Description
Patented Nov. 5, 1940 UNITED STATES PATENT OFFICEv -HANDABRADING TooL TheodorezNordlund, Jamestown, N, Y1.; 1 Applicationjune1o,1939,-seria1N0.'27s,532 1' Y efclaims. (0151-181) 'I v This invention relates to an improvement in abrasive tools and particularly to a holder for abrasives in sheet form.
j One form of the present invention is directed to the provision of a holder for sheet abrasives of the nature of a hand tool and includes a grip or handle element and a shoe. A sheet of abrasive is placed against one surface of the shoe and the ends securely clampe'dfbetween the yshoe 'and the handle element. j
The invention has for its objects and advantages the'provision of a holder which is extremely simple and durable in construction, eiiicient in i use, and also one that firmly clamps an abrasive sheet and yet is r-eadily releasable--to remove and replace a worn out sheet. The device is' adap-table for use on surfaces of various contours by simply substituting a shoe of the desired contour.
Other and further objects `and advantages of the invention will bemore` fully understood and appreciated from a consideration of the following specification taken in conjunction with the accompanying drawing; and in which Figure 1 is a side elevation of one modification of the invention, parts being broken away to disclose structural details;
Figure 2 is an end view of the structure shown in Figure l;
Figure 3 is a vertical sectional view, taken substantially on the line 3-3 Aof Figure 1, and shows a shoe of modied contour; and
Figure 4 is a side elevational view, partly in section, of the device about to be assembled.
Reference is had to the drawing wherein the numeral I0 is employed to generally designate a tool for use in polishing or abrading surfaces by hand. The tool comprises a body or handle element II and shoe I2. Suitable recesses I3 are made in the body I I -to provide a convenient hand grip. The under face I4 of the body II is provided With a pair of rods I6, located adjacent the side edges. These rods may be partially embedded in the under face I4, as shown in the drawing, and terminate in hook-like ends I'I. The ends I1 are embedded in the ends of the body portion II and serve to secure the rods against displacement.
Referring particularly to Figures 3 and 4 of the drawing, it will be noted that a vertical opening or slot I8 is made centrally of the body portion II. This opening extends to adjacent the top of the body portion, and the walls thereof may be fitted with a liner I9. 'Ihe liner is closed at the upper end of the slot as by a fold 2| and terminates in anges 22 at its lower end. The flanges 22 fit into suitablev recesses in the under face I4 of the body portion and are secured to said body portion in any `suitable manner, as by screws 23. A further slot 24 is made in the body portion II. This slot -extends longitudinally of the body portion and intercepts the upper end'of the vertical slot I8. Thebottom wall of the slot 24 is dened by a plate 26 thatis suitably slotted to receive the liner I9.
The shoe I2 may be the same length and width as the body portion I I and have an under surface of any desiredcontour. i For example, if it is desired rto use the device in abrading or polishing flat surfaces, the shoe shown in Figures l and 2 would be appropriate. However, it is possible to nish molding surfaces by simply substituting the shbe I2-a, shown in Figure 3 of the drawing, for the flat surface shoe described. Regardless of the contour of the under surface of the shoe the upper surface 2'I thereof is flat and provided with longitudinally extending marginal grooves 28 that are adapted to receive the rods I6 of the body portion I I. Centrally of the upper surface of the shoe is an upstanding U-shaped strap 29, the ends of which terminate in flanges 3I that are secured by screws 32 to the shoe. The strap 29 is adapted to project upwardly of the slot I8 between the walls of the liner I9 and into the slot 24. A tapered locking bar 33 is projected into the slot 24 through the looped end of strap 29 and serves to secure the shoe against displacement from the body portion II.
In operation a sheet of abrasive of suitable size is placed against the under face of the shoe I2, being wrapped around to position the ends on the upper surface 2'I overlying the grooves 28. With the sheet in this position, the strap 29 of the shoe i-s projected into the slot i8. The bar 33 is then moved into the slot 24 and, since this bar is tapered, continuous inward movement thereof causes it to engage the looped portion of the strap 29 land the plate 26, drawing the block and the edges of the abrasive sheet into pressure engagement with the under surface I4 of the body portion II. As may be seen from the drawing, the sheet is forced into the grooves 28 by contact with rods I6 and thus provided full length securement. When the abrasive surface of the sheet has become worn or it is desired tosubstitute a shoe of diierent contour, the small end of the bar 33 may be tapped slightly to loosen it and said |bar may then be readily withdrawn and the body portion and shoe disengaged.
It is apparent that the above described invention is susceptible of many uses with some struc- CFI tural variations vand such variations are contemplated insofar as they are Within the spirit and scope of the invention as defined in the hereunto annexed claims.
Having thus set forth my invention what I claim as new and for which I desire protection by Letters Patent is:
1. A holder for an abrasive sheet Comprising a pair of members, the adjacent faces of said members being flat, said sheet enclosing one of said members .and having its ends overlying the fiat face thereof, means operable to resist relative lateral displacement of said members when in superposed relationship, and clamp means operable to draw said members into pressure abutment with the ends of said sheet whereby said ends Will conform to the contour of said intertting means and be secured against displacement.
2. A holder for an abrasive sheet comprising a pair of members, the adjacent faces of said members being flat, said sheet enclosing one of said members and having its ends overlying the flat face thereof, rods onthe iiat face of one of said members, the otherof said members having grooves for receiving said rod-s when said members are in superposed relationship, and means operable to draw said members into pressure abutment and fcause the ends of said sheet to fit the contour of said grooves.
3. A holder for an labrasive sheet comprising a pair of members, one of said members being enclosed by said sheet, a U.shaped strap on one of said members adapted to project into an opening in the other of said members when said members are superposed, and means engagveable with the closed end of said strap, said means being adjustable to draw said members into pressure abutment with the ends of said sheet whereby to secure said sheet against displacement.
4. A holder for an abrasive sheet comprising a body element and shoe, adjacent faces of said element Iand shoe being flat, said sheet being adapted to enclose said shoe with the ends thereof overlying the flat face, a U-shaped strap projecting upwardly of the flat face of said shoe, said body element having an opening to receive said strap, a wedge shaped member projectable through a further opening in said body element into engagement with the closed end of said strap, and intertting means on said adjacent faces, the ends of said sheet, when said body element is joined to said shoe, fitting said means whereby to prevent displacement during use.
5. A holder for an abrasive sheet comprising a body element and shoe, adjacent faces of said element and shoe being flat, said sheet being adapted to enclose said shoe with the ends thereof overlying the flat face, a U-shaped strap projecting upwardly of the flat face of said shoe, said body element having an opening to receive said strap, a wedge shaped member projectable through a further opening insaid body element into engagement with the closed end of said strap, rods projecting beyond the face of said element, the tace of said shoe having grooves for receiving said rods and the ends of said sheet when said holder is assembled whereby to prevent displacement of said sheet during use.
6. A holder for an abrasive sheet comprising a pair of members, the adjacent faces of said member-s being substantially flat, said sheet enclosing one` of said members and having its ends over, lying the kfiat face thereof, upstanding means on one of said members projecting into an aperture in the other of said members, and wedge means f in said other member engageable with said means to draw said members into pressure abutment with the ends of said sheet whereby to secure said sheet against displacement.
