Application filed ma 21,
This invention relates to gauges for mortising machinesand for other machines of this type,
Objects of commonly known. as. top back fence to hold the upper portion of the work down and to hold the rear faceof the work true with reference to vertical line, so, that the upper.
back gauge may beaccurately aligned with the lower back gauge,and thusthe mortise maybe out .true from its top to its bottom, irrespective of the. height or width of ,the work; i v
In actual. practice with ,mortising ma chines it has been found diflicult to-cut the mortise-in a wide piece of work. Usually the ordinary types. of mortising machines are. provided with a table with a back gauge which'holds the work. correctly at itslower portion, but which does not insure the accuracy of the top portion of the work. Obviously, therefore, an operator has consider able difiiculty in properly cutting the mortises in a true and accurate manner.
This invention overcomes the defects noted, and provides a simple and easily adapted device which may be quickly applied to standard machines, and which is so constructed that it does'not interfere with l the free operation of the machine but which insures the utmost accuracy and permits the rapid forming of mortises, even in relatively wide and ordinarily, diffioultly handled work.
An" embodiment of the invention is shown in the accompanying drawings in which Figure 1 is a front view of a mortising machine showing the device in position.
Figure 2' is a side view of the structure shown in Figure 1.
Fi ure 3 is an enlarged plan view of the attachment, such View being taken approximately on the line 33 of Figure 1, the parts of the mortising machine being merely inclicated in such view.
Referring to the drawings, it will be seen that a standard type of mortising machine has been illustrated with guides or ways '1, and with a bottom table 2, provided with a rear gauge or back stop, commonly known as a back fence, and indicated by the reference character 3.
of the usual mortising tools; for example,
thisiinvention are to provide a.- combination hold down and top back gauge, 7
. bolts 11 pass.
The mortising machine may employ any 1926. Serial No. 110,788.
the box chisel, as indicated at 4, such chisel which, in reality, is a plate overhanging the work 7 This plate slides upon the ways 1, and is-provided with guides 8 whichhold it in place. It may belocked in position in any suitable manner, as by means of a set screw .9, as most clearly shown in Figure 3. The bodypoi'tion 6 is provided with apair of parallel slots 10 through which clamping or marginal portions of these slots are formed of finished bosses 12, so that the screw heads orwashers carried by the bolts may have a perfect fit. Below thebody portionorhold down a back stop orback fence 13 is positioned and receives the lowerends of the clampingbolts ll lhus the back s op ybe a ju t With f 'en et th body portionG to accommodate any thick ness of work. Preferably, the body portion 6 is provided with a cutout 14 through its front edge to accommodate the mortising tool.
merely necessary to adjust the device to the correct height and to properly adjust the In using the device, for instance, to cut a Preferably the adjacent faces back stop or back fence 13, so that it aligns with the lower back stop 3. Thereafter it is merely necessary for the operator to rest the work upon the table 2 and hold it against the back stop. This insures a perfect alignment of the mortise with the work so that the utmost accuracy may be attained. Obviously, the operator may interchange the work rapidly and thus the machine may be used at its utmost capacity with assurance that accurately and correctly aligned mor tises will be formed.
It will be seen that a very simple and cheaply produced device has been provided by this invention, which may be veryquickly applied to standard types of mortising and similar machines, and which may be adjusted to accommodate any height or thickness of worlg It will be seen further that this device will insure the utmost accuracy of the mortise and will permit the rapid manipulation of the work.
It is to be understood that in the event that extremely wide work has to be mortised that the bottom table may be removed and suitable supports may be placed upon the floor for the reception of the Work.
Thus it will be. seen that the device may accommodate a wide variety of Work, and insure the desired accuracy.
Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scopeoit' such invention is to be determined as claimed.
I claim: 7
.1. An attachment for a machine having guides and havingan operating tool, said attachment comprising a body portion adapted to overhang the Work and-having a back stop mounted on its lower side, a pair ofslides carried by said body portion and slidably engaging the guides, and'means for locking said slides in position,
2. A combined hold down and top back fence comprising a body portion having guide receiving slides, and having a transverse backifence adjust-ably mounted upon its lower side.
3. In a 'mortising machine the combination of a mortising tool, mechanism for driving said tool, vertical guides, a bottom support carried by said guides and having aback stop, a holding down device adapted for positioning above said work and having slides for engaging said guides, said holding down device having means for looking it in position upon said guides, a transverse back stop mounted below said holding down vice slidably carried by said guides, means for locking said device to said guides, said device having a body portionprojecting outwardly from said guides and adapted to overhang the work, said body portion having a cutout to permit the passageof the mortising tool, and having a pair of parallel slots, a transverse bar forming a back stop and mounted below said body portion, and a pair of clamping bolts passing through said slots and adjustably locking said bar to said body portion.
In testimony that I claim the foregoingl have hereunto set my hand at Madison, in the county of Dane and State of \Visconsin.
