BY n y WW 3M@ Patented Mar. 15, 1949 u UNITED STATES PATENT OFFICE ABRASIVE STRIP HOLDER Charles W. Booth, San J ose, Calif. Application February 16, 1948, ySerial No. 8,587

1 lThis invention relates to new and useful 'improvements `in illes and the primary object of the present invention is to provide a novel and improved abrasive strip holder.

Another important object of the present invention is to provide an abrasive strip holder including a support applicable` for frictionally engaging an abrasive strip and novel and improved support urging means for retaining the abrasive strip in a tight position on the support.

A furthery object of the present invention is to provide an abrasive strip holder that is extremely small and compact in structure and one that is so designed as to facilitate a strip of abrasive material to be quickly and readily applied thereto or removed therefrom in a convenient l manner.

A still further aim of the present invention is to provide an abrasive strip holder that is simple and practical in construction, strong and reliable in use, neat and attractive in appearance, relatively inexpensive to manufacture 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 side elevational view of the abrasive strip holder constructed in accordance with the present invention, and with parts of the handle portion thereof broken away and shown in section;

Figure 2 is a longitudinal horizontal sectional view taken substantially on the plane of sectionline 2-2 of Figure 1;

Figure 3 is a fragmentary perspective view of one end of the present abrasive strip-holder;

Figure 4 is a perspective view of the lower half of the handle portion used in conjunction with the present invention; and, l,

Figure 5 is an enlarged transverse vertical sectional view taken substantially on the plane of section line 5-5 of Figure 1.

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 II) represents the handle portion of the present abrasive strip holder generally, comprising an upper half I2 and a lower half I4. These halves I2 and I4 are substantially channel shaped in form with their rear portions being provided with transverse ribs I6 4 Claims. (Cl. 51--1873 2 which vare integrally formed with the respective halves. Rigidly secured to or forming an integral .part of the rib I6 for the lower half I4, is a spacer lug I8 having an internally threaded opening 20 that opposes a countersunken aperture 22 provided in the upper half I2. There is provided a further countersunken aperture 24 in the upper half I2 thatregisters with an internally threaded guide sleeve 26 which is xedly secured to the web portion of the lower half I4, adjustably mounted in the lug I8, and the sleeve 26, are fasteners 28 the head portions 30 of which frictionally engage the

apertures

22 and 24.

Slidably positioned on the handle portion I0, is one end of an elongated substantially rectangular support 32 that is provided with a longitudinal guide slot 34 that frictionally engages the guide sleeve 26. Frictionally positioned in

recesses

36 and 38 formed on the lower half and further recesses 40 and 42 provided in the upper half I2 that oppose

recesses

36 and 38, is a pair of

coil springs

44 and 46 which are biased between the ribs I6 and the inner edge 48 of the support 32 to normally urge the support in an extended position relative to the handle portion IIJ.

Preferably integrally formed with the forward open ends of the halves I2 and I4, is a pair of forwardly diverging channeled

extensions

50 and 52 each of which are provided with a pair of transversely extending spaced openings or slots 54 and 55.

In .practical use of the present invention, the support 32 is pushed into the handle until the innermost end 58 of the slot 34 opposes vertical openings 60 and 62 provided in the upper half I2 and the lower half I4, and a pin or the like 64 is extended through the openings 60 and 62 and slot 34 to retain the support 32 in a retracted position. One end 66 cfan elongated strip of abrasive material 68 is then extended upwardly through the slot 54 then downwardly and forwardly through the slot 56 to lace the end 66 to the extension 50. The strip 68 embraces the support 32 and the free end 'I0 thereof is laced through the

slots

54 and 56 of the extension 52. The pin 64 is removed from the handle portion In and the support 32 will be urged forwardly by the

springs

44 and 46 to prevent any looseness or slack in the strip.

In View of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quitev apparent to 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 tive to the handle, recesses provided in the handle,

spring means positioned in the recesses for urging the support in an extended position relative to the handle, a strip of abrasive material embracing the support, means for holding the ends ofthe strip to the handle, said support having a slot, and means detachably carried by said handleen-V gaging said slot for holding the support in a retracted position.

2. The combination of claim 1 wherein said means for holding the ends of the strip to the handle includes a pair of slotted retaining members for interlacing engagement with the ends of the abrasive strip.

3. The combination of claim 1 wherein said means .for holding the support in a retracted position includes an opening provided in said handle, a slot provided in said support registering with said opening when said support is disposed in a retracted position, and a removable pin received in said opening and said slot.

4. The combination of claim 1 wherein said means for guiding and limiting the sliding movement of said support relative to said handle includes a guide sleeve fixed to the web portion of said handle, said support having a longitudinal slot slidablyreceiving said sleeve.
