AUXlLlARY STOP FOR TYPE WRITER CARRIAGES.
Spe cification ef Letteis Patent.
Patented June 11, 1907.
Application filed September 16,1904. Serial No. 224.763.
To all whom it nuty concern:
Be it known that 1, WILLIA R. Fox, a citizen of the United States, residing at the county of Kent, State of Michigan, have invented certain new and useful Improvements in Auxiliary Stops for T ype-Writer Carriages, of which the following is a specification.
This invention relates to improvements in auxiliary stops for typewriter carriages, although, of course, the sto canbe made use of as a main stop if desire The stop is specially adapted for use with tabulator devices for typewriters, like those described in my patent application Serial No. 206,684, filed May'6th, 1904.
The objects of this invention are: First: To provide an effective adjustable stop which can be readily removed and put in place, but whichis very securely held in place when in position on the carriage of the typewriter. Second: To provide an improved spring means for retaining the stops in position. Third: To provide an improved construction of stop which is very compact in use.
Further objects will definitely appear from the detailed description to' follow.
lhe objects of this invention are accom-- plished by the devices and means described in the following specification The invention is clearly defined and pointed out in the claims.
A structure embodying the features of my invention is clearly illustrated in the accompany-ing drawing forming a part of this specification, in which- Figure 1 is a-detail rear elevation view of a typewritlng machine with two of my improved stops in position, only portions of the frame work of the machine being illustrated. Fig. 2 is a detail plan view of the rear bar ofthe carriage with the stops in po- 3" is an enlarged detail inverted view of one of my improved stops, with poi; tions 'of'the rear-bar=O of the carriage. Fig. 4 is a transverse sectional view taken on line d l 'of Fig. 3,' showing other details of const'riiction. Fig. '5 is a side elevation view of one of the stops removed from the bar.
1 the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar letters of reference refer to similar" parts throughout the several views.
Referring to the drawing, in Fig. 1 the main parts of a typewriting machine are shown, being the main frame work A with its top plate A on which the carriage B is mounted. Arms B extendrearwardly from the said carriage and support what I have denominated the rear bar of the carriage. This baris provided with teeth like the teeth ona rack,
the teeth being preferably perfectlylsquare.
This bar is provided with the regular adjustable stops (3 at each end, and the usual swinging stop bar E is provided for engagement with the same. My improved auxplaced on this back rack iliary stops D D are in Fig. 2. In the bar C, as clearly appears preferredform, these auxiliary stops consist of apiece of sheet metal folded upon itself, with a transverse notch f cut upin the center, as clearly appears in Fig- 5, the sides of the plate being separated sufficiently to enter the notches between the teeth on the bar C, thus providing a wide base for the stop. The lower edges or lips of the notch rounded at f so that they can be readily crowded onto the back bar. A spring d, with a curved engaging ortion d, is placed within the stop and is he din position by the handle 1) above, which has a stud extending down through the spring which is riveted thereto. When the stop is crowded in place, the spring presses against the bar (land forces the opposite side-into close engagement with are the teeth of the bar C, and the projection d hooks under the bar and retains the stop so effectively in position that considerable force is required to remove it, thus making the stop verysecure when it is in place.
One of the sides of the plate is cut away at D so that but a single projection is presented as a stop. This is desirable where the sides of theplate are close together, as it permits the free. movement of the vertically adjustable tabulator bars described in my former application for patent above referred to. When my improved stop is used, it will be observed that .many st'ops can be very readily laced on theback bar (land that they wil be very effective in use.
By the particular formation of the spring, the stops are retained as'securely in lace for all practical purposes. as though t iey had been'screwed or riveted in position, and, at the same time, they are-readily removable and adjustable along the bar.
I have illustrated my invention in its most IIO approved form. The form of the same could be varied, so far as general features are concerned so long as the equivalent parts are provided with-the spring d and its engaging projection (1. Certain of the claims are, of
. course, to the specific approved form which I arranged to engage beneaththe back bar C and a handle D with a'stud riveted through the spring to hold it in position, .co-acting for the purpose specified. a
2. A stopD for a typewriter, adapted for use on the back bar 0 of the carriage, consisting ofja sheet of metal folded upon itself, with a transverse notch f therethrough having the lips to readily pass onto the notched ba'ckbarC of t e carriage, one of the lips be- .ing cut away at D a spring d to embrace the back bar and with a projection d ar ranged to engage beneath the back bar C; and ahandle'D with a stud riveted through the spring to hold it in position, co-acting for the purpose specified;
j 3. A stop D for a typewriter, adapted for use, on the back bar 0 of thecarriage, consist ing of a sheet of .metal folded upon itself, .with a transverse notch therethrough, hav- 7 i ing the lips toreadily pass onto the notched 9 back bar ,C of the carriage; a spring d to embrace the back bar and witha projection cl arranged to engage beneath the back bar C and a handle D with a stud riveted through the spring to hold it in position, co-actin'g for thejpurp ose specified. l

' 5. A stop D for a typewriter, adapted for use on the back bar 0 of the carriage, consisting ofa suitable body to embrace the back bar; a spring d to embrace the back bar and with a rojection (1 arranged to engage beneath t e back bar C and a handle D with a stud riveted through the spring to hold it in position, co-acting for the purpose specified.
6. a A stop D for a typewriter, adapted for use on the back b-ar C of the carriage, consisting of a suitable body to embrace the back bar; and a spring (1 to embrace the back bar= and-with a projection (1 arranged to engage beneath. the back bar C, c'o-acting for the purpose specified.
7. A stop for a tabulator adapted for use on the back-bar of the carriage of a type writing machine, consisting of a piece of metal folded upon itself and with a transverse slot f therethrough so that the edges of the sheet metal will engage between the teeth on the rack; a handle terminating in a rivet;
a, spring, with an engaging projection arranged within the said stopvand held in position by the rivet of the handle, for the purpose specified.
8. A detachable sheet metal stop folded to form two substantially parallel slot engaging I securing arms, each of said arms being bifurcated to straddle a supporting rod.
9. A-detachable sheet metal stop folded to form two substantially parallel slot engaging securing arms, each of said arms being bifurcated to straddle a supporting rod, and securing means carried by said stop.
10. -A detachable sheet metal stop folded to form two substantially parallel slot engage ing securing arms, each of said arms being bifurcated to straddle a supporting rod, and a clamping spring carried by said stop. In witness whereof, I have hereunto set my hand and. seal in the presence of two witne'sses.
