This invention relates to a new and useful improvenient'in the feed mechanism ofmachin'es for cutting moldings-those in which pressure-rollers are employed for feeding the .stuff to its work.

A Theinveution consists inthe employment or .use 0i' universal `joints applied tothe shaft of the lower .feed-roller, in.connection with a' swinging frame Ain which' the shaft of the Vnp-Vv per feed-roller is placed, and with gearing for operating said l'eedlrollers, all being arranged as Vhereinaite: 'ully shown and ldescrihed,

.whereby the hedk inwhieh one' ot' the 'cutterfv shafts istted may be odin sied higher or' lower, to suit the'thichness of the molding to he' cut,-

-withont at all affecting the-operation ofthe` feed-rollers, the latter performing their -fnnction equally as well'wh'ether thick or.tlii'nmold-A ings arebeiug cnt, and without requiring any specialadjustnient to'conipensatefor the-variations o 'f'the thickness vof the moldings.A

A represents the fraini-ng of the inachine, which may be constructed inany proper mann. nerto suppcrtthe working parts; andBis an adjustable or rising-and-fallingb`eclf piece, which is attached toot-1e -side of -theifraniing-JA- in: such a manner thatit may he adjusted :higher orlower as desired. This'may bejperiorlned by means yofascrew, Q, tted` vertically inf the frannng A', and passing throughv a nnt,` a, at-

tached to the `bed-piece, as shown in Fig. 5.

I) represents a cutter-head, which is placed at one end of a horizontal shai'tyE, ou the 'framing A, and D is a cutter-'head placed on the upper end cfa vertical shaft, F, in the hed-piece. This arrangement is oid, and forms no partdot' iny inventiou. .1.

vThe cutters operate in` the usual manner,

cutting.the-.molding in the desired form, the.

sticli or' stuft' being fed along on the .hedfpiece B, underneath the cutter-head D, and by 'the `side of the'cutter-head D. by means of feed'- rolle-'rs Gr' G', placed one over. the other, as shoivn in Figs.']. and 4.
