WILLIAM BATTENSBY, OF GATESHEAD, ENGLAND, ASSIGNOR TO THE LUMSDEN MACHINE COMPANY, LIMITED, OF GATESHEAD, ENGLAND.
MITERING-MACHINE,
Specification of Letters Patent.
Patented June 11, 1907.
Application filed January 30,1906. Serial No. 298,636.
To all whmn it vncty concern:
Be it known that I, WILLIAM BATTENSBY, a subject of the King of Great Britain and Ireland, and a resident of Gateshead, in the county of Durham, England, have invented certain new and useful Improvements in i\Iitering-i\Iachines, of which the following is a specification.
This invention relates to initering machines of the type which are generally known in the trade as wood trimmers.
At present in initering machines or wood trimmers the knife or cutter carriage is traveled in one direction, to bring one of the knives or cutting edges intooperation, by operating a handwheel or lever in one direction, and to bring the other knife or cutting edge into operation, by operating the handwheel or lever in the reverse direction. Now, as it is considerably easier for the operator to operate the handwheel or lever toward himself than away from himself, the knife or cutter carriage cannot therefore be operated with equal efficiency in both directions from one end of the machine.
The object of my invention is to provide means whereby the knife or cutter carriage can be operated in either direction without reversing the direction of operation of the handwheel or lever and thus enable the machine to be operated from one end in either direction with equal efficiency.
According to my invention I employ mangle-rack mechanism, said mechanism comprising two toothed racks inversely disposed in regard to each other, a toothed pinion adapted to be rotated by a handwheel or the like and suitable means for causing the pinion to co-act with one or other of the racks, the arrangement being such that, when the pinion gears with one of the racks, the knife or cutter carriage is traveled in one direction, while, when the pinion gears with the other rack, the carriage is traveled in the opposite direction. In some cases I may employ a separate pinion for each rack and suitable means for putting the pinions into and out of operation.
I will fully describe several forms of my invention with reference to the accompanying drawings wherein Figure 1 is a rear elevation, Fig. 2 a sec-' tion on the line XX therein, and Fig. 3 a sunllar new to Fig. 2 showing the parts in different operative positions. rear elevation and Fig. 5 is a section on the line YY therein. Fig. 6 is a rear elevation and Fig. 7 is an under plan (partly in section) of same. Fig. 8 is a cross section. Fig. 9 is a part rear elevation and Fig. 10 is a section on the line Z-Z therein.
In the drawings and in the following description like marks of reference indicate like parts.
Referring to the drawings, according to the arrangements shown in Figs. 1, 2 and 3, I attach to the knife or cutter carriage a two racks I) and 0 arranged one above the other and between the racks b and c I dispose a toothed pinion d which is attached to and adapted to be operated by a handwheel e. The pinion d and handwheel e are mounted and rotate on a bush f which is eccentrically mounted on a spindle or shaft 9 secured to the framing of the machine. The eccentric bush fis adapted to be turned on the spindle g, to engage the pinion d with one or other of the racks b and c, and to be locked in the required position by suitable spring or other catch such as h (engaging the spindle g or a flange thereon) which may also serve as a handle for operating the eccentric bush Thus, when the bush f is turned on the spindle 9 so that the pinion d engages the upper rack b and the handwheel e is rotated toward the operator as indicated by the arrow (Fig. 1), the knife or cutter carriage a is traveled toward the operator as indicated by the arrow (Fig. 1) and the knife or cutting edge m is brought into operation. When it is desired to bring the other knife or cutting edge n into operation, the bush f is turned on the spindle g until the pinion d disengages the upper rack b and engages the lower rack c, as shown in Fig. 3, when the rotation of the handwheel in the direction indicated by the arrow j (Fig. 1) as before will cause the knife or cutter carriage to travel in the opposite direction or away from the operator as indicated by the arrow 0 (Fig. 1) and bring the knife or cutting edge n into operation.
If desired and as shown in Figs. 4 and 5, I may reverse the disposition of the racks b and c and the pinion d, that is to say the racks b and 0 may be formed on or secured to the framing of the machine and the spindle g carrying the eccentric bush f, pinion d and handwheel 0 may be secured to the knife or cutter Fig. 4 is a V carriage a. In this arrangement the handwheel a will travel with the carriage a and the operation of the handwheel in the direction indicated by the arrow 7', Fig. 4, will cause the carrier a to move in the direction of the arrow 0 when the pinion d gears with the rack b, and in the direction of the arrow it when the pinion d gears with the rack 0.
Instead of the eccentric bush f I may employ other means for engaging the pinion d with one or other of the racks b and c. For instance, as shown in Figs. 6 and 7, the spindle 9 may be mounted in one end of a lever 19 pivoted at Q to a suitable point on the framing of the machine, said lever 12 being adapted to be turned on its pivot g to engage the pinion d with one or other of the racks b and c. The pivoted lever 3) may be locked'in the desired position by a pin adapted to pass through a hole 1" and one of a pair of corresponding holes 8 in the framing or by other suitable means.
In some cases I may employ a separate 0 f which .is loosely mounted and rotates on the spindle g. The pinions (Z and d are loosely mounted on the sleeve f but are adapted to be connected thereto as required, so as to rotate therewithand actuate their corresponding rack, by a sliding key If. When one of the pinions is being rotated by the handwheel e and the sleeve f to operate its co-acting rack to travel the knife or cutter carriage a in one direction, the other pinion is being freely rotated on the sleeve f by its co-operating rack and vice versa. Or, as shown in Figs. 9 and 10, the pi nions d and (1 may be formed or connected together and rotate with the sleeve f by means of a fixed key a, said pinions being adapted to be slid on said sleeve by a forked lever v or the like to engage and disengage the racks b and c.
What I claim and desire to secure by Letters Patent is 1. A hand-operated mitering machine or wood trimmer, comprising the combination with the cutter or knife carriage of manglerack mechanism for operating it, said mechanism comprising two inversely disposed racks and means for bringing one or other of the racks into operation.
2. In a mitering machine or wood trimmer, the combination of a frame, a cutter or knife carriage adapted to be reciprocated in said frame, lateral and oppositely inclined knives or cutters on said carriage, an operating handle adapted for manual use, and mangle rack mechanism connected with such handle for operating said knife or cutter carriage, said mechanism comprising two inversely disposed racks and means for bringing one or other of said racks into operation whereby said cutter carriage can be moved in either direction by a movement of said han dle in a single direction.
In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
WILLIAM BATTENSBY.
