" twitch niet SAMUEL II. SMITH, or INDIANAPQLIS, INDIANA, ASSIGNOR ro oSeooD, SMITH e oo., or SAME PLAGE.
Letters Patent No. 110,165, dated December 13, 1870.
IMPROVEMENT IN SAND-PAPERING MACHINES The Schedule referred toin these Letters Patent and making part of the same.
To all whom it 'may concern.:
Be it known that I,v SAMUEL F. SMITH, of Indian-A apolis, in the county of Marion and State of Indiana, have invented new and uscfullmprovements in Sand- Belts; or machines for sand-finishing plow-handles, lasts, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of'reference marked thereon making part of this specification.
This invention relates to improvements in machines for sand-polishing plow-handles, shoelasts,-&c., and consists in the arrangement of devices foradjusting one -of the pulleys whereon the sand-belt is placed, as hereinafter described. j f Figure l is a side elevation of the device. Figure 2 is a top or plan view`of the same. vSimilar letters of reference indicate corresponding parts of the several figures.
The driving or principal pulley, A, that operatesk the sand belt is attached to a shaft, B, that is hung iran upright frame, C, or in any other convenient manner.
The secondary pulley D, that carries the other end of the sand-belt, is hung by pivotsrn anadjustable head, E, that is attached by a pivot-bolt to the upper `end of the adjustable standard F, the lower end of which is attached by a hinge-joint, G, to thc oor H, as shown. The belt is strained or tightened over the pulleys A and D by means of the bent lever I and connecting bar J, by which the standard F, carrying the head and made to conform to the rounded face ofthe pulleys A and D.
In resandiug the belt it is liable to shrink unequally,
in which case it would not run true,'and would be liable to run4 oi the pulley. It is also liable to run off the pulleys in the operation of smoothing and finishing, especially when, from the nature of the article operatedA upon, or the inexperience of the Workman, one edge ofthe belt is u sed. In order to compensate for the unequal shrinkage, and to counteract any tendency of the belt to run off the pulleys by pressure upon one edge, the head'E, in which the Secondary pulley D is hung, is made adjustableso'that the axis of the pulley may he-readily adjusted at right angles to the general line of the belt.
Theditculties heretoforeexperienced in smoothing and finishing articles having irregular or rounded surfaces and short curves have been because the surfaces of the sand-wheels in u'se for that purpose were not of a suiiiciently flexible nature to adapt themselves to such surfaces and forms; and the narrow iiat".belts, while possessing the ,requisite flexibility, were objectionable on account of the liability of the edges ofthe belt to cut into and make notches in the surface.
By the use of a wide belt ruiming over roundfaced pulleys, so as to give it smicircular form,`
these objections 'are wholly obviated. In addition thereto a largely-increased working surface is obtained, by which the operation of smoothing and tinishing such articles as plow-handles, lasts, &c., are more expeditiously and effectively performed.
Having thus fully described my invention,
What I claim as new, and desire to secure by Leiters Patent, isl The .lever I and connecting-bar J, in combination with the hinged standard F aud swiveled bearing E and pulley D, as and for the purpose-specified.
SAML. F. SMITH.
