UNITED STATES PATENT OFFICE.
BENJAMIN S. BENSON, OF BALTIMORE, MARYLAND.
IMPROVEMENT IN MACHINES FOR MOLDING PIPES.
Specification forming part of Letters vPatent No. 116,141, dated June 20, 1871.
To all whom it may concern:
Be it known that I, BENJAMIN S. BENsoN same, reference being had to the accompany ing drawing making apart of thisspecification, in whichv Figure lV represents a perspective view of Fig. 2 represents a vertical section through the same.
Similar letters of reference, where they occur in the separate figures, denote like parts of the machine in the drawing.
My invention consists, first, in the combination of asteady-shaft and sliding packer with a revolving ask, for the purpose of steadying the packer while the iiask is being rammed with moldin g-sand. My invention further consists in combining a feed-hopper and revolv ing measurer with `a revolving `flask, so that the sand shall be measured and regulated to quantity required in the iiask. My invention further consists in combining with such parts of the molding-machine as require free movement one upon the oiher, and are liable to be clogged with dust that accompanies molding operations, pipes or tubes for conducting air through to blow out such dust or dirt.
To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawing.
A represents the base of the machine, and B the uprights for sustaining the operative parts of the molding-machine. C is a turntable, supported on or in the base A, and revolved by means of an endless belt, a a, passing around a pulley at b. Upon this turn-table C the ilask I) is placed and secured, so as to turn with said table. The shaft c that carries the packer D is tubular, and is fastened to a cross-head, E, that can move up and down on or against the uprights B, and be guided and relieved of undue friction thereon through friction-rolls d, bearing against the Ways e on the uprights. A rope, cord, or chain, j', is fastened to the cross-head E and passes over a pulley, g, and to its lower end is attached a weight, h, which aids in raising the packer D',
` as the sand is pressed and built up in the flask,
underneath said packer, or its spiral flange i. The steady-shaft F I make tubular, for a purpose to be hereafter described. It is made to freely but snugly t and pass through the packer-shaft c, and is supported above the top of the shaft c, should it pass above it, (which,
however, is not absolutely necessary,) by theV cross-piece Gr of the frame. The lower end of the steady-shaft F has a recess in it, which receives a journal or bearing, j, which is on the turn-table, and which keeps that end of said steady-shaft in true position, and said steadyshaft, in turn, keeps the packer and packershaft in exactly a true position with regard to the iiask, so that the mold is perfectly true, there being no vibration or straining of the packer or its shaft out of true working position. H is a permanent table, through which the upper part of the turn-table C revolves, and friction-rolls 2 2 are interposed between the stationary and the turning tables, to avoid undue friction. To blow out the dust which would accumulate and prevent the free movement of the friction-rolls, an air-tube is introduced, as at lo, through which air may be blown to remove such dust; and, for a similar purpose, an air-tube, l, is inserted in the tubular steadyshaft F, through which air may' be blown, which finds its way through openings, as at 3 3 3, &c., and blows out any dust or dirt that may get into the packer-staff c, and which, if allowed to accumulate, would prevent the free movement of the steady-shaft through the packer-shaft, or vice versa. To the top of the steady-shaft F is attached a rope or chain, m, which passes over a pulley, n, and thence to a drum, o, which is turned by a crank, p, so as to raise up said shaft whennecessary. A rope or chain, q, is also attached to one of the weights IL, which extends to the drum r, by which the packer-shaft and packer may lalso be raised up when necessary to do so. I is a hopper, into which the sand used in packing the iiask is put. In this hopper there is a float or measuring-wheel, J, with buckets s therein, which takes the sand in measured quantities out of the hopper and delivers it into the chute K, whence it runs into the top of the iiask D; and that the measuring-wheel and theflask may rotate with exactness and uniformity of speed, when regulated, the same endless belt or band a a that turns the measuring-Wheel also turns the iiask, and thus they run together or stop together, as the case may be. The packer, with its shaft, is some one hundred pounds heavier than its balances or Weights l1., so that the sand is very firmly packed by the packer in the flask.
Having thus fully described my invention, what I claim, therein as new, and desire to secure by Letters Patent, is-
1. In combination with the revolving ask D, the sliding packer D', packer-shaft c, and the steady-shaft F, as and for the purpose described and represented.
