Adjustable easel

Claim 2

An easel for supporting a rectangular stretcher frame for canvas, comprising a pair of vertical, spaced channel shaped rails having longitudinal slots formed in front sides thereof; upper and lower angle bars for mounting a stretcher frame extending transversely across the channel shaped rails; clamp blocks inside the rails; bolts extending through the slots and engaging said blocks and angle bars for slidably adjusting the angle bars on the rails; a support for mounting the vertical rails in an upright manner comprising a stand including a pair of horizontal base bars; pivot means pivotally securing bottom ends of the rails to said base bars; a first cross bar connecting the base bars; a second cross bar connecting the rails and located between the angle bars; means for adjustably positioning the second cross bar on the rails; and a brace bar pivotally joined at opposite ends to the first and second cross bars so that the rails are adjustably positioned and held angularly with respect to the horizontal base bars, and a palette assembly having a vertical back wall mountable on the lower angle bar so that the palette is adjustably positioned with the lower angle bar along the rails, said palette assembly comprising channel guides integral with said back wall; and a platform plate and a tube support plate slidably and removably engaged in the respective channel guides.

Claim 4

An easel for supporting a rectangular stretcher frame for canvas, comprising a pair of vertical, spaced channel shaped rails having longitudinal slots formed in front sides thereof; upper and lower angle bars for mounting a stretcher frame extending transversely across the channel shaped rails; clamp blocks inside the rails; bolts extending through the slots and engaging said blocks and angle bars for slidably adjusting the angle bars on the rails; a support for mounting the vertical rails in an upright manner comprising a stand including a pair of horizontal base bars; pivot means pivotally securing bottom ends of the rails to said base bars; a first cross bar connecting the base bars; a second cross bar connecting the rails and located between the angle bars; means for adjustably positioning the second cross bar on the rails; and a brace bar pivotally joined at opposite ends to the first and second cross bars so that the rails are adjustably positioned and held angularly with respect to the horizontal base bars, and a palette assembly having a vertical back wall mountable on the lower angle bar so that the palette is adjustably positioned with the lower angle bar along the rails, said palette assembly comprising channel guides integral with said back wall; and a platform plate and a tube support plate slidably and removably engaged in the respective channel guides.

Claim 5

An easel for supporting a rectangular stretcher frame for canvas, comprising a pair of vertical, spaced channel shaped rails having longitudinal slots formed in the front sides thereof; upper and lower angle bars for mounting a stretcher frame extending transversely across the channel shaped rails; clamp blocks inside the rails; bolts extending through the slots and engaging said blocks and angle bars for slidably adjusting the angle bars on the rails, a support for mounting the vertical rails in an upright manner comprising a stand including a pair of horizontal base bars; pivot means pivotally securing bottom ends of the rails to said base bars; a first cross bar connecting the base bars; a second cross bar connecting the rails and located between the angle bars; means for adjustably positioning the second cross bar on the rails; and a brace bar pivotally joined at opposite ends to the first and second cross bars so that the rails are adjustably positioned and held angularly with respect to the horizontal base bars, said base bars having horizontal slots formed therein, said rails having apertures formed near bottom ends thereof, said pivot means comprising other bolts engaged in said horizontal slots so that the rails are slidably and pivotably adjustable on the base bars; a palette assembly having a vertical back wall mountable on the lower angle bar so that the palette is adjustably positioned with the lower angle bar along the rails; said palette assembly further comprising channel guides integral with said back wall; and a platform plate and a tube support plate slidably and removably engaged in the respective channel guides.

Claim 6

An easel for supporting a rectangular stretcher frame for canvas, comprising a pair of vertical, spaced channel shaped rails having longitudinal slots formed in the front sides thereof; upper and lower angle bars for mounting a stretcher frame extending transversely across the channel shaped rails; clamp blocks inside the rails; bolts extending through the slots and engaging said blocks and angle bars for slidably adjusting the angle bars on the rails, a support for mounting the vertical rails in an upright manner comprising a stand including a pair of horizontal base bars; pivot means pivotally securing bottom ends of the rails to said base bars; a first cross bar connecting the base bars; a second cross bar connecting the rails and located between the angle bars; means for adjustably positioning the second cross bar on the rails; and a brace bar pivotally joined at opposite ends to the first and second cross bars so that the rails are adjustably positioned and held angularly with respect to the horizontal base bars, said base bars having horizontal slots formed therein, said rails having apertures formed near bottom ends thereof, said pivot means comprising other bolts engaged in said horizontal slots so that the rails are slidably and pivotably adjustable on the base bars; a palette assembly having a vertical back wall mountable on the lower angle bar so that the palette is adjustably positioned with the lower angle bar along the rails; said palette assembly further comprising channel guides integral with said back wall; and a platform plate and a tube support plate slidably and removably engaged in the respective channel guides.
