6 Claims. (Cl. 12S-23) This invention relates to improvements in a safety paper spindle.

The principal objects of this invention are; First, to provide a novel form of spindle for receiving record papers, bills and the like in which the piercing end of the paper receiving spike is protected by a guard member for preventing the users hand from becoming engaged with the spike and in which the guard member is easily swngable out of guard position for removal of papers from the spike.

Second, to provide a paper spindle with a guard member which is spring urged to swing in the plane of the spike to operable guarding position.

Third, to provide a novel and inexpensive form of spring mount for the swinging member of a safety paper spindle.

Fourth, to provide a safety paper spindle with a spring mounting for the guard member which is easily and securely fastened to the guard member without the use of tools so that the spindle may be packed in disassembled condition to obtain saving in shipping space and can be easily assembled by the users.

Fifth, to provide a safety spindle which can be manufactured at extremely low cost with a minimum number of parts.

Other objects and advantages pertaining to the details and economies of our invention will be apparent from the following description and claims.

The drawings of which there is one sheet illustrate a preferred form of our safety spindle.

Fig. 1is a side elevational View of the spindle in erected operative position.

Fig. 2 is a plan View of the under side of the spindle.

Fig. 3 is a fragmentary vertical cross sectional view through the base of the spindle taken along the line 3-3 in Fig. 2.

Fig. 4 is a fragmentary perspective exploded View of the guard member and its supporting spring employed in the spindle.

The spindle consists generally of a base I on which is mounted the paper impaling spike 2 and a swingable spring mounted guard rod 3. The upper end of the guard rod is turned forwardly over the top `of the spike 2 and provided with a guard nob 4 preferably formed of plastic or other moldable material. The nob 4 is shaped with a rearwardly and downwardly inclined under surface as at 5 to guide papers over the end of the spike. The nob is spaced from the end of the spike so as to substantially prevent the entry of the users hand or ngers between the nob and spike as is indicated in Fig. 1.

The upper surface of the base I is shaped to provide an attractive'appearance but is preferably formed with downwardly extending marginal flanges 6 defining a recess on the under side of the base. The under side of the base is formed with a pair of laterally spaced depending ears 'I and a pairof laterally spacedvbosses B positioned longitudinally forwardly of the ears I. Forwardly of the bosses 8 and'along the center line between the ears and bosses the base is provided with a thickened portion 9 defining a tapped aperture I0. The flanges 6 are thick` ened at the corners of the base as at II and define downwardly openingapertures I2 for re ceiving the Shanks of rubber pads I3 which form nonmarring feet for `the spindle.

The top wall of the base defines `a longitudinally extending slot I4 opening to between the ears 'I and adapted to pass the lower end of the guard rod 3. The lower end of the guard rod is partially cut away on its rear side'as at I5 and is received through a slot I6 in the rear end of a leaf spring I'I. The rear end of the spring I'I-is downwardly Iianged as at I8 to bear against the vertical surface of the cut away portion I5 and forwardly turned ears I9 on each side vof the flange I8 arearranged to engage the lower end of the guard rod and prevent its tilting relative to the spring I'I.` The slot I6 is formed in the spring I'I by striking downwardly the tongue 20, the rear edge of which engages and grips the lower end of the guard rod to hold the rod in yengagement with the spring.

The forward end of the spring I'I extends between the bosses 8 on the base and is secured against the under side of the base by staking or swaging over the opposed edges of the bosses 8 as at 2I (see Fig. 2). The forward end of `the spring II is provided with an upwardly turned ear 22 received in a recess 23 provided therefor in the under surface of the base to the rear of the thickened portion 9.

. The base isfconveniently formed as a casting and preferably is completed to include the feet I3,spring I'I and tapped aperture IU.` The spindle can be packed and shipped r with the spike and guard rod disassembled to permit the use of a small carton. The user can thread the lower end of the spike into the aperture .IIIy and push the lower end of the guard r-od through the slot I4 in the base and the slot in the spring tilting and the forward end of the slot I44 forms a stop for limiting forward tilting of the guard rod.

We have thus described a highly practical form of our paper spindle which is extremely inexpensive to manufacture and easy and safe to use and unload. We intend this description to be an example only of our spindle as certain modications of its structure can readily be made to suit the taste of the manufacturer without departing from the scope Iof the invention. Obviously the spike rather than the guard rod could be yieldingly mounted if desired.

Having thus described our invention, what we claim as new and desired to secure by Letters Patent is:

l. A safety spindle including a base having spaced bosses on the under side thereof, a spike, a guard rod, said base defining a tapped aperture receiving the lower end of said spike and a slot spaced from said aperture tiltably receiving the lower end of said guard rod, a leaf spring having one end secured to the bottom of said base by staking over said bosses, the free end of said spring projecting under the end of said slot and having a down turned flange, a finger struck downwardly from the free end of said spring to define a second slot the end of which overlaps the end of said slot in said base, the lower end of said guard rod being notched and received through said slot in said spring with said flange bearing against the edge of said notch and with said tongue springably gripping the opposite side of said guard rod from said notch, ears turned from the lower edge of said fiange and arranged to engage the side of said guard rod, a forwardly turned upper end on said guard rod, and a guard head secured to said forwardly turned end in closely spaced relationship with the upper end of said spike.
