` IMPROVEMENT IN PLANmG-mAcHiNEs.

Specication forming part of Letters Patent No. 174,944, dated March 21, 1876; application filed April 20, 1875.

To allWwi-llmg/ concern Be it knownl that I, ADAM CANT, of the town of Galt, in the county of Waterloo, in the Province of Ontario, Canada,manufactur er, have invented new and useful Improvements in Planing-Wlachines, of which the following is a specification:

My improvement relates more particularly to improvements in that class of wood-planin g machines commonly known as rotary bedplaners and it consists, first, in the novel construction of the bed-slats and the peculiar manner in which they are coupled together to form a continuous bed, by means of male and female lugs cast on'the ends of alternate slats it consists, secondly, inthe combination of the driving-wheelswith the slats, the said wheels having peculiarly shaped and placedltteeth, which gear with projecting shoulders cast on each end of the slats.

The principal object of my invention is to form a strong, durable, flexible, and cheap connection between the bed-slats, without the use of detachable coupling-pins or bolts, and at the same time reduce the amount of lost motion caused by friction.

In the accompanying drawings, Figure 1 is alongtudinal section of the inner frame and attachments ofarotary bed-planer constructed according to my invention. Fig'. 2 is a crosssection of the same. Fig. 3 is a bottom plan of a pair of slats on an enlarged scale. Fig. 4 is a cross-section o f the same.

A is the inner frame, which is attached tol an outer fraure in the usual way,-and which is raised and lowered by the usual screw and nut mechanism.

To each end of A the usual wing-pieces A1, with end rollers, are attached at a a. The sides of the frame are connected together by two solid web-braces, a', and are constructed with inwardly-projecting flange pieces A2 at the top'. These pieces form the bearing upon which the slats travel, and at each end they are'curved downwardly, so that their upper face dips to the circle formed by the slats when on the en d rollers.

B is the revolving bed, composed of the slats C and C1, which are coupled together by the male and female lugs C3 and Gr cast on alternate slats, as shown in Figs. 3 and 4. The lugs C3 and G are double-ended, the former or male having two projecting cylinders, C2, which fit into recesses c' cast in the enlarged ends G1 of the female lugsG. The shape of the recess c is such that when the slats are coupled `together they cannot be uncoupled without placing them in a position they can never assume in the working of the planer.

F are the bed-driving Wheels, fitted to the shaft F', which is driven by the toothed wheels D and D in the usual way. On the periphery of the wheels F lugs or teeth f are cast, which t between the slats, one side bearing against a projection, H, cast on the outside of the lugs C3 and G; thus the rotary motion of the wheels is communicated to the slats, causing them to travel as desired.

Ourthe inner edge of the driving-wheels a shoulder, f', is formed, against which the slats bear when reversing at each end, downwardvly-projecting pieces G2, being cast on the bottom face ofthe slats G1, which and the under side of the male lugs C3 tit the circle 'of the beibre-mentioned shoulder f on the wheels F.

The shaft E of the wheels E3 revolves in adjustable flanged boxes El, which are titted in a slot cut in the frame A. The position of these boxes is changed by the adjustingescrew E2, one end of which is threaded and entersa similarly-threaded hole in the side of the box, the other end bearing against the frame A thus, by turning the screws E2, the tension of the bed may be increased or lessened, as desired.

c and g are braces cast on the under face of the slats for strength. The bed-slats, when traveling on the han ges A2, are level, the faces of the'ends beyond the edge of the lugs coming together, the remainder of the slat being less in width, leaving an open parallel space between each.

The advantages gained by my invention are, that the slats are strongly and cheaply con- /nected together, with great iieXibility, without the use of pins or bolts, which, experience has proven, wear rapidly in`use; that the tension of the bed can be adjusted when requiring adjustmeut; that the whole mechanism is strong and durable. and any part can readily be replaced when broken or worn out.

I claim as my invention- 1. The endless rotary bed B, consisting of the alternately-arranged slats C, with doubleeuded male lugs cast thereon, and slats G1, with double-ended female lugs cast thereon, arranged and operating substantially as described, and for the purpose specified.

2. The driving-wheels F, with teeth f and i @he-limer f, i ebmbimcidnfwinh the projections H and G2 and lugs C, arranged and operating substantially as described, and for the purpose specified.
