Oct. 27, 1953 F. SCHLIEDER CHALK HOLDER OR THE LIKE Filed Feb. 11, 1952 4 w w w m m m N m 6 m H ATTORNEY Patented Oct. 27, 195 3 UNITED STATES PATENT OFFICE CHALK HOLDER OR THE LIKE Leland F. Schlieder, Manchester, Vt. Application February 11, 1952, Serial N 0. 270,931
.My invention relates to improvements in chalk holders or the like and while it has particular reference to a multiple stick holder, it is not to be understood as limited thereto.
Briefly and generally stated, the invention has for its primary object to provide a device as characterized wherein one or more chalk stick holders are removably carried by a hand grip-providing base in a novel manner which admits of some transverse yield between the holder or holders and the base when the device is in use so as to compensate for irregularities in the blackboard surface and to make breakage of the chalk sticks less likely.
Additionally, the invention contemplates a device of this kind which is simple in construction, economical to manufacture and highly efiicient in practical use.
The invention also resides in certain novel features of construction, combination and arrangement of the various parts and in modes of operation, as will be appreciated by those versed in the art upon reference to the accompanying drawing in connection with the detailed description thereof to follow.
Although I have illustrated my invention in its now preferred form, it is to be understood that same is susceptible of other mechanical expressions within the spirit and scope of the subject matter claimed hereinafter.
In the drawing, wherein the same reference characters have been used to designate the same parts throughout the several views- Fig. l is a perspective view of a chalk holder embodying my invention;
Fig. 2 is a cross sectional view through the hand grip-providing base adjacent one end and illustrating one of the chalk stick holding units in longitudinal section;
Fig. 3 is an end elevational view of the device, the dotted lines illustrating how the chalk stick holders are adapted to yield relatively to the base when the device is in use;
Fig. 4 is a perspective view of a rubber seating collar which is embodied in the invention; and
Fig. 5 is a perspective view of one of the chalk stick holders detached and with the gripper ring removed.
Referring to the drawing by reference characters, numeral 6 discloses an elongated base member which is generally rectangular in cross section and has the longitudinally coextensive cutaway or bevelled top and bottom front and rear edge portions 8, l as indicated, for instance, in Figs. 1 and 2.
.- mension of the Suitably secured to the top portion of the base member 6 is a bar-like hand grip member 9 whose top and bottom edges are cut away or bevelled as indicated at H, ill in Figs. 1 and 3. The cut away portions 8, ID of the base and hand grip member provide the finger receiving groove or recess I2 as suggested in Figs. 1 and 2.
In carrying out the invention the base 6 has, as suggested in Fig. 1, a longitudinal series of spaced bottom surface recesses l3, one of which is illustrated in Fig. 2 as receiving the rubber or other resilient collar H.
The central hole of each collar I 4 receives the diametrically larger pintle extension iii of a chalk holder 16 whose wall is preferably away as indicated at 16a adjacent the pintle l5, so as to cooperate with the adjacent bevelled portions 1 of the base 6 to provide a relief area 22 of considerable width adjacent the outer end of the collar I4.
Considering now the chalk holders l6, per se, it will be noted that they are illustrated as being round in cross section, although this is not necessarily the case. The exterior cross sectional diholders l6 increases from the bevelled inner end outwardly as will be appreciated from an inspection of Fig. 2, which also illustrates the socket I1 in the solid portion outwardly of the pintle l5. The socket ll of the chalk stick holder provides a seat for the inner end of a chalkstick 20, said seat indicated.
Outwardly of the socket l1, each holder I6 is provided with circumferentially spaced lineal being of considerable depth as splits H! which provide the plurality of fingers l8.
The holder I6 has been drilled or bored inwardly from its outer end so that the fingers l8 cooperate to provide the bore Ila as an extension of the socket H.
To confine the chalk sticks 20 in place in the holders I provide the clamping rings 2| which draw the fingers l8 into tight contact with the chalk sticks when moved outwardly to the Figs. 2 and 3 positions. In view of the yield of fingers l8, pieces of chalk of different lengths can be readily secured in place.
