LENS FOR LINE CASTING- MACHINES Filed Jan. 28, 1951 2 Sheets-Sheet 2 Patented Dec. 13, 1932 GUSTAVUS ADOLPH BRADFORD, F BEMIDJI,,MINNESOTLA LENS FOR LINE CASTING MACHINES Application filed January 26, 1931. Serial No. 571L407.
This invention relates to new and useful improvements in lenses for line casting machines and has for its primary object the provision of a device of the above stated character, wherein the matrix line in the assembling elevator chamber of a linotype or intertype machine may be magnified to suit the eyes of the operators and relieve the eyes of undue strain, which heretofore has impaired the eye- 19 sight or vision of many operators, causing the health of the operators to be affected to such an extent that errors are frequent and conse quently cause slowing down of production and quality of work.
Another object of this invention is the provision of a supporting frame having a suitable lens and adapted to support the lens at various positions to suit the individual wishes of operators and which will not interfere with the operation of the machine or the operator when desiring to reach the matrix line to make corrections or adjustments.
A further object of this invention is the provision of a lens for linotype, intertype and similar machines of the above stated character which shall be simple, durable and etficient and which may be manufactured and sold at a comparatively low cost.
WVith these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference will be had to the following description and accompanying drawings in which:
so Figure 1 is a side elevation illustrating the assembling elevator of a type setting machine with a lens attached thereto and constructed in accordance with my invention.
Figure 2 is a plan view illustrating the lens and its support.
Figure 3 is a detail end elevation illustrating the adjustment of the lens relative to the support.
Figure 4 is a sectional view taken on the line 4-4 of Figure 2.
Figure 5 is asectional view taken on the line 5--5 of Figure 2.
Referring indetail to the drawings, the numeral 1 indicates an assembling elevator of a type setting machine of a well known construction and which has the usual scale 2 for measuring'thematrix line. The foregoing description relates to a well known construction of elevator and in use has proven objectionable to operators owing to the se- Vere eye strain imposed on the operator by having to watch the matrix so closely and to overcome these objections my invention has been provided.
The frame 3 including'channeled end and side members 4 and 5 receives a suitable magnifying lens 6 which is yieldably supported in the frame by springs 7 The springs 7 have one of their ends secured to the end members 4 of the frame as shown at 8 while their other ends have slidable contact with the inner walls of the members 4 thereby forming an efficient cushion for each of the lugs within the frame. The end members of the fra-me have screw threaded arms 9 adapted to extend through slots 10 of brackets 11 and receive adjusting'nuts 12. The brackets 11 are provided with parallel portions 13 and substantially L-shaped portions 14 which have their free ends secured to the elevator gate 1 by screws 15. The adjusting nuts 12 permit the lens 6 to be adjusted toward and from the matrix line and tilted with respect to said matrix line. By the lens having adjustment toward and from the scale and matrix line permits the magnifying ofa scale and matrix line to be varied to suit the individual visions of operators. Adjustment of the lens and about a horizontal axis relative to the elevator compensates for the peculiarities of posture and style of individual operators.
The lens when properly adjusted will magnify the matrix line to such an extent that the eyesight of the operator may not be strained and the lens and associated parts will not affect the operation of the elevator and will permit the operator to have the usual freedom'in making adjustments and corrections to the matrix line. The lens is carried directly by the elevator and moves with the same to not interfere with the operator when desiring to make adjustment to the matrix The device is primarily designed for use and benefit of linotype or intertype operators while it will be found equally efiectivewhen used on any machines when operators are subject to close observation when watching fine work.
While I have shown vand described the preferred embodiment of my invention it will be understood that minor changes in construction, combination and arrangement of parts may be made withoutdeparting from the spirit and scope of the invention I as claimed.
,Having thus described the invention what I claim is: i i
1. A device of thecharacter set forth comprising an open frame, a lens carried by the frame, cushioning means for each end of said lens and adapted to retain the latter in the frame, arms adj ustably secured to the frame and secured to the assembling elevator of a type setting machine. 7' i 2. A lens for line casting machines comprising a frame including channeled end members connected by a channeled member, a lens removably mounted in said members, and. means for adjustably securing the frame to the assembling elevator of a type setting machine.
3. A lens for line casting machines comprising a frame including a U-shaped channeled member, a lens mounted in said member, cushion means between the uprights of said member, and the lens to removably secure said lens in the frame, and means for 'adjustably securing the frame to the assembling elevator of a type setting machine.
- In testimony whereof I afiix my signature.
