Letters Patent No. 101,550, dated April 5, 1870.

IMPROVED FEED FOR IRON-PLANERS.

The Schedule referred to in these Letters Patent and-making part of thesame,

To all whom it may concern Be it known that I, HORATIO B. WEAVER, of

' Hartford, in the county of Hartford, in the State of Connecticut, have invented a new and improved Feed- Motion for Iron-Planers, in connection with the beltshipping device; and I do hereby declare the following to be a clear and exact description thereof, and sufficient to enable others skilled-in the art to whic my invention appertains to fully understand and use the same, reference being had to the accompanying drawings making part of this specification, in which- Figure 1 is an elevation of such parts of an iron planer as are embraced in my invent-ion.

Figure 2 is an end view of the same parts asfig. 1.

Figures 3 and 4 are two views of the. stand 0, shown by dotted lines in both figs. l and 2.

Figures 5 and 6 are two views of the pinioneara, shown by dotted lines in both figs. 1 and 2.

Figures 7 and 8 are two views of the arm F.-

Figures 9 and 10 are two views of the peculiarsha-ped cam H.

Figure 11 is a view of gear Figure 12 is a sectional view of gear 7;, and also a section of dog-Wheel n attached.

Figure 13 is a view of the peculiar-shaped and recessed pieces h and h.

Figure 14 is a sectional view of the pieces hand h.

Figures 15 and 16 are two views of the dogs i and i.

Figure 17 is a view of shaft 1), pinion-gear a,'flanch d, and gear 0, in section.

The same letters and numerals designate the same parts in both views.

My invention relates to an improvement in the feeding-mechanism of iron-planeis, and is designed to more efiectually insure certaintyoi' operation and uniformity of feed in the cutting-tool.

A represents the bed or frame of an iron-plauer.

B represents the upright stand, or one of them, to

which the cross-head is attached, and by which the cross-head is supported.

0 represents the cross-head of an iron-planer.

D represents the table or platen of an iron-planer.

E is the sliding-piece that operates the feedingmechanism, through the medium of the arm F.

F is the arm that operates thecam H.

G is a stationary piece of a T-shape, and it is firmly attachedto the bed or frame. H is a peculiar-shaped cam, attached to the end of the rocker I.

J is a stud-bolt, and

K is a connection between rocker I through the medium of the stud p.

L is a rack, by means of which a reciprocating rotary motion is given to the-feeding-mechanism.

a is a pinion-gear, attached to the end of shaft 7), and is shown by dotted lines in bothfigures.

and rack L,

b. is a shaft fitted into the stand 0. '0 is a stand attached to the back of the cross-head C, and is shown by dotted lines in both figures.

(1- is a fiauch attached firmly to shaft 1).

e is a gear fitted loosely on shaft 1), and is recessed on one side sufiicient to receive and cover fianch (l.

Gear 0 is held in its place by the'screw-nut f.

g represents the feed-scrcwin the cross-head of an iron-planer.

h and h are two peculiar-shaped and recessed pieces, that carry the operating'feed-dogs land l, and are both of them firmly attached to the pinion j.

k and l are spur-gears. k is fitted loosely on screw g, and l is firmly attached to one end of rod m.

m represents the feed-rod for operating the vertical feed of an iron'planer.

n and 0 are toothed dog-wheels, for the dogs i and l to act upon.

dog-wheel a is attached to the geark, and serves the purpose of operating the vertical feed of a planer, by means of the gears It and l and the rod m.

dog-wheel o is securely attached to the screw 9, and serves the purpose of operating the cross or horizontal feed of an iron-planer, by means of the dog It will be seen by referring to the drawing that the parts It and h are each of them deeply recessed upon one side, and inclose in the recesses above referred to, the dog-wheels n and 0.

By further observing the drawing, it will be seen that there is a pin in the stem of the dogs l and i, resting in a receptacle provided in one end of each of the pieces h and 71-.

The object and purpose of this pin is to hold the dogs 1 and t in any desired position, whether that position be in contact with either dog-wheel or disengaged from either.

The numerals 1, 2, and 3, not before referred to, represent certain parts, as follows:

1 and 2 are movable stops, attached to the edge of a table or platen of an iron-planer.

3 is a stationary stop, attached to the sliding piece E, and serves to operate the whole of the above combination, when acted upon by the/movable stops 1 and 2.

Having referred to all of the essential invention, 1 will describe its operation.

The table or platen being operated in any manner, causes the movable stop 1 to engage the fixed stop 3, carrying the sliding piece E with it sufiiciently far to operate the beltshipping device,- (not shown,) thus causing the table or platen to move in the opposite direction, (by suitable gearing,) and as a consequence, carrying the sliding piece E with it, by means of the movable stop 2 engaging fixed stop 3.

This alternate reciprocating motion of the sliding piece E causes the arm F to engage one of the points parts of my of the cam H, marked in the drawings 4 and 5 on the arm, and 6 and 7 on the cam H.

To be more definite, the first-described movement of the table causes the point 5 on the arm F to engage with the point 6 on the cam H, rotating it in the same direction that the arm F is moving, and as a consequence of this the rocker I is depressed at one end of its arm, carrying the connection K down, and with it the rack L, by means of the stud 12, thus causing the pinion-gear a to revolve partially, carrying gear 0, with the pinion j, with it.

Now, as both the'pieces h and h are firmly attached to pinion j, any movement of j carries h and h with it; consequently, if either of the dogs i or t" are in contact with its appropriate dog-wheel, that feed, be it either vertical or horizontal, is operated bythe medium of the screw 9 and dog-wheel o, in the case ,of the horizontal feed at g is attached to the tool-holder of a planer in the usual manner, or through the medium of the gears k and l and the rod on, in the case of the vertical feed insuring a certain and uniform action of the cutting-tool. a What Iclaim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the peculiar-shaped and recessed pieces or dog-holders h and h, dogs i and i, and dog-wheels n and o, with the pinions j, k, and l, and the shafts 1n and g, as and for the purpose set ort-h.

2. The combination of the arm F, cam H, rocker I, connection K, rack L, pinion-gear a, shaft 11, stand 0, flaneh (1, gear e, pinion j, together with the peculiarshaped pieces h and h, the dogs and i, and dogwheels n and 0, the whole operating together, as and for the purpose herein set forth.

- HORATIO B; WEAVER.
