EMILE J'. BEIN, 0F NEWARK, NEW JERSEY.
SURFACINGr-MACHINE.
Speccation of Letters Patent. Patented Jan. 10, 1911.
Application filed February 3, 1910. Serial No. 541,678.
To all whom if may concern:
Be it known that I, EMILE J. BEIN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Surfacing- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.
This invention relates to a surfacing machine and more particularly to one in which an abrasive belt is employed, usually a sandpaper belt.
The machine embodies pulleys on which the belt is adapted to travel, these pulleys being mounted on the end of a beam which is adapted to rock.
The machine is preferably made with a beam on each side of a standard, which standard supports the beams and also the driving shaft, the driving shaft having a pulley mounted in the center of the standard and the beams having means co-actingV with the standard for holding the beams in adjusted positions.
The machine is adapted for use as a hori` zontal or a vertical machine, or it can be used at any angle intermediate of the ver tical and the horizontal, the beam being` provided with a table on which the work can be held or supported when it is being ground by means of the abrasive belt.
The invention also provides a driving belt which drives the abrasive belt by means of a power belt which runs over the driving pulley and also over one of the pulleys on which the belt runs, engaging the latter and also the abrasive belt, whereby all the ele ments work in unison.
The invention is further designed to provide platens which are removably arranged on the beam so that the machine can either be used as a cushion or with the platen, according to the work to be done.
The invention is illustrated in the accompanying drawing, in which- Figure 1 is a perspective View of the machine, one of the beams being shown arranged vertically and the other arranged horizontally. Fig. 2 is a side view of the machine partly broken away showing one of the beams in its vertical position. Fig. 3 is a cross-section of one of the beams and showing the standard and the driving mechanism in elevation, the duplicate apparatus on the opposite side of the standard being left oif.
The device comprises a standard -or support havin a base l0 and an upright portion l1 which is forked at its top, as at 12, to form the bearings 13 between which is mounted the power pulley 14. The power pulley operates the driving shaft 15 which can extend only from one side of the standard, but preferably extends on both sides, and is provided on both its ends with a surfacing apparatus, and since these are in duplicate, one will be described in particular. A beam 16 is arranged to rock in relation to theV standard, swinging to either `a horizontal or a vertical position and having a curved bar 17 which has a slot 18 through which can be placed a bolt 19 which screws into the standard l1 and can lock thebeam in its adjusted positions, when the beam is ltipped beyond the vertical by a removable socket wrench 2O shown in Fig. 3 in dotted outline. When the beam is moved to a vertical position, or a position between the vertical and horizontal, the bolt 19 is removed and a screw 18a, secured to a bracket 18b on the standard and passing through the slot 18, holds the beam and its accessories steady. On each end of the beam is a bearing 21, these bearings both being adapted to slide on the beam and being in engagement with a screw 22 which fits into a lug 23 and is provided with a hand-wheel 24. By means of the screws 22 the bearings 2l are adjusted toward and from each other. Each bearing is provided with a shaft 25 on which is fastened a belt pulley 26. Over these two pulleys 26 runs an abrasive belt 27 which is used for surfacing article and is kept taut by the adjustment of the pulleys toward and from each other. j
Intermediate of the pulleys 26, and preferably at the pivot on the drive shaft 15, is a driving pulley 28 and a drive belt 29 passes over the pulley 28 and also over one of the pulleys 26, passing between the pulley 26 and the belt 27, thus acting to drive one of the pulleys 26 and insuring the movement of the belt 27. The drive belt 29 also has another function, and that is to act as a cushion when an article to be surfaced or finished is placed against'the abrasive belt. For certain kinds of work this is necessary,
and the drive pulley operating at the same l speed as the abrasive belt causes no undue friction between the belt and its backing, and at the same time permits enough give or resiliency to the belt to suit certain kinds At each end of the bar 31 is an offset portion 34 against which is adapted to rest a slide 35, this slide being provided with a slot 36 which slides on a screw 37, which screw passes into the bar 3l and holds the slide in its adjusted positions. On the end of the slide is ay bearing 38 into which fits a bolt 3S) which in turn is provided with a nut 40, in the shape of a hand wheel, which acts to tighten up the bolt 39, when necessary, which forces one of the brackets 4:1 of the tableagainst the bearing 38 and thus holds the table 42 at any position it is adjusted to.
This machine is adapted for a great many uses and, having the. platen and also the cushion'backingsfor the abrasive belt, permits of aV great variety of work when it is Y tilted partly, for instance when at an angle over the of about forty-five degrees the under side of each of the pulleys, or the belt passing pulley, can be used as a bufiing wheel; The table 4:2 can be arranged at an angle to the abrasive belt so that when the beam and the pulleys, with theY abrasive belt, are arranged' at an angle out of the vert-ical, the table can be made to set horizontal so that in any angular grinding the work can be fed level or horizontal and the belt is inclined.
Having thus described my invention, what I claim is l', A surfacing machine comprising a standard, a beam on the standard, pulleys arranged on ,the ends of the beam, a pivotal connection for the beam and the standard arranged between the pulleys, an abrasive belt passing over the pulleys, a drive pulley between the first mentioned pulleys, means for adjusting the first mentioned pulleys toward and from each other and a power belt passingv over the driving lpulley and over one of the belt pulleys and passing between the abrasive belt and the last mentioned Y pulley and also being'adapted to act as a e of the'beani,beltpiilleys arranged to rotatev on the ends. of the beam, means for adjustcushion for the abrasive belt.
