4 Claims. l
This invention relates to new and useful improvements in instruments for marking and lettering and the primary Object of the present invention is to provide a novel and improved fou tain type brush that is particularly designed for marking or lettering in clearly visible indicia in a convenient manner on fabrics, paper or the like.
Another important object of the present invention is to provide a marking and lettering instrument including a liquid receiving chamber, a marking tip, and embodying novel and improved valve means for controlling the ilow of liquid from the chamber to the marking tip.
A further object of the present invention is to provide a marking and lettering brush that is small and compact in structure and which is quickly and readily assembled or disassembled to facilitate the repairing or cleaning of parts thereof in a convenient manner.
A still further aim of the present invention is to provide a marking and lettering brush that is simple and practical in construction, strong and reliable in use, neat and attractive in appearance, and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a perspective view of the present marking and lettering brush, and showing the closure removed therefrom;
Figure 2 is a perspective view of the closure used in conjunction with the present invention;
Figure 3 is a longitudinal vertical sectional view taken substantially through the center of Figure 1; and
Figure 4 is a similar view of Figure l, and showing the outer wall of the iluid chamber removed therefrom.
Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral l represents a substantially frusto-conical valve housing having a reduced annular extension l2 at its major end. The housing It is provided with an axial bore I4 in its lower end that terminates in an enlarged retaining chamber i6 having an inwardly placed, annular portion I8 at the inner extremity of the reduced extension l2. The lower Wall 2l! of the seat I6 is centrally raised and supports a closure disc 22 preferably of plastic material that closes the inner end of the bore I4.
Engaging the inner face of the disc 22, is an annular valve 24 that is rigidly secured to one end of an elongated valve stem 26, the longitudinal axis of which is inclined relative to the longitudinal axis of the valve housing'lil.
The numeral 28 represents a substantially cylindrical chamber or barrel preferably of plastic material one end of which is open and frictionally engages the reduced end portion I2 of the valve housing I9. Removably positioned in the cylindrical chamber 28 is a resilient, tubular inner wall 36 that is closed at one end 32, and open at its opposite end for positioning between the open end of the chamber 28 and the reduced end I2 of the valve housing I9.
The chamber 28 is provided with a pivotal lever 34 which when pivoted in one direction will actuate a hinged pressure plate 36 within the charnber 28 to depress the resilient inner wall 3B and pivot inwardly the free terminal 38 of the valve stem 26 that engages the inner periphery of the inner wall 33. An arcuate spring 4l) fixed within the chamber 28 engages the pressure plate 36 to normally retain the same in an inactive position away from the outer periphery of the inner wall 30. f
The numeral 42 represents a clothing engaging closure cap that is internally threaded at its open end 44 for receivably engaging the externally threaded open end 4B of the chamber 28. When applied to the chamber 28, the cap 42 loosely embraces the housing I0 and a marking tip or point 48 of preferably felt material that is frictionally positioned in the bore I4 and a portion of which projects therefrom.
Loosely embracing the valve stem 26 and biased between the ared annular portion I8 and the valve 24, is a coil spring 50 that normally urges the valve 24 to a closed position and the free terminal 38 of the valve stem against the inner periphery of the inner wall 3D.
In practical use of the present invention by actuating the lever 34 against action of the spring 40, the pressure bar or plate 36 will be pivoted inwardly to depress the inner wall 30 and open the valve 24 so that the chamber or inner wall 30 may be lled with a suitable painting or inking fluid. When the lever 34 is released, the same will return to its normal position drawing the liquid into the inner wall 30. When the tip 48 becomes dry, a slight pressure against the same will open the valve and then feed a supply of liquid in the inner wall 30 to the said tip.
In view of the foregoing description taken in conjunction with the accompanying drawings it i`s believed that a clear understanding of the device will be quite apparent t0 those skilled in this art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.
Having described the invention, what is claimed as new is:
1. In a marking and lettering instrument including a valve housing having an axial delivery bore, said bore having an enlarged inner end portion including a centrally raised lower wall, a barrel carried by the housing and having a slot therein, a resilient cylindrical wall within said barrel and including an open end embracing the housing, a hinged pressure plate mounted between the barrel and the cylindrical wall, and a lever pivoted to the barrel and having an end portion received in said slot for moving the pressure plate against the resilient cylindrical wall; a valve controlling the axial opening, said valve comprising a member received in the enlarged inner end portion of said bore, a stem xed to said member and disposed at an inclined angle relative to the axial bore, said stem having an end portion bearing against the inner periphery of said cylindrical wall, said stem being moved to tilt the member on the centrally raised lower wall and open the bore upon pivotal movement of said lever in one direction, and means yield ingly urging said member toward the lower wall of the enlarged inner end portion of said axial bore.
2. The combination of claim 1 wherein said means includes a spring embracing said stem and having rst and second end portions, the first end portion of said spring bearing against said member, and an abutment on said housing for the second end portion of said spring.
3. The combination of claim 2 wherein said spring is substantially frusto-conical shaped with its minor end portion bearing against said member and preventing bending of the spring against the inner wall of the enlarged end portion during tilting of said member.
4. In a marking and lettering instrument including a handle having a slot, a resilient and elongated tube in the handle and having a closed upper end, a hinged plate mounted between the handle and the tube for depressing the tube, and a lever pivoted to the handle, and having an end portion received in the slot for moving the plate against the tube; a force-feed dispensing mechanism comprising a valve housing carried by the handle and having an axial delivery bore and a tip received in said bore, said bore having an enlarged inner end portion, said enlarged inner end portion being received in the lower end of said tube and including a centrally raised wall about the bore, a disk bearing upon the centrally raised wall and closing the bore, a valve plate bearing upon the disk, a stem xed to the valve plate and disposed at an inclined angle relative to said bore, said stem having an end portion bearing against the inner wall of the tube, said stem being moved endwise upon movement of said lever to tilt the valve plate and open the bore.
