Description

'Off the roughness of the hoops.

The two machines may be arranged side by side and be geared together in the manner represented in Fig. 8, in whichlVI and N representthe large cog wheels On the shafts bending hoops and are furnished with a of the propelling wheels.

In the Operation of splitting and shaving hoops for sieves the timber must be first split by hand to the requisite thickness*it is then put into the feeding trough and carried forward to the splitting knife E in the manner before described and divided into two parts, one Of which is carried forward tO the knives and shaved on one side and tapered at one end by the cam 71. Fig. 3 on t-he periphery Of the wheel crowding it out-ward against the j knife the said cam forcing the end of the hoop outward toward the edge Of the knife causing a greater portion Of the hoop tO be taken off, by which the requisite taper is made. It is then reversedin position and put into the trough and carried between the rollers and knives and its Opposite side and end subjected to the same Operation of being shaved and tap-ered. I/Vhile these Operat-ions are going on the other half of the piece of wood may be conducted to the second machine by the conducter i) and subjected to similar Operations. Shingles are shaved and tapered in like manner except that they are t-apered only at one end.

In shaving and jointing pieces Of wood for staves the pin m must be adjusted so as to bring the middle of the piece of wood to the vibrating jointing knife n before the cam 0 is made to Operate on the tail of said jointing knife for giving the bilge. The taper is effected by the cam h and vert-ical knives.

In order to split and shave cane for umbrellas, weavers reeds, and other articlesv suitable knives and rollers may be added if necessary while these in conjunction with the groove on the circumference of the wheel will effect the end proposed. When the article is to be planed on both sides and jointed with parallel straight sides then the knives c and the jointers g g are used. But should the edges require to be tongued and grOOved suitable cutting tools may be added vtouching the periphery Of the wheel.

to the frame to effectthe object intended,

" arranged similar to the cutter g and Q. The small roller is brought nearer tO the edge of the knife when a thin shaving is to be taken off, and is effected by having the axle Of the roller' to run in a swivel d Fig. 2. Said swivel having two adjusting screws. The forked arm F may be substituted for the Y swivel d.

The rollers p and r are generally used for small plate to guide the' hoop between them. Should the hoop require tO- form an Oval a .roller of corresponding shape will be required-and the pin m must be placed to correspond with the position Of said Oval t roller. The boxes Of the upper ends Of the `arles are provided with spiral springs to keep them against the wheel and to allow them to recede therefrom when required. The front rollers are provided with sliding boxes and screws t-O prevent them from The other rollers may also be provided with screws for the same purpose.

The knives may be of any size and shape required. rlhe frame may be round Or square and when round made a little greater than the roller turning thereon. And thereV may be several of them arranged one above the Other-the base Or foundation Of the whole structure being square, Or Of any convenient shape. jointer is provided with a spring to return it to its former position after being raised by the cam. The splitting knife is provided with a screw to regulate its distance from the wheel. The feeding trough J is taken away when the article is intended to be shaved of equal width and thickness. The timber should be split by hand small enough for the machine and then passed through the machine a sufficient number of times to bring it the thickness desired.

What I claim as my invention and which I desire to secure by Letters Patent is- The combination of the revolving wheel and cams with the rollers and knives for splitting and dressing pieces of wood as before described.
