CHICAGO, ILLINOIS.
SANDING MACHINE.
Application fllcd February 20, 1922. Serial No.,537,861.
To all whom t may concern.'
Be it known that I, ANTON F. Bonoriuns` Va citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sanding Machines, of
which the following is a specification.
The present invention relates to sanding machines.
relates to means for expeditiously sanding the surfaces of wood or other material and contemplates the novel use of an endless sanding belt for this purpose.
An object of the present invention is to provide a sanding machine wherein members to be sanded may be etliciently operated upon.
Afurther object is to provide a sanding machine employing an endless belt in which strips of' material, such as molding and the like, of practically any cross sectional contour may be operated upon.
A further object is to provide a sanding machine which is simple in construction,
relatively cheap to manufacture, and reliable in its operation.'
Further objects will appear as the description proceeds.
Referring to drawings Figure 1 is a side elevation'of one embodiment of 'the present invention;
Figure 2 is an end elevation of the machine illustrated in Figure 1:
Figures 3, 4 and 5 represent in side elevation, bottom plan and end elevation respectively, a modified construction.
Figure Grepresents a detail of construction showing on an enlarged scale part of the structure shown in Figure 3.
According to the present invention, a table is provided having means for feeding along said table the members to be operated upon, said table also having `means for raising ,and lowering same. Novel kmeans are provided, according to the present invention, for operating upon said members while they are being `moved along said table, which means will be described in detail.
Numeral 1 indicates a table which may be elongated as shown in Figures land 2, said table being mounted upon suitablesupports 2 2 in a manner to be lvertically adjustable. For the purpose of providing this vertical adjustabilityof the table l, the table 1 and More particularly the present invention` supports may be provided with side bearings and the weight of said table may be carried by two uprights 2 a, one of which is arranged adjacent to each end of the table. Each of said uprights may be operated by a vertically extending screw 2b, operated by bevel gears 2c 2, which, in turn, may be operated by means of the hand wheel 2d acting through the longitudinally extending rod 2e. Operatively associated with said table 1 are a pair of transverse shafts 3 3 which carry rolls 4 4 for providing feeding motion to members such as strips of molding, parts of furniture, or other members to be sanded. f f
(lo-operating with the supports 2 2 at each end of the machine are a pair of upright supports 5 5 which provide bearings for transversely extending shafts 6 6. Said shafts 6 6 carry a pair of pulleys 7 7 which support the endless sanding` belt 8. which is provided with abrasive material on its outer side.' the details and functions of which belt will be referred to hereinafter. One of the shafts 6 may be provided with a pair of pulleys 9 and 10. of which one may be loose on said shaft 6 and the other may be tight upon said shaft 6. Abelt 11 may be provided for connecting said pulleys 9 and 10 with the pulley 12 of a motor 13. Operative driving connection between said motor and the sanding machine may' be established or disestablished by .moving saidbelt 11 from one to the other of the pulleys 9 and 10. Each of the transverse shafts 3 3 is provided with a pulley 14 having operative connection by means of a belt 15 with a pulley 16 mounted upon the adjacent transverse shaft 6. Adjustable idler pulleys 16 16 may be provided for taking up the slack in belts 15 15 when the table 1 is raised. It will be understood that the details of structure involved in the vertical adjustability of table 1 do not go to the root of the present invention and may be varied within wide limits. According to the drawing, power is communicated to the feed roller 4 by means of the sanding belt 8. It will be understood, however', that, if preferred, power may be communicated to the feeding rollers in any other preferred way.
Mounted in the upright supports 5 5 are a pair of rollers 17 17 which are mounted in vertical slots in said supports 5 5 whereby to permit a vertical movement of said til) titi
headset provided `for keeping thel sanding belt 8 taut under operating conditions, it will be obvious that said belt 8 may readily be relieved to permit the ready changing of the templets 27-27 for operation upon different designs of molding. l't will be noted that no Contact with the sanded side of the belt 8 is necessary except the contact which is desired. between said sanded side and the members to be operated upon.
One embodiment of the presentinvention has been described in detail. Many modifications will occur to those skilled in the it is intended in this patent to cover all such modifications that fall within the scope of the invention. as defined by the appended claims.
