drawings, and pointed out in the appended claims.
In the drawings, forming a part of this application, and in which like numerals To all whom it may concern:
Be it known that I, WESLEY D. I'IOTCH- KISS, a citizen of the United States, residing at Ithaca, in the county of Tompkins and State of New York, have invented certain new and useful Improvements in Gages, of
which the following is a specification.
My invention relates to new and useful improvements in gages and more especially to such a gage used in connection with a scroll or band sawing-machine and consists primarily of a small attachment removably and adjustably secured to a convenient part of such a machine.
The object of my invention is to provide a gage for use in sawing circular forms and by the simple adjusting of which the sawing of circles of any desired diameter may be readily accomplished without the necessity of previously marking out the work and whereby any number of cuttings may be made without re-adjusting the gage.
A further object is to provide adevice that insures greater speed and accuracy in the performance of such work, is easily adjusted without the use of tools and acts as a safety device in that the operator is required to approach no nearer to the saw than the length of the radius of the circle in which the saw is traveling.
The devices now in use are found to be inconvenient and unhandy in operation and adjustment, and it is now intended to provide such a device for carrying out the said desired functions and advantages that is exceedingly simple and cheap to manufacture and which at the same time is of small weight and size, yet durable, and perfectly accomplishes the objects herein set forth.
0 While the forms of the invention herein shown and described are what are believed to be preferable embodiments thereof, it is throughout the several views, Figure 1 1s a front elevation of a band sawing-machine,
having my improved pattern gage attached thereto; Fig. 1 is a fragmentary side view thereof; Fig. 2 is a plan view of my device, disconnected from the machine; Fig.
3 is a side elevation of the device.
Referring in detail to the drawings, a common form of band sawing machine is illustrated to most clearly show the use of my device in connection therewith; the numeral 6 designates the machine frame, provided with the usual two supporting wheels 7-7, over which passes the band saw 8; adjustably secured to the frame 6 by the screw 9 is the L-shaped saw-guide bracket 10 and horizontally positioned below the latter is the saw table or bed 11. A bar or tubing 12. bent in the form of a right-angle, is provided, having its two sides of either equal or unequal length as desired, one end of the same being retained by the adjusting screw 13 in the smaller perforation 14; of a castiron block or double collar 15, the latter having parallel perforations, 14 and 16, of unequal diameters. The block 15 is in turn slidably mounted upon the saw guide bracket 10 and adjustably secured by the thumb-screw 17; the perforation 16 being adapted to receive the upright end of said bracket 10. Upon the opposite end of the right-angled bar 12 is slidably mounted the in-block 18, being adj ustably held thereon by the thumb-screw 19. Vertically positioned in said block 18 and at right angles to the adjacent end of the bar 12 is provided a suitable center-pin 20, having a head 21, to be understood that the same are susceptipreferably made removable and tightly fitble of various changes in the form, proporting or screwed within a bore of said block.
45 tion and minor details of construction and With the board 22, to be worked upon, v the right is therefore reserved to modify lying flat upon the saw table 11, a slight or vary the invention as falls within the pressure of the hand upon the pin-head 21, spirit and scope thereof. 7 will slightly depress the point of the center- With these general objects in view, and ing pin 20 into the said board, whereby the 50 others, which will appear as the nature of latter may be easily revolvedin the sawing the improvement is better understood, the operation with the said pin constituting the invention consists, substantially, in the novel center of the cutting circle. To firmly hold construction, combination and arrangement the pin in such engagement by use of the left of parts, which will be hereinafter fully dehand and to forcibly revolve the board in 55 scribed, illustrated in the accompanying contact with the cutting saw by the right of reference indicate corresponding parts so point, which is a greater distance tion of the centering preferable mode of operation. It will be seen thatthe nearest point that the operator is required 1 to approach the saw is the centering pin, as the board must necessarily extend beyond the latter and may be revolved at such a, from the saw than the said center. i My gage is easily attached to the band saw machine by first loosening the screw 9 and temporarily removing the saw guide bracket 10. The upright portion of said bracket then being inserted through the opening 16 of to its original position. The block 15 is the block 15, the said bracket is returned secured in any desired position upon the saw guide by the screw 13 and when not in use may be positioned rearwardly and out of the way as shown by dotted lines in Fig. 1. Vertical adjustment is secured by means of the thinnb-screws 13 and 17 but for positioning the centering pin 20 at any desired distance from the saw, the adjusting screw 19 is employed, the pin-block 18 being capable of a sliding lateral movement upon; the horizontal arm of the bar 12, lying parallel to the saw table. The size of the circle that may be cut with the aid of mv j l l gage is limited only by the length of the arms of the rod 12 and the size of the saw table; a circle of any size may be cut whose radius is equal to or less than the distance from the saw and the extreme outward posi- From the above description it will be understood that pivotal adjustment of the gage is had both at the point of connection with the bracket 10 and at the point of connection of the bar 12 and collar 15; that a vertical adjustment is had at the same points, and that a horizontal adjustment of the centering pin may be had on the horizontally-extending arm of the bar 12. By this construction I am able to provide for a positioning of the centering pin at any point within the extreme outer position of the pin with the collar 15 and bar 12 in extended alinement and a point where the pin is in close proximity to the saw, the lat ter position being obtained by moving the collar pivotally on the bracket and moving the bar 12 pivotally so as to bring these parts in juxtaposition to a superposed alined position, thereby permitting of a wide variation in position of the centering pin] Furthermore, this particular form of adjustment of parts is especially desirable in connection with band saw structures where the bracket is spaced from the path of travel of the saw to any appreciable degree, since --p ermi-ts of the double ';.pivotal movement. of the p r a freedom of adjustment, without bringing theminto close proximity to the saw, not possible where the adjustment is confined to a single point.
Having thus described my invention, what I claim as new is:
1. The combination with a band-saw having a saw-bracket, of a gage therefor, said gage having a vertical adjustment at one 7 end on said bracket, and also having a point of vertical adjustment intermediate the centering-pin and the point of connection of the gage and bracket, said gage also being adjustable pivotally in horizontal 7 planes at said points of vertical adjustment.
2. In a band-saw, the combination with the saw-guide bracket, of a gage carried by and adjustable vertically of said bracket, said gage comprising two members having a relative vertical adjustment, said gage being movable pivotally on said bracket, and said members also having a relative pivotal movement, said pivotal movements being confined to horizontal planes, and a center- 8 ing pin carried by one of said members, said pin being adjustable thereon in a horizontal plane.
8. In a band-saw, the combination with the saw-guide bracket, of a gage therefor, said gage being adjustable longitudinally of said bracket, and also adjustable in a direction extending in parallelism with the plane of adjustment on the bracket, said gage being movable pivotally at each of 19 said points of adjustment, the pivotal movements of the gage being confined to movements in planes extending at right angles to the direction of length of said bracket.
4. A gage comprising two members, one 3 of said members being in the form of a right-angled bar, the other of said members being in the form of a collar having parallel openings extending therethrough adjacent to its ends, v adapted to pivotally receive one end of said bar, the other opening being of a size and shape to permit of a pivotal movement of the collar on a guide-bracket, a centeringpin carried by the free end of said bar-1:11
and adjustable longitudinally thereof. and. means extending into the openings of said collar to ad ustablv secure the members to gether and to the bracket.
In testimony whereof I affix my signature 1.