From the foregoing description read in connection with the accompanying drawing, it will be appreciated that I have provided a very eflicient and inexpensive chalk holder which may b employed for drawing one or a plurality of lines on a blackboard or the like. The device has many uses, one being to draw the lines of a music stall on a blackboard.
Blackboards do not ordinarily present even surbevelled or cut faces. Thus, if there is no give in the connection between the chalk stick holders l6 and the base 6 one stick 20 may not make a continuous line when the device is drawn along a blackboard slanted in the direction of travel. I meet this situation by the yielding sleeves M which permit the respective holders to give slightly as indicated in dotted lines in Fig. 3 under pressure applied by the operator. Thus, each chalk stick 20 will be forced against any depression surfaces in the blackboard when the device is drawn along the same under pressure and slanted forwardly or in the direction of travel.
The rubber collars 13 of providing a precision fit of the pintles 15 in recesses in the base member 6.
also obviate the necessity I It is believed that the foregoing will-enable those versed in the art to readily understand and appreciate the advantages of the invention presented.
Having thus described my invention, what I claim is:
. 1. In a chalk holder or the like, the combination of. a handgrip-providing base member, a
chalk stick holder, said base member having a seat-providingrecess closed at its inner end, av
resilient seat member positioned in and engaging the side walls and inner end of said recess, said seat member having. an outwardly opening hole, and amounting portion carried by saidchalk stick .holderand frictionally engaged in said seat member hole, said mounting portion having a cross section but slightly greater than the cross section of said hole, whereby the chalk stick holder isremovably mountedfor slight universal lateral yieldingmovement when in use.
. 2. In a; chalk holder or the like, the combination oi-a hand grip-providing base member, a chalk stick holder, said: base member having aseatproviding recess closed at its inner end, a resilient seat member'positioned in and engaging the side walls and inner end of said recess,. said seat member having an: outwardly opening hole, a mounting portion: carried by said chalk stickholderand frictionally engaged in said seat mems ber hole; said mounting, portion having. a cross section but slightly greater than the cross section ofsaid hole; whereby the chalk stick holder is, removably mounted for slight universal lateral yielding movement when in use, and said" mounting portion being of greater cross section than said seat member hole whereby to compress theexterior side surfaceportions of seat member tightly against the opposed recess. walls so as.
to retain the seat member'and' chalk stick holder assembled with said base.
3. In a. chalk holder or the like, the combination of ahandgripeproviding base memberha'v- 4 ing a lineal series of spaced recesses in one surface, each recess closed at its inner end, a series of independent chalk stick holders, a resilient seat member positioned in each recess and engaging the side walls and inner end thereof, each of said seat members having an outwardly opening hole, and a mounting portion carried by each of said chalk stick holders and frictionally engaged in one of, said seat member holes, each of said mounting portions having across section but slightly greater than the cross section of the related hole, whereby each chalk stick holder is removably mounted for slight independent lateralmovementin opposite directions transversely of said recess series.
4: In achalk holder or the like, the combination of ahand grip-providing base member having a lineal series ofsuriace recessses each closed at" its inner end, said series of recesses spaced inwardly from opposite side edges of said base member, a; series of independent chalk holders having cross sectionally reduced mounting eX- tensions at one end, a resilient seat member sitioned in each of saidbase member recesses and engaging the side and inner end walls thereof,
each of said seat members having an outwardly opening hole frictionally receiving one of said holder extensions, the latter being of across sec? tion but slightly greater thanthe cross sectiorrof" the related-hole, and at least one of said chalk holder series and base member being cut away at opposite sides of and adjacent each of said re'' cesseswhereby to provide a relief area to' admit of independent yielding movement of said' chalk-j stick holders in opposite directions transversely of said: recess series.
5; The combination set forth in claim 1, and
said mounting portion having a shoulderin' abut ting engagement with the outer end of said seat member whereby to press the inner end of same against the closed inner end of said recess.-
6. The combination set forth in claim 4, and eachof said chalk: holders providing a shoulder at the inner end of its mounting extension, said shoulder engaging the outer end of saidseat member whereby to'retain'it-in therelated recess.
