The first arcuate slotted aperture receives a first mounting bolt and the second aperture receives a second mounting bolt. A first plurality of vertically-oriented ridges are formed in the back member proximate the first arcuate slotted aperture and the second aperture. A first locking washer is received onto the first mounting bolt. The first locking washer includes a second plurality of vertically-oriented ridges that are complementary to the first plurality of vertically-oriented ridges formed in the back member. The first arcuate slotted aperture facilitates angular adjustment of the back member. Engagement of the second plurality of vertically-oriented ridges with the first plurality of vertically-oriented ridges facilitates securement of the back member in a select angular position. ## Claims ### Claim 1 A curtain-wall anchor, comprising: a back member having a first arcuate slotted aperture and a second aperture formed therein, the first arcuate slotted aperture receiving a first mounting bolt and the second aperture receiving a second mounting bolt; a first plurality of vertically-oriented ridges formed in the back member proximate the first arcuate slotted aperture and the second aperture such that the first arcuate slotted aperture is oriented at a non-perpendicular angle relative to the first plurality of vertically-oriented ridges; a first locking washer that is received onto the first mounting bolt, the first locking washer having a second plurality of vertically-oriented ridges that are complementary to the first plurality of vertically-oriented ridges formed in the back member; wherein, the first arcuate slotted aperture facilitates angular adjustment of the back member; and wherein, engagement of the second plurality of vertically-oriented ridges with the first plurality of vertically-oriented ridges facilitates securement of the back member in a select angular position. ### Claim 2 (depends on 1) The curtain-wall anchor of claim 1, wherein the second aperture is a horizontal slot. ### Claim 3 (depends on 1) The curtain-wall anchor of claim 1, wherein the second aperture is an angled slot. ### Claim 4 (depends on 1) The curtain-wall anchor of claim 1, comprising: a first arm extending from the back member; and a second arm extending from the back member in a spaced relationship to the first arm. ### Claim 5 (depends on 4) The curtain-wall anchor of claim 4, wherein at least one of the first arm and the second arm comprises a plurality of jointed members. ### Claim 6 (depends on 5) The curtain-wall anchor of claim 5, wherein at least one of the first arm and the second arm are slidably coupled to the back member. ### Claim 7 (depends on 6) The curtain-wall anchor of claim 6, wherein at least one of the first arm and the second arm is coupled to the back member via at least one of the first mounting bolt and the second mounting bolt. ### Claim 8 (depends on 7) The curtain-wall anchor of claim 7, wherein the at least one of the first arm and the second arm comprises a fourth plurality of vertically-oriented ridges that are complementary to the first plurality of vertically-oriented ridges. ### Claim 9 A curtain-wall system, comprising: a building structure; a curtain-wall member; a back member coupled to the building structure; a first arm coupled to the back member, the first arm comprising: a first base member; a first intermediate member hingedly coupled to the first base member; a first distal member hingedly coupled to the first intermediate member, the first distal member being coupled to the curtain-wall member; and wherein articulation of the first intermediate member relative to the first base member and articulation of the first distal member relative to the first intermediate member facilitates adjustment of the first arm relative to an as-built location of an edge of the building structure. ### Claim 10 (depends on 9) The curtain-wall system of claim 9, comprising: a first pin coupling the first base member to the first intermediate member; and a second pin coupling the first intermediate member to the first distal member. ### Claim 11 (depends on 9) The curtain-wall system of claim 9, comprising a first locking member that fixes an angular position of the first base member relative to the first intermediate member. ### Claim 12 (depends on 9) The curtain-wall system of claim 9, comprising: a second arm coupled to the back member, the second arm comprising: a second base member; a second intermediate member hingedly coupled to the second base member; and a second distal member hingedly coupled to the second intermediate member, the second distal member being coupled to the curtain-wall member. ### Claim 13 (depends on 12) The curtain-wall system of claim 12, comprising: a third pin coupling the second base member to the second intermediate member; and a fourth pin coupling the second intermediate member to the second distal member. ### Claim 14 (depends on 12) The curtain-wall system of claim 12, comprising a second locking member that fixes an angular position of the second base member relative to the second intermediate member. ### Claim 15 (depends on 12) The curtain-wall system of claim 12, wherein at least one of the first arm and the second arm are slidably coupled to the back member. ### Claim 16 (depends on 9) The curtain-wall system of claim 9, wherein the back member is coupled to a top surface of the building structure. ### Claim 17 (depends on 9) The curtain-wall system of claim 9, wherein the back member is coupled to a front surface of the building structure. ### Claim 18 A method of installing a curtain-wall anchor, the method comprising: securing a back member to a building structure with a first mounting bolt that is received through a first arcuate slotted aperture formed in the back member and with a second mounting bolt that is received through a second aperture formed in the back member, the back member having a first plurality of vertically-oriented ridges formed therein such that the first arcuate slotted aperture is oriented at a non-perpendicular angle relative to the first plurality of vertically-oriented ridges; adjusting, via the first arcuate slotted aperture, an angular position of the back member to a select angular position relative to the building structure; and securing the back member in the select angular position relative to the building structure utilizing a first locking washer, the first locking washer comprising a second plurality of vertically-oriented ridges that are complementary to the first plurality of vertically-oriented ridges such that engagement of the second plurality of vertically-oriented ridges with the first plurality of vertically-oriented ridges impedes angular movement of the back member relative to the building structure. ### Claim 19 (depends on 18) The method of claim 18, wherein the back member is secured to a top surface of the building structure. ### Claim 20 (depends on 18) The method of claim 18, wherein the back member is secured to a front surface of the building structure.
