Otherwise the arrangement shown in Fig. l is preferable for purposes of conserving space.
In addition to its simple and inexpensive construction, the improved marking device is exceptionally easy to handle and the numerals or letters may be changed quickly without the necessity of dismantling the whole marker. The sectional view of Fig. 2 illustrates particularly the manner in which the outer letter strips 2|] are securely wedged in place against accidental dislodgment by the action of the resilient or springy pad l6, and this view further illustrates the manner in which the strip [8 provides a smooth gliding surface facilitating easy sliding movement of the letters into and out of the frame.
The objects and advantages of the invention may be realized by other forms of construction, and the appended claims are intended to include all mod fications, rearrangements and reconstructions fairly coming within their scope.
Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:
1. An X-ray marking device including a frame having opposite grooves, an identification strip bearing ray-impervious indicia matter seated in said grooves, a resilient member arranged on said identification strip, a top strip arranged on said resilient member, and an outer indicia strip slidably fitted into said frame grooves on said top strip.
2. An X-ray stencil including an elongated .frame having opposite longitudinally extensive grooves opening into an end of the frame, a base strip having ray-impervious indicia thereon slidably fitted into said frame in the grooves thereof, a resilient strip arranged on the base strip, an outer strip having a substantially smooth sliding surface arranged on said resilient strip and having portions extending into said grooves, and a letter strip slidably inserted into the grooves of said frame from said end thereof on said outer sliding strip, said letter strip being constructed of a material having a substantially smooth inner surface adapted for sliding movement on the outer surface of said outer strip.
3. An X-ray marker including a frame of raypervious material having opposite longitudinal edge portions turned up to form parallel grooves opening into an end of the frame, parts of both said groove-forming portions being cut away at said end of the frame to provide an enlarged entrance into the grooves to facilitate insertion of indicia strips therein, and indicia means including a base strip and a top strip secured to an intermediate strip of resilient material and slidably fitted into the open end portions of said grooves as a unit, said top strip constituting a sliding support for letter strips insertable into said grooves through the open ends thereof.
4. A device of the class described including an open-ended frame of ray-pervious material, a base strip of ray-pervious material fitted into the open end of said frame and having mounted thereon identification characters of ray-impervious material, resilient means of ray-pervious ,material arranged in unobstructing position relative to the identification characters on the base strip, a top strip of transparent ray-pervious material arranged on said resilient means in said frame, and. a letter strip of transparent raypervious material carrying ray-impervious indicia thereon slidably supported on said top strip by insertion through the open end of said frame.
5. An X-ray marker comprising an identification strip including in assembly an elongated base strip of ray-pervious material, an elongated strip of ray-pervious resilient material secured to the base strip, and an elongated top strip of ray-pervious material secured to the resilient strip, a frame of ray-pervious material having opposite longitudinally extensive groove channels opening into an end of the frame, said identification assembly being fitted into said groove channels of the frame through the open ends thereof, and said resilient strip being arranged and constructed to yieldingly urge the top strip toward and against overlying portions of the groove channels, and a letter strip of a width adapted to fit into said grooves and of a length less than that of said frame, said letter strip being of ray-pervious material and having rayimpervious indicia thereon and being adapted to be slid into the open ends of said groove channels on said top strip, said top strip and resilient strip yielding to permit introduction of the letter strip into the channels and to permit sliding said strip into a desired position in which it will be secured against accidental displacement by bearing action of the resilient and top strips as aforesaid.
6. In an X-ray marker of the type employing a ray-pervious frame having opposite slide grooves in which changeable letter characters are arranged, an identification base strip assembly comprising a bottom strip of a size adapted to slide into said frame, a strip of resilient material secured to the bottom strip, and a top strip secured to the resilient strip, said assembly of bottom, resilient and top strips being slidable as a unit into and out of the frame grooves, said letter characters being slidable into and out of the frame grooves on said top strip, the latter yielding cooperably with the resilient strip to permit ready sliding movement of the letter characters into and out of the frame and being effective by action of said resilient strip to press said letter characters securely in desired posiions in the frame.
'7. A changeable letter carrier including a frame having opposite elongated grooves opening into an end of the frame for insertion of letter characters therein and means providing a resilient supporting base for the letter characters and including a bottom strip and a top strip joined to a central strip of springy material in superposed relation for movement as a unit into and out of said grooves, said central strip of springy material normally urging said top strip into pressing engagement with confronting portions of said grooves, said top strip being yieldable to pressure cooperably with said central strip to permit introduction of said letter characters into said open ends of the grooves for adjustable sliding movement of said characters in said frame on said top strip, said top strip coacting with said central strip of springy material to urge said letter characters against parts of said grooves, whereby the characters are secured in adjusted positions in the frame.
