Be it known that I, RUrUs N. Manual, of Worcestenin the county of Worcester, and State-o Massachusetts, have invented certain new and useful Improvements in' Wood-Moulding Machines; and I do hereby declare that the.`followiu',' ,v'is a full, clear, and `enact description ofthe same,referencc being had to the `accom-V panying drawings, making a portion ot" this specification, in which Figure 1 is a plan view ofl a moulding-machine constructed according to my invention,

'Figure 2 isa vertical longitudinal section of the-same, taken in the linea: xlofiig. 1.

Figure 3 is a vertical transverse section of the same, taken in the line yy of fig. 1.

Similar letters of reference indicate correspondingparts in all the figures 1 The invention consists iuf-oneyor more presser-blocks, having their bearing-surfacesthc reverseof that of' the u1oulding,`and sc arranged in .relation with` the moulding-cutters and-the side-cutter or cutters ofthe apparatus as to hold the stud' and insure its passage in a direct line as it passes from the moulding-cuttersin such position that it may be most advantageously acted-upon bythe side-euttrs einployed to -trim the edge ofv the stuff opposite that atwhich the moulding is formed.

. The invent'ion also consist-s in a novel construction and arrangement of springs with reference'to thesliding bearings of the feed-rollers vof the apparatus, aud'suitable adjusting-screws, whereby the pressure es iertednp'o all the feed-rollers is rendered uniform, and capable of" readyadjustment to any requisite extent, and whereby fthe said rollers may be arranged much closer together thauwhen avstraightr slightly-curved spring is used.

The invention further consists incertain novel means of securing the more eiiicient I 'etention'of the stuit` in proper position as it passes to the moulding-cutters; also, in the construction of the 'presser-blocks arranged over the sur-faced work so as to fit on the surface of the moulding being made, and thereby act 'as a guide to the stuff while the side-cutter is operating thereon, and in supporting the side-cutters in such a manneras toadmit of their adjustment to cut at any desired angle to the flat surfaces of, the stu.

To enable others to understand the construction and operation of my invention, I proceed to describe it with reference to the drawings. i

A represents the bed of the machine, at one end of which are the ,two transverse feed-rollers a, the journals' of which work iu bearings, b, capable of a vertical movement in'guid'es or boxes, c. Provided betweenthe-two i boxes c, at each side of the bed, ,is a bridge-piece, d. The two, bearingsb` at each side of the'bed are pressed .downward by a spring, D, the'ccntral part, a', of which is straight, and has passed through it -a vertical'screw, e, which screws into the bridge-piece d, the two end portions b ofthe springv being' curved'in the form shown more fully in iig.l 1, and resting upon the bearings b to press down' the same, as just mentioned, the pressure being capable of adjustment to any required degree by turning the screw e to raise or lower, us thc case might require, the centre portion a ofthe springB. j I I Situated at the inner sides of the feed-roller bearings just described, are two vertical standards, g, which, nttheir upper ends, are provided with'vertical transverse slots, which receive the ends of a'. transverse bei', 0; which may be adjusted vertically by means of screws, m, which pass down through the caps c of the standards, into or through female screws formed iu the ends just mentioned of the barC. This bur has formed in it' a longitudinal slot, d', into which is tted the upper Vend of 'a sleeve, n, which 'may be xed atanypart of the bar C by means of a locking-screw, e', screwed into the up er end of the sleeve at'thc upper side of the bar, und operating in conjunction with, shoulders a/ formed'upon the sleeve-below the bar. y

Shown at r is a stem, the upper portionof which is ttedA into the sleeve n, endretained therein by a. pin, la", fitted into one side thereof, and passing through a slot, c", in the side-of the sleeve.YV This stem is pressed downward by a spiral spring, s, situated within the sleeve, and 'has secured uponl its lower end the-atjpresserplato D. By moving the sleeve longitudinally u long the bar C, it may, bc'brought directly over the stuit. tobemonidcil, as vthe same passes from .the feed-rollers to the moulding-cutters, while-.by rnising'orqlowering the bar 7am -i 2 l C, by means of the screws m, the presser-platemay be readily adjusted, to suit`tlie thiclmess offthe stuff'on which it operates, by the pressure of the spring-s. j l

.Situated at the inner side of the standardsg 'are ports, E, furnished.with vertically-adjustable bearings, u which receivethe journals -of thecutter-hcad F. .Formed longitudinally in the bed A, underneathA the cutter- Vhead, are slots, zo, which extend quite through the be'd, vand are arranged sideby'side so as' to have the character of a grating. i

The cuttcrs,'one of which is shown at a*, are attached to the cutter-head, and are designed, as it revolves;

` to pass down into orlthrough one or the other of these slots w, 'according to theposition it may occupy upon t the cutter-head, the ollee of the slots' w being to permit theeutter to pass somewhat beyond the lower surface of the stati) informing the moulding onthe edge'of the latter, in order that ,the lower edge of such moulding 4may be 'made sha1-pand well defined, instead of ragged or irregular, as'would Vbe likely to otherwisebei the case, and, furthermore, topermit the chips or shavings out from the stuft' in the moulding-operation lto fall or pass ,awayfrom the immediate vicinity oi' the cutters, thus obviatipg'all danger which might otherwise exist of comm'unicating an irregular movement tothe stu''by the collection f the chips undeflia'tltliMdidigl-dl i ,lPlaoedat that side ofthe posts E, opposite that at which are situated the standards' g, are other standards,

A* 'which are'slotted vertically, and providedwith vertical adjusting-screwsjn the same rnaunerus thesltand ards g, andwhich serve to support a. horizontal longitudinally-slotted bar, B*,'corresponding lto the bar C of thestandards g, and vertically adjustable bythe vertical screws of the standards Af.` C* shousamovable rpiece, the upperend of which is reduced in size to pass through the slot of the' bar A*,a.n`d which, being formed with ,'shoulders, g', and providedat its up`per Vend witli'a locking-rscrew, 6*, maybe'iirmly-secured ,in aiixed position atany requisito part ot" the bar Al,`
