shaft being journaled in brackets 7'. On the shaft 2' is a rigid handle or operating lever is.
As shown in Fig. 2, the crank arms h of l the shaft 2' are set at a slight angle with respect to the operating lever is so as to cause said arms to bear against the sides of the grto throw and hold theicrank arm 72, firmly Patented: Oct. 23, 1917. I imitation li1edNovember2, 191s. Seria1No.129,210. j
against the hopper side;'which effect isob tained by the weight of thesack and itscori-f tents,' -the sack being secured on the prongs'f e. I Aitorsion spring Z on the shaft i norf mally holds the crank arms-h against the side of the hopper. p v t The end of the chain gpasses through a pendent guide lug m, which'is an integralf part .of the bracket 0, and suchlug ismade with a D-shaped eye a, the straight sideof' which is so located as to be at right angles to the pull of" the chain 9, in order to cause the link 9 of said chain to come flataga inst said side, and thus cause the link to'be prop-1 erly positionedto perform itsfunction.
As is to be seen from Fig. 1, when a weighted sack (represented by a) is suspended from the prongs e, the downward pull on' these prongs will cause the end of the'arnr f to exert a tug on the link 9. By'niaking the chain gcfjust such length as shown in Fig. 1, with the crank arms it locked against the hopper, the link 9 cannot be pulled through the eye 71 of the lug m, but will re main in approximately the position shown. The greater part of the upward force exerted by the arm f will be taken up by the link 9 bearing against the upper part of the eye a. By this means very littlev stress is imposed upon the chain 9, thus doing away with the need of a heavy chain. The rounding of the corner f enables the link 9 to accommodate itself to the movement of the chain 9. When the devices assume their sack-holding position, the upwardly inclined side of the eye 72 serves to guide the chain in such way as to re-position the link 9, and thus again produce the locking effect. When the operating lever, is is moved sufliciently away from the hopper, the pull of the sack on the prongs 6 will further rotate the shaft (Z and cause the sack to pull off said prongs. In such rocking of the shaft (Z the chain is readily pulled through the eye a of the lug m.
I claim:
1. In combination with a support, sackholding means comprising a rock shaftprovided with laterally projecting prongs, such shaft provided with an arm; a crank shaft provided with an arm and an operating le- 'ver, a flexible connection between the arm of said pronged shaft and the arm of said crank shaft, a guide for said flexihle con mines or as aint may be banner for nection, and said flexible connection including a link bearing in said guide when the sack-holding means are in their holding position, whereby the tendency of the prong'ed shaft to be rotated by the weight of the sack will "causesaid link of the flexible connection to bind with said guide.
2. In combination with a support, sackholding means, comprising parallel rock shafts provided with laterally projecting prongs, each of such, shafts provided with marn1,a mn1z shaft, provided with arms mesa operating leveigia flexible connection between the arr'nsoii saidpronged shafts and said crank shaft, a guide for said flexible connection, and said flexible connection including a link bearing in said guide when the, saek-liol,cli1ig means are in their holding position, whereby the tendency of the pronged shaft to be rotated bythe weight of the, sack will cause saiddink of the,
flekible connection to bind with said guide.
3, In combination with a. support, sackholdiii-g means comprising parallel rock shafts provided with laterally projecting prongs, each of suchshafts provided with anarni, a crank shaft, provided with arms and an operating lever, a flexible connection between the arms of said pronged shafts and said crank shaft, a guide for sald flexible connection, such guide provided with a U shaped eye the; straight side of which is upwardly inclined, and said flexible connection including a llnk bearing in said eye of the guide when the sack-holding means are in their holding position, whereby the tendency of the pronged shaft to be rotated by the weight of the sack will cause said link of the flexible connection to bind withsaid eye of said guide. a f V 4 In combination with a support, sackholdin ineans coin risin arallel roclc sack holding means are; in their holding position, whereby thetendency of the pronged sh att to be rotated by the weight of the sack will cause said link of thefienible connection to bind with said guide, and the arm of said crank shaft being set oii center and at an angle with respect to theoperatinglever of p the latter so as to bear against the support- 111 advance of said operating lever.
